Remote monitoring fails due to limited options on server's "df" command.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Attempt to log into Linux-based system which uses BusyBox

What is the expected output? What do you see instead?

Expect statistics.  Instead, receive error because "-l" parameter 
is used on "df" command but "-l" is not always an available option.
-l is not available on busybox version of df.

What version of the product are you using? On what operating system?

1.0.2

Please provide any additional information below.

Recommend more graceful error handling where some calls can succeed even if one 
call fails (such as df).  Additionally, recommend allowing modification of 
command line calls through advanced
options so we can work around errors such as this.

The -l options does not appear to be doing anything for me.  I will remove it 
from my next build.

See if the attached executable jar runs in your environment.  If so I will post 
it in downloads.

Thanks

now it fails because -a is not a valid option.  On my version of busybox, the 
only available options are:

        -P      POSIX output format
        -k      1024-byte blocks (default)
        -m      1M-byte blocks
        -h      Human readable (e.g. 1K 243M 2G)

What does your output look like when you run:

uname -a; df -hP

from the BusyBox command line?

I was looking at the BusyBox website and making the remote-linux-monitor work 
for it might be a little further outside the box then I want to go.  I think 
the most logical approach would be to fork the software.  If you know Java or 
you know someone who does, I could certainly point them in the right direction 
to tweak the software.

Thanks

I do know Java.  I am a senior Java developer.  I might be interested in 
assisting with this if I can find time.

There are 4 classes

SystemInfo
ProcessInfo
FileSystemInfo
ResourceInfo

each class does the following:

1) issue the Linux commands.
2) retrieve the output
3) parse the response
4) assign the parsed tokens to a value class.

I believe all you will need to do is tweak the static member variable "COMMAND" 
and the parsing methods.

I do have a few code changes I was going to check-in tonight. If you would like 
you are certainly welcome to join the project, otherwise as you know you are 
certainly welcome to the code.

Thanks
Dave
