Bash and Python NRDP Clients for Nagios

By Scott Wilkerson on February 16, 2012

Now available 2 new clients to send passive check results to Nagios Remote Data Processor (NRDP) server.

We have just released:
send_nrdp.sh Bash NRDP Client
send_nrdp.py Python NRDP Client

You no longer need to install PHP or Perl on your client machines to run passive checks with NRDP. Both of these implementations can accept result piped from STDIN and you can change the delimiters to whatever you like.

STDIN results should be in the following order, for HOST checks:

HOSTNAME    STATE    OUTPUT

1	HOSTNAME STATE OUTPUT

for SERVICE checks

HOSTNAME    SERVICENAME    STATE    OUTPUT

1	HOSTNAME SERVICENAME STATE OUTPUT

Additionally, the bash version can take an XML file of check results formatted like so:

&lt;?xml version='1.0'?&gt;
&lt;checkresults&gt;
&lt;checkresult type="host" checktype="1"&gt;
  &lt;hostname&gt;YOUR_HOSTNAME&lt;/hostname&gt;
  &lt;state&gt;0&lt;/state&gt;
  &lt;output&gt;OK|perfdata=1.00;5;10;0&lt;/output&gt;
&lt;/checkresult&gt;
&lt;checkresult type="service" checktype="1"&gt;
  &lt;hostname&gt;YOUR_HOSTNAME&lt;/hostname&gt;
  &lt;servicename&gt;YOUR_SERVICENAME&lt;/servicename&gt;
  &lt;state&gt;0&lt;/state&gt;
  &lt;output&gt;OK|perfdata=1.00;5;10;0&lt;/output&gt;
&lt;/checkresult&gt;
&lt;/checkresults&gt;

<?xml version='1.0'?>

<hostname>YOUR_HOSTNAME</hostname>

<output>OK|perfdata=1.00;5;10;0</output>

</checkresult>

<hostname>YOUR_HOSTNAME</hostname>

<servicename>YOUR_SERVICENAME</servicename>

<output>OK|perfdata=1.00;5;10;0</output>

</checkresult>

</checkresults>

Nagios Mobile 1.0

By Mike Guthrie on December 21, 2011

Nagios Mobile is a lightweight web interface, based on the Teeny Nagios project by Hirose Masaaki. Nagios Mobile is a PHP web-based application designed for Mobile and touch-screen devices.

Key Features:
– User-level authorization for hosts, services, and commands that match Nagios Core.
– Filtered lists to quickly identify and respond to unhandled problems
– Acknowledge problems, Disable/Enable Notifications, or Schedule Downtime for authorized hosts and services
– Works with any Nagios 3.x installation
– Support for APC data caching for faster page loads
– Support for both webkit and non-webkit enabled devices

My favorite kinds of development projects always end up being on the front-end, and I certainly can’t claim much on the interface design for this project, as that goes to community member Hirose Masaaki using the JQuery Mobile framework. We loved the front-end design that he came up with for the Teeny Nagios project, so we did some revisions to the server-side code underneath to allow for host and service filtering by state, more complex permissions, data caching, and improved scalability for larger installations. We also added some code to allow Nagios Mobile to work from essentially any mobile browser.

Nagios V-Shell 1.8 Release

By Mike Guthrie on September 19, 2011

Over the past few years, there’s been a strong outpouring of requests for an updated interface for Nagios. We released Nagios V-Shell just about a year ago now, and we’re happy to see that it currently stands as the most popular item on the Nagios Exchange, with over 100,000 views! I don’t usually post to labs every time I make an update to V-Shell, but I thought this time around would be worth mentioning. I’ve spent the last few weeks doing a major overhaul of the permissions in order to mirror the same permissions scheme that people are used to in Nagios Core. Initially V-Shell has limited user-level control in regards to permissions, but as of v1.8 I’m pleased to say I’ve finally got that major TODO crossed off my list. V-Shell now supports user-level access, as well as read-only access to match the permissions scheme of Nagios Core. Feel free to check out V-Shell 1.8 on the Nagios Exchange.
