Nagios Support Forum

I am using a free SNMP software and experiencing SET issues. the free program is based on standard RFCs and is a webserver version. I also have Nagios core installed. if i use the SNMP software to enter a MIB II Sysname, it will not maintain that description anymore, but it used to. In looking at the pre-requisites for Nagios, is this impacting my software?
thanks

By default, Nagios Core checks poll devices using SNMP and doesn't set values on the remote device using SNMP.
Now there could be a 3rd party plugin that was installed and configured on you system that is setting that value. You would have to look at the configurations and see if that is true.
