GTM with LTM Request Response Stats

Hi Jiri,

 

both GTM and LTM are using virtual servers to handle incoming requests.

 

In case of GTM you create a so called listener object which is showing up as a virtual server in LTM as well. Each incoming DNS query will show up in this virtual servers statistics. A connection will represent a request. If you are GTM expecting to return multiple resource records upon request (by default a single record is returned only) you want to poll the dns profile statistics instead. I assume the cached responses are contained in these stats but I would recommend to cross check.

 

For pure LTM virtual servers the http profile statistics will be relevant from my perspective. A client may use a keepalive connection to use an existing connection without outstanding responses for new requests. Thats why the connection counter of this type of virtual server tells very little about the number of handled requests. But these statistics are collected in the http profiles. In the bottomline you will get best statistics data from the dns and http statistics profiles in my opinion.

 

Thanks, Stephan
