[mrtg] Master.cfg file issue

If you are using Routers2.cgi (which is implied by your use of Routers.cgi*Ignore:yes in the file), then that means you are using RRDTool mode - and if so, then the PNG/HTML files will never be updated as they are only created on demand by the CGI frontend.

Alternatively, if you are using native mode, then the HTML/PNG will be created, but not necessarily where you are expecting.  I suggest you put a WorkDir: directive in the master.cfg at the beginning and look for the files in there.  If your separate component cfg files contain WorkDir directives then they should all be the same (use Directory[] if you want to relocate them under this) and you may find that the other cfg files are being processed but their HTML and PNG are ending up in a different directory

Subject: [mrtg] Master.cfg file issue

Dear All,

I am running mrtg v2.16.2 on Ubuntu 9.04 server. I have installed the system and configured several devices with individual .cfg files and everything is working fine except some system/CPU loading is high.

For this I noted from the archives that creating a master.cfg file can improve system performance. I created the file as follows:
Forks: 30
RunAsDaemon: no
Router.cgi*Ignore: yes
Include: /etc/mrtg/sw203.cfg
Include: /etc/mrtg/sw204.cfg
 ..... etc,

However, I noticed that only the image/html files for the last device is updated - the rest are not. Strangely when I move any file to the bottom of the list in the master.cfg file the graphs are ONLY that device is updated.

Please can someone assist.
