Hi!
I'm doing my first Nagios plugin based on Nagios::Plugins and I noticed that it automatically supports --extra-opts.
So I did my first attempt with this feature as it seem to well fit my needs.
unfortunately I observed 2 strange behaviours:
-
I had an argument "msg|message" and this led to some weird parsing of the extra opts. My config file was like this:
[experiment]
percent=1
message=%d OK
The result was percent was undefined and msg was set to "--percent".
When I changed the argument to "message|msg", it worked. Now percent is set to 1 and message is set to '"%d OK"'.
And this leads to my second strange behaviour:
-
Every value, which contains spaces, is automatically quoted. So instead of having just
%d OK
I get
"%d OK"
. and I think this is a bug.
Update
Some code to play with:
use strict;
use warnings;
use Nagios::Plugin;
use Data::Dumper;
my $n=Nagios::Plugin->new(version=>1,usage=>"");
$n->add_arg("percent","",undef,0);
$n->add_arg("msg|message=s","",undef,0);
$n->getopts();
print Dumper $n->opts
Output is (shortened)
$VAR1 = bless( { :
:
'msg' => '--percent',
'verbose' => 0,
'usage' => undef,
'percent' => undef,
:
}, 'Nagios::Plugin::Getopt' );
Which is wrong. If you change "msg|message=s" to "message|msg=s" the output will be almost correct:
$VAR1 = bless( { :
:
'percent' => 1,
'version' => undef,
'message' => '"%d OK"',
}, 'Nagios::Plugin::Getopt' );
More Updates
Quoting isn't done properly, I think. When I use this configuration file:
[experiment]
percent=1
message="%d" OK
I get a very unusual quoted string: ""%d" OK"
s$$([},&%#}/&/]+}%&{})*;#$&&s&&$^X.($'^"%]=\&(|?*{%
+.+=%;.#_}\&"^"-+%*).}%:##%}={~=~:.")&e&&s""`$''`"e

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
