Most dell servers are capable of generating and sending SNMP TRAPS for system event such as component failure or status change. Traps are very useful in alerting as they are instant compared to the normal status polling done by any network management software. Moreover, traps are more granular as you can receive Traps for monitoring component such as temperature sensor or even temperature sensor for a single CPU.
To configure traps for dell servers in MSP CENTER PLUS software you need to do the following steps:
Add the DELL Server in mspcenter
Check if SNMP TRAPS is enabled in the Dell Server
Configure the dell server to forward traps to the MSP CENTER PROBE software (which resides in the same LAN as the dell server)
Check if TRAPS are being received by the probe
Check if TRAPS are being forwarded to the central
Convert UNSOLICITED TRAPS into ALARMS
Step1: Add the DELL Server into MSP Center
Go to the MSP CENTER Central Server UI and choose Network Monitoring->Admin-> AddDevice
Step2: Checking if SNMP TRAPS is enabled in the Dell Server
Go to the dell server and open the services panel. Start-> Run-> Services.msc Check if the services named SNMP TRAP and SNMP are running and in automatic mode.
Step 3: Forwarding TRAPS to mspcenter probe
Right click on SNMP Service and choose properties. This will open the properties panel. Choose TRAPS tab and set the SNMP Community and MSPCENTER PROBE IP. Note: Trap destination = your probe ip address.
Step 4. Checking if TRAPS are being received in PROBE
Now open the MSP Center Probe UI and go to admin-> SNMP TRAP PROCESSING Disable the following processors
ColdStart
ColdStart (v2c)
Now restart the DELL Server
Open probe UI and choose unsolicited traps from the top right corner
Check if you are able to see any traps being received from the DELL SERVER here
Step 5 : Check if traps are being forwarded to central
Open the MSPCENTER central server UI and go to Alarms-> Unsolicited Traps
You should be seeing the unsolicited traps from the DELL Server here ...
Step 6 : Converting Unsolicited TRAPS into ALARMS
To convert unsolicited traps into ALARMS you have to create whats called as TRAP PROCESSOR. You can create TRAP PROCESSOR in two ways
Choose an UNSOLICITED TRAP that is already created in the probe, and then make a rule to convert further such TRAPS into ALARMS
Load a DELL MIB and choose all traps implemented in the MIB and create rules so that any futher unsolicited trap gets converted into ALARMS automatically.
The difference between option 1 and option 2 is that option 1 can be done ONLY on the already created traps. You cant create a rule for a trap that has not happened yet. But option 2 is like creating a rule for future traps.
Option 1: Creating trap processor from already received unsolicited traps From the probe UI choose admin-> SNMP TRAP PROCESSOR -> Unsolicited Traps
Option 2: Load Traps from MIB From the probe UI choose admin-> SNMP TRAP PROCESSOR -> Load Traps From MIB
Now you have to find the DELL MIB ... if you dont have one, search and get it
download the MIB and put it under probe/mibs folder
click on the MIB name and choose the traps you want ...
Uploading ....
