No graph displaying


14-03-2006 10:09:20

Hi all,
I've just installed netmrg on my linux station (FC4, with php5...), I followed the tutorial, I also check the forum but I've found nothing to solve my problem...

I do have change the netmrg.xml file with the right Database setup and the right rrdtool path ... but still have a broken image when clicking to display a graph ..
(I've also another rrdtool tool called cacti on my linux station and it all works fine).

Thanks for answer ...

I just added a page to the manual to help you determine why your graphs are not rendering http//

Please let us know if this doesn't help you resolve your problem.

Hey, Thanks for the answer ...

Here is what i get with debug -->

So, I did what is written in the Debug_graph_rendering page and i get this error

[b9ec3d3d33b]ERROR opening '/usr/local/var/lib/netmrg/rrd/mon_19.rrd' No such file or directory[/b9ec3d3d33b]

Indeed there is only zero.rdd in this folder.

--------------------> EDIT
I've got something else actually, after [b9ec3d3d33b]# ./netmrg-gatherer -sm[/b9ec3d3d33b]

NetMRG starting.
Creating Lockfile.
Initializing SNMP library.
Initializing RRDTOOL pipe.
MySQL Connection Failure. (Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2))
Critical Master database connection failed.
Closed RRDTOOL pipe.
Cleaned up SNMP.

Any advice would be great, thanks.

Can I change the path to mysql.sock or something ?

You can override the default MySQL socket. In the netmrg.xml file, change the "socket" statement under "database".
