Creating alerts for marathon failure

1. Under Explore tab select Server -> Overview.
2. Choose Group by mesos.framework.name.
3. Click on the bell button next to marathon framework ( marathon [:8080] ) from the list. A new alert popup will appear.
4. Under Set the condition choose type as manual
5. For Alert when option Choose Entity is down.
6. Leave Where option unchecked.
7. Choose the minimum monitoring value as 1 min.
8. Specify the Name, Description and Severity of the alert.

While grouping with mesos.framework.name on sysdig, it lists marathon from work running on one of the masters ( marathon [:8080] ). But the ip showing in the list might change when marathon is restarted. In that case we need to create alert for new listing name also. For solving this issue, we need to create alert for each of the master nodes. In order to do that:

• Go to Alerts page and select the alert we have created from above steps. Click copy for creating a similar alert.
• Modify the master ip from the scope manually.
• Specify the ip of another master and create a new alert.
• Similarly create alert for each of the master nodes.
