Cause
The collectd service is failing to start due to systemd rate limiting.
Resolution
As a workaround, disable the rate limiting:
- Connect to a Plesk server via SSH.
- Add the following setting to the
/lib/systemd/system/sw-collectd.service
file:[Unit]
StartLimitIntervalSec=0 -
Apply the changes:
# systemctl daemon-reload
- Start sw-collectd service:
# systemctl start sw-collectd
- Go to Tools & Settings > Services Management > and start Resource Controller (Cgroups)
