New Features

Real-time Table Info

When using Query Analytics, you can get SHOW CREATE TABLE, SHOW INDEX, and SHOW TABLE STATUS for each table used by a query.

Local data spool limits

Percona Agent saves data locally in /usr/local/percona/percona-agent/data before sending it to PCT. This data is now limited to 1 hour, 10 MiB, and 100 files.

In previous versions, when Percona Agent worked offline for some time (for example, because of connection issues) this data either filled up disk space indefinitely, or caused a network burst after it came back online.

Bug Fixes

  • Resolved an issue when queries had first_seen attribute later than last_seen attribute.

  • Fixed crashing of Query Analytics with Performance Schema on null DIGEST.

  • Removed warnings like strconv.ParseFloat: parsing "ON": invalid syntax from the Percona Agent log.

    As of MySQL 5.6 and later versions, SHOW GLOBAL STATUS does not contain only number variables. This caused Percona Agent to flood the log with warning messages when a value of a variable could not be converted.

Other improvements

  • The diskv package was updated to avoid potential goroutine leaks.
