`memtrack.enabled` `boolean`

- Disables or enables the extension. Default value is 0, i.e. disabled.

`memtrack.soft_limit` `int`

- 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_limit` `int`

- 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_limit` `int`

- 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_functions` `string`

- 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.
