Define channel or user mention per host

[nicolinux]

I'd like to be able to define a Slack channel name or Slack user for a host (or service) and when a notification is sent, to add @channel or @username so a mention is triggered in Slack.
This should alert the right people who are in charge of the specific host/service by mentioning them in the monitoring channel.

Do you have a pointer about the best way to implement it?

Thanks,
Stefan

Hi @nicolinux

You could make the notification scripts configurable by removing the channel (or user) assignment: https://github.com/jjethwa/icinga2-slack-notification/blob/master/slack-service-notification.sh#L5

Modify the NotificationCommand:

object NotificationCommand "slack-service-notification" {
  import "plugin-notification-command"

  command = [ SysconfDir + "/icinga2/scripts/slack-service-notification.sh" ]

  var slack_channel = "#alerts"
    if (notification.vars.slack_channel) {
       slack_channel = "$notification.vars.slack_channel$"
    }

  env = {
    "NOTIFICATIONTYPE" = "$notification.type$"
    "SERVICEDESC" = "$service.name$"
    "HOSTALIAS" = "$host.display_name$",
    "HOSTNAME" = "$host.name$",
    "HOSTADDRESS" = "$address$",
    "SERVICESTATE" = "$service.state$",
    "LONGDATETIME" = "$icinga.long_date_time$",
    "SERVICEOUTPUT" = "$service.output$",
    "NOTIFICATIONAUTHORNAME" = "$notification.author$",
    "NOTIFICATIONCOMMENT" = "$notification.comment$",
    "HOSTDISPLAYNAME" = "$host.display_name$",
    "SERVICEDISPLAYNAME" = "$service.display_name$",
    "SLACK_CHANNEL" = "$slack_channel$",
  }
}

then

apply Notification "slack" to Service {
  import "slack-service-notification"
  user_groups = [ "noc" ]
  interval = 5m
  var slack_channel = "#noc"
  assign where host.vars.sla == "24x7"
}

I didn't test this out fully, it's just off the top of my head, but it should get you close to what you want to accomplish. Let me know if I can help further 😄

Greetings,

I have been trying to implement your method to integrate ICINGA and SLACK. However, i m not seeing any notifications though to slack automatically going if an Event occurs in Icinga.

IF i run #icinga deamon -c

root@sony-VPCEH25EN:/etc/icinga2/conf.d# icinga2 daemon -C

warning/ApplyRule: Apply rule 'slack' (in /etc/icinga2/conf.d/notifications.conf: 29:1-29:37) for type 'Notification' does not match anywhere!
warning/ApplyRule: Apply rule 'slack' (in /etc/icinga2/conf.d/notifications.conf: 37:1-37:34) for type 'Notification' does not match anywhere!

Could you please help.

Thanks
Aravind

Hi @ananthaa-advisory

This is a different issue than the original poster brought up. Ideally this should be a new issue.

From the error, it looks like you're missing the slack-host-notification.conf or slack-service-notification.conf ?

[ananthaa-advisory]

Yeah. I'm a new user to Github as well. So commented on the post.

I have made lot of double checks and I didn't miss anything. I just copy and pasted whatever you have said. It looks to be a notifications issue Though.

Hi @ananthaa-advisory

Do you mind copy/pasting all of the related configs here? Something is missing 😢
