CheckMem

This check checks the memory (page) usage and generates a state if the memory is above or below give parameters.

Option	Values	Description
MaxWarn	size-value or %	The maximum size allowed before a warning state is returned.
MaxCrit	size-value or %	The maximum size allowed before a critical state is returned.
MinWarn	size-value or %	The minimum size allowed before a warning state is returned.
MinCrit	size-value or %	The minimum size allowed before a critical state is returned.
ShowAll	None, long	Add this option to show info even if no errors are detected. Set it to long to show detailed information.
type	page, paged, virtual, physical	What kind of memory to check (does not yet support stacking to check multiple kinds)

The size-value or % is a normal numeric-value with an optional unit or percentage postfix to specify large sizes. The available postfixes are B for Byte, K for Kilobyte, M for Megabyte, G for Gigabyte and finally % for percent free space.

What the different types really mean

Type	Meaning
page	Number of .. ?? This is the commitlimit (same as used in NSCLient, ie. via PDH, available on NT4)
paged	Number of .. ?? (Usually identical to 'page', different APIs for I think the same thing) According to M$ this is: Size of available memory to commit, in bytes.
virtual	Number of pages of swap currently in use (note - it does NOT = (physical + swap) as on *nix boxes) According to M$ this is: Size of unreserved and uncommitted memory in the user mode portion of the virtual address space of the calling process, in bytes.
physical	Total amount of RAM in the server ?? (does it change?) According to M$ this is: Total size of physical memory, in bytes.

Examples

Check that the page is below 80%:

 checkMem MaxWarn=80% MaxCrit=90% ShowAll type=page
 OK: page: 758M (795205632B)|page=30% 80%;90%;

Check that the physical is below 80%:

 checkMem MaxWarn=80% MaxCrit=90% ShowAll type=physical 
 OK: physical: 758M (795205632B)|'physical memory'=30% 80%;90%;
