MDBX_STAT(1) General Commands Manual MDBX_STAT(1) NAME mdbx_stat - MDBX environment status tool SYNOPSIS mdbx_stat [-V] [-q] [-p] [-e] [-f[f[f]]] [-r[r]] [-a | -s table] dbpath [-n] DESCRIPTION The mdbx_stat utility displays the status of an MDBX environment. OPTIONS -V Write the library version number to the standard output, and exit. -q Be quiet. -p Display overall statistics of page operations of all (running, com- pleted and aborted) transactions in the current multi-process ses- sion (since the first process opened the database after everyone had previously closed it). -e Display information about the database environment. -f Display information about the environment GC. If -ff is given, sum- marize each GC/freelist entry. If -fff is given, display the full list of page IDs in the GC/freelist. -r Display information about the environment reader table. Shows the process ID, thread ID, and transaction ID for each active reader slot. The process ID and transaction ID are in decimal, the thread ID is in hexadecimal. The transaction ID is displayed as "-" if the reader does not currently have a read transaction open. If -rr is given, check for stale entries in the reader table and clear them. The reader table will be printed again after the check is performed. -a Display the status of all of the tables in the environment. -s table Display the status of a specific table. -n Display the status of an MDBX database which does not use subdirec- tories. This is legacy option. For now MDBX handles this automati- cally for existing databases, but may be required while creating new. DIAGNOSTICS Exit status is zero if no errors occur. Errors result in a non-zero exit status and a diagnostic message being written to standard error.
