[Feature] Karma compact view

[hsolberg]

Hi!

Great job so far with Karma and all the features! We're trying to recreate an overview that we have in another monitoring solution called Zabbix (with a custom frontend for alerts). Rather than just adding support for Prometheus for ourselves I thought it be better to add it to Karma and check if anyone has a similar usecase. I've made some examples using mock-data below for how this works in our Zabbix solution, but first some info on the data being used here.

• host names used (this would translate to pod-name)
  • demo01, demo02, demo03, demo04, another-demo01, another-demo02, another-demo03, another-demo04
• triggers used (this would translate to alertname)
  • warning-test, average-test, high-test
• severity/priority-levels used
  • warning, average, high

Maintenance would translate to Silences in Alertmanager/kthxbye (this might not be that important to show for kubernetes, but might be useful when the targets are VMs or bare metal servers).

The color-scheme represents the severity-level, this might be harder to implement in Karma since this can be whatever the person puts in the alert-field, but maybe this could be optional and mapped using a config file?

This just shows that the maintenance window on the right side can be toggled on/off by pressing the "maintenance"-button in the top left corner.

When I click on the row with the grouped alerts there's a detailed list of all servers with the same alert/trigger. With the option to acknowledge the alert, this would not be relevant for Alertmanager as it's not the same logic, but here you could put the "Silence"-button instead. The pictures below are just for the two other alert names.
