You might not notice it, but you may be making hundreds – or even thousands – of decisions everyday. Unchecked, these decisions will burn you out. Sometimes it is the number of different decisions that causes the damage, in other cases it is the constant churn of a single decision that roasts your ability to […]
In software development, there is a simplistic model that says that risk is a function of time, or money. Lots of graphs have been published to show that as the duration of a project increases, so does the risk… or as the cost of the project increases the risk goes up. Of course, in many […]
The following Log Parser Studio query will find common erroring URLs. You could adapt this to find common addresses for other status codes too. SELECT TOP 20 cs-uri-stem, COUNT(*) AS Total, MAX(time-taken) AS MaxTime, AVG(time-taken) AS AvgTime FROM ‘[LOGFILEPATH]’ WHERE date > SUB(TO_LOCALTIME(SYSTEM_TIMESTAMP()), TIMESTAMP(‘0000-01-02 00:00’, ‘yyyy-MM-dd HH:mm’)) AND sc-status = ‘500’ GROUP BY cs-uri-stem ORDER […]
If you are regularly updating your servers, you may notice that after re-starting the disk space is not actually given back (i.e. the temporary files downloaded for the update remain).

But before you grab a type definition, let’s stop and think for a minute. TypeScript does indeed bring you lots of benefits in terms of type checking, and editor features such as auto-completion […]
If you are getting suspicious traffic, it often comes from a range of IP addresses. The below queries get the count using the first three octets of an IP address, so for “192.168.0.1” it will return “192.168.0” and a count of all traffic for the 192.168.0.1/24 range (192.168.0.1 – 192.168.0.255). To get the first three […]
If you want to add my set of Log Parser Studio custom queries to your LPS library, follow these instructions… Note: if you want to merge these with your existing queries, just copy the inner nodes into your LPS library file – if you just want to use my custom set without searching through the […]
You may have seen how to find guilty IP addresses in my post Using Log Parser Studio to Find Guilty IP Addresses, but if you have enabled the logging of X-Forwarded-For IP addresses in IIS you may want to use this updated version, which gets the top offending IP addresses based on the X-Forwarded-For header: […]
