As an IT manager, there are a lot of things you can do which directly impact your company’s bottom line. While the most obvious are direct hardware and software costs, an often overlooked aspect is energy/electricity consumption by computer systems. While servers need to be available 24/7, desktop systems only need to be available when the respective user needs it or for scheduled maintenance tasks. The rest of the time (usually more than 50% of the time), the system can stay in low power mode which reduces power usage, hence cost.
All Dell servers come with the Dell OpenManage Server Administrator software which has the ability to monitor and display system level indicators. Additionally, through the Alert Management tab you can configure actions to execute whenever an alert is triggered. Unfortunately there is no vehicle for applying uniform notifications to all events, so we are going to provide a script which configures all the alert actions to send an email notifying you of the respective event. While you could set these up manually, having a script is ideal as you can easily deploy this across multiple servers.
Linux has a rich set of commands for manipulating and accessing files. The du utility gives information on disk usage, and the sort utility can sort the results. Finally, we can run those results through the head command, which gives you the top 10 lines outputted through any other command. We’ll chain the commands together to get the output that we want.
Unless you have a special setup, you typically only need a single IP address from your ISP to run your network. With your network sitting behind a firewall/router, you can direct your incoming traffic to the appropriate servers to handle email, web, remote connections and anything else. The problem comes when you have multiple servers which need to receive traffic from a common port. Instead of adding more public IP addresses (and cost), we are going to show you how to handle this situation using on a single IP.
Have you ever used a tail -f on a logfile, only to find that it’s scrolling by way too fast for you to deal with? If you know exactly what you’re looking for, you can always grep the contents, but often you aren’t sure what you need to see. In this case, it’s useful to reverse grep instead.
A common function of many programs is the ability to send email. When working on development projects or doing product demos which utilize email, having an environment you know will work can be critical. For these situations, having a completely self contained email system, that is all emails “sent” never leave the local machine, is the answer.
Remote Desktop Connection is a useful feature in Windows that allows you to log on and view the desktop of another computer via your internet connection from your own computer. This article will explain how to use your local drives during a Remote Desktop session.
