Monitoring Elasticsearch

APIs

Elasticsearch の様子を知るのに便利な様々な API がある。
これらを参照する Elasticsearch プラグインや各種モニタリングツール (mackerel, munin, etc.) のプラグインが開発されている。
API 間で重複する内容があったり、似ているようで異なるものがあったりするので使い分けに注意。

	$ brew install go
	==> Downloading https://downloads.sf.net/project/machomebrew/Bottles/go-1.2.2.mavericks.bottle.tar.gz
	######################################################################## 100.0%
	==> Pouring go-1.2.2.mavericks.bottle.tar.gz
	==> Caveats
	As of go 1.2, a valid GOPATH is required to use the `go get` command:
	http://golang.org/doc/code.html#GOPATH

	`go vet` and `go doc` are now part of the go.tools sub repo:
	http://golang.org/doc/go1.2#go_tools_godoc

	```
	$ brew install postgres
	==> Installing postgresql dependency: ossp-uuid
	==> Downloading https://downloads.sf.net/project/machomebrew/Bottles/ossp-uuid-1.6.2.mavericks.bottle.1.tar.gz
	######################################################################## 100.0%
	==> Pouring ossp-uuid-1.6.2.mavericks.bottle.1.tar.gz
	==> Caveats
	This formula is keg-only, so it was not symlinked into /usr/local.

	OS X provides a uuid.h which conflicts with ossp-uuid's header.

	$ brew install redis
	==> Downloading https://downloads.sf.net/project/machomebrew/Bottles/redis-2.8.11.mavericks.bottle.tar.gz
	######################################################################## 100.0%
	==> Pouring redis-2.8.11.mavericks.bottle.tar.gz
	==> Caveats
	To have launchd start redis at login:
	ln -sfv /usr/local/opt/redis/*.plist ~/Library/LaunchAgents
	Then to load redis now:
	launchctl load ~/Library/LaunchAgents/homebrew.mxcl.redis.plist
	Or, if you don't want/need launchctl, you can just run:

	$ brew install tuntap
	==> Downloading https://homebrew.bintray.com/bottles/tuntap-20111101.mavericks.bottle.tar.gz
	######################################################################## 100.0%
	==> Pouring tuntap-20111101.mavericks.bottle.tar.gz
	==> Caveats
	In order for TUN/TAP network devices to work, the tun/tap kernel extensions
	must be installed by the root user:

	sudo cp -pR /usr/local/Cellar/tuntap/20111101/Library/Extensions/tap.kext /Library/Extensions/
	sudo cp -pR /usr/local/Cellar/tuntap/20111101/Library/Extensions/tun.kext /Library/Extensions/
