Allon,

Without your MRTG config file it is hard to tell what is the cause of not displaying anything for a specific target. 
Have you checked the "MaxBytes[...]" value for the Max memory? If this figure is lower then the data polled by your script it will display only 0 in the graphs.
You can also check if you use the the "Gauge" option at the options[...] line.
If these values ar OK and still nothing shows in your graph please post the relevant part of your config file.

HTH,

Jan.

Subject: [mrtg] MRTG not processing data


Hi-

I've been using MRTG successfully now for a few applications.  However, I recently setup some scripts to grab the total memory and used memory of a Linux server.

In the config I have a local machine set and a remote machine, to the remote machine it executes the command over ssh.

On the remote machine it successfully gathers 3 statistics: Max Memory, Used Memory and Uptime, and displays correctly on the graph.

On the local machine it only displays Used memory, never graphing Max Memory.

I look at the .log file and it looks like this:

1091565601 526159872 519553024
1091565601 0 511143936 0 511143936
...

I have had the script output to a file the results it polls and it is indeed getting the 3 statistics.  Why is the local device failing?

Any insight would be really appreciated.

-Allon
