Docker compose environment for VictoriaMetrics
To spin-up VictoriaMetrics cluster, vmagent, vmalert, Alertmanager and Grafana run the following command:
docker-compose up
For single version check docker compose in master branch.
VictoriaMetrics
VictoriaMetrics cluster in this environment consists of
vminsert, vmstorage and vmselect components. Only vmselect
has exposed port :8481 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
vmalert evaluates alerting rules (alerts.yml) to track VictoriaMetrics
health state. It is connected with AlertManager for firing alerts,
and with VictoriaMetrics for executing queries and storing alert's state.
alertmanager
AlertManager accepts notifications from vmalert and fires alerts.
All notifications are blackholed according to alertmanager.yml config.
