This hotfix release improves memory consumption
The following changes were introduced in PMM Server 1.2.1:
An integer overflow exploit could result in a DOS (Denial of Service) for the affected nginx service with the
max_rangesdirective not set.
This problem is solved by setting the
set max_rangesdirective to 1 in the nGinx configuration.
PMM-1232: Update the default value of the
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 being 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.
