Notify scripts informations

Hi,

I'm tring to merge keepalived notifications by using the notify_* features.

As of today, our keepalived servers are handling about:
   - ~360  Virtual Server Group
   - ~1700 Virtual IPs in IPVS
   - ~2800 Realservers associated to these VIPs
This setup can produce a lot of notifications depending of the realservers
activities.

What I'm trying to do is to reduce the number of emails received for realservers
states changes. I am using the notify_up and notify_down methods to store the
state changes informations for 5 minutes and then send these informations in a
single mail. At the end of this mail, you will find my configuration file and
the notify script both used for tests. The script is full of debug to see what
is actually passed by keepalived.

When I compare email notification content with accessible informations from
script, I see that some informations like check result are missing. I have not
seen any change from release 1.1.20 to 1.2.7 on this point but I could have miss
something.

Is there a way to access all informations visible in notifications emails using
the notify_* directives ?
