My experience with Nagios

[Stanley Hopcroft]

Dear Sir,

I am writing to thank you for your letter and comment on the problem 
with embedded Perl Nagios (ePN).

Unfortunately I can't comment on the other matters.

If you use ePN, you probably should consider using --perl-caching also

I think this is the characteristic problem of ePN with Netsaint, Nag 
1.0, Nag 1.1 _and_ a threaded Perl such as you have (the thread support 
is OS specific: while all contemporary Perls provide a thread API it 
depends on whether the OS provides that facility. You are lucky enough 
to have one)

AFAIK, the necessary surgery was committed to the CVS (in the 1.x 
branch) in the last 3-6 months.

You should be able to get the modified files from the CVS

I think this would be done by selecting the Nagios-1.x-bugfix branch and 
then checking out the files

 nagios.c
 checks.c
 utils.c

or simply get the last branch of everything.

The modified files mainly have new function prototypes to accomodate the 
changes in the Perl API.

HTH.
