RedisMQ Dashboard

1. Navigate to MQ monitoring on the left pane in the Rakuten Sixthsense portal.
2. Select Redis from the Message queue drop-down.
3. Select a service from the Service name drop-down list as in the following screen.

A screen similar to the following is displayed.

The top pane displays the following metrics and you can view total number of the various Redis concepts at a glance.

note

The above metrics calculate changes over time

• DIFF - Shows the difference between two collection intervals
• RATE - Measures per-second change (e.g., CPU percentage)
