In the near past I got frustrated searching for a tool to export from MsSQL express to proper CSV. As always the frustration lead me to google, and found the post on stackoverflow and to digital point forums and a lot of other places. All these had some or the other issues with us. One being the MsSQL not hosted on our servers and we dont have access to the GUI tools, the second is that I am a bit towards the fag end when Microsoft Technologies are in the anvil. Finally there was no other way and what I did was to migrate our PHP MySQL wrapper to support MsSQL.
The profiler and sampler has been bundled into a single download, but is now two wordpress plugins. Though this has issues that this will be plugged into the wordpress flow after init and that logging is done on shutdown hook, some of the database calls are never logged. Still that is not an issue as mostly slowness would be caused by database calls from the theme and plugins. Note that logging may make system more slow and this is for identifying the bottlenecks and should never be left on for long times. Features like Log requests from IP, Log requests from IP to specific URL, Enable/Disable, Log Frequency are in the wishlist. Currently when you enable, the profiler starts logging, and creates new file for every hour. This is stored into the UPLOAD_DIR/wp_php_my_profiler with <Year-month-date-hour>.log as filename, and posted into the $wpdb-posts table with post_status = private, and post_type = profiler_log, Once logging is done, and before going for analysis, better deactivate the Profiler. Log Analyzer creates a menu entry in the admin side, and shows the logs from the $wpdb->posts table with the above properties in a tabular form, with actions ‘Analyze’ and ‘Delete’. The plugin is provided for advanced users and debuggers to find issues and bottlenecks in their plugins or themes. Download the plugin PHP MyProfiler Wordpress Plugin (126)
We just activated our url compressor WP to Twitter. Trying to enable the WP to Twitter to work with the bz2 compressor. In fact this is a test post for the same. The WP to Twitter is simply superb, thankyou Doleson.

Its been over a year since we started bz2.in url compression for inhouse projects at Saturn and is being in use for Asianet India and this blog. Recently for a new project we absolutely needed an integrated url shortner, which finally gave shape to the initial version.

Though there are far and wide systems for live debugging, and the sort, for forensic or load analysis, our php-extjs framework did not have anything pre planned, other than some query loggers, and background processing systems to log into db etc. While recently the Master MySQL server started showing variations in the cacti patterns (normal was about 4 to 20 in working window, but was steady between 35 and 40 in the tantrum period), we started to worry and could not identify the situation. Also restarting all application servers and clearing the session store would immediately drop the MySQL fsync graph to a standard pattern. This is the time when I looked for a input logger for Apache, and found about the dumpio, but needed the webserver to be restarted. Actually the time was ripe that the application was in a tantrum, and the MySQL graphs showing about 35 fsyncs average.
Revisiting Importance of event logging in server side scripting and other articles on the net, the out come was a class with a single static method. This was designed to pick and log any input. This was later moved as the lite version, and a full version capable of capturing the output also was built.

Just searched for a similar one, and could not find any, converted one such function which I had in hand, and is posted here Function to format bytes in human readable format, which was in php.

Recently in a project where the application was deployed across multiple servers, the Client QA as well as Support Team wanted a better monitoring of all the servers in the production. It was too much to provide everybody with shell access and ask them to monitor using top. Well after a lot of digging through the wonderful search index of Google. And with insights from Paul Colby vide his article Calculating CPU Usage from /proc/stat, and various comments of Memcache usage through telnet along with the /dev/tcp socket connections it was just a matter of using some nifty shell processing before I could store each machine cpu values, loadavg, and running tasks as a json encoded string into memcache on one of the hosts with hostname as the key.

Actually it is ages since I sat down to scribble something. Well this one could not be avoided. Hence here it is.
In one of our FTE projects, we had faced a complication that Memcached on one node was using 100% cpu and php-cgi was complainging that the same node was not permitting any more memcached connections. The configuration was as what all says, session.save_handler = memcache, session.save_path = “tcp://

Recently we were facing some difficulties, where we had facilitate implementing a copy of an application on a development environment with our client. The most difficult part was that though we could coax php to load libraries, we could not install any system services. We were supposed to install only a web application to a pre-configured virtual host. Since we had enjoyed the facility of having Memcache at our own development environment, some core part of the application which was required only when users are logged in, was using the Memcache. Also our database abstraction layer was heavily depending on the memcache library. We immediately identified that the requirements were not met and specified that the environment was not as we required. But the support people were so adamant that they insisted us to proceed by commenting out all references to the class. Well I can also be tough.
