Help with monitoring traffic - TS hits/second and origin server requests/second

[Manish Pandey <ma...@gmail.com>]

Hi Group,

I have configured TS as a reverse proxy, and would like to monitor the
following:

1. Number of hits/second, i.e., directly served by TS
2. Number of requests/second to origin server by TS
3. #1 and #2 in terms of MB/s

Any suggestions on hos this can be obtained?

Thanks,
Manish

Thanks -- that worked.  It would be nice to have stats like traffic
per client IP address of per domain. Any suggestions of what packages
to start off with for developing this?

If there are no takers on this, I will be glad to work on this.

Normally I'd look at something like (using traffic_line -r ...)

     proxy.process.http.incoming_requests
     proxy.process.http.outgoing_requests

and calculate a delta over time.

Also, I think

     proxy.node.user_agent_xacts_per_second

will show number of client transactions / second as well. Not sure if 
there's a similar stat for origin requests. Cache hit ratios are 
available in a multitude of ways, probably the easiest being:

     proxy.node.cache_hit_ratio
     proxy.node.bandwidth_hit_ratio

There are similar "stats" for bits (I'd refer to either 
proxy/mgmt2/RecordsConfig.cc, my bible, or the Admin guide HTML docs). 
But, for example

     proxy.node.client_throughput_out

should show "client" traffic.


Also, you can run "sudo traffic_shell", and run various "show" commands 
interactively, e.g.

% show:proxy-stats



We probably need a "Wiki" page with a list of the most useful stats. Any 
volunteers? ;)
