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, I use rrdtool as my write target and load it, 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
