The web interface to Ganglia fails to work after I boot because gmetad isn't starting. master2:~ # ps aux |grep gmond nobody 3747 0.1 0.0 23716 2404 ?

Which should start first? Does it matter? What happens if gmetad starts before gmond? The documentation shows that gmond is started first but it doesn't list any specific start order dependencies. master2:~ # cd /etc/rc.d master2:/etc/rc.d # find . -name \*gmetad\* ./rc3.d/S10gmetad ./rc3.d/K12gmetad ./rc5.d/S10gmetad ./rc5.d/K12gmetad ./gmetad master2:/etc/rc.d # find . -name \*gmond\* ./rc3.d/S10gmond ./rc3.d/K12gmond ./rc5.d/S10gmond ./rc5.d/K12gmond ./gmond So, based on this and how init.d works, with my configuration, it will try to start gmetad before gmond. I get this error: There was an error collecting ganglia data (127.0.0.1:8652): fsockopen error: Connection refused ... until gmetad is started manually. This makes sense, since the web interface gathers data from gmetad, but I don't know why my configuration is saying the service is starting when it really isn't. Does gmetad terminate if gmond hasn't started yet? Any clues?
