amtool - Man Page

Show help.

View and search through current alerts.

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.

-i,  --inhibited

Show inhibited alerts

-s,  --silenced

Show silenced alerts

-a,  --active

Show active alerts

-u,  --unprocessed

Show unprocessed alerts

-r,  --receiver=RECEIVER

Show alerts matching receiver (Supports regex syntax)

Add a new alert.

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.

--generator-url=GENERATOR-URL

Set the URL of the source that generated the alert

--start=START

Set when the alert should start. RFC3339 format 2006-01-02T15:04:05-07:00

--end=END

Set when the alert should should end. RFC3339 format 2006-01-02T15:04:05-07:00

--annotation=ANNOTATION

Set an annotation to be included with the alert

Add a new alertmanager silence

This statement will add a silence that matches alerts with the alertname=foo and node=bar label value pairs set.

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.

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.

-a, --author=AUTHOR

Username for CreatedBy field

-d, --duration="1h"

Duration of silence

--start=START

Set when the silence should start. RFC3339 format 2006-01-02T15:04:05-07:00

--end=END

Set when the silence should end (overwrites duration). RFC3339 format 2006-01-02T15:04:05-07:00

-c, --comment=COMMENT

A comment to help describe the silence

expire an alertmanager silence

Import alertmanager silences from JSON file or stdin

This command can be used to bulk import silences from a JSON file created by query command. For example:

amtool silence query -o json foo > foo.json

amtool silence import foo.json

JSON data can also come from stdin if no param is specified.

-f,  --force

Force adding new silences even if it already exists

-w,  --worker=8

Number of concurrent workers to use for import

Query Alertmanager silences.

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 silence query alertname=foo node=bar

This query will match all silences with the alertname=foo and node=bar label value pairs set.

amtool silence 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 silence 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.

In addition to filtering by silence labels, one can also query for silences that are due to expire soon with the "--within" parameter. In the event that you want to preemptively act upon expiring silences by either fixing them or extending them. For example:

amtool silence query --within 8h

returns all the silences due to expire within the next 8 hours. This syntax can also be combined with the label based filtering above for more flexibility.

The "--expired" parameter returns only expired silences. Used in combination with "--within=TIME", amtool returns the silences that expired within the preceding duration.

amtool silence query --within 2h --expired

returns all silences that expired within the preceding 2 hours.

--expired

Show expired silences instead of active

-q,  --quiet

Only show silence ids

--created-by=CREATED-BY

Show silences that belong to this creator

--id=ID

Get a single silence by its ID

--within=WITHIN

Show silences that will expire or have expired within a duration

Update silences

-q, --quiet

Only show silence ids

-d, --duration=DURATION

Duration of silence

--start=START

Set when the silence should start. RFC3339 format 2006-01-02T15:04:05-07:00

--end=END

Set when the silence should end (overwrites duration). RFC3339 format 2006-01-02T15:04:05-07:00

-c, --comment=COMMENT

Validate alertmanager config files

Will validate the syntax and schema for alertmanager config file and associated templates. Non existing templates will not trigger errors.

View cluster status and peers.

View current config.

The amount of output is controlled by the output selection flag: - Simple: Print just the running config - Extended: Print the running config as well as uptime and all version info - Json: Print entire config object as json

Prints alert routing tree

Will print whole routing tree in form of ASCII tree view.

Routing is loaded from a local configuration file or a running Alertmanager configuration. Specifying --config.file takes precedence over --alertmanager.url.

Example:

amtool config routes [show] --config.file=doc/examples/simple.yml

Test alert routing

Will return receiver names which the alert with given labels resolves to. If the labelset resolves to multiple receivers, they are printed out in order as defined in the routing tree.

Routing is loaded from a local configuration file or a running Alertmanager configuration. Specifying --config.file takes precedence over --alertmanager.url.

Example:

amtool config routes test --config.file=doc/examples/simple.yml --verify.receivers=team-DB-pager service=database

--verify.receivers=VERIFY.RECEIVERS

Checks if specified receivers matches resolved receivers. The command fails if the labelset does not route to the specified receivers.

--tree

Prints out matching routes tree.

Render a given definition in a template file to standard output.

--template.glob=TEMPLATE.GLOB

Glob of paths that will be expanded and used for rendering.

--template.text=TEMPLATE.TEXT

The template that will be rendered.

--template.type=TEMPLATE.TYPE

The type of the template. Can be either text (default) or html.

--template.data=TEMPLATE.DATA

Full path to a file which contains the data of the alert(-s) with which the --template.text will be rendered. Must be in JSON. File must be formatted according to the following layout: https://pkg.go.dev/github.com/prometheus/alertmanager/template#Data. If none has been specified then a predefined, simple alert will be used for rendering.
