Issues with SNMP, HOST-RESOURCES-MIB::hrSystemUptime.0 = No more variables left in this MIB View

Posted: 2019/09/07 23:20:52

I have CentOS6.5 server, which is enabled SNMP, which is being monitored with Enigma NMS.

Enigma NMS monitors this box CPU, Ram, File System, etc.

Then suddenly I have noticed that for some unknown reason CPU data disappeared, the following OID:

hrProcessorLoad -

Has started giving me "No more variables left in this MIB View" output instead of proper result as below (From another identically configured CentOS6.5 server):

HOST-RESOURCES-MIB::hrProcessorLoad.196608 = INTEGER: 1
HOST-RESOURCES-MIB::hrProcessorLoad.196609 = INTEGER: 1
HOST-RESOURCES-MIB::hrProcessorLoad.196610 = INTEGER: 1
HOST-RESOURCES-MIB::hrProcessorLoad.196611 = INTEGER: 1
HOST-RESOURCES-MIB::hrProcessorLoad.196612 = INTEGER: 1
HOST-RESOURCES-MIB::hrProcessorLoad.196613 = INTEGER: 2
HOST-RESOURCES-MIB::hrProcessorLoad.196614 = INTEGER: 1
HOST-RESOURCES-MIB::hrProcessorLoad.196615 = INTEGER: 1


But all other OIDs in HOST-RESOURCES-MIB seemed OK.

I have tired to upgrade to 6.10, which went well, however the hrProcessorLoad was still giving me "No more variables left in this MIB View".

I have tried to un-install all net-snmp rpms as below:

# rpm -qa | grep snmp


rpm -e net-snmp-utils-5.5-60.el6
rpm -e net-snmp-5.5-60.el6
rm -e net-snmp-libs-5.5-60.el6


And I have reinstalled them back with yum, which went well.

However teh current situation is even worse as, if I do snmpwalk, all I get is is just a handful of lines as below, i.e. no interfaces data nothing.:

# /usr/bin/snmpwalk -r 2 -t 2 -v 2c -c 'public'

HOST-RESOURCES-MIB::hrSystemUptime.0 = No more variables left in this MIB View (It is past the end of the MIB tree)
[root@prod-server admin]#

This is where the snmpwalk output ends...

I would really appreciate if someone could point me to the right direction.

Re-installing the server is not an option as it is in production with database size of around 5Tb.

Thanking you in advance.

Hi again

Just forgot to mention that this started happening around the time I have enabled ESXI6 VM Host with SNMP and CentOS6.5 Server VM lives on this VM Host. No VMTools installed within this VM.

For me it does seem completely unrelated, but I may be wrong.

Kind regards and thank you.
