Changing pings count

I'm trying to get a good handle on the ping count for my installation when
using curl(1). I should keep it small, so as to not hit the destination website
too hard, but when adjusting it, smokeping gives an error about the different
number of data sources changing in the RRD, and refuses to show the graphs. It
says to remove the RRD file, and reload smokeping, but that also gives all
sorts of errors.

This guy has the exact same error:

    https://lists.oetiker.ch/pipermail/smokeping-users/2011-June/004338.html

The only way for me to fix this, is to remove the RRD file, reload smokeping,
add a new target, reload smokeping again, then pull up the new target in my
browser, and force a refresh. This seems to force an update on all the RRD
files, and fixes everything, but then I've lost my historical data.

How can I change the "pings = 20" to "pings = 5" in my configs, in a clean way?

Thanks,

NTP probe

Has there been any thought about putting an NTP probe together for
smokeping, or has any work already been done in this area? Just curious.

Thanks,

Re: Smoke Ping Stops Working

my guess is simply that the master node stops polling; try running it
in debug mode.

here's a startup script I use, runs as root but starts daemon off as
user smokeping:

OPTS="--debug-daemon --nodaemon"

cd /usr/local/smokeping
chgrp -R smokeping cache data var
chmod -R g+w cache data var

su - smokeping -s /bin/bash -c "cd /usr/local/smokeping ; bin/smokeping $OPTS"

comment out OPTS when running normally.

I don't know if it's related but if the slave is running in debug
mode, it stops working when the master is restarted; this on centos6.4
x64.

units for rtt_max

please can someone update the page
http://oss.oetiker.ch/smokeping/doc/smokeping_config.en.html

and specify what the units are for rtt_max, and whether it needs to be
an integer or fixed value?

it's possible to work it out through trial and error, but having it
stated specifically would be more useful.

thanks

partially solved problem with tcpping probe on centos6

Hello,
I am trying to use the tcpping probe with smokeping installed on centos6.

The first thing I had to fix was to put an explicit path in the
tcpping script to use /usr/bin/tcptraceroute, because centos stupidly
has a softlink at /bin/tcptraceroute to the standard system traceroute
binary!

I install smokeping into /usr/local/smokeping; the tcpping script is
in the bin directory.

If I run the master in debug mode, I see it is calling the plugin like this:

TCPPing: forks 5, timeout for each target 26
TCPPing: Executing /usr/local/smokeping/bin/tcpping -C -x 5 somehost 4949
TCPPing: Received: GLOB(0x24d0850)
TCPPing: somehost: got
Calling RRDs::update(/usr/local/smokeping/data/TCPPing/somehost.rrd
--template uptime:loss:median:ping1:ping2:ping3:ping4:ping5
1370260050:U:5:U:U:U:U:U:U)

However, if I execute the plugin at the command line, it works happily

# /usr/local/smokeping/bin/tcpping -C -x 5 somehost 4949
somehost : 0.391 0.269 0.301 0.281 0.315

I am running smokeping as the user/group smokeping; if I "su -
smokeping -s /bin/bash" and then try, tcptraceroute would complain
"Got root?"

The solution is to "chmod u+s /usr/bin/tcptraceroute".

I still see "TCPPing: Received: GLOB(0x24f12f8)", so I was wondering
if someone can suggest a way of fixing that?

I hope this helps someone as I spent quite a time tracking these two
problems down.

Paul
