I modified the package some weeks ago, The new version includes a check for temperature of each unit in a stack. I have uploaded the package to Check_MK Exchange site lately. It should become available after the verifitcation soon,
I have just uploaded a new package onto Check_MK Exchange. The package contains 2 checks for DELL N1500, N2000 and N3000 series switches. They check CPU utilization and RAM usage using SNMP requests. The checks have been created under 1.2.6 version of Check_MK and support this version.
After a verification by Check_MK staff the package can be downloaded from Check_MK Exchange web site.
