The TTL dashboard lets you monitor the progress and performance of from your cluster. To view this dashboard, , click Metrics in the left-hand navigation, and select Dashboard > TTL.

​
Dashboard navigation

Use the Graph menu to display metrics for your entire cluster or for a specific node. To the right of the Graph and Dashboard menus, a time interval selector allows you to filter the view for a predefined or custom time interval. Use the navigation buttons to move to the previous, next, or current time interval. When you select a time interval, the same interval is selected in the pages. However, if you select 10 or 30 minutes, the interval defaults to 1 hour in SQL Activity pages. When viewing graphs, a tooltip will appear at your mouse cursor providing further insight into the data under the mouse cursor. Click anywhere within the graph to pin the tooltip in place, decoupling the tooltip from your mouse movements. Click anywhere within the graph to cause the tooltip to follow your mouse once more. The TTL dashboard displays the following time series graphs:

​
Processing Rate

You can monitor the Processing Rate graph to see how many rows per second are being processed by . TTL processing rate graph

​
Estimated Rows

Monitor the Estimated Rows graph to see approximately how many rows are on the TTL table. TTL estimated rows graph

​
Job Latency

Monitor the Job Latency graph to see the latency of scanning and deleting within your cluster’s . TTL job latency graph

​
Ranges in Progress

Monitor the Ranges in Progress graph to see the number of ranges currently being processed by . TTL ranges in progress graph

​
Summary and events

​
Summary panel

A Summary panel of key metrics is displayed to the right of the timeseries graphs. If you are testing your deployment locally with multiple CockroachDB nodes running on a single machine (this is ), you must explicitly per node in order to display the correct capacity. Otherwise, the machine’s actual disk capacity will be counted as a separate store for each node, thus inflating the computed capacity.

​
Events panel

Underneath the Summary panel, the Events panel lists the 5 most recent events logged for all nodes across the cluster. To list all events, click View all events. DB Console Events The following types of events are listed:
  • Database created
  • Database dropped
  • Table created
  • Table dropped
  • Table altered
  • Index created
  • Index dropped
  • View created
  • View dropped
  • Schema change reversed
  • Schema change finished
  • Node joined
  • Node decommissioned
