Here's a short explanation of
the configuration directives.
memtrack.enabledboolean
Disables or enables the extension. Default value is 0, i.e. disabled.
memtrack.soft_limitint
Soft memory limit.
The extension checks memory consumption before and after executing an
op_array and produces a warning is the difference between the two values
is equal to or greater than the soft limit, but only if the function is not
ignored.
Setting this option to 0 also disables both soft and hard limit warnings.
Default value is 0, i.e. no warnings is produced.
memtrack.hard_limitint
Hard memory limit.
The extension checks memory consumption before and after executing an
op_array and produces a warning is the difference between the two values
is equal to or greater than the hard limit, even if the function is
ignored.
Setting this option to 0 disables hard limit warnings completely.
Default value is 0, i.e. no hard limit warnings is produced.
memtrack.vm_limitint
Virtual memory limit (set on a process).
This limit is checked only on shutdown and a warning is produced if the
value is greater than or equal to the limit.
This option is currently supported only on OSes where mallinfo() function
is available (i.e. Linux).
memtrack.ignore_functionsstring
A comma or whitespace-separated list of functions which are to be ignored
by soft_limit. The values are case-insensitive, for class methods use
class::method syntax.
