Actually, this is not just in Nagios; this is standard Unix escaping.
And it's not really 3 \. Rather, what is going on is that standard Unix
escaping is applied twice - first when parsing the config file, and
again when passing the arguments to the plugin.
In Unix, normally when you put a \ anywhere, it escapes the following
character. For instance, a \ before a space means the next character
isn't really a space, don't treat it as the end of the path. And a \
before a \ means the second backslash isn't really an escape character,
but rather I want a literal backslash. So in order to get a single \ in
the plugin, on the command line you need to escape it with another \.
You found that out when you ran check_nrpe2 from the command line.
Now when Nagios parses the config file, it uses the same escaping
mechanism. So when you simply put \\ into the config file, Nagios
interprets the first one as escape and the second one as escaped to
be literal - thus, you'd end up with a single \ in the command line.
But you wanted two \. So you need to tell Nagios to do the same thing
twice: - \\ in the command line - \ for the plugin to see.
And where you needed the plugin to actually see \\ (before the
localhost), you need to do the same thing yet again, for a total of
eight consecutive backslashes.

Of course, right after I sent that, I found a solution. It seems I can
use 3 \s to escape a \. My path in the service definition becomes:
localhost_definst_mp3mn_mp3_08_07streams
...and it works.
Is there a list of all the ways to escape special characters in Nagios?
The only reason I came up with the three \ escape sequence was because I
noticed that my localhost was being seen as \localhost in the error
message. I haven't found any mention of that sequence on google. :-/

Subject: Escape \ in nagios config files?
I want to check the disk space of a UNC path -
\\localhost\_definst_\mp3\mn_mp3_08_07\streams
From the command line, I can check it fine (using check_nrpe2) if I
escape each \ like this:
localhost\\_definst_\\mp3\\mn_mp3_08_07\\streams
But when I try to use configure Nagios to check it, it strips out all
the \ characters. I've tried single quotes, double quotes, and escaping
each \ - no luck. How can I tell Nagios about this path in a service
definition without it stripping out the special characters? Is there an
escape method I'm missing?
