Nagios Support Forum

Hi all,

I am using Nagios Core 3.4.1 and have been having issues with alerts with status "Unknown" and the following description: "ERROR: Process name table: message size exceeded maximum buffer message size of 10000".
I have reviewed the alert settings and there are no errors in the names being monitored.
The alerts constantly change from "OK" to "UNKNOWN" status, this last status being the most common.

Could you help me to know how I can solve this problem?


Thanks in advance.

If the check is running the Windows SNMP plugin, have a look at how others fixed it:

Hello Gonmark,
Thanks for your reply.

Apparently I do not have access to see the information on the attached link.
I add an image.

Here's info from the link.

Open check_snmp_win.pl in a text editor.
vi /usr/local/nagios/libexec/check_snmp_win.pl
Find this line:
$session->max_msg_size(10000)
Set the value to something higher.

Hi Gonmark,

I appreciate and thank you very much for your help. I have done what you suggest but some alerts are fixed and others go from status ok to unknown

Is there anything else I could do?

Regards.

You might copy and paste the text of the new errors here, as well as what you did to reduce the problem.
