[smokeping-users] apache alias setup?

[Sipponen, Sami]

Hi,

I'm running Smokeping 2.3.6 on Debian Squeeze (Linux 2.6.26-2-686 on i686) and from time to time Smokeping stops measuring and starts drawing blank graph. This happens maybe once in a month and is that rarely that I'm not actually interested on the root cause. However I'd like to monitor when Smokeping stops measuring and restart the Smokeping daemon or maybe even restart the whole server.

I have automatical update script which uploads new configuration to Smokeping once every night and probably it will get Smokeping confused when the config is reloaded too many times. Usually the measuring stops when the update script has been run, but when I restart the Smokeping daemon or the whole server it starts working perfectly well. Smokeping startup messages:

So is there any readymade script that can look inside RRD's or some other way notice that Smokeping is dead even the daemon itself is up and running? (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...
