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 targets (from scouter agent)

    • Java Agent : Web application (on Tomcat, JBoss, Resin ...), Standalone java application
    • Host Agent : Linux, Windows, Unix
  • Monitoring targets (from Telegraf support) Since @2.0.0

    • Redis, nginX, apache httpd, haproxy, Kafka, MySQL, MongoDB, RabbitMQ, ElasticSearch, Kube, Mesos ...
  • Monitoring targets (from Zipkin-Scouter storage) Since @2.5.0


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.

Official modules:

  • Agent : gather performance information and send to the server

    • Java Agent (JVM Agent) : gathering profiles and performance metrics of JVM & Web application server(eg. Tomcat)...
    • Host Agent (OS Agent) : gathering performance metrics of Linux, Windows and OSX...
    • MariaDB Agent : [to be announced]
  • Server (Collector) : save the performance metrics from scouter agents or telegraf. The data is streamed to scouter client.

  • Client (Viewer) : client program based on RCP. (not support OSX Big Sur.)

  • Web API (Since @1.8.0) : scouter web apis to get counters, XLogs, profiles and another performance metrics via HTTP protocol.

  • Weaver (Since @2.17.0) : Provides the ability to directly control Scouter XLog and Profiles at the code level of Java applications.
