[NV-L] SNMP Logging - Oddity

["Davis, Donald" <donald.davis@firstcitizens.com>]

While we are on the subject of SNMP oddities.

This is NOT a NetView problem, but, I thought All on AIX would be interested in this one.

I discovered this one when I rebooted my NetView server for the DST "TZ" environment variable change needed for this weekend.

I am running on AIX 5.2-ML06 and am not able to apply all the patches to AIX required for DST.

 

I had turned SNMP logging on at one time to try to diagnose a problem with the following settings :

logging                file=/trace/snmpd.log         enabled

logging                size=0                          level=3

When I was finished, I simply changed enabled to disabled, mistakenly thinking this would turn logging off.

logging                file=/trace/snmpd.log         disabled

logging                size=0                          level=3

 

Changing enabled to disabled stops writing the data to the file but does NOT stop logging.

I rebooted the server with a terminal (Cyclades Terminal Server) connected to tty0.

When the server came up to the Login: prompt I discovered that all of the SNMP traps being received by NetView were being spewed to the console port.  It took me a while to figure out what was happening. I blindly typed stopsrc -s snmpd and the spewing stopped. When I restarted SNMP the spewing started again. To stop the incoming traps from being written to the console, logging must be commented out completely like this.

 

#logging                file=/trace/snmpd.log         enabled

#logging                size=0                          level=3

Hope this helps someone prevent a little grief. 

I was in panic mode for a few minutes.

 

Regards.
