The credential test fails due to time out as per the error message "++: failed: SNMP request timed out."
====================================================
The first thing to do is to increase the timeout in the SNMP credential and retry. See http://discovery.bmc.com/confluence/display/83/Configuring+SNMP+credentials. If a timeout of 100 seconds is not enough, change the snmp version used in the credential and retry.
If this still does not work:
- check with "top" that the ADDM CPU is not saturated
- check that snmpwalk can access the device, Send the whole snmpwalk result
>> date > result.txt 2>&1; /usr/tideway/snmp++/bin/snmpBulk -C -v2 >> result.txt 2>&1; date >> result.txt 2>&1
For versions older than ADDM 9, use "date > result.txt 2>&1; snmpbulkwalk -v2c -c >> result.txt 2>&1; date >> result.txt 2>&"
This will capture all the error messages and the execution time. Note that
- check the health of the snmp device itself. Any problem of resources?
- check the network health. You may execute snmpwalk from different places on the network to check if this changes anything.
