Adaptive multi-tenant monitoring in resource constrained environments

A computer program product comprising a computer readable storage medium having a computer readable program stored therein, wherein the computer readable program, when executed by a processor, causes the processor to:

• detect occurrence of a trigger event;
• modify, in response to detecting occurrence of the trigger event, a selection of metrics included in a plurality of monitored metrics that are monitored using available resources of a plurality of tenants, each metric associated with at least one of the plurality of tenants;
• assign a respective monitoring frequency for each metric included in the modified selection of metrics;
• compute respective weights for each metric in the modified selection of metrics;
• perform a check to determine if the available resources of the plurality of tenants can achieve the monitoring of the modified selection of metrics at the respective assigned monitoring frequency for each metric included in the modified selection of metrics;
• in response to determining that the available resources of the plurality of tenants cannot achieve the monitoring of the modified selection of metrics at the respective assigned monitoring frequency, adjust the respective monitoring frequency for one or more metrics in the modified selection of metrics based, at least in part, on the respective weight for each metric and on the at least one tenant associated with each metric until it is determined that the available resources of the plurality of tenants is able to achieve the monitoring for each metric included in the modified selection of metrics at the respective adjusted monitoring frequency;
• and
• in response to determining that the available resources of the plurality of tenants can achieve the monitoring of the modified selection of metrics, allocate processing associated with monitoring each metric in the modified selection of metrics among the available resources of the plurality of tenants based on the respective monitoring frequency of each metric and based on the at least one tenant associated with each metric.

A multi-tenant monitor device comprising:

• an interface configured to communicatively couple the multi-tenant monitor device to a plurality of tenant devices, wherein each of the plurality of tenant devices is associated with at least one tenant;
• a processor communicatively coupled to the interface and configured to:
• detect occurrence of a trigger event;
• modify, in response to detecting occurrence of the trigger event, a selection of metrics included in a plurality of monitored metrics that are monitored using available resources of a plurality of tenants, each metric associated with at least one of the plurality of tenants;
• assign a respective monitoring frequency for each metric included in the modified selection of metrics;
• compute respective weights for each metric in the modified selection of metrics;
• perform a check to determine if the available resources of the plurality of tenants can achieve the monitoring of the modified selection of metrics at the respective assigned monitoring frequency for each metric included in the modified selection of metrics;
• in response to determining that the available resources of the plurality of tenants cannot achieve the monitoring of the modified selection of metrics at the respective assigned monitoring frequency, adjust the respective monitoring frequency for one or more metrics in the modified selection of metrics based, at least in part, on the respective weight for each metric and on the at least one tenant associated with each metric until it is determined that the available resources of the plurality of tenants is able to achieve the monitoring for each metric included in the modified selection of metrics at the respective adjusted monitoring frequency;
• and
• in response to determining that the available resources of the plurality of tenants can achieve the monitoring of the modified selection of metrics, allocate processing associated with monitoring each metric in the modified selection of metrics among the available resources of the plurality of tenants based on the respective monitoring frequency of each metric and based on the at least one tenant associated with each metric.
