RE: [hobbit] ping test is too slow

["White, Bruce" <bewhite (at) fellowes.com>]

My experience with "hobbitping", is that it is just slower.  You are
better off downloading and installing "fping".   Once you do this, you
will need to rebuild hobbit and select fping in the build process.   The
"hobbitping"  tools was a nice idea, but never was fully developed.

Subject: [hobbit] ping test is too slow




Hi

for some time I am having problems with out ping test of hobbit. It runs
longer that the time intervall. Is it possible to speed up the test? I
don't want to make the intervall longer.
I am using the hobbitping. I tried doubling --max_pps from 50 to 100
with no effect.

Most of the time the DNS-lookup eats up 20 seconds, but sometimes it is
near zero! Why that? Most of my monitored system have a testip tag, so
should not do any DNS lookup at all. But some WLAN accesspoints which
are configured for using DHCP does not have the testip tag.

In the manpage of hobbitping I read something about a runtime of 18
seconds for 1000 clients. Why it is so slow on my machine? It's a fast
machine, Opteron with 1GBit network interface.

Here ist the output of bbtest:
