The Performance Monitor is available only to network engines with a Windows Embedded OS. Start the Performance Monitor from the NCT Tools tab. See Tools tab for more information. When you click Performance Monitor, the Performance Monitor screen appears (Figure 1).

Important: When the NCT Performance Monitor is running, it places additional load on the processor. If the processor is close to being overloaded, this additional load may cause the to reset.
Note: The NCT must be connected to a network engine to start and run the Performance Monitor.

Note: Shaded callouts signify features that vary based on the engine in use. Features are described in the following table.

Item Name

User Action, Item Function, and Item Description

1

Processor Usage Indicator

Indicates the percentage of processor time used. Lower values are better for computer performance. If the value climbs to 100% or remains higher than 50 to 75% for more than a few seconds, there is a large load on the network engine processor that you should address.

2

Total Memory Usage Indicator

(NCE25, NAE35, NAE45 Engines Only)

Memory Usage Indicator

(NxE55 Engines Only)

Indicates the percentage of network engine RAM usage. The percentage shown to the right of the indicator bar and the length of the bar represents the percentage of total RAM consumed by the OS, applications, and others. Calculate the actual total amount of RAM by combining the Object Store and the System Memory values shown on the right of the Object Store and System Memory bars.

For example, using the top screen capture shown in Figure 1:

Object Store: 7,144 KB of RAM

System Memory: 107,200 KB of RAM

Total Memory: 114,344 KB of RAM

The percentage fluctuates with usage; however, check for problems if the value increases dramatically. For instance, if the value increases over 50% for no apparent reason and stays there, there may be a problem.

Note: The Total Memory usage indicator is available only when NCT is connected to an NAE35, NAE45, or NCE25 engine. When the NCT is connected to an NxE55 engine, the Memory usage indicator is available. The Memory usage indicator displays the total NxE55 memory available and the amount of memory currently in use.

3

Object Store Usage Indicator

(NCE25, NAE35, NAE45 Engines Only)

Indicates the percentage of RAM that the Windows OS and Metasys system use for temporary storage. The percentage shown to the left of the meter is the portion of total memory reserved for the Object Store. The values shown to the right of the meter indicate how much of the object store is used, its total size, and the percentage used. The total is assigned by the operating system upon startup and remains fixed. The percentage used should not change dramatically after the database has been downloaded. If you see dramatic changes up or down, these file changes may indicate a problem, such as a virus or a hacking attempt.

Note: The Object Store usage indicator is available only when the NCT is connected to an NAE35, NAE45, or NCE25 engine. When the NCT is connected to an NxE55 engine, this indicator is not available.

4

System Memory Usage Indicator

(NCE25, NAE35, NAE45 Engines Only)

Indicates the amount of RAM available to applications after the RAM file system has been allocated.

Note: The System Memory usage indicator is available only when the NCT is connected to an NAE35, NAE45, or NCE25 engine. When the NCT is connected to an NxE55 engine, this indicator is not available.

5

Storage Usage Indicator

Indicates the percent usage of the total storage space available on the flash memory. Storage in the network engine is not like storage in a personal computer. A standard computer has a hard disk drive while the network engine has a flash memory chip. The storage bar displays three values (to the right of the indicator bar): the total amount of storage space on the flash chip available to the network engine, the current amount of flash space used by the network engine (represented by the bar), and the percent usage of the total storage available.

6

Receiving Data Indicator

Indicates integrity of the network engine connection. When blinking, these circles with red dots represent a good connection between the NCT performance monitor and the network engine. If the circles are not blinking, the connection to the network engine may have been lost. If the connection is lost, the data in the performance monitor is no longer dynamic.

Note: Updates to the performance monitor (including the receiving data indicators) may pause during certain operations of the tool, such as receiving a file using the Explorer tab.

7

Always On Top Check Box

Select the Always On Top check box to force the Performance Monitor to remain on top of other applications on the desktop. This selection is recommended, as it is sometimes difficult to get back to this window in time to see transient results.

8

Log Update Interval Value

Select the Log Update interval (in seconds) of the network engine performance data using the up and down arrow buttons.

9

Browse Button

Click Browse to navigate to and select the filepath/folder for storing network engine performance data logs on the NCT computer.

10

Enable Logging Check Box

Select the Enable Logging check box to capture network engine performance data in the selected log file.
