 포스팅은 WildFly Monitoring 방법에 대한 가이드입니다.


타 벤더사 WAS를 많이 다뤄본 제가 느끼는 Wildfly Monitoring 부분은 매우 취약하다 할 수 있습니다.

다만 CLI를 다방면으로 활용할 수 있어 이를 모니터링 방법을 가이드 하고자 합니다.

먼저 ThreadPool 모니터링 방법입니다.
모니터링은 Shell Script, CLI, WebConsole 환경에서 각각 테스트를 수행하였습니다.

[확인방법]

Shell

jboss-cli.sh --controller=[IP]:[PORT] --connect --command="/core-service=platform-mbean/type=threading:read-resource(include-runtime=true,recursive-depth=10)"

EX)

/home/wildfly/wildfly-10.1.0.Final/bin/jboss-cli.sh --controller=10.40.64.51:9990 --connect --command="/core-service=platform-mbean/type=threading:read-resource(include-runtime=true,recursive-depth=10)"

CLI

- /core-service=platform-mbean/type=threading:read-resource(include-runtime=true, recursive=true, recursive-depth=10)

Web Console

- Server: Standalone Server  =>  Monitor: JVM


[결과]

Shell & CLI
"thread-contention-monitoring-supported" => true,
        "thread-cpu-time-supported" => true,
        "current-thread-cpu-time-supported" => true,
        "object-monitor-usage-supported" => true,
        "synchronizer-usage-supported" => true,
        "thread-contention-monitoring-enabled" => false,
        "thread-cpu-time-enabled" => true,

        "current-thread-cpu-time" => 0L,
        "current-thread-user-time" => 0L,
        "object-name" => "java.lang:type=Threading"


WebConsole


다음으로 ConnectionPool(datasource) 모니터링 방법입니다.

[확인방법]

Shell

jboss-cli.sh --controller=[IP]:[PORT] --connect --command="/subsystem=datasources/data-source=[JNDINAME]/statistics=pool:read-resource(recursive=true, include-runtime=true)"

EX)

/home/wildfly/wildfly-10.1.0.Final/bin/jboss-cli.sh --controller=10.40.64.51:9990 --connect --command="/subsystem=datasources/data-source=ExampleDS/statistics=pool:read-resource(recursive=true, include-runtime=true)"

CLI

- /subsystem=datasources/data-source=epasds/statistics=pool:read-resource(recursive=true, include-runtime=true)

Web Console

- Server: Standalone Server  =>  Monitor: Subsystems  =>  Subsystem: Datasources

WildFly or JBoss의 경우 다소 모니터링에 취약점이 있으나, 반드시 모니터링 해야 하는 최소한의 요소들은 구현되어 있다는 것을 참고해야 겠습니다.
다음시간에 뵙겠습니다.

고맙습니다.
