Functionality Added or Changed

• Agent: The libxml2 library bundled library bundled in the Windows distribution of MySQL Cluster Manager has been upgraded to version 2.14.5. (Bug #38198545)

• Client: MySQL Cluster Manager now uses the third-party library GLib version 2.84.3. The new GLib version is included in the MySQL Cluster Manager distribution archive. (Bug #38198580)

• OperationBegin and OperationEnd events are now logged to the event log for the agent connected to the client. The output looks similar to the following:

  1754993119061902;1;create site --hosts=100.103.24.29,100.103.24.180 mysite
  1754993119384512;100;10129;{30e31bae 1 0}

  (Bug #38229518)

• The advisor mechanism was extended with the following:

  • A new CLI command, list advice.

  • Cluster DataMemory advice

  • mcmd disk usage advice.

  • mcmd RAM usage advice. An event was also added to the eventlog for both the high and normalized cases.

  • mcmd CPU usage advice. An event was also added to the eventlog for both the high and normalized cases.

  • mcmd agent missing or disabled TLS configuration advice.

  • mcmd agent default credentials advice. This is only visible through the list advice command.

  • Threshold checking for the advice, so it does not fire again until the average drops below the threshold.

Bugs Fixed

• Agent: The mcmd event log was not reloaded on mcmd startup. As of this release, if an event log exists, it is reloaded. (Bug #38222837)

• Under certain circumstances, the event log could write incorrect timestamps to file. (Bug #38224675)

• The backup advisor only triggered once if no backup was performed. As of this release, it triggers each time the defined period is reached. (Bug #38210378)
