Alertmanager IRC Relay
Alertmanager IRC Relay is a bot relaying Prometheus alerts to IRC. Alerts are received from Prometheus using Webhooks and are relayed to an IRC channel.
Configuring and running the bot
To configure and run the bot you need to create a YAML configuration file and pass it to the service. Running the service without a configuration will use the default test values and connect to a default IRC channel, which you probably do not want to do.
Example configuration:
# Start the HTTP server receiving alerts from Prometheus Webhook binding to
# this host/port.
#
http_host: localhost
http_port: 8000
# Connect to this IRC host/port.
#
# Note: SSL is enabled by default, use "irc_use_ssl: no" to disable.
irc_host: irc.example.com
irc_port: 7000
# Use this IRC nickname.
irc_nickname: myalertbot
# Password used to identify with NickServ
irc_nickname_password: mynickserv_key
# Use this IRC real name
irc_realname: myrealname
# Optionally pre-join certain channels.
#
# Note: If an alert is sent to a non # pre-joined channel the bot will join
# that channel anyway before sending the message. Of course this cannot work
# with password-protected channels.
irc_channels:
- name: "#mychannel"
- name: "#myprivatechannel"
password: myprivatechannel_key
# Define how IRC messages should be sent.
#
# Send only one message when webhook data is received.
# Note: By default a message is sent for each alert in the webhook data.
msg_once_per_alert_group: no
#
# Use PRIVMSG instead of NOTICE (default) to send messages.
# Note: Sending PRIVMSG from bots is bad practice, do not enable this unless
# necessary (e.g. unless NOTICEs would weaken your channel moderation policies)
use_privmsg: yes
# Define how IRC messages should be formatted.
#
# The formatting is based on golang's text/template .
msg_template: "Alert {{ .Labels.alertname }} on {{ .Labels.instance }} is {{ .Status }}"
# Note: When sending only one message per alert group the default
# msg_template is set to
# "Alert {{ .GroupLabels.alertname }} for {{ .GroupLabels.job }} is {{ .Status }}"
Running the bot (assuming GOPATH* and *PATH are properly setup for go):
$ go install github.com/google/alertmanager-irc-relay
$ alertmanager-irc-relay --config /path/to/your/config/file
Prometheus configuration
Prometheus can be configured following the official Webhooks
documentation. The url
must specify the IRC channel name
that alerts should be sent to:
send_resolved: false
url: http://localhost:8000/mychannel
