Re: restart program

[Martin Pala]

Hi,

this could be relatively easy to support - the event engine currently 
has for historic reasons hardcoded handling for several events:

/* Initialize general event handlers */
addeventaction(&(current)->action_DATA,ACTION_ALERT,ACTION_ALERT);
addeventaction(&(current)->action_EXEC,ACTION_ALERT,ACTION_ALERT);
addeventaction(&(current)->action_INVALID,ACTION_RESTART,ACTION_ALERT);
addeventaction(&(current)->action_NONEXIST,ACTION_RESTART,ACTION_ALERT);
addeventaction(&(current)->action_TIMEOUT,ACTION_UNMONITOR,ACTION_ALERT);


We can add the support for default action override ... i'll look on it 
when i'll have some spare time. The syntax can look like:


 check process apache ...
   if failed existence then exec "/path/to/script"
