VictoriaMetrics
VictoriaMetrics cluster in this environment consists of
vminsert, vmstorage and vmselect components. vmselect
has exposed port :8481, vminsert has exposed port :8480 and the rest of components are available
only inside of environment.
The communication scheme between components is the following:
- vmagent sends scraped metrics to vminsert;
- vminsert forwards data to vmstorage;
- vmselect is connected to vmstorage for querying data;
- grafana is configured with datasource pointing to vmselect;
- vmalert is configured to query vmselect and send alerts state and recording rules to vminsert;
- alertmanager is configured to receive notifications from vmalert.
vmagent
vmagent is used for scraping and pushing timeseries to
VictoriaMetrics instance. It accepts Prometheus-compatible
configuration prometheus.yml with listed targets for scraping.
vmalert

health state. It is connected with AlertManager for firing alerts,

All notifications are blackholed according to alertmanager.yml config.
