Percona Monitoring and Management 1.8.0 Is Now Available

The latest release of Percona Monitoring and Management (PMM) 1.8.0 is available as of February 27, 2018.

Percona Monitoring and Management is a free and open-source platform for managing and monitoring MySQL and MongoDB performance. You can run PMM in your own environment for maximum security and reliability. It provides thorough time-based analysis for MySQL and MongoDB servers to ensure that your data works as efficiently as possible.

This release introduces many improvements in the user interface and optimizations of performance.

New landing page


The home page has been removed in favor of the Home dashboard to make the look and feel of PMM web interface more consistent. The Home dashboard gives a general overview of your system and provides links to useful resources. You can immediately go to a dashboard of your choice either by using the conventional Dashboard drop down at the top of the page or the new dashboard menu.

The new dashboard menu provides a convenient grouping of dashboards making the switching between dashboards easy: select a group, such as MySQL or OS, and choose from a short list in the menu that opens. The new dashboard menu is available from every dashboard in PMM.

Memory improvements


This release also features improved memory usage on the host system in PMM Server. By default PMM now automatically scales its use with system size rather than using static amount of memory, unless you explicitly set the maximum value (by using the METRICS_MEMORY option in Docker, for example).


New Features
  • PMM-1145: Move Percona Dashboards to Grafana Plugin
    We have updated the Percona Dashboards to use the Grafana Plugins system in order to simplify upgrades.
  • PMM-1470: Implement a Custom Prometheus rds_exporter to Collect Amazon CloudWatch Metrics
    You can now explore CloudWatch metrics from Prometheus, for example using the Advanced Data Exploration dashboard. In prior versions we were using CloudWatch API calls directly.
  • PMM-2046: Configure Memory Consumption Automatically for PMM Server
    In this release we improved memory usage in PMM Server. By default PMM now automatically scales its use with system size rather than using static amount of memory. You can override this behaviour, for example if you need to share resources with other containers by using the METRICS_MEMORY option in Docker. You can use the old static size of memory by running:


1
docker ... -e METRICS_MEMORY=786432


Improvements
  • PMM-1425: Replace the Home Page with the Home Dashboard
    The home page has been removed in favor of the Home dashboard to make the look and feel of PMM web interface more consistent. The Home dashboard gives a general overview of your system and provides links to useful resources. You can immediately go to a dashboard of your choice either by using the conventional Dashboard drop down at the top of the page or the new dashboard menu.
