If you dont know much about mibs and OIDs best option to start with is following command
Code:
snmpwalk -v 1 -c public localhost .

mind it output will be huge and messy but u will have everything. For best results redirect output to a file and then look for familiar values.
e.g.
Average load
Code:
snmpwalk -v 1 -c public localhost load
UCD-SNMP-MIB::laLoadFloat.1 = Opaque: Float: 15.886719
UCD-SNMP-MIB::laLoadFloat.2 = Opaque: Float: 15.601562
UCD-SNMP-MIB::laLoadFloat.3 = Opaque: Float: 15.335938

system uptime:
Code:
snmpwalk -v 1 -c public localhost sysuptime
DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (1862835767) 215 days, 14:32:37.67

you can compare these values while by cross checking with OS commands.
And Finally
Code:
snmpwalk -v 1 -c public localhost disk

.......
.....

Output was too long so i pasted only few lines. Now you can search for OIDs / MIBs and get what u want.
I call it learning while doing
:P

Linux Total Processes - Why monitor it?

Hi Guys, Monitoring 'Total Processes' on Linux servers has been always something you 'should' do. My question is - why? Is it relevant anymore? If you monitor memory and cpu params, you have a pretty good idea about what's going on. Is the number of processes really matter? Thanks (1 Reply)
