Since I wasn’t really blogging back then, I forgot to mention that Alert Logic received a great review at Security Magazine in its April 2007 issue. We got a “Best Buy” rating when compared against some of our competitors.
We were all very proud of the new releases of Threat Manager over the past year, so it was very good to be recognized for the work. A perfect score, no less! All 5 stars.
Velocity is the new O’Reilly conference aimed at discussing topics related to scaling web sites and applications on the Web. It seems really interesting, and I will try to attend.
Having access to some of the industry’s experts in scaling web sites will be really useful. In fact, Steve Souders is one of the program chairs of the conference, and he is also known as the creator of the very popular YSlow extension to Firefox.
Ok folks, just after testing out some new changes to this week’s release - I’ve uploaded a new version. Here are the following changes:
Changelog 1.2a
- changes line thickness to 1 for all graphs, 2 was too thick
for running at 5 minute intervals for the poller
- added several scripts for running and logging monitor agent and
report_generator
- changes talkback sripts to one script instead of 3
Today was at the faculty of Industrial Design in Delft to attend
the first 'c,mm,n Garage' event. c,mm,n - pronounced as
common - is a project to develop sustainable mobility.
It is led by Stichting Natuur en Milieu, The Netherlands Society for Nature and Environment and
currently the main participants are students from a number of
Dutch technical universities.
Right now, engineering efforts are focused on a clean,
remanufacturable car that runs on electricity generated by a
hydrogen fuel cell:
The car is almost completely built out of biodegradable plastics,
making it extremely light and environmentally friendly.
There is a YouTube Video available that shows off the
exterior design and which gives you a good impression of how open
and …
The problem
Hands up those that don’t monitor their production MySQL web server. I’m a little surprised by this, but I’ve visited several clients that have absolutely no monitoring other then “the customers will tell us when something is wrong”. The lack of system monitoring is one of the topics in my book “101 ways to screw up a successful startup”.
Why is monitoring important? First it can tell you when something is wrong, most monitoring systems introduce some level of constraints that trigger notifications via email, SMS or red flashing screens. Second, and I consider more important, is it allows you to analyze change and compare results over time. Let’s say you added more memory to your server, and then remembered to also increase the MySQL buffers appropriately. How much improvement did it make? Rather then “it seems faster”, you can have hard and fast numbers to back it up.

[Read more]Over the last several weeks I have been testing out the 2 mtron drives that easy computing company provided me. In fact I have been testing like a madman. Nightly I would kick off a batch of DBT2 tests, sysbench tests, bonnie++, and more. Each test changed something about the environment I was testing. RAID 1, RAID 0, with easy’s MFT, without the MFT, with the logs on SSD, With the logs on a raptor drive, etc. Each test run when it completed successfully would take roughly 12 hours. a typical example of a portion of one of these test runs is:
shutdown mysql
remove the data and log files
wait 5 minutes
startup mysql
wait 5 minutes
load a 200 warehouse DBT2 test
wait 5 minutes after the load is complete
run DBT2 test
rinse and repeat.
Minimally I have been doing a 40 active warehouse dbt2 test and a 60 active …

Just a note so folks at the conference can download them whenever they want. Folks not at the conference can, too but the slides don't give away the whole talk so I don't know how useful they're going to be.....
I’m reading the guide, but I’m still too busy with my work to
read it proficiently. In order to pass the exam I have to read it
again focusing all the details.
But, after reading the first 6 chapters (more then 50% of the
entire book) I found the guide useful and simply understandable …
and, thanks to lulu.com, it seems to me to be cheapest.
Well done authors!!!
