`vmalert` is a component of Victoria Metrics. It handles alerting and
recording rules, periodically executing queries and dispatching alerts
or writing aggregated data back to the TSDB.
The *victoria-metrics* role deploys a single-server instance of the
Victoria Metrics time series database server. It installs the selected
version by downloading the binary release from Github and copying it to
`/usr/local/sbin` on the managed node. Scrape configuration is optional
and can be specified with the `scrape_configs` variable.
