Measures reported by DTMemUsageTest

When the Double-Take service starts, it reserves a pool of user-addressable memory equal to the Double-Take pagefile size. This reserved pool of memory is the Double-Take pagefile. Although Double-Take has the pool of memory reserved, it only uses what is necessary at any given time.

This test reports the amount of memory in the reserved memory pool that the Double-Take server currently uses, and thus enables you to track the memory usage of the Double-Take server.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Memory_Allocated Indicates the amount of memory from the reserved memory pool that is currently allocated to the mirroring and/or replication operations of the Double-Take server being monitored. MB A very high value could indicate that the the server functions are over-utilizing the memory resources available to them.

In order to provide maximum Double-Take system performance, Double-Take servers should be configured with enough RAM to accommodate the maximum Double-Take pagefile (1GB) in addition to the server's other memory needs.
