vmalert

For sending alerting notifications vmalert* relies on Alertmanager configured via -notifier.url flag. Recording rules results are persisted via remote write protocol and require -remoteWrite.url to be configured. Vmalert is heavily inspired by Prometheus implementation and aims to be compatible with its syntax.

A single-node or cluster version of VictoriaMetrics are capable of proxying requests to vmalert via -vmalert.proxyURL command-line flag. Use this feature for the following cases:

• for proxying requests from Grafana Alerting UI;

• for accessing vmalerts UI through VictoriaMetrics Web interface.

• Integration with VictoriaMetrics TSDB;

• VictoriaMetrics MetricsQL support and expressions validation;

• Prometheus alerting rules definition format support;

• Integration with Alertmanager starting from Alertmanager v0.16.0-alpha;

• Keeps the alerts state on restarts;

• Graphite datasource can be used for alerting and recording rules. See these docs;

• Recording and Alerting rules backfilling (aka replay). See these docs;

• Lightweight and without extra dependencies.

• Supports reusable templates for annotations;

• Load of recording and alerting rules from local filesystem, URL, GCS and S3;

• Detect alerting rules which don't match any series.
