If Kibana is not displaying metric or log information as expected, you can use journalctl to investigate the collectd and fluentd log files as follows:
- If only metrics information is missing, check the collectd log files.
- If only log information is missing, check the fluentd log files.
If both metrics and logs information are missing, check both log files.
To investigate collectd log files:
journalctl -u collectd
# journalctl -u collectdCopy to Clipboard Copied! Toggle word wrap Toggle overflow To investigate fluentd log files:
journalctl -u fluentd
# journalctl -u fluentdCopy to Clipboard Copied! Toggle word wrap Toggle overflow
To learn about the other journalctl options refer to the man page.
