Procedure for All Errors

The AXIS shelf controller (ASC) maintains a set of log files, which contain the messages logged by the ASC and the individual service modules. The logs are stored on the ASC hard disk. There are five logs, each log contains the events for one day. The logs are rotated daily, therefore there should always be events for five days. Each log file contains information about configuration changes and errors that occurred in the shelf on a particular day. The commands used by the user to change the configuration are also logged in these log files.

Note Each file has a maximum size of 1.4 MB. When a day’s log exceeds 1.4 MB, the last entry in the log is overwritten each time a new message is logged. This process is repeated until a new file is created the next day.

The log file can be displayed only from the command-line interface (CLI). The CLI command used to display the log is dsplog.

dsplog (slot#) (slot# day offset)

The day offset means offset from today.

Examples: dsplog 7 1 would display the events for slot 7 that occurred yesterday. dsplog 12 3 would display the events for slot 12, 3 days ago. dsplog 5 would display the events for slot 5 today.

dsplog displays all the logs starting from the most current and proceeding backwards.

Each line of the log display is one log entry in the following fixed format:

Displayed Log Message Format

The messages logged are displayed in the following syntax:

<Date>-<Time> <Slot Number> <Task Name/User Id> <Log Code> <Log String> : <Log Specific information>

Date

The date on which this message was logged.

Time

The time at which this message was logged.

Slot Number

The slot number of the card that logged this message.

Task Name/User Id

Name of the task that logged this message, or if it is command log then

 

specifies the user ID.

Log Code

Numeric value that specifies the log code.

Log String

The log string associated with the log code.

Log Specific information

Addtional information on the specific instance of this log.

 

For example, if a line is in LOS, the line number is displayed.
