Add detailed information (pod restarts, resourses, env)

[feym78]

Hello.
Just tried this software, it looks nice, but it would be great to get some additional detalization:

1. with prometheus plugin it is not possible to chose timeline for metrics. there is only last 10 minutes displayed and looks like it is hardcoded in plugin, it would be cool to have a control for this like 10 min. 30 min, 1h and etc or even custom range (like grafana does)
2. there is no information about resource requests and limits, I saw several issues about this but still no feature yet
   for example Getting real time mertrics on Pod level for CPU/Memory requests and Limits? #1380 Pods: Add resource metrics to the list view #1
   It would be useful to see requests and limits at least in text and very useful also in graphical chart from prometheus plugin
3. it also be useful to see exit code if pod was restarted, not just restarts count, also would be useful to see exact time of last restart
4. there is env variables in pod details, but there is no values of these variables, it would be cool to get these values in pod description (except the ones mapped to secrets, it should be masked and not be accessible if token does not have permissions to get secrets), other software like Lens have this feature to show env values.
   upd 26.04
5. extra useful feature - to have some switch for parsing json formatted logs in pods

Fully agree and support especially points 1-3. Having those things present would make headlamp the go to tool for all things cluster related (on our side of things). As off now, we still have to jiggle with various tools to get all info needed in some cases.

@feym78 , @SquupS , I think those make a lot of sense. I will open issues for them so we get to them.
About point 3, I thought we were displaying the exit code. Maybe we only have this in the container?

@joaquimrocha Hi! Thanks for your reply.

Just checked windows desktop version - in containers section of pod's details there is only resatart count, no time or restart reason available.
Can't check it with in-cluster installation right now, but I think it's the same.

Same for in-cluster deployment. Not available there

@joaquimrocha Hi
I see that in last version there is already exit codes for restarted pods - great job, thanks headlamp team.
Also I see mention about json parsing in other opened issue, it's good to be heard.

For 1 point I created separated issue in plugins repo - headlamp-k8s/plugins#82

Can you please give some updates on points 2 and 4?
I find it very useful for a team to see actual pod limits to get understanding of given resources for their apps.
For 4 point I have some update: I noticed that if env variables in pod entered directly, then is shows in headlamp, but if it is mapped from configmap, then it doesn't. Is it a bug? If variable mapped to a secret, then its value omitted as expected (shows secrets field name?).
Thanks.
