Traffic Logs for Virtual IP

Hey all,

 

 

trying to find if we have a command to see the traffic logs on a VIP

 

I got a LTM running 9.4.5

 

 

i want to see the date and time of the traffic that hit a particular VIP

 

is this possible ?, right now i am able to see only the counters

 

 

Thanks in advance for helping

 

 

Cheers,

 

Roger

    Hi Roger,

     

     

    By default, LTM doesn't log details for every connection to a VIP. You could do this using an iRule, but it will have a performance cost. Here is an older logging iRule example:

    For 9.4.0+ you can use log -remote to send UDP syslog messages to a remote server. This should be more efficient than logging through syslog-ng. See the log wiki page and an article from Deb for details:

     

    http://devcentral.f5.com/wiki/default.aspx/iRules/log

     

    http://devcentral.f5.com/Default.aspx?tabid=63&articleType=ArticleView&articleId=190

     

     

    If you can upgrade to v10.1.x, you could use the high speed logging (HSL) options for an even more efficient option:

    9.4.x is going out of support soon, so it would be a good idea to upgrade to 10.2.x regardless. And as an added benefit, HSL should give a good performance improvement over the log command.
