html output cut off with actions component

Post by **WillemDH** » Fri Jul 29, 2016 6:22 am

When I make an action in the action component that is executing my FireMotD https://github.com/willemdh/FireMotD with the html theme, somehow the html is cut off. I'm pretty sure this worked in the past.

This is the action command:

Code: Select all

/usr/local/nagios/libexec/check_nrpe -H %host% -c firemotd -a '--Theme Html'

The output is a blank page. Checking the source of the generated webpage show that the html partially got through:

Code: Select all

Running: <b>/usr/local/nagios/libexec/check_nrpe -H nagiosqa -c firemotd -a '--Theme Html'</b><BR><hr><pre><!doctype html><html lang="en">
<head>
    <title>FireMotD</title>
    <meta charset="utf-8">
    <meta name="description" content="Generates a HTML MotD message">
    <meta name="author" content="OutsideIT">
    <!-- <script src="js/scripts.js"></script> -->
    <style type="text/css">
        h1 {
            font-family: Verdana;
            font-weight: normal;
            color: #024457;
            font-weight: bold;
            padding-left:30px;
        }
        table a:link {
            color: #666;
            font-weight: bold;
            text-decoration:none;
        }
        table a:visited {
            color: #999999;
            font-weight:bold;
            text-decoration:none;
        }
        table a:active,
        table a:hover {
            color: #bd5a35;
            text-decoration:underline;
        }
        table {
            font-family:Arial, Helvetica, sans-serif;
            color:#666;
            font-size:12px;
            text-shadow: 1px 1px 0px #fff;
            ba
</pre><hr><div style='float: right;'><a href='#' onClick="window.location.reload()"><img src='https://nagiosserver/nagiosxi/images/reload.png' alt='Run Command Again' title='Run Command Again'></a> <a href='javascript:window.close();'>[Close]</a></div>

Is this a problem of FireMotD or in the actions component?

What NRPE and check_nrpe versions are you using? There was a 1024-character limit for a long time that was fairly recently resolved, so that might be at play here.

Trevor,

Code: Select all

/usr/local/nagios/libexec/check_nrpe -h

NRPE Plugin for Nagios

Can I safely upgrade? Will NRPE be updated in a future XI update? Do I need to change anything hte client side? Can I downgrade again if something would come up?

Grtz

To get the benefits of the larger payload when using NRPE, you would have to install the NRPE agent on the remote server and also update the check_nrpe plugin on the Nagios server.
Below is a link to the KB article upgrade procedure you can follow along to do that.
https://support.nagios.com/kb/article.php?id=520
This link talks about the compatibility of version 3 of NRPE.

If you make a copy of the check_nrpe plugin on the Nagios server and reinstall the older version of the NRPE agent, that would be an easy way to go back if needed.

In this guide there is a specific section about installing the check_nrpe plugin only. It also shows you how to install it as /usr/local/nagios/libexec/check_nrpe_v3 which will prevent XI upgrades from touching it.

Then you would need to use different command definitions if you do that.
