sending nsca checks

[Stanley Hopcroft]

Dear Sir,

In the docco,

 'Integration with other software'
 'SNMP traps'

you will find a complete worked example of using send_ncsa to send 
passive service check results to a manager Nag.

Only if you like re-inventing the wheel.

This is the distributed monitoring scenario described in 

http://nagios.sourceforge.net/docs/1_0/distributed.html

You have 'local' Nags that check the hosts and services each is 
responsible for.

Each local Nag submits the results of its checks to the central - 
display Nag - with NCSA as described in that document.

This is the guts of the doing distributed monitoring: each local Nag 
has these (from the docco)

'Key configuration changes: 

     Only those services and hosts which are being monitored directly by 
the distributed server are defined in the object configuration file. 

     The distributed server has its enable_notifications directive set 
to 0. This will prevent any notifications from being sent out by the 
server. 

     The distributed server is configured to obsess over services. 

     The distributed server has an ocsp command defined (as described 
below).
'

The ocsp command is the bit that uses send_ncsa to submit the service 
check result to the central Nag for it to display.

You may say you don't want all this extra gunk - why go to the trouble 
of installing multiple Nags to send a few check results ?

You do. If you don't you will have to do all the things Nag does for you

1 Schedule the services - cron ??

2 Manage retries - add a layer to the check ??

3 Make the checks NCSA aware ???

4 Log the results  (Cron will do it, won't it ?)

Yours sincerely.

Europe is the less, as well as if a promontory were, as well as if a

me, because I am involved in mankind; and therefore never send to know
for whom the bell tolls; it tolls for thee...'
