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>
This is an error from the rrdtool library. So I would suspect something dodgy with the graph-definition in hobbit-graphs.cfg, or the RRD file data is not as you would expect.
Could you show us the graph definition you use ?
See attached. Also attached all files you might require to recreate the mysql sensor.
Note that the graph works for one machine, but not for the other.
And the layout of the RRD-file - a command like
rrdtool info mysql.rrd |grep "type ="
Both files yield identical output: ds[mysqlht].type = "GAUGE" ds[mysqlhq].type = "GAUGE" ds[mysqlhs].type = "GAUGE"
-- Arie
should give us the necessary info about the datasets and their type.
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.
It shouldn't, and I know I have hostnames with dash'es in them. Haven't noticed any problems with graphs there, but I'll have a look.
