go-perf

Performance mertic 수집 및 ElasticSearch 데이터 전송

Getting Started

Prerequisites

• http://hqgit.inpark.kr/util/go-perf
• golang : go version go1.14.5 windows/amd64

수집기

• psutil : https://github.com/shirou/gopsutil
  • golang 버전 psutil library
  • posix metric 수집 (windows 호환가능)
• performance counter : https://github.com/alexbrainman/pc
  • windows performance counter helper api wrapper

서비스관리

• https://github.com/kardianos/service
  • Service will install / un-install, start / stop, and run a program as a service (daemon)
  • Currently supports Windows XP+, Linux/(systemd | Upstart | SysV), and OSX/Launchd.

Build

go mod tidy 
go build 

Running the tests

Config

• host: ElasticSearch Host
  • If the value is empty, only console output
• index: ElasticSearch Index
• interval: 수집간격(sec)
• sqlinstance: SQLServer Instance Name
  • Windows only, If the value is empty skip

{
	"host": [ "http://localhost:9200", "http://localhost2:9200"],
	"index": "perf",
	"interval": 5,
	"sqlinstance": ""
}

Run Test

$ ./go-perf
