Customizing Prometheus AlertManager notifications in Slack

[Abraham Dhanyaraj]

Hi ,

I have few Win servers (Like Build, DB, App etc) where WMI is installed and configured, and able to read Metrics(based on rules like Disk Space >90) on my Prometheus dashboard.

Setup a Altermanager on the same box and I m writing Metrics (Diskspace >90) details to my Slack Channel.

route: group_by: [cluster] # If an alert isn't caught by a route, send it slack. receiver: slack routes: # Send severity=slack alerts to slack. - match: severity: critical receiver: slack receivers: - name: slack slack_configs: - api_url: 'https://hooks.slack.com/services/Token' channel: '#alerts'

And the output of Slack notification is - Actual

Is there a way where I can ready Machine Name - along with differentiating it with Tag Name - like Build , Db etc ?

I want notifcation to be more readable like below , (I got it from some blog) could you please suggest please ?

Expected 

Any thoughts on how to edit my AlertsManager.YML ?

Thanks,

I m able to acheive it. 

route:

group_by: [cluster]

# If an alert isn't caught by a route, send it slack.

receiver: slack_general

routes:

# Send severity=slack alerts to slack.

- match:

severity: critical

receiver: slack_general

receivers:

- name: slack_general

slack_configs:

- api_url: 'https://hooks.slack.com/services/Token'

channel: '#alerts'
