从wrk输出中提取文本

Question

我正在使用wrk2作为Jenkins的一项工作运行一个负载测试。我想将负载测试的结果发送到Graylog，但是我只想存储请求/Sec和平均延迟。

以下是输出的样子：

Transfer/sec:    458.47KB

有人知道我如何提取请求/秒(底部)和作为JSON参数发送的平均延迟吗？

预期的输出是："latency": 16.2, "requests_per_second": 4.33

Answer 1

您没有提供预期的输出，所以您的问题不清楚，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

根据您在问题中添加的预期输出进行更新：

$ 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
