    • ASM : using ASM library of OW2 (http://asm.ow2.org/) for BCI(byte code instrumentation)
    • Tools.jar : Java thread dumps, heap dumps, heap histograms, and the other powerful features provided by the JVM as the default.
    • JMX : Some counters for Tomcat & JVM such as GC Count, GC Times etc
  • Linux Agent : Performance for Linux, Window and OSX
    • PSUtil(https://github.com/giampaolo/psutil) : A cross-platform process and system utilities module for Python
    • Counters : Cpu, Memory, Disk, Network
  • MariaDB Agent : [to be announced]

• Server : received the data from agent and it stores the data. The data is serviced to clients.

  • Scala : Written in Scala. It will provide a variety of features and performance scalability that can not be written in Java.
  • HASH FILE : Server is using the hash index in order to store large data in files.
  • GZIP : Service performance data and profile data are stored is compressed.

• Client : provide the user interfaces

  • Eclipse RCP : SCOUTER is created as a standalone program. So the client can be connected to multiple servers at the same time. It makes easier that users monitor large scale systems.
  • SWT & GEF4 : Charts and Diagrams

SCOUTER is just simple. This configuration is simple. It will quickly provide the functions of monitoring OSS.

• It will be deployed and upgraded through the Internet.
• Clients are avaliable on Windows, MAC OSX and Linux.
• It will also be automatically upgraded.
• Key features such as Response-distribution, Active-service, Tag-count analysis are provided.
