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.
