We are very pleased to announce the release of MONyog 2.5 Beta 1. This is a major upgrade from the previous releases.

MySQL currently lacks advanced query profiling tools like SQL Server’s Query Profiler. While the current breed of MySQL monitoring tools provide monitoring and advisory information on various system metrics, they don’t help in pinpointing the problematic queries. No amount of hardware upgrades or tuning of mysql.cnf / mysql.ini parameters can match the performance gains that can be achieved when problematic queries and identified, rewritten and/or appropriate indexes are created.

MONyog 2.5 helps in identifying problem SQL by

1) Analyzing the general query log
2) Analyzing the slow query log
3) If the above mentioned logs are unavailable then MONyog query sniffer can capture the results of SHOW PROCESSLIST at user-defined …

Bug fixes:

* The new version 3 release of Mozilla Firefox (now in RC) had a flickering issue with MONyog and the login page did not load correctly in that browser version.

Performance improvement:

* Earlier MONyog was semaphore intensive. That could result in reaching the ‘limit of semaphores that can be created by the kernel’ in some systems. MONyog 2.04 will use less semaphores. Another symptom was that a large number of small and zero-size files could be left behind (in system TEMP folder on Windows and in MONyog/bin folder on Linux). This is also solved with this.

Bug fixes:
* In some situations where SSH connections failed (including if MONyog was not able to connect to MySQL, wrong SSH authentication details for tunnelling etc.), sockets were not being closed and it could result in that many sockets were kept in CLOSE_WAIT state. (note: connections to MySQL not using SSH were not affected!)
