memory. Information on memory—controlled by garbage collector

memory. Information on memory-controlled by garbage collector

This field is a hash containing information on memory controlled by garbage collector.

*Field*	*Value (in kilobytes)*	*Details*
used	memory used	This number does not include size of housekeeping data used by garbage collector itself.
free	free memory	Free memory is most probably fragmented.
ever_allocated_since_compact	How much memory was allocated since last garbage cleaning, see memory:compact.	This number constantly increases between garbage cleaning procedures. Freeing memory procedures alone do not affect it. It is affected only by garbage cleaning procedures.
ever_allocated_since_start	How much memory was allocated during the whole request processing	This number constantly increases. It is affected by neither garbage cleaning procedures nor freeing memory procedures between them.

Recommended way of analysing
Surround the block to be checked with constructions…

^musage[before XXX]
^musage[after XXX]

…to call this method:

@musage[comment][v;now;prefix;message;line]
$v[$status:memory]
$now[^date::now[]]
$prefix[[^now.sql-string[]] $env:REMOTE_ADDR: $comment]
$message[$v.used $v.free $v.ever_allocated_since_compact $v.ever_allocated_since_start $request:uri]
$line[$prefix $message ^#0A]
^line.save[append;/musage.log]
$result[]

…and analyze the log.

Important notice: while working, Parser takes additional memory blocks from system as required. That is why it is normal when both used and free increase from time to time.

Note: it is not recommended to store log file within web-space.
