1.下包

wget https://repo1.maven.org/maven2/io/prometheus/jmx/jmx_prometheus_javaagent/0.13.0/jmx_prometheus_javaagent-0.13.0.jar

2.配置java启动命令

-javaagent:/data/logs/jmx-exporter/jmx_prometheus_javaagent-0.13.0.jar=33334:/data/logs/jmx-exporter/config.yaml
/data/logs/jmx-exporter/jmx_prometheus_javaagent-0.13.0.jar:jar包门路
33334:监控端口
/data/logs/jmx-exporter/config.yaml:配置文件

java -javaagent:/data/logs/jmx-exporter/jmx_prometheus_javaagent-0.13.0.jar=33334:/data/logs/jmx-exporter/config.yaml -jar -server -XX:MetaspaceSize=256M -XX:MaxMetaspaceSize=256M -Xms2048M -Xmx2048M -Xmn256M -Xss512K -XX:SurvivorRatio=4 -XX:+UseConcMarkSweepGC /starit-buckyshop-stat.jar --spring.profiles.active=newsuper

3.配置jmx配置文件（发现所有监控项）

cat /mnt/jmx-exporter/config.yaml ---startDelaySeconds: 0lowercaseOutputName: falselowercaseOutputLabelNames: falsewhitelistObjectNames: ["org.apache.cassandra.metrics:*"]blacklistObjectNames: ["org.apache.cassandra.metrics:type=ColumnFamily,*"]rules:  - pattern: 'org.apache.cassandra.metrics<type=(\w+), name=(\w+)><>Value: (\d+)'    name: cassandra_$1_$2    value: $3    valueFactor: 0.001    labels: {}    help: "Cassandra metric $1 $2"    type: GAUGE    attrNameSnakeCase: false

4.配置prometheus

cat ~/kube-prometheus-0.5.0/manifests/prometheus-additional.yaml - job_name: 'jmx-exporter'  kubernetes_sd_configs:    - role: pod#  metrics_path: /metrics  relabel_configs:    - source_labels: [__address__]      action: keep      regex: '(.*):(.*)'    - source_labels: [__meta_kubernetes_pod_container_port_number]      action: keep      regex: '33334'    - source_labels: [__meta_kubernetes_namespace]      action: replace      target_label: kubernetes_namespace    - source_labels: [__meta_kubernetes_pod_name]      action: replace      target_label: kubernetes_pod_name  scheme: http

5.配置deployment

deployment减少jmx的container

6.导入grafana
