The VUE logging service uses Logrotate to prevent the local storage of VUE log files from consuming excessive space on the VUE node:
- The active log file is rolled over (archived) when it reaches the default maximum of 10 MB and a new active log file is created.
- A maximum of five archive log files is maintained on each container.
- If disk usage exceeds 75%, the logging curator automatically reduces the number of log files, as needed, to a minimum of 0 archived and 1 active log files.
- Archives older than 30 days are deleted.
The VUE logging service also uses Curator to prevent the central log storage from consuming excessive space on the VPS#2 node. Curator is a third-party open source software that periodically checks the disk usage on VPS# 2 and executes a purge if usage exceeds predefined threshold. The default threshold configuration is as follows:
- Purge the log data older than 90 days regardless of available space.
