Percona Monitoring and Management (PMM)Percona announces the release of Percona Monitoring and Management 1.2.1 on August 16, 2017.

For install and upgrade instructions, see Deploying Percona Monitoring and Management.

This hotfix release improves memory consumption.

Changes in PMM Server

We’ve introduced the following changes in PMM Server 1.2.1:

Bug fixes

  • PMM-1280: PMM server affected by nGinx CVE-2017-7529. An integer overflow exploit could result in a DOS (Denial of Service) for the affected nginx service with the max_ranges directive not set. This problem is solved by setting the set max_ranges directive to 1 in the nGinx configuration.

Improvements

  • PMM-1232: Update the default value of the METRICS_MEMORY configuration 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-size has been set to 768 MB.
