Some extra OID's you can use for load measurement, memory usage and more
1 min CPU load average: 1.3.6.1.4.1.9.2.1.57.0 (5min is already in Lansweeper)
5 min memory used: 1.3.6.1.4.1.9.9.48.1.1.1.5.1
5 min memory free: 1.3.6.1.4.1.9.9.48.1.1.1.6.1
Load details: 1.3.6.1.4.1.351.140.1.2.13.1.1 (1.3.6.1.4.1.351.140.1.2.13.1.1.1 - 1.3.6.1.4.1.351.140.1.2.13.1.1.43)
These contain load numbers for verity of things on switch like interface bandwidth, bandwidth for CBR, VBR, ABR, UBR.
I was looking for temperature OIDs, but haven't found ones that work yet. Does anyone else have some?
