Hello!
Fyi, I just added 2 new panels to the the Elasticsearch Grafana
dashboard [1] (located at the bottom).
1) Nodes with < 25% disk free
The idea is to be able to catch cluster imbalanced earlier. There is
filter on the the data to show only nodes with < 25% disk free. At the
moment there are no nodes satisfying the criteria, so that graph is
empty. You can play with it by increasing the threshold...
2) Request rate (nginx)
This is mostly the same data as the QPS graphs we already have, but at
a lower level. I like having different measurements of similar things,
so that when things are not as expected, we might have a chance to
understand why. For example, this show ~ 500 request / second in
equiad, which are probably the Translate extension, and the index
updates (I need to check).
Let me know if you have other ideas of things that make sense...
