8 Troubleshooting

8.1 Check the Linux machine has been prepared correctly

The most common issues are a direct result of Linux machine misconfiguration, mainly around

networking, NTP timeserver configuration or Windows domain membership. Fixing the Linux

machine’s configuration will often resolve issues with the VDA software.

8.2 Configure logging and tracing

The method for enabling logging (and tracing) differs between the Broker Agent and the HDX

Service.

8.2.1 Broker Agent logging

The Broker Agent (also known as the ctxvda service) writes log data to:

/var/log/xdl/vda.log

Tail the content of this file using:

tail -f /var/log/xdl/vda.log

The Broker Agent will roll the log file over at 10MB, archiving it to a gzip compressed file in the

same directory. These files have the format:

vda.log.N.gz

Where N is 1 to 10. To conserve disk space, only the last 10 archived log files are retained. To view

an archived log file decompress the file using gunzip or display directly with zcat or zmore.

8.2.2 HDX Service tracing

Unlike the Broker Agent, the HDX Service does not trace or log anything by default. If tracing is

required, a separate script provided in the installation package will self-extract the tools required.

Copy xdl-trace-install.sh from the installation package onto the Linux VDA machine, preferably in

your home directory. Make it executable and run it:

chmod 755 xdl-trace-install.sh

./xdl-trace-install.sh

This extracts the setd/jointfilesconvert/397668/bg UI application and configuration file into your ~/bin directory. Run the

application to set logging and tracing options:

~/bin/setd/jointfilesconvert/397668/bg

The HDX service writes trace log data to:

/var/log/xdl/hdx.log

Tail the content of this file using:

tail -f /var/log/xdl/hdx.log
