What happens if primary changes after re-election? #7

Closed svenmueller closed 8 years ago

Hi,

I'm just wondering what happens if a re-election happens and the primary changes. Is the metrics-reporter still capable of gathering metrics from the secondary node?

Thanks!

Yes, reporter will continue to work and send secondary's metrics. In fact it already happened a few times.

Ideally reporter should be able to detect primary changes and adopt itself. Secondary stats are not very useful (at least not as useful as primary's)

Thx! Yep, that's true. Actually it would be really nice if the reporter could send stats for all nodes in the cluster :)

Thx a lot for your work!
