Hi,

I am working on some monitoring and have an idea were I could trigger a process or SNMP Event to alert someone of an issue. Has this ever been achieved by a Lavastorm customer before?
We use 4.1.8 Server - soon to update to 4.5.2 (or 4.5.3)

We use Linux and could install SNMPTRAP on the machine, if its possible to trigger a linux command.

Thanks in advance.

Xathras,

Have you considered using a Python node to execute a system command with the "os" module? You should be able to use os.system(" <command> ").

In truth, os.system has been somewhat replaced by the "subprocess" module. Its just the quick system call module I'm used to using. Take a look here:

http://docs.python.org/library/subpr...ule-subprocess.

Does this look like it would do what you need?

Hi Timon,

thanks for the information. It possible, as always to get a working example of this. e.g. a sleep command.

The attached node uses Python's sleep() function directly, without having to execute a unix command.
sleep.brn

Hi,

I'm looking for something that will do it on a linux machine. I used the sleep command as an example. But in reality I wanted to trigger a script.

Wayne,

Using the subprocess module in python you can make a call like this:

import subprocess
>>> subprocess.call(['./test.sh'])
0

Obviously this is done from the python prompt in the relative directory. But just extend the example to an absolute path to wherever a script is, and run the call in a python node. Does this help?
