Hi,
I am developing a ceph  plugin based on some code at github(https://github.com/ceph/collectd),but I encounter a problem:
In my case, my code will create 3 rrd files  named mon1.rrd,osd2.rrd,mds.rrd, the number of DS in each rrd file respectively is:
[2014-01-09 15:27:25] [debug] plugin_register_data_set(osd2): d->dset.ds_num=305
[2014-01-09 15:27:25] [debug] plugin_register_data_set(mon1): d->dset.ds_num=61
[2014-01-09 15:27:25] [debug] plugin_register_data_set(mds): d->dset.ds_num=165

Actually, collectd does not work as expected and only create mon1.rrd, I do not know if this is related to my large amount of DS at osd2.rrd and mds.rrd, does collectd have any limitations?
I have collectd worked under debug mode, but  I don't see any error log except a INFO like this:
[2014-01-09 15:27:25] [info] Filter subsystem: Built-in target `write': Dispatching value to all write plugins failed with status -1

I am not sure if this is related to my problem.

any help there would be appreciated!

Best Regards,
Dennis
