What it means#
The disk under an agent’s home folder is running out of space. A full disk stops integrations from writing files and makes the agent’s collector lose telemetry it keeps while the hub is away.
What raises it#
The agent is online and the disk under its home folder has less than a fifth of its space free. It becomes an error below a tenth. The Health page shows the same reading. The problem needs the hub’s metric store, which every installation has unless it was set up without one.
What to check#
See each agent’s server, with its memory, CPU and disk:
$ weikio platform healthOn the agent’s host, see what uses the space:
$ df -h
$ du -sh /opt/weikio/*How to fix it#
Free disk space on the agent’s host or grow the disk. Integrations that write their own log files or keep files in their run folder are common causes, and so are old Docker images, which docker image prune removes.
