|
|
This command is used to add a new alert to Alertmanager.
|
|
|
|
To add a new alert with labels:
|
|
|
|
amtool alert add alertname=foo node=bar
|
|
|
|
If alertname is omitted and the first argument does not contain a '=' then it will
|
|
be assumed to be the value of the alertname pair.
|
|
|
|
amtool alert add foo node=bar
|
|
|
|
One or more annotations can be added using the --annotation flag:
|
|
|
|
amtool alert add foo node=bar \
|
|
--annotation=runbook='http://runbook.biz' \
|
|
--annotation=summary='summary of the alert' \
|
|
--annotation=description='description of the alert'
|
|
|
|
Additional flags such as --generator-url, --start, and --end are also supported.
