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]  db-
       path [-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,
	      completed	and aborted) transactions in the current multi-process
	      session (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,
	      summarize	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 af-
	      ter 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	subdi-
	      rectories.  This is legacy option. For now MDBX handles this au-
	      tomatically  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.
