Nagios Support Forum

Hi,

i wondered, why a plugin (which ran error-free through mini_epn) produced
ePN-errors. What i found out is, environment variables which are made from
custom macros are not visible by the embedded perl interpreter as they would
be if the plugin was started as a separate process.
I added a patch which adds set_all_macro_environment_vars(TRUE/FALSE); to
the code after use_epn=TRUE, but i'm not sure wether i put the function
calls to the right places. (At least at my test installation it's working)
Can you have a look at it?

Gerhard
