SNMP is not working for few services

[tthomas]

Hello,

I am trying to put a solaris machine under monitoring.

OS version - SunOS 5.10 Generic_144489-06 i86pc i386 i86pc

SNMP is working fine on the server and it is collecting data for few services , but few other services it is not working.

For example it is collecting data for swap memory usage but physical memory usage is giving error

Unknown storage : Physical memory : ERROR

Could you please help me to resolve this issue.

Regards

Are you using Sun's SNMP implementation or did you install net-snmp?

Hi ssax,

I am using Sun's SNMP implementation.

Can you run a snmpwalk or your Solaris server and post the output back here?

Code: Select all

snmpwalk <IP Address> -v 2c -c <Community String>

Could you also post how you are running the check command that is failing for you?

[vnc786]

if you are using check_snmp plugin you can use verbose (-v) and see at what OID it is trying and as suggested by tgriep try snmpwalk and match the OID.

You can grep the output of the snmpwalk to limit (filter) the results. An example:

Code: Select all

snmpwalk x.x.x.x -v 2c -c <community> | grep -i memory
HOST-RESOURCES-MIB::hrMemorySize.0 = INTEGER: 4019552 KBytes
HOST-RESOURCES-MIB::hrStorageType.3 = OID: HOST-RESOURCES-TYPES::hrStorageVirtualMemory
HOST-RESOURCES-MIB::hrStorageType.10 = OID: HOST-RESOURCES-TYPES::hrStorageVirtualMemory
HOST-RESOURCES-MIB::hrStorageDescr.1 = STRING: Physical memory
HOST-RESOURCES-MIB::hrStorageDescr.3 = STRING: Virtual memory
HOST-RESOURCES-MIB::hrStorageDescr.6 = STRING: Memory buffers
HOST-RESOURCES-MIB::hrStorageDescr.7 = STRING: Cached memory

Hi

Please find the output below.

COMMAND: /usr/local/nagios/libexec/check_snmp_storage.pl -H HOSTNAME -C STRING -m 'Physical memory' -w 99 -c 100 -f -o 5000

~]# snmpwalk HOSTNAME -v 2c -c STRING| grep -i memory

Command output in verbose mode.

If you are trying to check the amount of memory or storage space?
If you are trying to check the memory of the server you should use the check_snmp_mem.pl plugin.

Hi

I tried with check_snmp_mem.pl plugin, but It is complaining about the format I used for the command. I am not sure what login credentials it is looking for other than community string.

Code: Select all

COMMAND: /usr/local/nagios/libexec/check_snmp_mem.pl -H HOSTNAME -C STRING -w 99 -c 100 -f
OUTPUT: 2 warnings and critical !
Usage: /usr/local/nagios/libexec/check_snmp_mem.pl [-v] -H  -C  [-2] | (-l login -x passwd [-X pass -L ,])  [-p ] 

We are getting unknown error for CPU load as well.

Code: Select all

COMMAND: /usr/local/nagios/libexec/check_snmp_load.pl -H HOSTNAME -C STRING -w 99 -c 100 -T stand -f
OUTPUT: Can't find CPU usage information : UNKNOWN
