Overview

This proposal is to add additional memory statistics to the SiteInformation schema.

Motivation

When running stress tests on the server or just quering the current state of the server it would be nice to know the current working set memory and the virtual memory being used by the server.

Proposed Solution

A new SiteInformation schema will be added with the following new statistics:

WorkingSet - The working set memory of the MapGuide server in bytes.
VirtualMemory - The virtual memory of the MapGuide server in bytes.

The new SiteInformation schema version will be SiteInformation-2.2.0.xsd

Implications

This is new schema only. There will be no effect on existing applications. However, in order to get the new schema you must use the new version when doing the request.

Test Plan

Check that new schema returns new information.

Addendum, Oct. 28, 2009

Updated schemas to support multiple servers in a site.

Addendum, Dec. 9, 2009

Added the following additional statistics to the schema:

CacheSize - The current number of entries in the MapGuide server cache.
CacheDroppedEntries - The total number of entries in the MapGuide server cache that have been dropped.
