On Ubuntu, Upstart log messages are typically stored in the
/var/log/upstart file. This file contains a record of all events and actions performed by the Upstart daemon, including starting and stopping services, running scripts, and other actions.
To view the Upstart log messages on Ubuntu, you can use the
tail command to view the contents of the
/var/log/upstart file in real-time, or you can use the
cat commands to view the contents of the file. You can also use the
grep command to search for specific log messages.
For example, to view the Upstart log messages in real-time, you can use the following command:
tail -f /var/log/upstart
To search for a specific log message, you can use the
grep command, like this:
grep "ssh" /var/log/upstart
This will search the Upstart log for any lines containing the string “ssh”, which will include any log messages related to the
Here are a few more things you might want to know about Upstart log messages on Ubuntu:
- Upstart log messages are generated in the following format:
timestamp init: process (process-id): log message
For example, a log message indicating that the
ssh service has been started might look like this:
Jan 1 12:34:56 hostname init: Starting ssh service...
- You can customize the logging behavior of Upstart services by modifying the
logstanza in the Upstart configuration file for the service. For example, you can specify the location of the log file, the level of detail included in the log messages, and other options.
- To view the Upstart log messages for a specific service, you can use the
initctlcommand to query the status of the service and view the log messages for that service. For example, to view the log messages for the
sshservice, you can use the following command:
initctl status ssh
This will display the current status of the
ssh service, as well as any log messages associated with the service.
- Upstart log messages can be useful for troubleshooting problems with services on your Ubuntu system. If a service is not starting or is behaving unexpectedly, examining the Upstart log messages can help you understand what is happening and identify the root cause of the problem.
