Change timeout alerts from CRITICAL to WARNING

[Nolan Martin]

Well, in my environment, I would attribute the timeouts to latency in
our network connections to the offending devices.  The server I run
Nagios on is fairly robust, and is not the issue.  I only receive the
timeouts for remote sites that see off and on latency.  

Certainly, in these cases, I also need to look at increasing the
timeout threshold, but I still would like to see the timeouts appear as
warnings, and not critical alerts.

Does anyone have a guess as to the source of the problem?

i have this from time to time as well but have been attributing it to
processor overload and am (or at was) expecting this problem to
disappear
once i get a new box.

anyone have thoughts?

Okay... Unfortunately, I am still not seeing the desired results... 
Here are the steps I have done.  Perhaps someone can identify
something
I have left out.  

* In a separate directory (to isolate my test modifications), I
downloaded and expanded the latest Nagios plugins.
* Ran the configure: ./configure --prefix=/usr/local/nagios
--with-nagios-user=nagios --with-nagios-group=nagios 
--with-cgiurl=/nagios/cgi-bin 
* Modified the check_ping.c file, lines 119 to 122 (see original
e-mail
posting below).
* Did a make all
* Copied the compiled executable to libexec
* Stopped and restarted Nagios, waiting for a timeout.  Timeout still
shows critical
* Posted to group and received recommendation to change the utils.c
* Went back to same directory
* Modified utils.c, lines 122 to 124 (as described by Nathan)
* Ran make all again
* Copied the new compiled executable check_ping plugin to libexec
* Stopped and restarted Nagios, waiting for a timeout.  Timeout still
shows critical

Thoughts or suggestions?  Thanks in advance.

If I remember correctly I believe I had to modify utils.c (line
122/124)
and change CRITICAL to WARNING and recompile the plugins....

When I did this I had compiled all plugins "stock" and then modified
and
recompiled so I had a modified version of check_by_ssh which was the
one
specific plugin I wanted only warnings for timeouts from.  

I think I ran strings on the binary plugin and found that modifying
the
.c for the plugin alone was not returning desired results 8-)

Best of luck,

Nathan
