Ping in Metronome...

Hi,
We have started to use Metronome as one of the tools to profile the service and narrow down bottle necks experinced by end-users. The metronome measures and displays the ping response time to the jazz repository server. We see that the ping time reported from Metronome differ much from the results from a regular OS ping machine-to-machine i.e. 200%-300%(470ms vs 167 and 82 vs 39). So the question is, what do the Metronome ping do? Is it an application to application ping? Does it call a I-am-alive web service on the Jazz server? Or what does it do and how does it differ corresponding to a regular OS ping?

Regards,
Fredrik

My understanding is that the OS ping is an ICMP ping which is fairly low level while the ping used by metronome is a http based ping with a certain amount of payload. In essence, it does call an "I-am-alive" service on the jazz server.

The numbers could be a bit different than an os level ping as we are actually calling into the web app and returning a jazz ping packet. So it's an app-to-app custom ping and not an OS level ping.
