Zabbix
Extend visibility over hosts, problems and inventory without standing up a parallel server. Zabbix approach
Zabbix, Grafana and other systems
Tools
Observability integrations and utilities. Each piece is documented with its scope: which systems it works on and what it is for.
Talk about what is there. Distinguish an approach from a feature ready to use.
Grafana
Connect dashboards and alerts with the rest of the telemetry, rather than duplicating Grafana. Grafana approach
Other systems
Prometheus, Loki, OpenTelemetry and custom connectors when they add real correlation, not collection for its own sake.
How a tool is documented
Each piece has a name, scope, compatible systems and, where it applies, a licence. Anything not on this list is not assumed to exist.
