Skywalking-04:擴充套件Metric監控資訊

switchvov發表於2021-07-30

擴充套件 Metric 監控資訊

官方文件

Source and Scope extension for new metrics

案例:JVM Thread 增加 Metrics

修改 Thread 的定義

apm-protocol/apm-network/src/main/proto/language-agent/JVMMetric.proto 協議檔案中覆蓋 message Thread 的定義

message Thread {
  int64 liveCount = 1;
  int64 daemonCount = 2;
  int64 peakCount = 3;
  int64 deadlocked = 4;
  int64 monitorDeadlocked = 5;
  int64 newThreadCount = 7;
  int64 runnableThreadCount = 8;
  int64 blockedThreadCount = 9;
  int64 waitThreadCount = 10;
  int64 timeWaitThreadCount = 11;
  int64 terminatedThreadCount = 12;
}

重新構建 apm-network 專案

cd apm-protocol/apm-network
mvn clean package -DskipTests=true

PS:可以安裝 Protocol Buffer Editor 外掛,支援 Protocol Buffer 語法

修改 agent core 中 Thread Metrics 的提供類

直接使用如下程式碼覆蓋 org.apache.skywalking.apm.agent.core.jvm.thread.ThreadProvider 類

修改 ServiceInstanceJVMThread

直接使用如下程式碼覆蓋 org.apache.skywalking.oap.server.core.source.ServiceInstanceJVMThread 類,
ServiceInstanceJVMThread繼承了 Source 抽象類, Source 類是 Skywalking 中 oal 體系,資源及範圍的定義。

修改 JVMSourceDispatcher

org.apache.skywalking.oap.server.analyzer.provider.jvm.JVMSourceDispatcher 是一個 Source 分發類,將從 agent 接收到的 JVM 相關 Metrics 拆分成對應的 Source 。例如: ServiceInstanceJVMMemory 、 ServiceInstanceJVMThread 。
修改方法org.apache.skywalking.oap.server.analyzer.provider.jvm.JVMSourceDispatcher#sendToThreadMetricProcess 為如下程式碼:

    private void sendToThreadMetricProcess(String service,
            String serviceId,
            String serviceInstance,
            String serviceInstanceId,
            long timeBucket,
            Thread thread) {
        ServiceInstanceJVMThread serviceInstanceJVMThread = new ServiceInstanceJVMThread();
        serviceInstanceJVMThread.setId(serviceInstanceId);
        serviceInstanceJVMThread.setName(serviceInstance);
        serviceInstanceJVMThread.setServiceId(serviceId);
        serviceInstanceJVMThread.setServiceName(service);
        serviceInstanceJVMThread.setLiveCount(thread.getLiveCount());
        serviceInstanceJVMThread.setDaemonCount(thread.getDaemonCount());
        serviceInstanceJVMThread.setPeakCount(thread.getPeakCount());
        serviceInstanceJVMThread.setTimeBucket(timeBucket);
        serviceInstanceJVMThread.setDeadlocked(thread.getDeadlocked());
        serviceInstanceJVMThread.setMonitorDeadlocked(thread.getMonitorDeadlocked());
        serviceInstanceJVMThread.setNewThreadCount(thread.getNewThreadCount());
        serviceInstanceJVMThread.setRunnableThreadCount(thread.getRunnableThreadCount());
        serviceInstanceJVMThread.setBlockedThreadCount(thread.getBlockedThreadCount());
        serviceInstanceJVMThread.setWaitThreadCount(thread.getWaitThreadCount());
        serviceInstanceJVMThread.setTimeWaitThreadCount(thread.getTimeWaitThreadCount());
        serviceInstanceJVMThread.setTerminatedThreadCount(thread.getTerminatedThreadCount());
        sourceReceiver.receive(serviceInstanceJVMThread);
    }

java-agent.oal 增加相關指標

oap-server/server-bootstrap/src/main/resources/oal/java-agent.oal 新增如下語句

// 參考oal語法
instance_jvm_thread_deadlocked = from(ServiceInstanceJVMThread.deadlocked).longAvg();
instance_jvm_thread_monitor_deadlocked = from(ServiceInstanceJVMThread.monitorDeadlocked).longAvg();
instance_jvm_thread_new_thread_count = from(ServiceInstanceJVMThread.newThreadCount).longAvg();
instance_jvm_thread_runnable_thread_count = from(ServiceInstanceJVMThread.runnableThreadCount).longAvg();
instance_jvm_thread_blocked_thread_count = from(ServiceInstanceJVMThread.blockedThreadCount).longAvg();
instance_jvm_thread_wait_thread_count = from(ServiceInstanceJVMThread.waitThreadCount).longAvg();
instance_jvm_thread_time_wait_thread_count = from(ServiceInstanceJVMThread.timeWaitThreadCount).longAvg();
instance_jvm_thread_terminated_thread_count = from(ServiceInstanceJVMThread.terminatedThreadCount).longAvg();

修改 apm.yml

oap-server/server-bootstrap/src/main/resources/ui-initialized-templates/apm.yml 檔案的 APM 皮膚下的 Instance 項增加如下配置

{
  "width": 3,
  "title": "JVM Thread Count (Java Service)",
  "height": "250",
  "entityType": "ServiceInstance",
  "independentSelector": false,
  "metricType": "REGULAR_VALUE",
  "queryMetricType": "readMetricsValues",
  "chartType": "ChartLine",
  "metricName": "instance_jvm_thread_live_count, instance_jvm_thread_daemon_count, instance_jvm_thread_peak_count,instance_jvm_thread_deadlocked,instance_jvm_thread_monitor_deadlocked"
},
{
  "width": 3,
  "title": "JVM Thread State Count (Java Service)",
  "height": "250",
  "entityType": "ServiceInstance",
  "independentSelector": false,
  "metricType": "REGULAR_VALUE",
  "metricName": "instance_jvm_thread_new_thread_count,instance_jvm_thread_runnable_thread_count,instance_jvm_thread_blocked_thread_count,instance_jvm_thread_wait_thread_count,instance_jvm_thread_time_wait_thread_count,instance_jvm_thread_terminated_thread_count",
  "queryMetricType": "readMetricsValues",
  "chartType": "ChartBar"
}

如果不清楚新增位置,可以直接使用如下配置,覆蓋 oap-server/server-bootstrap/src/main/resources/ui-initialized-templates/apm.yml
