Percona Agent 1.0.11

Percona is glad to announce the release of Percona Agent 1.0.11 on February 24th 2015. Downloads are available from our download site here. Percona Agent can be installed or updated as described in the manual.

New Features

  • Query Analytics for Performance Schema has been rewritten.
  • Percona Agent now collects all Performance schema metrics.
  • Percona Agent user can now be added to the server which has old_passwords option enabled by installing the agent with the --old-passwords command option.
  • Percona Agent now supports using EXPLAIN for non SELECT queries in Query Analytics as well.

Bugs Fixed

  • Percona Agent was truncating Perfomance Schema tables which could issues for other applications using the Performance Schema.
  • Percona Agent init script now verifies if running binary under PID file corresponds to percona-agent instance.
  • Existing Percona Agent PID file didn’t prevent second instance of the agent being started.
  • Metrics Monitoring value lap information was logged as error instead of information.
  • If the slow query log contained a line with a malformed Timestamp or User fields, Query Analytics slow log parser would crash.
  • Percona Agent will now show a warning when being installed on an unsupported platform.
  • Query fingerprint is no longer replacing numbers in words.
  • If a SELECT query contained USE, it was abbreviated as USE query instead of SELECT in the fingerprint list.
  • Percona Agent didn’t log any errors when Query Analytics was used with the Performance Schema.
  • Metrics Monitoring didn’t detect MySQL restart if MySQL was started after the agent.
  • Percona Agent will not start if unrecognized command option is specified. Previously it would ignored the unrecognized options and start.
