7.1. Log Files

Virtually every troubleshooting step should start with a look at the associated log file or files. These
provide invaluable information about the activity that has taken place on the device or within the
application that can be used to monitor performance and ensure proper configuration. See Table 7-1
for the paths to all relevant log files:
Component/Task
Apache HTTP Server
RHN Satellite Server
RHN Satellite Server Installation Program
Database installation - Embedded Database
Database population
RHN Satellite Synchronization Tool
Monitoring infrastructure
Monitoring notifications
RHN DB Control - Embedded Database
RHN Task Engine (taskomatic)
Red Hat Update Agent
XML-RPC transactions

7.2. General Problems

To begin troubleshooting general problems, examine the log file or files related to the component
exhibiting failures. A useful exercise is to tail all log files and then run
then examine all new log entries for potential clues.
A common issue is full disk space. An almost sure sign of this is the appearance of halted writing
in the log files. If logging stopped during a write, such as mid-word, you likely have filled disks. To
confirm this, run this command and check the percentages in the Use% column:
