<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal">I am developing a ceph plugin based on some code at github(https://github.com/ceph/collectd),but I encounter a problem:<o:p></o:p></p>
<p class="MsoNormal">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:<o:p></o:p></p>
<p class="MsoNormal"><i>[2014-01-09 15:27:25] [debug] plugin_register_data_set(osd2): d->dset.ds_num=305<o:p></o:p></i></p>
<p class="MsoNormal"><i>[2014-01-09 15:27:25] [debug] plugin_register_data_set(mon1): d->dset.ds_num=61<o:p></o:p></i></p>
<p class="MsoNormal"><i>[2014-01-09 15:27:25] [debug] plugin_register_data_set(mds): d->dset.ds_num=165<o:p></o:p></i></p>
<p class="MsoNormal"><i><o:p> </o:p></i></p>
<p class="MsoNormal">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?<o:p></o:p></p>
<p class="MsoNormal">I have collectd worked under debug mode, but I don’t see any error log except a INFO like this:<o:p></o:p></p>
<p class="MsoNormal"><i>[2014-01-09 15:27:25] [info] Filter subsystem: Built-in target `write': Dispatching value to all write plugins failed with status -1<o:p></o:p></i></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am not sure if this is related to my problem.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">any help there would be appreciated!<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
