cont regex 🔗 link

First off, thanks for coding this amazing piece of software, Henrik.

I'm trying to do a http content check of my Netgear print server's web
interface. The print server has two ports, and I'd like to have two
separate columns that show the status of the two printer ports. I've
tried to come up with some regular expressions, but they haven't
worked so far.

Here's a snippet of the HTML:
--------- HTML START ----------
<table width="530" height="230" border="0" cellpadding="0"
cellspacing=0 bgcolor="#ffbe39">
<div class="maintab">
<tr>

 <td>&nbsp;</TD>
 <th nowrap align="left">Parallel Port 1<p></th>
 <th nowrap align="left">Parallel Port 2<p></th>
</tr>

 <tr><td nowrap>&nbsp;&nbsp;&nbsp;&nbsp;Port Name</td>
 <td nowrap>P1</td>
 <td nowrap>P2</td>

 </tr>
 <tr><td nowrap>&nbsp;&nbsp;&nbsp;&nbsp;Status</td>
 <td nowrap>On-Line</td>
 <td nowrap>Offline</td>

 </tr>
 <tr><td nowrap>&nbsp;&nbsp;&nbsp;&nbsp;Print State</td>

 <td nowrap>Idle</td>
 <td nowrap>Idle</td>
--------- HTML END ----------

I'd like the column color to change if the status of the corresponding
printer port does not match the string "On-Line".
In this case, I'd prefer if the columns went clear instead of red.
I've tried prefixing "cont" with a question mark, but this doesn't
work. I'm running 4.2.0. Why is that?

I'm hoping you can help me create a regex that will do what I've described.

Good idea, but I assume I would have to run the extension script on a

script locally on the print server. Is it possible to run the script
on another box and have the results show up as if they came from the
print server?

Are you sure it's not possible to just make two different cont tests?
My knowledge of regular expressions is quite limited, but I assumed it
would be trivial to match those strings.

Also, does the cont check parse the raw HTML data or just the text
stripped of HTML? I mean, do I have to write a regex like...

On-Line</td>\n\n</tr> (needs escape characters, I know)

...or...

On-Line\s*$

...in order to match the status of the second port?

Thanks!

 I have dozens of scripts which run on my hobbit server (using its MIPs,
memory, etc.) which report on things all over the network and report
them as coming from the hosts being monitored.   Just make sure the
$MACHINE in the "bb" status command is the monitored host, not the
machine running the script.
