Check system load average.
check-load -w 4,3,2 -c 3,2,1
First, build this program.
go get github.com/mackerelio/go-check-plugins
cd $(go env GOPATH)/src/github.com/mackerelio/go-check-plugins/check-load
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-load -w 4,3,2 -c 3,2,1
If there are no problems in the execution result, add a setting in mackerel-agent.conf .
[plugin.checks.check-load-sample]
command = ["check-load", "-w", "4,3,2", "-c", "3,2,1"]
-w, --warning=WL1,WL5,WL15 Warning threshold for loadavg1,5,15
-c, --critical=CL1,CL5,CL15 Critical threshold for loadavg1,5,15
-r, --percpu Divide the load averages by cpu count
Please execute check-load -h
and you can get command line options.
