Made2Mentor’s MacGyver Moment Meme

Denny Cherry Denny Cherry Profile: Denny Cherry

David Stein (@Made2Mentor) started a neat new post My McGuyver Moment and tagged Brent Ozar (@BrentO) who tagged me.  In David and Brent’s post they talked about building something from nothing that the company ended up needing for several years.

I to have had my share of shoestring budget projects that I’ve had to deal with putting together.  The one that I’m probably the most proud of was when I worked at EarthLink.  We had a rather large call center, at the time it was a single office, but over time it grew to 7 offices and 3 outsourced call centers, but I’m skipping ahead here.

On the things which our call center supervisors were supposed to do was grab the call center queue stats every 4 hours and email them to management’s pagers.  Needless to say this seemed like a rather big waste of time to actually have a person sum up these numbers in Excel and then send out an email.

So I built a quick VB app which would log into the PBX, gather the required numbers and send out the email.  This was cool and all, and took about a day to put together.  After this I decided to put the data out on a web server so that everyone else that didn’t have access to the rather expensive Lucent PBX software could see the data.  So once everyone thought that was awesome, we look it to the next logical step and started exporting all the call center data and created web pages which would allow anyone to see the data.

Now these weren’t fancy dynamic pages.  They were just static HTML files that refreshed themselves every few seconds and were rewritten by the app I wrote every few seconds.  Now on the server side of things the PBX server that I had to connect to was a closed system meaning that my only option to connect to it was via the management tool.  At the time there was no scripting support in the app, so I had to write an app which would send keystrokes to the client app and export the data to flat files, then process the files into the needed html files.

This lasted for a couple of weeks until we started adding more groups into this mix.  It would end up taking several minutes to process everything.  I then started loading the data into an Access database and using classic ASP to allow the users to select the data that they wanted to see.  After a couple of weeks of loading data into Access every few seconds Access blew up so we upgraded to SQL Server.

After some time we added more and more call centers to the company we added more and more computers doing processing.  Now when all this started we were running on old P2 400Mhz workstations all running like 128 Megs of RAM for each machine.  By the time we were done with this we had a view computers all these crappy workstation class machines except for one rack mount server (see the picture of my desk below).

By the time I left EarthLink (more specifically I was tossed out kicking and screaming as all our jobs were off-shored) we had equipment in 5 offices in additional to all the machines running under my desk.  There were somewhere around 4000 internal users accessing the web app and we were actually feeding hold time information to the customer facing website so that customers could see what the wait time would be in real time.  By the time everything was said and done we had saved hundreds of thousands of dollars in Lucent/Avaya licensing fees as each new Lucent PBX we brought only the server and only needed the default 5-10 licenses that came with the PBX system.

Needless to say this was probably the biggest spit and chewing gum project that I’ve ever worked on.  The total cost to the company was only a few thousand dollars (the rack mount server).  Our SQL License was covered under our Enterprise Agreement, and all the workstations were older machines which weren’t in use any more by Tech Support (they liked it when we stole the old machines, it gave them an excuse to order new ones).

Now, as for the people that I’m going to tag I’m going to go with some people that don’t always get pulled into these.

Jessica and Goeff haven’t been going a lot of blogging recently.  Hopefully this will help them start writing more often.  Tom blogs like crazy, and one more just isn’t going to hurt him.  I picked these three because I’m curious to see what these folks have had to band-aid together with duct-tape over their careers.

    That's a pretty cool story, I love saving money! Looks like I'll have to come up with one now thanks to Geoff. Actually, your story kind of reminds me of what I'm having to do with our current Data Warehouse :-(

    Hello, I once wrote a small BASIC program for a lap top to track pressure and water volume reducing the need from three people to one. They promptly asked me to leave. - Not really promptly but within a couple of years. But the guy who fried thousands of dollars worth of electronics stayed until he retired.
