JMeter 命令行测试
- XX:MaxMetaspaceSize(jdk8的参数)
这个参数用于限制 Metaspace 增长的上线，防止因为某些情况导致 Metaspace 无限的使用本地内存，如果超过设定的值就会触发 Full GC，此值默认没有限制，应取决于系统内存的大小，JVM会动态地改变此值。例如：-XX:MaxMetaspaceSize=4096M - -Xmx2048m
设置堆内存最大值为 512m - Xms 1g
设置堆内存最小值1g(ps:-Xms 和 -Xmx 实际上是 -XX:InitialHeapSize 和 -XX:MaxHeapSize 的缩写。例如：-XX:InitialHeapSize=128m -XX:MaxHeapSize=2g)
JMeter 插件安装介绍
Plugins Manager https://jmeter-plugins.org/install/Install/
AutoStop Listener：尤其在 CI 运行中，或线上压测时，需即时止损
1、JMeter 客户端异常搜集 filebeat + elk
ElasticSearch：日志存储
FileBeats：日志搜集
Kibana：展现
wget https://artifacts.elastic.co/downloads/beats/filebeat/filebeat-oss-7.5.1-darwin-x86_64.tar.gz --no-check-certificate
tar -xzf filebeat-oss-7.5.1-darwin-x86_64.tar.gz
Vi filebeat.yaml
几种方式的 Listener
Result Listener，记录日志。
JSR223 Listener
if (prev.getResponseCode()!=200)
{
log.error(prev.getResponseDataAsString());
}
ctx-（JMeterContext）-gives access to the context
vars-（JMeterVariables）-gives read/write access to variables:vars.get(key);vars.put(key,val);vars.putObject
props-（JMeterProperties - class java.util.Properties）-e.g. props.get("START.HMS");props.put("PROP1","123")
prev-（SampleResult）-gives access to the previous SampleResult(if any)
ctx：http://jmeter.apache.org/api/org/apache/jmeter/threads/JMeterContext.html
vars：http://jmeter.apache.org/api/org/apache/jmeter/threads/JMeterVariables.html

2、Promethues + Node_Exporter 机器监控
Promethues 安装
Docker Pull prom/promethues
docker run --name prometheus -d -p 9090:9090 --privileged=true -v
/home/mydata/prometheus.yml:/etc/prometheus/prometheus.yml prom/prometheus
http://47.93.32.161:9090/targets
scrape_configs
job_name:prometheus
static_configs:
targets:['localhost:9090']
labels:
instance:prometheus
job_name:linux
static_configs:
targets:['47.93.32.161:9100']
labels:
instance:node
Node Exporter 安装
wget https://github.com/prometheus/node_exporter/releases/download/v0.18.1/node_exporter-0.18.1.linux-amd64.tar.gz --no-check-certificate
docker cp ../node_exporter-0.18.1.linux-amd64 :/
http://47.93.32.161:9100/metrics
node_cpu：系统 CPU 使用量
node_disk：磁盘 IO
node_filesystem：文件系统用量
node_load1：系统负载
node_memeory：内存使用量
node_network：网络带宽
node_time：当前系统时间
go_：node exporter 中 go 相关指标
process_：node exporter 自身进程相关运行指标
3、Spring JVM、Mysql、Redis、Mongodb 监控
Add Mvn Package
io.micrometer
micrometer-registry-prometheus
1.3.5
Mvn package
Push Images 到远程仓库
Docker Image 暴露对外端口：
docker run -p 9100:9100 -p 8001:8001 -p 8085:8085 --name mall-portal --link mall-mysql:db --link mall-redis:redis --link mongo:mongo --link rabbitmq:rabbit -v /etc/localtime:/etc/localtime -v /mydata/app/protal/logs:/var/logs -d mall/mall-portal:1.0-SNAPSHOT
Mysql 监控
GRANT REPLICATION CLIENT,PROCESS ON *.* too 'exporter'@'%' identified by 'exporter';
GRANT SELECT ON performance_schme.* TO 'exporter'@'%';
flush privileges;
docker run -d --restart=always --name mysqld-exporter -p 9104:9104
-e DATA_SOURCE_NAME="exporter:exporter@(47.93.32.161:8306)/" prom/mysqld-exporter
Consul 服务发现方式，无需重启加载新指标
docker run --restart=always --name consul -d -p 8500:8500 consul
