PROBLEM:

When we go to Grafana UI:

Under HBase - Tables:

1. NUM FLUSHES

2. NUM WRITE REQUESTS

3. NUM READ REQUESTS

Under HBase - Users:

1. Num Get Requests

2. Num Scan Next Requests

We just see:

Problem! java.lang.Exception: Invalid number of functions specified.

grafana.log show:

[I] Completed X.X.X.X - "GET /ws/v1/timeline/metrics HTTP/1.1" 400 Bad Request 144 bytes in 7653us
[I] Completed X.X.X.X - "GET /ws/v1/timeline/metrics HTTP/1.1" 400 Bad Request 144 bytes in 3316us
[I] Completed X.X.X.X - "GET /ws/v1/timeline/metrics HTTP/1.1" 400 Bad Request 144 bytes in 1734us

RESOLUTION:

1. Login with Grafana admin.

2. Set transform=none in panels.
