centos7 安装jq并获取meanResTime和throughput

用jmeter性能测试之后会产生很多jtl，statistic文件，为了方便做excel表，需要自动读出吞吐率和平均响应时间。

1. 添加epel源

yum install wget
wget http://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
rpm -ivh epel-release-latest-7.noarch.rpm
yum repolist

2. 安装jq

yum install jq

3. 使用

使用命令如下

jq '.query[0].meanResTime' statistics.json #如果多个query，不知道jmeter中是否允许
jq '.query.meanResTime' statistics.json
jq '.query.throughput' statistics.json

产生的json格式的结果文件如下

  "Total" : {
    "transaction" : "Total",
    "sampleCount" : 360001,
    "errorCount" : 360000,
