SNMP Linux Meminfo shows < 10 % available of 4 GB

groot
Hi all,

I have been running Sophos for half a year at home now and is generally happy with it. For the last month I have used prtg to monitor my network and devices. The meminfo sensor show me some weird values, all though I have 2x2 GB sticks in my box and it show 26% of 3.8 GB in use. Prtg reports that I have less than 10 percent available, and I cannot figure out how this works.

I will attach some pictures from my sensor if that is for any help. I thought the problem was fixed in the last update as you can see in the first picture, but now its down again.

Any suggestions is greatly appreciated.

Br,
Jonas

    What does WebAdmin show?  Is PTRG using the Sophos MIB?


    WebAdmin shows 28 % usage. PRTG uses SNMP. If thats a version of MIB, then yes.
