# Slack notification script for Munin
|
|
# Mark Matienzo (@anarchivist)
|
|
#
|
|
# To use:
|
|
# 1) Create a new incoming webhook for Slack
|
|
# 2) Edit the configuration variables that start with "SLACK_" below
|
|
# 3) Add the following to your munin configuration:
|
|
#
|
|
# # -- Slack contact configuration
|
|
# contact.slack.command MUNIN_SERVICESTATE="${var:worst}" MUNIN_HOST="${var:host}" MUNIN_SERVICE="${var:graph_title}" MUNIN_GROUP=${var:group} MUNIN_IMAGE="http://munin.example.org/${var:group}/${var:host}/${var:plugin}-day.png" /usr/local/bin/notify_slack_munin
|
|
# contact.slack.always_send warning critical
|
|
# # note: This has to be on one line for munin to parse properly
|
|
# contact.slack.text ${if:cfields \u000A* CRITICALs:${loop<,>:cfields ${var:label} is ${var:value} (outside range [${var:crange}])${if:extinfo : ${var:extinfo}}}.}${if:wfields \u000A* WARNINGs:${loop<,>:wfields ${var:label} is ${var:value} (outside range [${var:wrange}])${if:extinfo : ${var:extinfo}}}.}${if:ufields \u000A* UNKNOWNs:${loop<,>:ufields ${var:label} is ${var:value}${if:extinfo : ${var:extinfo}}}.}${if:fofields \u000A* OKs:${loop<,>:fofields ${var:label} is ${var:value}${if:extinfo : ${var:extinfo}}}.}
