6 +rrdrados - Creating, updating and retrieving RRD files from Ceph
10 +E<lt>rrdfileE<gt> = B<ceph//E<lt>nameE<gt>>
15 +This module adds support for creating, updating and retrieving RRD files
16 +directly from a Ceph cluster using librados.
18 +It adds a ceph// prefix to RRD file name which is used to instruct rrdtool to
19 +operate on a file that is stored in Ceph.
21 +Currently the module expects to find the Ceph configuration file in the default
22 +location at /etc/ceph/ceph.conf. By default it uses Ceph client ID "admin" and a
23 +Ceph pool named "rrd".
26 +=head1 ENVIRONMENT VARIABLES
32 +Sets the Ceph Client ID to use when connecting. By default the client ID "admin"
37 +Sets the name of the Ceph Pool to connect to. By default, the pool "rrd" is
