Terminal dashboard

corium tui opens a full-screen dashboard over one database.

corium tui people --transactor http://127.0.0.1:4334

The dashboard also accepts every connection flag.

The process owns the terminal, so it writes no tracing output.

Navigation

Press Tab to cycle the panels. Press 1 to 4 to jump to one panel, from outside the query editor.

Quit with Ctrl-C anywhere, with q outside the query editor, or with :quit.

Query panel

An editor for EDN Datalog queries, (pull …) forms, and every console command.

Enter runs the form when its brackets balance. Otherwise Enter inserts a newline. Alt-Enter always inserts a newline.

A relation result renders as a scrollable table with :find headers. Every run reports wall-clock time, the datoms scanned, and the basis that it ran against. ↑ and ↓ recall the query history.

Metrics panel

Data-store statistics, sampled from the transactor Status call on the refresh interval:

• Basis, index basis, and index lag.
• Datom, entity, and attribute counts.
• Commit queue depth, transaction totals, and failure rate.
• Indexing and garbage collection counters.
• Lease ownership and the advertised endpoint.

The panel also draws sparklines for transaction frequency, status round-trip latency observed by the peer, and index lag. It reports peer-side query latency as last, average, and maximum.

This panel is the only surface that shows lease ownership without reading the root record directly.

Transactions panel

A live feed from the transaction report subscription of the peer. Each row shows t, the commit time, and the datom count.

A detail pane shows the datoms of the selected transaction. Press f to toggle follow-newest.

Schema panel

The attribute table: ident, value type, cardinality, uniqueness, and the index, component, and history flags.

Press / to filter the table.

When to use the dashboard

Use the dashboard for live observation during a load, a failover test, or an incident. Use the metrics endpoint for recorded monitoring. See monitoring.
