Hi,

Ok. run "svn up", then "./discovery.php -u" then "./discovery.php -h all -m mempools"

Then try creating your memory alerts again. "Physical memory" should now be useful for what you want. It now returns the amount of memory used excluding shared/cached. Just like the "free" command does.

Thanks,
adam.

Thanks for the reply Adam. I wonder how other monitoring systems (Cacti, prtg etc) do it? Or whether they can indeed do it at all.

Is there anything we can do to help on implementing this one?

Many thanks

I keep meaning to do something about this. It's because of the way memory is reported that our current collection doesn't really have an entity that can be sensibly alerted on.

I need to create another memory pool on Unix hosts which is calculated from the others, as we do with the "average" processor.

I keep forgetting to  work out the best wat to implement it, though.

We have about 20 Ubuntu hosts and 10 OSX hosts being monitored, all reporting their memory in a very literal way. Is the best way really to change how they report rather than how Observium interprets?

Many thanks for the fast reply by the way

You need to fix that in SNMPd, Observium is just reporting what it's being fed.

Hi,

Loving Observium in general but the only issue I'm having is that for all our Unix-like hosts the free memory is reported too literally to be useful.

The cached memory pool is included in the "used memory" count, causing almost all our hosts to appear as having less than 5% free physical memory.

Is there a way to get free memory not including the cached memory pool?

Currently the alert checker I'm using is flagging all our hosts as "out of memory"

Many thanks in advance
