Percona announces the release of Percona Monitoring and Management 1.0.2 Beta on 28 July 2016.

Like prior versions, PMM is distributed through Docker Hub and is free to download. Full instructions for download and installation of the server and client are available in the documentation.

Notable changes to the tool include:

• Upgraded to Grafana 3.1.0.
• Upgraded to Prometheus 1.0.1.
• Set default metrics retention to 30 days.
• Eliminated port 9001. Now the container uses only one configurable port, 80 by default.
• Eliminated the need to specify ADDRESS variable when creating Docker container.
• Completely re-wrote pmm-admin with more functions.
• Added ability to stop all services using the new pmm-admin.
• Added support to name instances using the new pmm-admin.
• Query Analytics Application updates:
  • Redesigned queries profile table
  • Redesigned metrics table
  • Redesigned instance settings page
  • Added sparkline charts
  • Added ability to show more than ten queries
• Various updates for MongoDB dashboards.

The full release notes are available in the documentation. The documentation also includes details on installation and architecture.

A demonstration of the tool has been set up at pmmdemo.percona.com.

We have also implemented forums for the discussion of PMM.

Help us improve our software quality by reporting any bugs you encounter using our bug tracking system. As always, thanks for your continued support of Percona!

Some screen shots of the updates:

Note the new sparkline that shows the current load in context (so you know if the number is higher/normal/lower than normal), and the option to “Load next 10 queries” at the bottom of the listing.

Our admin tool was completely re-written with new functions:

pmm-admin –help output

 

pmm-admin list command output

 

pmm-admin check-network output, which provides information on the status of the client’s network connection to the server.

Join Brent Compton, Kyle Bader and Yves Trudeau on August 2, 2016 at 10 am PDT (UTC-7) for a MySQL and Ceph webinar.

Many operators select OpenStack as their control plane of choice for providing both internal and external IT services. The OpenStack user survey repeatedly shows Ceph as the dominant backend for providing persistent storage volumes through OpenStack Cinder. When building applications and repatriating old workloads, developers are discovering the need to provide OpenStack infrastructure database services. Given MySQL’s ubiquity, and it’s reliance on persistent storage, it is of utmost importance to understand how to achieve the performance demanded by today’s applications. Databases like MySQL can be incredibly IO intensive, and Ceph offers a great opportunity to go beyond the limitations presented by a single scale-up system. Since Ceph provides a mutable object store with atomic operations, could MySQL store InnoDB pages directly in Ceph?

This talk reviews the general architecture of Ceph, and then discusses benchmark results from small to mid-size Ceph clusters. These benchmarks lead to the development of prescriptive guidance around tuning Ceph storage nodes (OSDs), the impact the amount of physical memory, and the presence of SSDs, high-speed networks or RAID controllers.
