IRIS

Intelligent Roadway Information System

Troubleshooting

Events

Many events are stored in the database, and can be used for troubleshooting.

Error Logs

Serious system errors are written to stderr, which is redirected to a file at /var/log/iris/iris.stderr. Check this file first when any problems are suspected.

XML Output

There are a number of XML files which are written by the IRIS server periodically. These files contain configuration information about the system as well as realtime data concerning the current state. These files are stored in the /var/www/html/iris_xml/ directory.

Filename	Period	Description
`tms_config.xml.gz`	24 hours	Configuration data for IRIS system. If the district server property is changed, the filename will be changed to match `{district}_config.xml.gz`
`det_sample.xml.gz`	30 seconds	Sample data from vehicle detection systems
`stat_sample.xml.gz`	30 seconds	Mainline station data from vehicle detection systems
`incident.xml.gz`	30 seconds	Current incident information
`sign_message.xml.gz`	30 seconds	Current DMS sign message information

Debug Trace Logs

There are a number of debugging logs which can be enabled in the /var/log/iris directory. To enable a particular log, use the touch command to create a file with the proper name. Some of these logs can grow very large, so be sure to have enough disk space available.
