Nice! I like the addition of the type, not so sure about including the pod name. The pod name is ws|prebuild + instanceid and we already have the instance id in the third column and now we also have the type, so the pod name does not convey any new information.

@Furisto That's fair. And I'd expect that from workspace team engineers. But with engineers from other teams being on-call for these, they are not always aware of the mapping between a workspace type and instance. Even here it's non-obvious because Regular workspaces use ws while prebuilds do use the full prebuild.

For me personally, this would've saved me a bunch of time during on-call, and especially during the first time handling the alert as I wasn't directly aware of the mapping between ws type and pod.

As another data point, this came up during Week 31 on-call, (internal) thread here

I see. We should have a FAQ kind of document that explains these things. Until we have that I am fine with including the pod name. cc @kylos101 for awareness
