First, build this program.
go get github.com/mackerelio/go-check-plugins
cd $(go env GOPATH)/src/github.com/mackerelio/go-check-plugins/check-elasticsearch
go install
Or you can use this program by installing the official Mackerel package. See Using the official check plugin pack for check monitoring - Mackerel Docs.
Next, you can execute this program :-)
check-elasticsearch --host=127.0.0.1 --port=9200
If there are no problems in the execution result, add a setting in mackerel-agent.conf .
