Nagios Support Forum

Hi
I'm using Nagios XI for monitoring my infrastructure, and once on host was a problem.

Using check_xi_service_snmp_linux_storage for monitor / disk, for ARG1 -C FreeBSDPublicSNMP --v2c -m "^/$" -w 80 -c 95 -f
and error: ERROR: Description/Type table : The message size exceeded the buffer maxMsgSize of 1472.

so, correct ARG1: -C FreeBSDPublicSNMP --v2c -m "^/$" -w 80 -c 95 -f -o 2000
run command: / : 76%used(27543MB/36454MB) (<80%) : OK | &apos;/&apos;=27543MB;29163;34631;0;36454

but, at nagios XI service status: octet lenght must be < 65535 and > 484

Why ?

Can you test the command from the CLI rather than the GUI and share it's output? There's likely escaping issues happening in the GUI.

I would also suggest reviewing your /etc/snmp/snmpd.conf file on the remote host to make sure the maxMsgSize isn't being set too low.

so, test the command from the CLI is good, like GUI
and

[root@maschine-test]# cat /etc/snmp/snmpd.conf | grep maxMsgSize
[root@maschine-test]#

Does applying the configuration via the Core Config Manager change anything?

Can you send over a system profile? From the Nagios XI GUI, you can gather a profile via Admin -> System Profile -> Download Profile.
