Technology Errors

Windows Defender: This operation returned because the timeout period expired. (Error Code: 0x800705b4)

I recently received a new Dell laptop that has Windows 7 Ultimate 64-Bit as the operating system. A friend and I were discussing virus protection software as well as spyware protection software and how Windows 7 handles each. I am a big fan of Windows Defender so I was looking at the configuration on my Windows 7 computer and realized that the Windows Defender service was not starting. I hadn’t even realized this because I typically turn off the Virus, Spyware, and Firewall messaging that Windows complains about if you don’t have each installed the way the OS wants. So needless to say I was surprised that Windows Defender was stopped. It took me awhile to finally figure out how to resolve and I came across a bunch of issues that others may have so below I describe the error, steps I took to resolve, and final resolution.

Use Nagios To Check Process Size And Provide Alerts Based on Process Megabyte Size

Nagios is an awesome open source application that provides a way to monitor pretty much anything that you can think of on your network. There are tons of plugins written for Nagios that will monitor anything from PostgreSQL database size to the number of users logged into a server. Today I needed to start monitoring the size of a Ruby process that has been growing out of hand so the below is what I came up with being the best solution. Follow the directions below to deploy a Perl script that will use SNMP to retrieve Linux server process size.
