What is the difference between STATISTIC_BYTES_IN / STATISTIC_BYTES_OUT
and - STATISTIC_SERVER_SIDE_BYTES_IN / STATISTIC_SERVER_SIDE_BYTES_OUT
I need to monitor the total thr...
The stats STATISTIC_BYTES_IN/OUT are the byte counts on the external public facing side of the device. The STATISTIC_SERVER_SIDE_BYTES_IN/OUT are the byte counts that go through the internal private side of the device. These values may be different if you have a profile inserting headers or an iRule that is modifying content in some way. Let's say for instance that you want to insert the X-Forwarded-For header to your HTTP web servers. This isn't in the payload from the browser to the BIG-IP but it is counted in the bytes to the webserver (serverside).
As for which you choose, it's really up to you and your requirements. For most cases, using the external stats only is close enough.
Hope that helps...
