Re: [ceph-users] Ceph monitoring

As someone currently running collectd/influxdb/grafana stack for monitoring, I am curious if anyone has seen issues moving Jewel -> Luminous. I thought I remembered reading that collectd wasn’t working perfectly in Luminous, likely not helped with the MGR daemon. Also thought about trying

Re: [ceph-users] Ceph monitoring

If you take Ceph out of your search string you should find loads of tutorials on setting up the popular collectd/influxdb/grafana stack. Once you've got that in place, the Ceph bit should be fairly easy. There's Ceph collectd plugins out there or you could write your own. On Mon, Oct 2, 2017 at

Hi, I'm reading this document: http://storageconference.us/2017/Presentations/CephObjectStore-slides.pdf I have 3 questions: 1. BlueStore writes both data (to raw block device) and metadata (to RockDB) simultaneously, or sequentially? 2. From my opinion, performance of BlueStore can not
