Logging Origin-ID Problem

I am attempting to get my syslog messages to contain my hostname.  Below is my current config as well as a copy of the logging in the router.  Can someone explain what I am doing wrong?  I have also included my version of IOS in case that is a factor.

 

#sh run | i logg

logging buffered 51200 debugging

logging trap debugging

logging origin-id string MAS-RTR-01

logging facility local5

logging source-interface FastEthernet0/0.1

logging 192.168.x.x

Are you using event manager to gather the syslog info?

Yes I am forwarding all logging to logging event manager in solarwinds.  That's one of the reasons why I want have it resolve either the hostname or the string that I put in so that when the email alerts are sent they don't contain just the IP but the name of the router as well.  I have tried logging origin-id hostname previously and that also didn't work.  See below.

 

#sh run | i logging
logging buffered 51200 debugging
logging trap debugging
logging origin-id hostname
logging facility local5
logging source-interface FastEthernet0/0.1
logging 192.168.*.*

This was pulled just now from logging after changing the config to hostname and performing copy run start.

Try this...

logging origin-id hostname

 

 

Mike

have you tried

 

logging origin-id ip

 

HQ(config)#logging origin
HQ(config)#logging origin-id ?
     hostname     Use origin hostname as ID
     ip                 Use origin IP address as ID
     ipv6             Use origin IPv6 address as ID
    string            Define a unique text string as ID
<cr>

HQ(config)#logging origin-id ip ?
<cr>

HQ(config)#logging origin-id ip

I have not tried that yet.  However the logging event manager is already correlating the events from the source interface IP.  I just didn't understand why the logs on my router dont contain the hostname or string that I input.  What is causing it not to add that to the logs? I believe that if the logging was correct on the router I would be receiving the proper information in LEM.

I did see a bunch of Bugs that relate to this but since you are on EOL code it is harder to check stuff. I figured maybe if you set the IP and see if that works, then remove the command and retry the hostname command may it will kick it in the butt and work.

I'll give it a shot and post the results

Also maybe it could be how Solarwinds is taking the syslog information and it is just not using the hostname. Maybe contact solarwinds and ask them, there could be a setting that you can toggle.

This is what I am getting after setting the origin-id to ip

It's like the origin-id command isn't working at all.

My guess is a bug or something possibly with SolarWinds and how it receives the info. Do you have other Cisco gear that is newer where you could try it on that?

 

Mike

So I tried on a more current router.  This is one of our new routers on the network and the same model I will be upgrading all my older ones too.  see below

Try removing this line...

logging source-interface GigabitEthernet0/0/0.1

 

and then re-add it and try.

just in case someone has the same problem... - this could be the reason...

 

the origin-id is prepend to syslog messages sent to REMOTE hosts, so it will never show up on a console or monitor session.

from the Usage Guidlines:

[...]

The origin identifier is added to the beginning of all system logging (syslog) messages sent to remote hosts. The identifier can be the hostname, the IP address, the IPv6 address, or any text that you specify. The origin identifier is not added to messages sent to local destinations (the console, monitor, or buffer).

[...]

https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/esm/command/esm-cr-book/esm-cr-a1.html#wp3523355547

 

also on the syslog-server side, there is the possibility, that this information is cut-off after the message has been processed (parsed and filtered)
