Thanks for the PR. Could you please:

• Move the change to packaging/examples/...? The files in examples/... are the released files which change only with a new release.
• Once you do that, can you please run make dashboard_install to lso copy the change into the Helm Chart?

Thanks.

I tried it in my environment and it looks great.

The only thing I was wondering about is whether there issome way to sort the table? Right now it seems to have no soerting and with every update of the dashabord the lines reorder, so it is hard to read sometimes and acts a bit disruptively as it keeps changing.

Sorted now by pod name:
