[smokeping-users] Monitoring smokeping

[Russell Dwarshuis]

There are plenty of free process monitor scripts out there but I don't 
have any experience with them.  A quick check of sourceforge yielded one 
in php: http://sourceforge.net/projects/phpdog/ but it's new so "use at 
your own risk".

Browse the others by going to 
http://sourceforge.net/softwaremap/trove_list.php?form_cat=253 (sys admin) 
then search results for process.

But, of coures, if smokeping is still running (just not updateing rrd's) 
than it won't help you.

Perhaps you could modify or write your own script to also check some .rrd 
files using rrdtool like so:

$ rrdtool last AnnArbor_Chicago.rrd
1243349909

Compare the output to the current unix epoch time and if it's too old then 
restart.  If you want a more thorough check you could run rrtool dump 
ping_localhost.rrd > /tmp/rrd.xml and look for sane values.

(all graps are showing "nodata_color" only) If there is no such script already made, any hints how to make one? I'm familiar with PHP, but Perl or Shell scripts are not my speciality, however I'm willing to try...
