Debra Curtis, David Williams

When embarking on an event correlation and analysis (ECA) project, it's important to consider the right event management specialist  products, manager of managers (MoMs) and business service management (BSM) options, pulling together the appropriate sources and data types supported by the right ECA architecture.

Tuning Nagios

In order to allow the Nagios system to run thousands of alert checks per minute, we needed to tune a few things in Nagios.

First we moved the database and program directories /var/lib and /usr/local over to a high speed EMC disk Array.

Create a RAM disk for Nagios tempory files

I created a ramdisk by adding the following entry to the /etc/fstab file:

none                              /mnt/ram                        tmpfs   size=500M           0 0

Mount the disk using the following commands

# mkdir -p /mnt/ram; mount /mnt/ram

Alert Types to setup in Nagios

a.  Regular Expression HTTP monitor

We need the ability to monitor a part of a page.   The content needs to be able to match content on a page using regular expressions.  Also needed is the ability to log into the page.  Example of expression: /Temp_P18.*\n.*\n.*;(.*) Deg. C.*\n.*\n.*\n.*;(.*) %/

We need to be able to catch the values in the "()" areas listed above and check against those values.

We're experiencing issues with some monitors giving a HTTP-FORBIDDEN issue with the check_http scripts.

Which is better #Fedora 13 or #Ubuntu 10.04

The state of the Linux desktop

I'm a fan of Fedora and Ubuntu, but for different reasons. Fedora, while unpolished, is a solid distro for adventurous Linux users and developers who want to be on the bleeding edge. Power users deserve a good distro that is usable and feature-complete without a lot of polish or distraction - and that's what Fedora is.
Ubuntu is the flip side. It's very polished, closing in on Apple in terms of usability and applications. It's not quite there yet, but getting closer and certainly a persuasive distro for people switching from Windows. If you're looking to get a friend started with Linux, don't hesitate to begin with Ubuntu.

Foscam FI8918W control script for ZoneMinder

Based on origional article by Howard at Durdle.com

Updated for Fedora 19

The Foscam cameras have pan, tilt and the ability to set and move to preset locations.

The Foscam control script for ZoneMinder which I found on the ZoneMinder wiki was a good starting point, 

To install the Foscam control script: find where the control scripts are installed on your distro. In mine I found the files in:

  /usr/lib/perl5/site_perl/5.8.8/ZoneMinder/Control/

or CentOS

  /usr/share/perl5/ZoneMinder/Control/PanasonicIP.pm

or Fedora 19

  /usr/share/perl5/vendor_perl/ZoneMinder/Control/PanasonicIP.pm

If you’re not sure where to look, run the command:

  locate PanasonicIP.pm

How to fix favicon.ico page not found in Drupal

Thanks to Foobarist for the following:

Problem / Symptoms

Your Drupal 5.x or 6.x installation is throwing "Page not found" errors for favicon.ico.  (You can see this in Admin > Logs > Recent Log Entries > Page Not Found)

What's going on?

There is no favicon.ico in the Drupal root directory. 

Drupal's themeing system inserts the following line into your website's source.  This is why when you view your site, you see a favicon in your browser, even though there is no favicon.ico in Drupal's root directory.
