juju metrics reporting can be extremely slow

[Junien F]

Hi,

We just had a load spike on our controller running 2.2.4.
I tried to get metrics from juju (using the introspection proxy from axw), and it took 21 minutes for me to get a reply.

I'm sure that we can do better, even when under high load.

Thanks

I think to be useful, we need to be able to return interesting metrics even if things are under load. If we have some metrics that need DB access, then we should optionally skip them. Better to lose those metrics than lose visibility on the entire system.
