haproxy-status3: Non-sense check

[10RUPTiV]

Hi,

The data gathering some haproxy csv is having some part that need to be excluded from the check!

The SERVERNAME " BACKEND " will always be /1.0 , that mean it will always generate a CRITICAL.

We spoke with Haproxy team (we have a business contract with them) and they told us, there's no way in the config to increase the /1.0 on for this one.

Maybe it should be remove from the "check" ?

I will have a look into it. 👍

It seems that you are referring to the Sessions column, and you get a CRIT, because 2 out of 1 possible sessions are used (which is weird).

I had a look at the plugin output in one of our datacenters. There, the output looks like this:

So in BACKEND, our HAproxy supports up to 300 connections. In this special case, we are running HAProxy version 2.4.17, and check plugin version 2022021602. What do you use on your side?

Markus,

We are using HAproxy EE 2.4r1 and the latest plugin...

But in our backend config, we have not set any limit... that's probably why we have a limit of "1"

Just did a little test and I can confirm that having no maxconn in the backend setting, equal "unlimited" until we reach the GLOBAL maxconn

Closing this issue. If this check warns about sessions, this is a HAProxy configuration issue. Unsetting or setting maxconn to appropriate values helps (as intended and expected).

This is the haproxy.conf related to my screenshot above (relevant parts only):
