- KUSAMA is WILD!
- Grafana is a feature-rich metrics dashboard and graph editor
- Loki is the logging engine.
- Promtail sends logs to Loki
Distributor ID: Debian Description: Debian GNU/Linux 10 (buster) Release: 10 Codename: buster
If you already running Grafana just add Loki as a Data Source and install the Promtail agent on the KUSAMA/PolkaDOT Host 'Step 3'.
Grafana dashboard can be installed from https://grafana.com/grafana/dashboards/14899
- Logs are obtained by the scrapping job "journal" from the systemd-journal,
- The relabel_configs will provide you with a simple "unit" & "hostname" labels where you can separate multi-nodes by hostname
- as a unique value. Most of the logs are dropped since this monitoring is focused only on the PolkaDOT default logs level="info"
- but you can always drop more if you detect some.. by adding a match stage to the pipeline with a selector unit
- '{job="systemd-journal", unit="<UNIT.NAME>"}'
- match:
selector: '{job="systemd-journal", unit="init.scope"}'
action: drop
drop_counter_reason: promtail_logs
- Logging... well regex ".*", shall explain everything.
- Grafana Dashboard is quite simple as it looks, more like the host terminal with some extra visual statistics,
- don't forget the "{{hostname}}" the label is quite helpful on multi-node setups.
- Query limit configuration in the setting by default is 1000 if you want to adjust it, go do it!
- Labels set at the queries and then they are transformed to fields, filtered by names to suite the graphs needs.
=: exactly equal
!=: not equal
=~: regex matches
!~: regex does not match
