[PR] [CELEBORN-688] Add JVM metrics grafana template [incubator-celeborn]
onebox-li opened a new pull request, #1964:
URL: https://github.com/apache/incubator-celeborn/pull/1964
### What changes were proposed in this pull request?
Currently there is no JVM metrics grafana template, nor in grafana labs. For better use, it is necessary to add one.
According the change in #1939
This template uses two variables(instance, pool).
The layout is divided into 5 rows.
The panels with g1 look like below：
JVM Memory Pools row uses replicated panel mode which panels are automatically deplicated by `pool` variables.
### Why are the changes needed?
Ditto
### Does this PR introduce _any_ user-facing change?
Yes, this dashboard is based on changes in #1939
### How was this patch tested?

Yea, for me, I always check the whole cluster's status to see if the cluster is healthy.

> Can you provide a screanshot when it shows the whole cluster? Or it only support show one worker?
This template now just supports one instance. For JVM metrics, one panel often contains serveal metrics so that we can easily obtain information by comparing related metrics. The cluster perspective may make the diagram a mess. Users can customize the jvm metrics panel of the entire cluster they care about or use explore. But I will change the variable to be multi-selected later to make the template easier to use.

Hi, @AngersZhuuuu, I've supported selecting multi/all instances, snapshot like below, please take a look again if have time.

I have called a increase function on it. https://github.com/apache/incubator-celeborn/pull/1964/files#diff-68dcac07da1db4f5aa934eb21ef636d9fc903f02e85db78acb9f59988baaed0eR946

Re: [PR] [CELEBORN-688] Add JVM metrics grafana template [incubator-celeborn]

> How about G1? I remember when I use G1 in a test cluster, it was not same in origin code
You can find the example graphs with g1 in the top PR proposal. Different collectors only have different labels in the new jvm metrics. For pools metrics with different collectors, it can be generated dynamically by the benefit of grafana's replicate panels function(Repeat this panel for each value in the selected variable).

> I want to know if the metrics name will be different in different GC?
No, It will only change related metrics labels. For specific details, you can refer to https://github.com/apache/incubator-celeborn/pull/1939. When use ParNew + CMS, the JVM Memory Pools / GC rows look like below:
