Question

我正在用wrk2作为Jenkins的一项工作进行负载测试。我想将负载测试的结果发送给Graylog，但我只想存储Requests / Sec和平均延迟。

输出内容如下：

----------------------------------------------------------
  130 requests in 30.02s, 13.44MB read
  Socket errors: connect 0, read 0, write 0, timeout 1192
Requests/sec:      4.33
Transfer/sec:    458.47KB

有人知道我应该如何提取请求/秒（在底部）和平均延迟作为JSON参数发送吗？

预期输出为："latency": 16.2, "requests_per_second": 4.33

Answer 1

您没有提供预期的输出，因此您的问题不清楚，但这是您想要的吗？

$ awk 'BEGIN{a["Latency"]; a["Requests/sec:"]} ($1 in a) && ($2 ~ /[0-9]/){print $1, $2}' file
Latency 16.20s
Requests/sec: 4.33

根据您向问题中添加预期输出进行了更新：

$ awk '
    BEGIN { map["Latency"]="latency"; map["Requests/sec:"]="requests_per_second" }
    ($1 in map) && ($2 ~ /[0-9]/) { printf "%s\"%s\": %s", ofs, map[$1], $2+0; ofs=", " }
    END { print "" }
' file
"latency": 16.2, "requests_per_second": 4.33
