The Sample Properties window provides detailed statistics for time intervals. Each time interval is about one second long. Samples are numbered by the MobiLink Monitor to reflect the order in which they were received.
You can customize the appearance of the graph to hide properties but all properties appear in the Sample Properties window. If you have hidden a property, it is identified as Hidden in the Sample Properties window; otherwise the color is shown.
To open the Sample Properties window, click in the Graph pane for the time period that you want to examine.
The Sample tab provides information for the one-second time interval it represents. The properties that are displayed are for the end of the time interval.
The Range tab shows averages for the entire range of samples that were visible when the properties window was opened (the horizontal range that is visible in the Overview). The range statistics are not calculated until you click Calculate in the Range tab.
Sample Properties contains the following information:
Sample Samples are numbered by the MobiLink Monitor to reflect the order in which they were received. On the Sample tab, this shows the sample number. On the Range tab it shows the range of samples.
Start time and end time On the Sample tab, this reflects a sample time period of approximately one second.
Statistics - Color column The color used in the graph for this property.
Statistics - Property column Shows the queue length for the sample or average queue for the range. This column displays the following types of property:
TCP/IP work queue This lists the number of buffers waiting to be filled by reading from the network plus the number of buffers waiting to be written to the network. The actual number is not very meaningful, but large numbers may indicate network-related bottlenecks.
Stream work queue For version 10 clients only. This queue represents work done by the high-level network layer in the MobiLink server. This layer is responsible for higher-level network protocol work such as HTTP, encryption, and compression.
Heartbeat work queue This is the queue length for periodic internal MobiLink server tasks other than synchronizations.
Command processor work queue This is the queue length for performing database tasks and interpreting or preparing communications with MobiLink clients. The actual number is not very meaningful, but large numbers may indicate database-related bottlenecks.
Busy database worker threads This value indicates how hard the MobiLink server is pushing the consolidated database. Each unit in the value represents a database worker thread that is doing something in the database. There is no distinction between inserts, updates, deletes, or selects. When this value is zero, the server is not operating on the consolidated database.
Note: The names of the properties are obtained from the MobiLink server or .mlm file and are in the language of the MobiLink server. Some characters may not display properly if the MobiLink Monitor is using a different language.
Statistics - Value column The property value.
Statistics - Limit column The maximum allowed value for the property. This is useful so that the graph can use a scale of 0-100% for all properties. For properties such as page faults that are essentially unbounded, the limit is ignored.
