Available Mbytes 100 Major Available Mbytes shows the amount of physical memory, in megabytes (MB), immediately available for allocation to a process or for system use. It's equal to the sum of memory assigned to the standby (cached), free, and zero page lists. For a full explanation of the memory manager, refer to Microsoft Developer Network (MSDN) or "System Performance and Troubleshooting Guide" in the Windows Server 2003 Resource Kit.

Cache Bytes ---- Major Cache bytes is the current size, in bytes, of the file system cache. By default, the cache uses up to 50% of available physical memory. The counter value is the sum of Memory\System Cache Resident Bytes, Memory\System Driver Resident Bytes, Memory\System Code Resident Bytes, and Memory\Pool Paged Resident Bytes.
Categorization Count ---- Major Categorization Count is the number of categorizations that exist in the mailbox store. Categorizations are created when a user creates a filtered view or performs a search. When the information store must maintain an excessive number of
categorizations, performance can be affected.
Committed Bytes ---- Major Committed Bytes is the amount of committed virtual memory, in bytes. Committed memory is the physical memory that has space reserved on the disk paging files. There can be one or more paging files on each physical drive. This counter displays the last observed value only; it isn't an average.

Severity Description
Committed Bytes in Use ---- Major Committed Bytes in Use is the ratio of Memory\Committed Bytes to the Memory\Commit Limit. Committed memory is the physical memory in use for which space has been reserved in the paging file should it need to be written to disk. The commit limit is determined by the size of the paging file. If the paging file is enlarged, the commit limit
increases, and the ratio is reduced. This counter displays the current percentage value only; it isn't an average.

collection has occurred. When the counter exceeds the threshold, it indicates that CPU is cleaning up and isn't being used efficiently for load. Adding memory to the server would improve this situation. Dumpster delete per sec ---- Major Delete Rate is the rate at which
