Managing Computer Health in Multiple Places

I have a few computers under my control. Unfortunately, not all of them are in the same room. Actually, most are spread all around the country. I have essentially two computers under my direct control, with a few others that I tend to use.

It becomes very important when you start needing these computers to do tasks, such as serve up websites, provide SSH servers, or other such services. Unfortunately, power interruptions, and crashes do happen. A lot of times, if a server goes down, you need to wait until you can get somebody to physically press the button if it’s remote, or provide some details on network access (did just the network go down, or did the actual computer go down, or both). Collecting information about a server after it has gone down is a trivial task, just look through the logs. The big crunch here is, what about real-time outage information? Having a server “ping” a webpage every 5 minutes, uploading the latest load average, memory information, disk usage, uptime, and system log information should provide adequate information to provide a decent report on system health.

Over the weekend, I want to see if I can write some code and set up a little site where I can monitor all my computers, and maybe even try and send commands to them (security and authentication being somewhat of a problem here).

Update: I started work on this on the weekend, and I already have it working. Visit data.vectec.net/uptime for live uptime information for three of my Linux computers (Mac OSX coming soon I hope).

Struggle For More Pixels

Anybody that uses a computer a lot, usually would agree that there’s just never enough pixels on the screen to do what you want. This term, my old roommate left his monitor behind, and I’ve taken it into my room for use with my laptop. My laptop’s display is 15.4 inch widescreen, with a native resolution of 1280×800. The current monitor I’m using has a native resolution of 1680×1050 (just shy of 1080!), however, sometimes even that doesn’t feel like enough. Having a dual monitor setup is perfect, but I wish it worked better in Linux for a setup where both monitors might be a different size.

X seems to think that the best way to do this is to make a square screen, even if one screen is taller pixel-wise than the other, meaning I don’t get the bottom of the screen on the smaller monitor. The other side-effect here is that the KDE panel goes across the bottom all the way, even if I wanted it just to be on one screen (Windows does this, and it’s a feature I like). Dual monitors is something Windows gets right, and Linux absolutely fails at. Then again, there might be a solution I don’t know about. At work, I have a nice setup. I have a nice large square screen, and spend all day in VMWare, so switching around VMWare has become second nature.

I’m also thinking within a year I’m going to have to get my laptop replaced. Heat has became a big issue for it, and even a chillpad struggles to keep it cool. I’ve tried dusting it a couple times, but unfortunately the air circulation on it has never been that great. I have the most problems when running something that gives the GPU a pretty good workout, usually pushing the sensor temps over 100C, and making the bottom of the laptop too hot to touch. In my dual monitor setup, I must remember to keep the laptop lid open, even if the screen is in use to promote air circulation.

Who Turned Off the Pump?

Every weekend, my friends and I go to a pub called “The Lieutenants Pump” for bunch at about noon. Last week we got this letter:

Dear Valued Patron,

I regret to inform you that the Lieutenant’s Pump has been assessed a two day Liquor license suspension by the Alcohol and Gaming Commission. The Commision found us guilty of being over capacity by five people on the patio during last years Stanley Cup Finals.

On the night of the infraction, we did everything in our power to control the patio but did not foresee people jumping the fence. We had staff supervising the patio and when people hopped the fence they were immediately escorted off.

We were not aware at the time that this would be considered insufficient by the Commission. Somehow, the Commission expected us to prevent the fence jumping. Short of barbed wire and electrification I’m not sure how this could have been accomplished. None the less, in its wisdom the Commission has concluded that the suspension is warranted as a general deterrent to other operators and as a specific deterrent to us letting it happen again.

The Lieutenant’s Pump will be closed October 11, 12 and 13 which is Thanksgiving weekend including Monday.

I apologize in advance for any inconvenience this closure will cause. Any concerns about this situation should be directed to:
