PRTG SOAP sensor, memory full but no warning




I have 2 vmware 5.5 ESXi with vCenter. I have vmware soap sensor for vcenter and getting all vm information

but, on some VM I have memory consumption 100% but its green, no warning or alert!

actually, it is using all memory, some use 90, or 80% memory, but sensor shows 100% and its green.

I should manualy set trigger on each sensor for memory? or there is some bug or other misconfiguration?

I am using latest PRTG, its a demo yet

memory sensor vcenter vmware

you are right, we decided to not set a default warning-limit for memory-usages as this heavily depends on your infrastructure.
In your case (2 hosts with a vCenter-Server) a limit of 50 % may be useful as you may not be able to takeover all running virtual machines to the second host in case of a crash or a scheduled maintenance as there is too less memory available.
In a setup with 3 or 4 hosts this limit may be 66% or 75%.

Kind regards

I thought I have written this yesterday bot no show-up

thanks for your reply

So, I have to go through each VM and set memory treshhold. but the problem is, that it will then send notification,

therefore, I need to see progress, e.g. on 50% it would go warning, and on 80% it goes red.

How this can be configured that it would show warning but no notifications, and on red it would do defined alarm action

This can be done with Error- and Warning-Limits in the Channel Settings of your sensor. They will cause the sensor to change its state if a certain value is reached.
