Re: Mysterious Sawtooth Graphs

Just to add to the other confirmations...
We've noticed this behaviour too (also using fping) after moving to 4.3.0.0 beta2 (clean install). We don't have very many hosts at the moment, but most of our hosts are multi-homed. The monitoring server has a separate network link for each VLAN/network, so no routing is involved for each connection test.
We thought the problem may be one or two faulty nic's on the monitoring server, but we get the 'sawtooth' behaviour with some systems but not others within the same VLAN/network.
So far we haven't found a solution though.

Hi I use Hobbit to monitor about 700 systems. I get some mysterious looking graphs with the CONN test and also the bbgen test itself. It looks like two overlayed sawtooth curves. Any idea why the graphs look so weird? I cannot believe these are the real response times. Here are two demo pics:
