集成MyPerf4J性能分析的基础镜像。1.0.0使用MyPerf4J 2.7.0版本。
镜像
docker pull registry.cn-shanghai.aliyuncs.com/shalousun/alpine-oraclejdk8-perf4j:1.0.0
k8s jvm监控
首先java应用需要使用该镜像作为应用的基础镜像。部署操作如下：
添加config-map
yaml添加一个config-map用于覆盖镜像中默认的MyPerf4J.properties。 config-map配置示例如下：
apiVersion: v1
kind: ConfigMap
metadata:
name: springboot-undertow-perf4j-config
namespace: default
labels:
k8s-app: springboot-undertow
data:
MyPerf4J.properties: |-
AppName=springboot-undertow
MetricsProcessorType=1
MethodMetricsFile=/MyPerf4J/log/method_metrics.log
ClassMetricsFile=/MyPerf4J/log/class_metrics.log
GCMetricsFile=/MyPerf4J/log/gc_metrics.log
MemMetricsFile=/MyPerf4J/log/memory_metrics.log
BufPoolMetricsFile=/MyPerf4J/log/buf_pool_metrics
ThreadMetricsFile=/MyPerf4J/log/thread_metrics.log
# Configure MethodMetrics TimeSlice, time unit: ms, min:1s, max:600s
MethodMilliTimeSlice=10000
# Configure JvmMetrics TimeSlice, time unit: ms, min:1s, max:600s
JvmMilliTimeSlice=1000
IncludePackages= com.benchmark.springboot
# Configure show method params type
ShowMethodParams=false
挂载MyPerf4J配置
在kubernates deployments上配置volume。
volumes:
- name: springboot-undertow-perf4j-config
configMap:
defaultMode: 0600
name: springboot-undertow-perf4j-config
关在volume
volumeMounts:
- name: springboot-undertow-perf4j-config
mountPath: /MyPerf4J/MyPerf4J.properties
readOnly: true
subPath: MyPerf4J.properties
修改启动参数
env:
- name: JAVA_OPTS
value: -javaagent:/MyPerf4J/MyPerf4J-ASM-2.7.0.jar -DMyPerf4JPropFile=/MyPerf4J/MyPerf4J.properties -server -Xmx2g -Xms2g -XX:+UseConcMarkSweepGC -XX:+CMSParallelRemarkEnabled -Djava.awt.headless=true
挂载MyPerf4J日志到本机
可以将MyPerf4J的性能分析日志挂载到宿主机。
volumes:
- name: perflog
hostPath:
path: /data/MyPerf4J/log # 宿主机挂载点
```
添加volume
```javascript
volumeMounts:
- name: perflog
mountPath: /MyPerf4J/log # 容器内挂载点
