Confusion around metrics

[neshmi]

I've been looking at the 'postfix_showq_message_size_bytes_count' metric. I would like to be able to monitor the queue depth for postfix, and this seems to be the most appropriate metric, however, I am not sure if I am grasping what it is trying to express.

It doesn't seem like there is any metric that will count individual messages (that would be a great metric to have), so how exactly should I be using this metric to understand the queue depth with postfix? I've seen a grafana dashboard using this exporter, but that graph doesn't really correspond with the messages we are processing.

Any insight here would be really welcome!

thanks!

I'd guess you are looking for postfix_smtp_status_total to see how many messages are on the queue?

That certainly sounds like a promising metric, but that isn't showing up for me. Is it possible I'm missing something in the configuration? Or is this a recently introduced metric?

So, what is postfix_showq_message_size_bytes_count actually expressing? I saw this issue: https://github.com/kumina/postfix_exporter/issues/15 but I'm still not entirely sure what this metric is expressing. Just want to make sure I'm understanding that.

Thanks!

I've installed the postifx_exporter on three systems (via a docker image and as binary) but I do not get this metric, to.

I don't have that metric either.

Any news on this? That metric is missin here as well ....
