This hotfix release improves memory consumption.
Changes in PMM Server
We’ve introduced the following changes in PMM Server 1.2.1:
PMM-1232: Update the default value of the
METRICS_MEMORYconfiguration setting. Previous versions of PMM Server used a different value for the METRICS_MEMORY configuration setting which allowed Prometheus to use up to 768MB of memory. PMM Server 1.2.0 used the storage.local.target-heap-size setting, its default value is 256MB. Unintentionally, this value reduced the amount of memory that Prometheus could use. As a result, the performance of Prometheus was affected. To improve the performance of Prometheus, the default setting of
storage.local.target-heap-sizehas been set to 768 MB.
