Troubleshooting IDM
Using Decision Manager Tracing
Using Decision Manager Tracing
IDM provides a tracing tool (
DMConfig.prp
) and log file (
DM-IDMDM.log
) to assist
with troubleshooting IDM problems that may occur. These files are included
on the IDM Agent when it is installed on the RADIUS server. Note that the
Decision Manager (DM) is an internal component of the IDM Agent.
The default configuration has the tracing options turned off because of the
performance degradation when tracing is used.
To turn on tracing, edit the DMConfig.prp file on the RADIUS server. The default
directory location is
\Program Files\Hewlett-Packard\PNM\agent\logs.
Available logging options in DMConfig.prp are:
Log_dm_cache = true/false: True will log IDM configuration deployment
events, including the configuration file data content. The default setting is
false, IDM configuration deployment logging is turned off.
Log_radius_requests = true/false: True will log RADIUS requests and the
IDM agent response to RADIUS. If the request is accepted then it also logs the
access policy group, policy rule and access profile that is sent to RADIUS.
The default setting is false, RADIUS requests are not logged.
Log_radius_acc_events = true/false: True will log session accounting
events, such as session start and stop. The default setting is false, session
events are not logged.
When logging is turned on, data is sent to the DM-IDMDM.log file. The default
directory location is
\Program Files\Hewlett-Packard\PNM\agent\logs.
Use this file for tracing purposes, to capture the following information:
■ What RADIUS requests are received and the IDM agent response to
the request, including the time (in milliseconds) it took the IDM agent
to serve the RADIUS request.
■ A list of accounting events (like session start/stop) being sent by
RADIUS to the IDM agent, and whether or not the IDM agent could
post them properly to the IDM server.
■ Configuration deployments to the IDM Agent, along with the actual
configuration image.
