Features

Features already implemented:

• Interval based statistic framework
  MoSKito is an interval based statistic framework. That means that MoSKito gathers all monitoring data for each of user specified intervals as well, as for the whole running time (default interval). An interval is defined as the time between two measure points. For example, if you want 5 minute intervals and start the application at 12:00 pm, your first 5 minute interval will be generated at 12:05, next at 12:10 and so on. If you check the 5 minute value at 12:12 you will get the stats for 12:05 - 12:10.
  You can define any interval you wish as long as it can be expressed in minutes, hours or days.
• Easy stats logging
  MoSKito allows you to plug in own processors in the update cycle. You can get notified about an interval completion. There are predefined listeners which perform basic logging of all monitored values upon interval updates. To add your own logger you actually need one line of code. For java.util.Logger oder log4j even less, they are already prepared for you. See the net.anotheria.moskitodemo.logging package for examples.
• Built-in monitoring for web-apps
  MoSKito generate monitoring data for any kind of java application, not only webapps. Since MoSKito doesn't know your architecture you have to plug-in the monitoring yourself. However for webapps everything is already prepared. All you need is to extend the MoskitoHttpServlet instead of HttpServlet and rename your doGet method in moskitoDoGet and you are done. MoSKito demo-webapp illustrates that.
  If you use tomcat you can monitor your webapps directly by modifying context.xml and without changing code, read how.
• StatProducerRegistry for easy programmatic access to all available stat values.
• Webbased UI
  The webbased user interface for MoSKito allows you to instantly check and monitor all producers (monitorable objects) in the current vm. It allows you to check the stats online, sort by any of the generated values (hits, time, averages, errors), by categories (servlet/action/client/server/dao), implementations or instances.

Features which are ready but in testing:

• Remote monitoring data collection
  MoSKito can create snapshots of the statistics and is able to transport them over net to a remote server for archiving or offline evaluation. You can store the snapshots as strings, xml or in a database (or whatever you choose). Thus you will be able to find the difference in the application behaviour today compared to the behaviour a week ago. Or a month. Or a year.
• Virtual Stats
  Virtual Stats are stats, that are cumulated from other stats. If you have an interface with 10 methods in it, you can add stats for the interface (or impl) itself and count requests to it in every method, or you can define virtual stats which are updated on each method stats update automatically. Saves coding and gives you the possibility to to create multiple virtual stats on the same interface, i.e. all write methodes, all query methods ...

Features to come:

• Standalone GUI
• Use Case based monitoring over multiple shared monitoring nodes
• Conditional guards
• ... feel free to suggest some :-)
