Hi Nagarrajan,
For graph prototypes you can point your browser to
localhost:41000/perf_graph_prototypes/{perf counter}. In place of perf
counter you can pass osd.op_latency, osd.loadavg, etc. You can find
more of the perf counters at localhost:41000/get_perf_schema/ under
the osd objects. You will be able to find the perf counter and its
description there. These graphs work for the perf counters which give
a time sequence of values.
Also you can view the summary of how these graphs work, and how to
access them, along with their sample snapshots, in the comments of PR
https://github.com/ceph/ceph/pull/16621.
Regards,
Saumay.
