cat /etc/monit.d/storm

check process storm-nimbus pidfile /var/run/storm/storm-nimbus.pid start programme = "/sbin/service storm-nimbus start" stop programme = "/sbin/service storm-nimbus stop" check process storm-supervisor pidfile /var/run/storm/storm-supervisor.pid start programme = "/sbin/service storm-supervisor start" stop programme = "/sbin/service storm-supervisor stop" check process storm-ui pidfile /var/run/storm/storm-ui.pid start programme = "/sbin/service storm-ui start" stop programme = "/sbin/service storm-ui stop" check process storm-logviewer pidfile /var/run/storm/storm-logviewer.pid start programme = "/sbin/service storm-logviewer start" stop programme = "/sbin/service storm-logviewer stop"
