2.5. Diagnostic Tools

2.5.1. Overview

In the case of a serious system problem cOS Core provides some tools to aid in identifying the

cause. These are:

• Diagnostic CLI commands

• The pcapdump CLI command

Both of these provide output which can be sent to support staff at Clavister to help identify the

circumstances that led to the problem in question.

2.5.2. Diagnostic CLI Commands

The stat CLI Command

If a serious cOS Core problem is suspected then the first step should be to use the CLI command:

Device:/> stat

The stat command will indicate the date and time of the last system shutdown and can indicate if

there has been a serious error in cOS Core operation. It should be remembered however that the

buffer which stat uses is cleared by certain operations such as reconfigure and the output will not

therefore show what occurred prior to buffer clearance.

The dconsole CLI Command

The next step is to use the CLI command:

Device:/> dconsole

This can be abbreviated to:

Device:/> dcon

The dconsole command provides a list of important events that have occurred during cOS Core

operation and can help to establish the date, time and nature of events leading up to a serious

problem occurring. The output might look similar like the following:

Showing diagnose entries since 2008-05-22:

2008-06-21 11:54:58 Start (10.20.02-0:131)

2008-06-21 11:56:16 Stop (RECONFIGURE)

2008-06-21 11:56:21 Start (10.20.02-0:131)

2008-06-21 11:57:29 Stop (RECONFIGURE)

2008-06-21 11:59:31 Start (10.20.02-0:131)

2008-06-21 11:59:49 Stop (NORMAL)

Output from dconsole can include a dump of the system memory in the case of serious runtime

errors. Such a dump will look similar to the following:

Reason: Exception 'DataAbort' occurred at address 0x7aaea34
