rex — Reth Node Explorer

Use db info for a compact overview of both Reth storage areas.

Command

rex db --datadir ./alice info

Example Output

DATABASE INFO

Datadir:           ./alice
MDBX path:         ./alice/db
Static files path: ./alice/static_files
Schema version:    v2
Schema compatible: yes

MDBX
  Tables:          30
  Non-empty:       10
  Entries:         102
  Table pages:     160.0 KiB
  Freelist pages:  3
  Freelist size:   48.0 KiB
  Data file size:  4.0 GiB

STATIC FILES
  Files:           10
  Logical size:    502 B

Values depend on the selected database and will change as the node imports or unwinds blocks.

Fields

Field	Meaning
Schema version	Value stored in `db/database.version`
Tables	Tables registered by Rex’s pinned Reth schema
Non-empty	Registered tables whose MDBX entry count is greater than zero
Entries	Sum of MDBX entries across registered tables
Table pages	Branch, leaf, and overflow pages currently assigned to registered tables
Freelist	Reusable MDBX pages not currently assigned to table data
Data file size	Logical length of `db/mdbx.dat`; sparse allocation means this is not necessarily physical disk usage
Static files	Number and logical size of regular files below `static_files/`

The table-page total plus freelist size is not expected to equal the MDBX data-file length. MDBX uses a memory-mapped file with reserved address space and reusable pages. Use Database Tables to break the table totals down by name.
