rrd2mysql gateway

[Stef Coene]

Hi,

I really need to get the rrd counters in a mysql database.  I was able to hack 
hobbitd/do_rrd.c: on each update a perl script is executed with the 
parameters updparams[1], hostname, updparams[3] and updparams[4].  This is 
not working because for every update, the perl script is executed and this 
fills up the memory of my server.

I also tried to replace the perl script with a shell script that puts all the 
data in a named pipe.  But this blocks the hobbit rrd module.

So, can anyone help with more C knowledge then I have?
I was thinking about a non-blocking named pipe in hobbitd/do_rrd.c.  Or maybe 
an extra communication channel like hobbit uses internal.
The best solution would be adding mysql support to hobbit. but I also need to 
do some conversion of the data and I prefer to do this in perl.

Thanx in advance,


Stef
