Hi everyone, In our logfiles we store response times for the requests. What's the most efficient way to calculate the median response time, the "75/90/95% of requests were served in less than N time" numbers etc? (I guess a variation of my question is: What's the best way to calculate the median and standard deviation of a bunch stre...
If I want the access log for Cherrypy to only get to a fixed size, how would I go about using rotating log files? I've already tried http://www.cherrypy.org/wiki/Logging, which seems out of date, or has information missing. ...

Response time can be enabled like so: #LogFormat "%h %l %u %t \"%r\" %>s %b" # Default LogFormat LogFormat "%h %l %u %t \"%r\" %>s %b %D" # LogFormat including res...
I've got a distributed deployment of ±20 clients using the same stored procedure to create a record and then attach detail records. We've noticed gaps in the identity fields of the master record. We are not using a transaction in this instance so the only reason we can come up with for the gaps is that one of the developers is swallowing...
Apologies if this is a dumb question, I've limited network knowledge. If I sent a string to port 80 on UDP, would the server / receiving IP log it? I'm pretty sure it wouldn't in access logs, but what about firewall logs? ...

I'd like to find out how current google's cached copy of a large set of pages is. I think I need to look in the logs for IP's, check to find user-agent "googlebot", then export a list that says each page and when it was last visited. I imagine this could be a cron job that runs weekly. If this is right, how would I write the s...

What do I have to do to make 20k mysql inserts per second possible (during peak hours around 1k/sec during slower times)? I've been doing some research and I've seen the "INSERT DELAYED" suggestion, writing to a flat file, "fopen(file,'a')", and then running a chron job to dump the "needed" data into mysql, etc. I've also heard you need ...
I have processed a SSAS cube. After it was done processing, I hit the close button - and then realized that I should have saved the output. I think SSAS stores the processing log as a text or XML file, but I do not know what folder to look into. Can someone direct me to retrieving processing logs? ...
