Hi,
Initially I filed my problem as a bug over here: https://sourceforge.net/tracker/?func=detail&aid=3116811&group_id=128058&ati...
but now I am not sure it is a bug, so posting it here for more lively discussion:
I created a custom mysql parameters check that shows graphs on one server, but not on the other. hobbitgraph.sh (hobbitgraph.cgi?) kept sending following error instead of the actual image: <html><head><title>Invalid request</title></head> <body>Attempting to reuse 'mysqlht'</body></html>
If I request the same image for different server, same service - I get the image. If I copy the mysql.rrd file from the /var/lib/hobbit/rrd/atl-db01/mysql.rrd into the /var/lib/hobbit/rrd/pa04, then the image for pa04 shows graph for the atl-db01.
Could be that dash in name of that particular server was affecting the hobbitgraph.cgi somehow? I can attach the hobbitgraph.d/mysql.cfg and hobbitserver.d/mysql.cfg if that would help.
