Troubleshooting

No data in Grafana I

  • Q: I don’t see any data!

  • A: Most probably, your system time is wrong or deviates from the time of the system accessing Grafana from. For example, you won’t see any data if the server time is in the future.

Tip

So, either enable the NTP feature of systemd:

timedatectl set-ntp true

or install chrony:

apt install chrony

or implement any other valid equivalent to keep the system time sound.

No data in Grafana II

  • Q: I still don’t see any data!

  • A: Try to increase the log level by adding --debug-foobar command line options to /etc/default/kotori and get back to us, stacktrace or GTFO. See /opt/kotori/bin/kotori --help for available options.

Example /etc/default/kotori:

KOTORI_OPTS="--debug-mqtt --debug-influx"
