Hot links:
- Grafana cloud account dashboard: Manage API keys, members, payment, enable/disable data sources, etc.
- Grafana instance: Actual grafana site.
- Explore (query) data sources directly. Loads automatically labels.
- Use and manage Dashboards: prepared queries shown in panels - tiled graphs.
- Grafana cloud credentials onboarding process
We hired Grafana Cloud services. This provides us:
- Visualisation: Grafana instance
- Metrics: Prometheus data storage
- Logs: Loki server
- Customer support
This doesn't provide us:
- Metrics: Prometheus server
See Ansible playbook to provision a Prometheus instance
middle-person role: remote-read from many hosts → remote-write to single prometheus db - Logs: Promtail, logs collector agent
- Mixed logs/metrics dashboards:
currently Loki can only be visualized through Grafana explore. Since v6.4 logs can be visualized from Grafana.
