Feature: OSD Overview
Scenario: "Test OSD onode Hits Ratio"
Given the following series:
| metrics | values |
| ceph_bluestore_onode_hits{ceph_daemon="osd.0",instance="ceph:9283",job="ceph"} | 5255 |
| ceph_bluestore_onode_hits{ceph_daemon="osd.1",instance="ceph:9283",job="ceph"} | 5419 |
| ceph_bluestore_onode_hits{ceph_daemon="osd.2",instance="ceph:9283",job="ceph"} | 5242 |
| ceph_bluestore_onode_misses{ceph_daemon="osd.0",instance="ceph:9283",job="ceph"} | 202 |
| ceph_bluestore_onode_misses{ceph_daemon="osd.1",instance="ceph:9283",job="ceph"} | 247 |
| ceph_bluestore_onode_misses{ceph_daemon="osd.2",instance="ceph:9283",job="ceph"} | 234 |
Then Grafana panel `OSD onode Hits Ratio` with legend `EMPTY` shows:
| metrics | values |
| {} | 9.588529429483704E-01 |
