[SOLVED]How to use the "Status Change Command" in Cacti settings

[eholz1]

Greetings Cacti users,lovers, and developers:
I want to create a file that has ONLY device IP, device Name, and device status = up or down

I have discovered what may be a very useful feature in Cacti - in settings/Alerting/Thold called "Status Change Command"
I created a small script that sends and email if something happens setting the path to the email script. As shown below:

If a device goes down or up - I get an email, but :
How can I create a script to access some of the variables listed in the rollover tip, like: <THOLD_HOSTNAME>,<THOLD_DESCRIPTION>,<THOLD_DOWNUP>, etc?

I can get the vars in the test.out file, is there a way to use env in a script to get
certain variables? ;ole THOLD_HOSTNAME. THOLD_DATE etc

Please advise,

Yes, this is primarily a shell scripting training issue. Depending on your language, you can reference the environment variables in your scripts...

bash, csh, zcsh, etc...

Variable name STUFF
Value is $STUFF

Perl

Variable name STUFF
Value is $ENV{'STUFF'}

PHP

Variable name STUFF
Value is getenv('STUFF')

It goes on and on for each of your preferred languages. Easy stuff actually. You'll figure it out.
