I want to set an alert on a graph in Grafana, but I am not able to set.

If the used value in graph exceeds above 27 TiB then it should create an alert.

Also, I want slack notification of grafana graph after every four or six hours. But I am not able to see any option for that. Can you please help me regarding this

  • Check the Axes tab --> X-Axis column: If you are calculating Total in the value part as you can see in the below

  • Then, change the avg() to sum() in the Condition:

    @Abhijeet Now you are calculating Sum() of metric B in last 5 minutes, Change it to 1hour, Something like this: WHEN sum() OF query(B,1h,now) IS ABOVE ... – Note that your dashboard time range (Last 1 hour), makes your graph's value. – – Sepehr roosta Jan 23 '19 at 06:06
  • What should be values for `If no data or all values are null` and `If execution error or timeout` –  Jan 23 '19 at 06:53
  • @Abhijeet These are for times when data is intrrupted or server is Disconnected. – Sepehr roosta Jan 23 '19 at 06:57

  • @Abhijeet Have you added `slack` in notification channels? – Sepehr roosta Jan 26 '19 at 09:46
  • Yes I have added `slack` notification channel. but grafana is not sending alerts only once it sent alert at beginning. –  Jan 27 '19 at 05:02
  • @Abhijeet In Grafana -> notification channels -> YOUR_SLACK_CHANNEL ; uncheck `send on all alerts` and `include image`, then try `Send Test` – Sepehr roosta Jan 27 '19 at 05:40
