Amtool has a simplified prometheus query syntax, but contains robust support for
bash variable expansions. The non-option section of arguments constructs a list
of "Matcher Groups" that will be used to filter your query. The following
examples will attempt to show this behaviour in action:
amtool alert query alertname=foo node=bar
This query will match all alerts with the alertname=foo and node=bar label
value pairs set.
amtool alert query foo node=bar
If alertname is omitted and the first argument does not contain a '=' or a
'=~' then it will be assumed to be the value of the alertname pair.
amtool alert query 'alertname=~foo.*'
As well as direct equality, regex matching is also supported. The '=~' syntax
(similar to prometheus) is used to represent a regex match. Regex matching
can be used in combination with a direct match.
Amtool supports several flags for filtering the returned alerts by state
(inhibited, silenced, active, unprocessed). If none of these flags is given,
only active alerts are returned.
