Computer and IT knowledge - things to know
sample snmpwalk command to get out, some information from the vsa:
#default community string ist public
snmpwalk -v 2c -c public <vsa-ip-address> .1.3.6.1.4.1.9804.3.1.1.2.12.46.1.19
some interesting snmp mib variables can be found in the file "LEFTHAND-NETWORKS-NSM-CLUSTERING-MIB.mib", which can be found on the internet
for example:
clusModuleStorageStatus storage status of a module .1.3.6.1.4.1.9804.3.1.1.2.12.46.1.19
clusModuleRaidStatus RAID status of a module .1.3.6.1.4.1.9804.3.1.1.2.12.46.1.10
clusModuleName hostname of module .1.3.6.1.4.1.9804.3.1.1.2.12.46.1.4
.1.3.6.1.4.1.9804.3.1.1.2.12.46.1.2
>> have this knowledge, you can easily build a simple perl script that queries the information from the VSA and formats to "checkmk" format, so that it can be used as an "individual script":
