Thanks for your feedback - that problem is the exact problem we are =
trying to brainstorm.
We have 1000+ hosts running vanilla NRPE installations and we would like =
to start upgrading them to allow for more output. We would like to have =
as non-intruding upgrade procedure as possible - no "big bangs" etc.
But apparently there is no way a sysadmin can upgrade a NRPE-client for =
itself without touching the Nagios server-config also (switch to a new =
check_nrpe for the host) at the same time.
I had hoped the allowed output size was implementation-specific (not =
enforced by design), but it seems we will have this problem every time =
we want to touch the output size.
I guess the first problem we face right now is to choose a buffer size =
that makes sense, and try to test it across our platforms (different =
versions of solaris/linux/freebsd mainly, but we have other nix'es as =
well) - there was a post mentioning there might be output limits =
regarding the pipe mechanisms in the os'es also. We need to choose the =
value that gives us the maximum output size while avoiding new related =
problems arising.
Anyway, this problem will probably get more attention once nagios 3 goes =
RTM - I know we are a bit early here.
Best regards,
Steffen
