BigIP version 10 and logs to remote syslog server

Hi Guys,

 

I have a bigip 3600 version 10 running. I configure the below command to send syslog to a remote serfer, yet I am not geting the logs on the syslog server. Checking the traffic on the network shows that the bigip is not sending syslog traffic.

 

modify /sys syslog remote-servers add { SIEM { host 10.2.160.34 remote-port 514 }}

 

  • Was there a solution found to this? I have a very similar problem, I'm running tcpdump on all interfaces (in both bash and TMSH) but I'm finding that the LTM isn't sending out any syslog messages. I've even tried the echo test. I've gone over the routing differences between TMM and mgmt interfaces and everything looks ok, I'm stumped :S

      Yes mate, followed that as well. Got stuck at the final step:

       

      Using the tcpdump utility to verify that syslog traffic is sent by the BIG-IP system

       

      When manually generating a syslog message, nothing gets sent out to any configured syslog servers. Thought I'd ask the question to see if anyone else has had a similar problem before getting in touch with tech support.

    Justkennie - the command looks fine. Can you confirm it's correct when you run: list /sys syslog all-properties? Can you ping the syslog server from the BIG-IP?

     

    What about if you run tcpdump on the BIG-IP, does this show syslog traffic going out? I wonder if it's going out over a route you're not expecting? i.e. over a TMM interface rather than Management route? Do a filter on either interface 0.0 (TMM) or eth0 (management).

     

    Hope this helps,
