Russell,
You can try this tutorial [1] where in step 6 it's provide an init script. This tutorial is for CentOS 6, so you must work it out for Suse (if there is anything different).
Also, you can try my init scripts, which are also for CentOS 6. [2] for master and [3] for slaves. For CentOS, they must exist in /etc/init.d/, have proper permission for execution and me enabled by "chkconfig smokeping on" command.

Look for /etc/init.d/smokeping
The file (or possibly /etc/init.d/smokepingd) may already be on your system.
You may have to change the variable for the path to smokeping or it's config file near the top of the script.
Enable it using `chkconfig --add smokeping`

Subject: [smokeping-users] smokeping startup script installation + remocular question
Hello all,
I would like to make smokeping start automatically when the server reboots (I intend to do this for master and slaves as well).
I am using mostly OpenSuSE 12.3 (and some 12.2). Some are 64 bit other at 32.
On a previous message to the list about something else (mainly), I got the answer that a solution exists somewhere in the archives.
I will search the whole archive content if necessary but can any of you direct me to something more specific if possible?
I don?t want to appear lazy but quite a lot of content (over 140 files if I am correct).
If no one can offer anything specific I will start from the top (2013 and below..)
One more question.
I recently read some messages about remocular and the integration with smokeping. Please explain what is the benefit of such an integration? Please forgive me if the answer is obvious to some of you, it?s not to me, that is why I am asking.
Thanks again and keep up the good work everyone, nice to see such a well-organized and inspired community.
Special thanks to Tobi and Nico for a great tool.

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,

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,

There isn't any way, other than restructuring the RRD.
I've heard there are some tools that will help port data from one RRD
to another with different row setups - but doing so is a fairly
complicated process.
IMO, the value of keeping the old RRD's around is usually not enough
to justify reworking the data. But everyone's needs and wants are
different - so suit yourself.
But you either have to modify the RRD's and port the data, or delete
the old RRD's and let SP create new RRD's with the new row paramaters.
[On a side note - how much data does 20 pings produce, vs 5? IMO, the
additional load is rather small, and might not be worth messing with -
which would solve your historical data problem too.]

Bummer. I guess I'll need to learn the hacking process on the data, so I can
manipulate "pings=", and still keep the historical data. Because I can dump it
to XML via rrdtool(1), I'll see what I can put together.

Currently, I'm using: "curl -4 --head http://%host%/" on 35 sites, sendings 20
pings every 300 seconds. Interestingly enough, since midnight, I have ~9300
unique rquests in my /var/log/apache2/access.log file from curl(1). 20 hours,
9300 pings, thats 7.75 pings per minute, which seems higher than the 4 per
minute it should be.
At any event, I am also monitoring 5 Tor .onion sites to watch Tor latencies
with "curl -4 --head --socks5-host localhost:9050". Because the latencies are
so horrible, it seems that doing 20 pings every 300 seconds is causing the
other curl(1) PIDs to block until they finish. I say this, because I have gaps
in all of my graphs using the Smokeping::probes::Curl probe. I'm guessing these
gaps are a result of hitting the Tor sites so hard. I should probably back off
to 10 per 300 seconds, and see where that takes me, but then I lose all my Tor
historical data (unless I can hack the RRD files).
Thoughts?
