Re: false alerts after upgrade

FYI, I stepped back to 1.30 and the problem has gone away.

Last week I upgraded Smokeping from 1.24 to 1.31. I'm now periodically
receiving false alerts that a host is down. The next polling interval
I'll receive the alert that host is back up. I'm only monitoring ~100
hosts at a 120 second interval. At this time only one is
non-responsive.
Any ideas about the problem?

thanks,
andy

transit time measurement tool needed

Hello,
we want to monitor packet transit time and packet loss rate. Packet round
trip time (RTT) and ping loss rate are not sufficient for us, because  we
don't see which direction causes variations in RTT and packet losses.

Does anyone know about tools do do this? I know about the problems with
accurate time synchronization, we have GPS time sync with accuracy better
than 100us available. It would be perfect to view the results with
smokeping.

Thanks,

Burkhard

I know several systems that measure one-way delay and loss.  As you
say, one-way delay requires synchronisation (one-way loss is easy
though).  Both require special software at both ends.

rude/crude - http://rude.sourceforge.net/

        Simple command-line tools to send and receive UDP packets.

        The sender generates packets with timestamps, according to
        either a rate/size, or a script with packet sizes and relative
        timestamps.

        The receiver generates a log file including sender timestamps
        (from the packets) and receiver timestamps, which you could
        then use to feed something like SmokePing.

        It shouldn't be too difficult to build a system based on this
        yourself.

RTT, latency and availability calculations

Hi,

writen a perl script to get RTT, jitter, availability and packet loss
from Smokeping RRDs. Anybody interested?

Cheers,
Bostjan
