Application Performance Monitoring for Open Source S/Ws.

SCOUTER is an open source APM like new relic and appdynamics. (APM means application performance monitoring or application performance management.)

• Monitoring target (currently)

  • Java application - Web applications (on Tomcat, JBoss, Resin...), Standalone java applications
  • OS - Linux, Windows, Unix

• Monitoring target (to-be : contributing welcome)

  • Redis, Apach HTTPD, nginX, Nodejs ...

Users use application services on a system and the services use resources on the system. You should understand this context in order to manage the system performance efficiently. SCOUTER can help you.

• SCOUTER shows
  • Metrics about users : Active user, Recently used user, Today visitor
  • Metrics about services : Active service, TPS, Response time, Application profiles(method profile, sql profile, external call profile...)
  • Metrics about resources : Cpu, Memory, Network and Heap usage, Connection pools etc.
