SL1 PowerFlow powerflowcontrol (pfctl) Command-line Utility Release Notes, version 2.7.8

The SL1 PowerFlow powerflowcontrol (pfctl) command-line utility version 2.7.8 addressed a number of issues in the utility, including a complete update to the collect_pf_logs action, which is now called logcollect. This version of the utility is included with the PowerFlow Platform version 2.7.0 release.

For more information about the commands you can run using this utility, see Using the powerflowcontrol (pfctl) Command-line Utility.

Issues Addressed

The following issues were addressed in this release:

  • For the powerflowcontrol (pfctl) command-line utility, renamed the existing collect_pf_logs action to logcollect and updated the entire functionality of the action. For more information, see the logcollect topic in the Using the powerflowcontrol (pfctl) Command-line Utility chapter in the SL1 PowerFlow Platform manual. (Case: 00317293)
  • Added the pfctl node actions check_redis_maxmemory and fix_redis_maxmemory to verify the MAXMEMORY variable in the docker-compose.yml file. Before these updates, the PowerFlow Redis service expected a value of MAXMEMORY to be passed using Docker environment variables, but the override templates in the pfctl utility supplied maxmemory instead. The templates have been updated, and the new check_redis_maxmemory action determines if the Redis service requires an update to the environment variable, while the fix_redis_maxmemory action applies that change. The user will need to delete and recreate the Redis service after the fix action runs. In addition, the PowerFlow Redis image was updated to accept either MAXMEMORY or maxmemory as an environment variable. (Case: 00385354)
  • Addressed an issue where the pfctl utility did not properly calculate Linux memory availability when running the pfctl healthcheck action. (Case: 00321182)
