Telnet Diagnostics Commands

The following Telnet Diagnostics Commands provide visibility to remote Masters, in order to determine the

current state of operations, and are provided as diagnostic/troubleshooting tools.

While these commands are available for any user to execute, their output is interpretable primarily by an AMX

Technical Support Engineer.

Notes on Specific Telnet/Terminal Clients

Telnet and terminal clients will have different behaviors in some situations. This section states some of the

known anomalies.

Windows Client Programs

Anomalies occur when using a Windows™ client if you are not typing standard ASCII characters (i.e. using

the keypad and the ALT key to enter decimal codes). Most programs will allow you to enter specific decimal

codes by holding ALT and using keypad numbers.

For example, hold ALT, hit the keypad 1, then hit keypad 0, then release ALT. The standard line feed code is

entered (decimal 10). Windows will perform an ANSI to OEM conversion on some codes entered this way

because of the way Windows handles languages and code pages.

Refer to the SET SECURITY PROFILE section on page 105 for information on

setting Security Profiles.

Telnet Diagnostics Commands

Command Description

REBOOT HEAP WATCH This command causes the Master to reboot into a Heap Watch mode, where every

memory allocation is tracked back to a task running in the Master.

This option may be useful in cases where a remote Master is indicating a continu-

ous loss of memory. With Heap Watch enabled, AMX Technical Support may be

able to track exactly which task is losing the memory.

SPY

SPY STOP

The SPY and SPY STOP interfaces are provided by VxWorks; AMX has made it

available to the user.

• SPY lists out all of the tasks running in the Master and their CPU usage,

refreshing every 10sec.

• SPY is very similar to a Windows Task Manager output.

This option may be useful in cases where a remote Master seems to be running but

very slowly. Enabling SPY might indicate if a specific task is using up the CPU.

SPY can also be useful in detecting infinite loops in NetLinx or Duet/Java code,

since the Interpreter or Java threads will show that they’re using all of the CPU.

PHYSICAL STATUS This command reports the current state of the Master’s Status, Output and Input

LEDs, in order to troubleshoot a remote Master.

For example, if PHYSICAL STATUS indicates that the Input LED always shows ‘1’

(or ON), it could indicate that the Master is being hammered by incoming events.

MSG STATS This command collects messages statistics for the Interpreter over a 10 second

period by calculating the number of event messages that have been processed.

This can be useful as a debugging/diagnostics tool to determine if the NetLinx Inter-

preter is running and how many messages it’s processing.

It is very important to execute the 'logout' command prior to disconnecting

from a Master. Simply removing the RS-232 connector from the Program Port

maintains your logged-in status until you either return to logout via a new session or

reboot the target Master.
