Hi Dan I can see a couple of things that could be wrong (NB: not a collectd expert, but these are differences I see from my working config).
1. Is /opt/collectd/etc/collectd.conf your main collectd config file? otherwise, it's not being read at all by collectd. 2. I configure the plugin in that file i.e. the <Module "mesos-master"> block should be in /opt/collectd/etc/collectd.conf , not tucked down in the python module path directory. 3. Are you sure your master listens on localhost? Mine doesn't, I needed to set that Host line to match the IP I set that master to listen on ( e.g. in /etc/mesos-master/ip ). Pretty sure one of those will do the trick (NB: you'll only get metrics from the elected master; the 'standby' masters still get polled but collectd will ignore any data from them unless they're the primary) On 11 March 2015 at 19:52, Dan Dong <[email protected]> wrote: > Hi, Dick, > I put the plugin under: > $ ls -l /opt/collectd/lib/collectd/plugins/python/ > total 504 > -rw-r--r-- 1 root root 345 Mar 10 19:40 mesos-master.conf > -rw-r--r-- 1 root root 11111 Mar 10 15:06 mesos-master.py > -rw-r--r-- 1 root root 322 Mar 10 19:44 mesos-slave.conf > -rw-r--r-- 1 root root 6808 Mar 10 15:06 mesos-slave.py > -rw-r--r-- 1 root root 288892 Mar 10 19:35 python.a > -rwxr-xr-x 1 root root 969 Mar 10 19:35 python.la > -rwxr-xr-x 1 root root 188262 Mar 10 19:35 python.so > > And in /opt/collectd/etc/collectd.conf, I set: > > <LoadPlugin python> > Globals true > </LoadPlugin> > ..... > > <Plugin python> > ModulePath "/opt/collectd/lib/collectd/plugins/python/" > LogTraces true > </Plugin> > > $ cat /opt/collectd/lib/collectd/plugins/python/mesos-master.conf > <LoadPlugin "python"> > Globals true > </LoadPlugin> > > <Plugin "python"> > ModulePath "/opt/collectd/lib/collectd/plugins/python/" > Import "mesos-master" > <Module "mesos-master"> > Host "localhost" > Port 5050 > Verbose false > Version "0.21.0" > </Module> > </Plugin> > > Anything wrong with the above settings? > > Cheers, > Dan > > > > 2015-03-10 17:21 GMT-05:00 Dick Davies <[email protected]>: > >> Hi Dan >> >> The .py files (the plugin) live in the collectd python path, >> it sounds like maybe you're not loading the plugin .conf file into >> your collectd config? >> >> The output will depend on what your collectd is set to write to, I use >> it with write_graphite. >> >> On 10 March 2015 at 20:41, Dan Dong <[email protected]> wrote: >> > Hi, All, >> > Does anybody use this mesos-collectd-plugin: >> > https://github.com/rayrod2030/collectd-mesos >> > >> > I have installed collectd and this plugin, then configured it as >> > instructions and restarted the collectd daemon, why seems nothing >> > happens on >> > the mesos:5050 web UI( python plugin has been turned on in >> > collectd.conf). >> > >> > My question is: >> > 1.
