Percona Monitoring and Management 1.5.2 Is Now Available

Percona announces the release of Percona Monitoring and Management 1.5.2. This release contains fixes to bugs found after Percona Monitoring and Management 1.5.1 was released.

Bug fixes

  • PMM-1790QAN displayed query metrics even for a host that was not configured for mysql:queries or mongodb:queries. We have fixed the behaviour to display an appropriate warning message when there are no query metrics for the selected host.
  • PMM-1826: If PMM Server 1.5.0 is deployed via Docker, the Update button would not upgrade the instance to a later release.

Percona Monitoring and Management 1.5: QAN in Grafana Interface

In this post, we’ll examine how we’ve improved the GUI layout for Percona Monitoring and Management 1.5 by moving the Query Analytics (QAN) functions into the Grafana interface.

For Percona Monitoring and Management users, you might notice that QAN appears a little differently in our 1.5 release. We’ve taken steps to unify the PMM interface so that it feels more natural to move from reviewing historical trends in Metrics Monitor to examining slow queries in QAN.  Most significantly:

  1. QAN moves from a stand-alone application into Metrics Monitor as a dashboard application
  2. We updated the color scheme of QAN to match Metrics Monitor (but you can toggle a button if you prefer to still see QAN in white!)
  3. Date picker and host selector now use the same methods as Metrics Monitor

Percona Monitoring and Management 1.4.0 Is Now Available

Percona announces the release of Percona Monitoring and Management 1.4.0.

This release introduces the support of external Prometheus exporters so that you can create dashboards in the Metrics monitor even for the monitoring services other than those provided with PMM client packages.

How to Choose the MySQL innodb_log_file_size

In this blog post, I’ll provide some guidance on how to choose the MySQL innodb_log_file_size.

Like many database management systems, MySQL uses logs to achieve data durability (when using the default InnoDB storage engine). This ensures that when a transaction is committed, data is not lost in the event of crash or power loss.

MySQL’s InnoDB storage engine uses a fixed size (circular) Redo log space. The size is controlled by innodb_log_file_size and innodb_log_files_in_group (default 2). You multiply those values and get the Redo log space that available to use. While technically it shouldn’t matter whether you change either the innodb_log_file_size or innodb_log_files_in_group variable to control the Redo space size, most people just work with the innodb_log_file_size and leave innodb_log_files_in_group alone.
