Golang package for writing monitoring check plugins for nagios, icinga2, zabbix, checkmk, etc.
The package complies with the Monitoring Plugins Development Guidelines.

// response.SetOutputDelimiter(" / ")
// Updating check plugin status and adding message to the output (status only
// changes if the new status is worse than the current one).
// check status stays ok
response.UpdateStatus(monitoringplugin.OK, "something is ok!")
// check status updates to critical
response.UpdateStatus(monitoringplugin.CRITICAL,
"something else is critical!")
// check status stays critical, but message will be added to the output
response.UpdateStatus(monitoringplugin.WARNING, "something else is warning!")
