Changelog

6.0.1 (2019-01-27)

6.0.0 (2019-01-01)

This release requires new IAM permissions:

  • lambda:GetAccountSettings

Important: This release removes the ApiGateway APIs per account limit in favor of more-specific limits; see below.

  • Issue #363 - Add support for the Lambda limits and usages.
  • Clarify support for “unlimited” limits (limits where awslimitchecker.limit.AwsLimit.get_limit() returns None).
  • Add support for 26 new EC2 instance types.
  • Update default limits for ECS service.
  • ApiGateway service now has three ReST API limits (Regional API keys per account, Private API keys per account, and Edge API keys per account) in place of the previous single APIs per account to reflect the current documented service limits.
  • API Gateway service - add support for VPC Links per account limit.
  • Add support for Network Load Balancer limits Network load balancers and Listeners per network load balancer.
  • Add support for Application Load Balancer limits Certificates per application load balancer.
  • Add support for Classic ELB (ELBv1) Registered instances per load balancer limit.
  • Rename dev/terraform.py to dev/update_integration_iam_policy.py and move from using terraform to manage integration test IAM policy to pure Python.
  • Note that I’ve left out the Targets per application load balancer and Targets per network load balancer limits. Checking usage for these requires iterating over DescribeTargetHealth for each target group, so I’ve opted to leave it out at this time for performance reasons and because I’d guess that the number of people with 500 or 1000 targets per LB is rather small. Please open an issue if you’d like to see usage calculation for these limits.

Important Note on Limit Values

awslimitchecker has had documented support for Limits that are unlimited/”infinite” since 0.5.0 by returning None from awslimitchecker.limit.AwsLimit.get_limit(). Until now, that edge case was only triggered when Trusted Advisor returned “Unlimited” for a limit. It will now also be returned for the Lambda service’s Function Count Limit. Please be aware of this if you’re using the Python API and assuming Limit values are all numeric.

If you are relying on the output format of the command line awslimitchecker script, please use the Python API instead.

5.1.0 (2018-09-23)

  • Issue #358 - Update EFS with new default limit for number of File systems: 70 in us-east-1 and 125 in other regions.
  • PR #359 - Add support for t3 EC2 instance types (thanks to chafouin).
  • Switch py37 TravisCI tests from py37-dev to py37 (release).

5.0.0 (2018-07-30)

This release requires new IAM permissions:

  • cloudtrail:DescribeTrails
  • cloudtrail:GetEventSelectors
  • route53:GetHostedZone
  • route53:ListHostedZones
  • route53:GetHostedZoneLimit

This release officially drops support for Python 2.6 and 3.3.

  • PR #345 / Issue #349 - Add Route53 service and checks for “Record sets per hosted zone” and “VPC associations per hosted zone” limits (the latter only for private zones). (thanks to julienduchesne).
  • Support Per-Resource Limits (see below). Note that this includes some changes to the ``awslimitchecker`` CLI output format and some minor API changes.
  • Issue #317 - Officially drop support for Python 2.6 and 3.3. Also, begin testing py37.
  • Issue #346 - Update documentation for S3 API calls made by ElasticBeanstalk while retrieving EB limits (thanks to fenichelar for finding this).
  • PR #350 - Add support for CloudTrail limits (thanks to fpiche).
  • Issue #352 - Update version check PyPI URL and set User-Agent when performing version check.
  • Issue #351 - Add support for forty two (42) missing EC2 instance types including the new c5d/m5d/r5d/z1d series instances.

Per-Resource Limits

Some Limits (AwsLimit) now have limits/maxima that are per-resource rather than shared across all resources of a given type. The first limit of this kind that awslimitchecker supports is Route53, where the “Record sets per hosted zone” and “VPC associations per hosted zone” limits are set on a per-resource (per-zone) basis rather than globally to all zones in the account. Limits of this kind are also different since, as they are per-resource, they can only be enumerated at runtime. Supporting limits of this kind required some changes to the internals of awslimitchecker (specifically the AwsLimit and AwsLimitUsage classes) as well as to the output of the command line script/entrypoint.

For limits which support different maxima/limit values per-resource, the command line awslimitchecker script -l / --list-limits functionality will now display them in Service/Limit/ResourceID format, i.e.:

Route53/Record sets per hosted zone/foo.com                  10000 (API)
Route53/Record sets per hosted zone/bar.com                  10000 (API)
Route53/Record sets per hosted zone/local.                   15000 (API)
Route53/VPC associations per hosted zone/local.              100 (API)

As opposed to the Service/Limit format used for all existing limits, i.e.:

IAM/Groups             300 (API)
IAM/Instance profiles  2000 (API)

If you are relying on the output format of the command line awslimitchecker script, please use the Python API instead.

For users of the Python API, please take note of the new AwsLimit.has_resource_limits() and get_maximum() methods which assist in how to identify limits that have per-resource maxima. Existing code that only surfaces awslimitchecker’s warnings/criticals (the result of check_thresholds()) will work without modification, but any code that displays or uses the current limit values themselves may need to be updated.

4.0.2 (2018-03-22)

This is a minor bugfix release for one issue:

  • Issue #341 - The Trusted Advisor EBS checks for General Purpose (SSD) volume storage (GiB) and Magnetic volume storage (GiB) have been renamed to to General Purpose SSD (gp2) volume storage (GiB) and Magnetic (standard) volume storage (GiB), respectively, to provide more unified naming. This change was made on March 19th or 20th without any public announcement, and resulted in awslimitchecker being unable to determine the current values for these limits from Trusted Advisor. Users relying on Trusted Advisor for these values saw the limit values incorrectly revert to the global default. This is an internal-only change to map the new Trusted Advisor check names to the awslimitchecker limit names.

4.0.1 (2018-03-09)

This is a minor bugfix release for a few issues that users have reported recently.

  • Fix Issue #337 where sometimes an account even with Business-level support will not have a Trusted Advisor result for the Service Limits check, and will return a result with status: not_available or a missing flaggedResources key.
  • Fix Issue #335 where runs against the EFS service in certain unsupported regions result in either a connection timeout or an AccessDeniedException.

4.0.0 (2018-02-17)

This release requires new IAM permissions:

  • ds:GetDirectoryLimits
  • ecs:DescribeClusters
  • ecs:DescribeServices
  • ecs:ListClusters
  • ecs:ListServices
  • Fix various docstring problems causing documentation build to fail.
  • PR #328 - Add support for Directory Service and ECS (thanks to di1214).
    • NOTE the “EC2 Tasks per Service (desired count)” limit uses non-standard resource IDs, as service names and ARNs aren’t unique by account or region, but only by cluster. i.e. the only way to uniquely identify an ECS Service is by the combination of service and cluster. As such, the resource_id field for usage values of the “EC2 Tasks per Service (desired count)” limit is a string of the form cluster=CLUSTER-NAME; service=SERVICE-NAME.
  • PR #330 - Update numerous no-longer-correct default limits (thanks to GitHub user KingRogue).
    • AutoScaling
      • Auto Scaling groups - 20 to 200
      • Launch configurations - 100 to 200
    • EBS
      • Provisioned IOPS - 40000 to 200000
      • Provisioned IOPS (SSD) storage (GiB) - 20480 to 102400 (100 TiB)
      • General Purpose (SSD) volume storage (GiB) - 20480 to 102400 (100 TiB)
      • Throughput Optimized (HDD) volume storage (GiB) - 20480 to 307200 (300 TiB)
      • Cold (HDD) volume storage (GiB) - 20480 to 307200 (300 TiB)
    • ElasticBeanstalk
      • Applications - 25 to 75
      • Application versions - 500 to 1000
    • IAM
      • Groups - 100 to 300
      • Roles - 250 to 1000
      • Instance profiles - 100 to 1000
      • Policies - 1000 to 1500
  • Fix dev/terraform.py and dev/integration_test_iam.tf for integration tests.
  • Fix date and incorrect project name in some file/copyright headers.
  • Issue #331 - Change layout of the generated Supported Limits documentation page to be more clear about which limits are supported, and include API and Trusted Advisor data in the same table as the limits and their defaults.

3.0.0 (2017-12-02)

Important Notice for python 2.6 and 3.3 users:

Python 2.6 reached its end of life in October 2013. Python 3.3 officially reached its end of life in September 2017, five years after development was ceased. The test framework used by awslimitchecker, pytest, has dropped support for Python 2.6 and 3.3 in its latest release. According to the PyPI download statistics (which unfortunately don’t take into account mirrors or caching proxies), awslimitchecker has only ever had one download reported as Python 3.3 and has a very, very small number reporting as Python 2.6 (likely only a handful of users). The next release of awslimitchecker will officially drop support for Python 2.6 and 3.3, changing the required Python version to 2.7 or >= 3.4. If you are one of the very few (perhaps only one) users running on Python 2.6, you can either run with a newer Python version or see Issue 301 for information on building a Docker container based on Python 3.5.

  • Fix test failures caused by dependency updates.
  • Pin pytest development to 3.2.5 to continue python 2.6 and 3.3 support.
  • Issue #314 - Update RDS service default limits; DB snapshots per user default limit increased from 50 to 100 and Subnet Groups limit increased from 20 to 50. This should not have affected any users, as these limits are retrieved in realtime via the RDS API.
  • Issue #293 - Increase maximum number of retries (boto3/botocore) for elbv2 API calls, to attempt to deal with the large number of calls we have to make in order to count the ALB listeners and rules. This requires botocore >= 1.6.0, which requires boto3 >= 1.4.6.
  • Issue #315 - Add new instance types: ‘c5.18xlarge’, ‘c5.2xlarge’, ‘c5.4xlarge’, ‘c5.9xlarge’, ‘c5.large’, ‘c5.xlarge’, ‘g3.16xlarge’, ‘g3.4xlarge’, ‘g3.8xlarge’, ‘h1.16xlarge’, ‘h1.2xlarge’, ‘h1.4xlarge’, ‘h1.8xlarge’, ‘m5.12xlarge’, ‘m5.24xlarge’, ‘m5.2xlarge’, ‘m5.4xlarge’, ‘m5.large’, ‘m5.xlarge’, ‘p3.16xlarge’, ‘p3.2xlarge’, ‘p3.8xlarge’, ‘x1e.32xlarge’, ‘x1e.xlarge’
  • Issue #316 - Automate release process.

2.0.0 (2017-10-12)

  • Update README with correct boto version requirement. (Thanks to nadlerjessie for the contribution.)
  • Update minimum boto3 version requirement from 1.2.3 to 1.4.4; the code for Issue #268 released in 0.11.0 requires boto3 >= 1.4.4 to make the ElasticLoadBalancing DescribeAccountLimits call.
  • Bug fix for “Running On-Demand EC2 instances” limit - Issue #308 - The fix for Issue #215 / PR #223, released in 0.6.0 on November 11, 2016 was based on incorrect information about how Regional Benefit Reserved Instances (RIs) impact the service limit. The code implemented at that time subtracted Regional Benefit RIs from the count of running instances that we use to establish usage. Upon further review, as well as confirmation from AWS Support, some AWS TAMs, and the relevant AWS documentation, only Zonal RIs (AZ-specific) are exempt from the Running On-Demand Instances limit. Regional Benefit RIs are counted the same as any other On-Demand Instances, as they don’t have reserved capacity. This release stops subtracting Regional Benefit RIs from the count of Running Instances, which was causing awslimitchecker to report inaccurately low Running Instances usage.

0.8.0 (2017-03-11)

This release includes a breaking API change. Please see the first bullet point below. Note that once 1.0.0 is released (which should be relatively soon), such API changes will only come with a major version increment.

This release requires new IAM permissions: redshift:DescribeClusterSnapshots and redshift:DescribeClusterSubnetGroups.

This release removes Python 3.2 support. This was deprecated in 0.7.0. As of this release, awslimitchecker may still work on Python 3.2, but it is no longer tested and any support tickets or bug reports specific to 3.2 will be closed.

  • PR #250 - Allow the --service command line option to accept multiple values. This is a breaking public API change; the awslimitchecker.checker.AwsLimitChecker awslimitchecker.checker.AwsLimitChecker.check_thresholds, awslimitchecker.checker.AwsLimitChecker.find_usage, and awslimitchecker.checker.AwsLimitChecker.get_limits methods now take an optional service list keyword argument instead of a string for a single service name.
  • PR #251 - Handle GovCloud-specific edge cases; specifically, UnsupportedOperation errors for EC2 Spot Instance-related API calls, and limits returned as 0 by the DescribeAccountAttributes EC2 API action.
  • PR #249 - Add support for RedShift limits (Redshift subnet groups and Redshift manual snapshots). This requires the redshift:DescribeClusterSnapshots and redshift:DescribeClusterSubnetGroups IAM permissions.
  • Issue #259 - remove duplicates from required IAM policy returned by awslimitchecker.checker.AwsLimitChecker.get_required_iam_policy and awslimitchecker --iam-policy.
  • Various TravisCI/tox build fixes:
    • Fix pip caching; use default pip cache directory
    • Add python 3.6 tox env and Travis env, now that it’s released
    • Switch integration3 tox env from py3.4 to py3.6
  • PR #256 - Add example of wrapping awslimitchecker in a script to send metrics to Prometheus.
  • Issue #236 - Drop support for Python 3.2; stop testing under py32.
  • Issue #257 - Handle ElastiCache DescribeCacheCluster responses that are missing CacheNodes key in a cluster description.
  • Issue #200 - Remove EC2 Spot Instances/Fleets limits from experimental status.
  • Issue #123 - Update documentation on using session tokens (Session or Federation temporary creds).

0.7.0 (2017-01-15)

This release deprecates support for Python 3.2. It will be removed in the next release.

This release introduces support for automatically refreshing Trusted Advisor checks on accounts that support this. If you use this new feature, awslimitchecker will require a new permission, trustedadvisor:RefreshCheck. See Getting Started - Trusted Advisor for further information.

  • #231 - add support for new f1, r4 and t2.(xlarge|2xlarge) instance types, introduced in November 2016.
  • #230 - replace the built-in versioncheck.py with versionfinder. Remove all of the many versioncheck tests.
  • #233 - refactor tests to replace yield-based tests with parametrize, as yield-based tests are deprecated and will be removed in pytest 4.
  • #235 - Deprecate Python 3.2 support. There don’t appear to have been any downloads on py32 in the last 6 months, and the effort to support it is too high.
  • A bunch of Sphinx work to use README.rst in the generated documentation.
  • Changed DEBUG-level logging format to include timestamp.
  • #239 - Support refreshing Trusted Advisor check results during the run, and optionally waiting for refresh to finish. See Getting Started - Trusted Advisor for further information.
  • #241 / PR #242 - Fix default ElastiCache/Nodes limit from 50 to 100, as that’s now what the docs say.
  • #220 / PR #243 / PR #245 - Fix for ExpiredTokenException Errors. awslimitchecker.connectable.credentials has been removed. In previous releases, awslimitchecker had been using a Connectable.credentials class attribute to store AWS API credentials and share them between Connectable subclass instances. The side-effect of this was that AWS credentials were set at the start of the Python process and never changed. For users taking advantage of the Python API and either using short-lived STS credentials or using long-running or threaded implementations, the same credentials persisted for the life of the process, and would often result in ExpiredTokenExceptions. The fix was to move _boto_conn_kwargs and _get_sts_token from connectable to the top-level AwsLimitChecker class itself, get the value of the _boto_conn_kwargs property in the constructor, and pass that value in to all Connectable subclasses. This means that each instance of AwsLimitChecker has its own unique connection-related kwargs and credentials, and constructing a new instance will work intuitively - either use the newly-specified credentials, or regenerate STS credentials if configured to use them. I have to extend my deepest gratitude to the folks who identified and fixed this issue, specifically cstewart87 for the initial bug report and description, aebie for the tireless and relentlessly thorough investigation and brainstorming and for coordinating work for a fix, and willusher for the final implementation and dealing (wonderfully) with the dizzying complexity of many of the unit tests (and even matching the existing style).

0.6.0 (2016-11-12)

This release has a breaking change. The VPC NAT gateways has been renamed to NAT Gateways per AZ and its get_current_usage() method will now return a list with multiple items. See the changelog entry for #214 below.

This release requires the following new IAM permissions to function:

  • firehose:ListDeliveryStreams
  • #217 - add support for new/missing EC2 instance types: m4.16xlarge, x1.16xlarge, x1.32xlarge, p2.xlarge, p2.8xlarge, p2.16xlarge.
  • #215 - support “Regional Benefit” Reserved Instances that have no specific AZ set on them. Per AWS, these are exempt from On-Demand Running Instances limits like all other RIs.
  • #214 - The VPC “NAT gateways” limit incorrectly calculated usage for the entire region, while the limit is actually per-AZ. It also had strange capitalization that confused users. The name has been changed to “NAT Gateways per AZ” and the usage is now correctly calculated per-AZ instead of region-wide.
  • #221 / PR #222 - Fix bug in handling of STS Credentials where they are cached permanently in connectable.Connectable.credentials, and new AwsLimitChecker instances in the same Python process reuse the first set of STS credentials. This is fixed by storing the Account ID as part of connectable.ConnectableCredentials and getting new STS creds if the cached account ID does not match the current account_id on the Connectable object.
  • PR #216 - add new “Firehose” service with support for “Delivery streams per region” limit.
  • #213 / PR #188 - support AWS cross-sdk credential file profiles via -P / --profile, like awscli.

0.5.1 (2016-09-25)

This release requires the following new IAM permissions to function:

  • ec2:DescribeSpot* or more specifically:
    • ec2:DescribeSpotDatafeedSubscription
    • ec2:DescribeSpotFleetInstances
    • ec2:DescribeSpotFleetRequestHistory
    • ec2:DescribeSpotFleetRequests
    • ec2:DescribeSpotInstanceRequests
    • ec2:DescribeSpotPriceHistory
  • ec2:DescribeNatGateways
  • #51 / PR #201 - Add experimental support for Spot Instance and Spot Fleet limits (only the ones explicitly documented by AWS). This is currently experimental, as the documentation is not terribly clear or detailed, and the author doesn’t have access to any accounts that make use of spot instances. This will be kept experimental until multiple users validate it. For more information, see the EC2 limit documentation.
  • PR #204 contributed by hltbra to add support for VPC NAT Gateways limit.
  • Add README and Docs link to waffle.io board.
  • Fix bug where --skip-ta command line flag was ignored in show_usage() (when running with -u / --show-usage action).
  • Add link to waffle.io Kanban board
  • #202 - Adds management of integration test IAM policy via Terraform.
  • #211 - Add working download stats to README and docs
  • Fix broken landscape.io badges in README and docs
  • #194 - On Limits page of docs, clarify that Running On-Demand Instances does not include Reserved Instances.
  • Multiple tox.ini changes:
    • simplify integration and unit/versioncheck testenv blocks using factors and reuse
    • py26 testenv was completely unused, and py26-unit was running and working with mock==2.0.0
    • use pytest<3.0.0 in py32 envs
  • #208 - fix KeyError when timestamp key is missing from TrustedAdvisor check result dict

0.5.0 (2016-07-06)

This release includes a change to awslimitchecker’s Python API. awslimitchecker.limit.AwsLimit.get_limit can now return either an int or None, as TrustedAdvisor now lists some service limits as being explicitly “unlimited”.

  • #195 - Handle TrustedAdvisor explicitly reporting some limits as “unlimited”. This introduces the concept of unlimited limits, where the effective limit is None.

0.4.4 (2016-06-27)

  • PR #190 / #189 - Add support for EBS st1 and sc1 volume types (adds “EBS/Throughput Optimized (HDD) volume storage (GiB)” and “EBS/Cold (HDD) volume storage (GiB)” limits).

0.4.3 (2016-05-08)

0.4.2 (2016-04-27)

This release requires the following new IAM permissions to function:

  • elasticbeanstalk:DescribeApplications
  • elasticbeanstalk:DescribeApplicationVersions
  • elasticbeanstalk:DescribeEnvironments
  • #70 Add support for ElasicBeanstalk service.
  • #177 Integration tests weren’t being properly skipped for PRs.
  • #175 the simplest and most clear contributor license agreement I could come up with.
  • #172 add an integration test running against sa-east-1, which has fewer services than the popular US regions.

0.4.1 (2016-03-15)

  • #170 Critical bug fix in implementation of #71 - SES only supports three regions (us-east-1, us-west-2, eu-west-1) and causes an unhandled connection error if used in another region.

0.4.0 (2016-03-14)

This release requires the following new IAM permissions to function:

  • rds:DescribeAccountAttributes
  • iam:GetAccountSummary
  • s3:ListAllMyBuckets
  • ses:GetSendQuota
  • cloudformation:DescribeAccountLimits
  • cloudformation:DescribeStacks

Issues addressed:

  • #150 add CHANGES.rst to Sphinx docs

  • #85 and #154

    • add support for RDS ‘DB Clusters’ and ‘DB Cluster Parameter Groups’ limits
    • use API to retrieve RDS limits
    • switch RDS from calculating usage to using the DescribeAccountAttributes usage information, for all limits other than those which are per-resource and need resource IDs (Max auths per security group, Read replicas per master, Subnets per Subnet Group)
    • awslimitchecker now requires an additional IAM permission, rds:DescribeAccountAttributes
  • #157 fix for TrustedAdvisor polling multiple times - have TA set an instance variable flag when it updates services after a poll, and skip further polls and updates if the flag is set. Also add an integration test to confirm this.

  • #50 Add support for IAM service with a subset of its limits (Groups, Instance Profiles, Policies, Policy Versions In Use, Roles, Server Certificates, Users), using both limits and usage information from the GetAccountSummary API action. This requires an additional IAM permission, iam:GetAccountSummary.

  • #48 Add support for S3 Buckets limit. This requires an additional IAM permission, s3:ListAllMyBuckets.

  • #71 Add support for SES service (daily sending limit). This requires an additional IAM permission, ses:GetSendQuota.

  • #69 Add support for CloudFormation service Stacks limit. This requires additional IAM permissions, cloudformation:DescribeAccountLimits and cloudformation:DescribeStacks.

  • #166 Speed up TravisCI tests by dropping testing for PyPy and PyPy3, and only running the -versioncheck tests for two python interpreters instead of 8.

0.3.2 (2016-03-11)

  • #155 Bug fix for uncaught KeyError on accounts with Trusted Advisor (business-level support and above). This was caused by an undocumented change released by AWS between Thu, 10 Mar 2016 07:00:00 GMT and Fri, 11 Mar 2016 07:00:00 GMT, where five new IAM-related checks were introduced that lack the region data field (which the TrustedAdvisorResourceDetail API docs still list as a required field).

0.3.1 (2016-03-04)

  • #117 fix Python 3.5 TravisCI tests and re-enable automatic testing for 3.5.
  • #116 add t2.nano EC2 instance type; fix typo - “m4.8xlarge” should have been “m4.10xlarge”; update default limits for m4.(4|10)xlarge
  • #134 Minor update to project description in docs and setup.py; use only _VERSION (not git) when building in RTD; include short description in docs HTML title; set meta description on docs index.rst.
  • #128 Update Development and Getting Help documentation; add GitHub CONTRIBUTING.md file with link back to docs, as well as Issue and PR templates.
  • #131 Refactor TrustedAdvisor interaction with limits for special naming cases (limits where the TrustedAdvisor service or limit name doesn’t match that of the awslimitchecker limit); enable newly-available TrustedAdvisor data for some EC2 on-demand instance usage.

0.3.0 (2016-02-18)

  • Add coverage for one code branch introduced in PR #100 that wasn’t covered by tests.
  • #112 fix a bug in the versioncheck integration tests, and a bug uncovered in versioncheck itself, both dealing with checkouts that are on a un-cloned branch.
  • #105 build and upload wheels in addition to sdist
  • #95 major refactor to convert AWS client library from boto to boto3. This also includes significant changes to the internal connection logic and some of the internal (private) API. Pagination has been moved to boto3 wherever possible, and handling of API request throttling has been removed from awslimitchecker, as boto3 handles this itself. This also introduces full, official support for python3.
  • Add separate localdocs tox env for generating documentation and updating output examples.
  • #113 update, expand and clarify documentation around threshold overrides; ignore some sites from docs linkcheck.
  • #114 expanded automatic integration tests
  • Please note that version 0.3.0 of awslimitchecker moved from using boto as its AWS API client to using boto3. This change is mostly transparent, but there is a minor change in how AWS credentials are handled. In boto, if the AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY environment variables were set, and the region was not set explicitly via awslimitchecker, the AWS region would either be taken from the AWS_DEFAULT_REGION environment variable or would default to us-east-1, regardless of whether a configuration file (~/.aws/credentials or ~/.aws/config) was present. With boto3, it appears that the default region from the configuration file will be used if present, regardless of whether the credentials come from that file or from environment variables.
