awslimitchecker.services.rds module

class awslimitchecker.services.rds._RDSService(warning_threshold, critical_threshold, boto_connection_kwargs, quotas_client)

Bases: awslimitchecker.services.base._AwsService

Describes an AWS service and its limits, and provides methods to query current utilization.

Constructors of _AwsService subclasses must not make any external connections; these must be made lazily as needed in other methods. _AwsService subclasses should be usable without any external network connections.

Parameters:

• warning_threshold (int) – the default warning threshold, as an integer percentage, for any limits without a specifically-set threshold.
• critical_threshold (int) – the default critical threshold, as an integer percentage, for any limits without a specifically-set threshold.
• boto_connection_kwargs (dict) – Dictionary of keyword arguments to pass to boto connection methods.
• quotas_client (ServiceQuotasClient or None) – Instance of ServiceQuotasClient
