Logs
Pathfinder Core PRO provides a variety of different logging mechanisms as well as maintaining its own internal
system logs. Click on the Logs link in the Navigation bar to view the current logs in the system as well as to define
logging options.
There are two kinds of log files created by the system. System logs and user logs. System logs are created by the
system’s internal services and primarily define information for use by the developers. You can view these logs by
clicking on the System Logs link.
User logs can be created using the Log Writers link which will be discussed shortly. User logs are where you can
define changes on your Axia network that you want to be entered into log files for later review.
Clicking on any of the logs will open the log for viewing in the browser. The rows for each log also display the file
size and last updated date and time, and finally, a button to delete or clear the log.
You may notice that some logs (such as the one in the screen shot above) have multiple copies with a period and
a number at the end. Due to space restrictions, Pathfinder Core PRO maintains an intelligent log rotation service
which will rotate the log files if they are becoming too large, getting rid of the oldest information. In general,
log files get rotated 4x and the rotation happens when the file size reaches approximately 4MB. There are some
other rules which this service uses that might generate more aggressive log manipulation and/or deletion if space
is becoming limited. For this reason, it is recommended that you use an outside syslog based logging service to
capture logs that you wish to store for longer periods of time. This will be outlined in more detail in the LogWriters
section next.
In order to define logging parameters click on the logs link in the navigation bar and then click on the Log Writers
link on the page that is displayed. This will present a page listing the log writers that have been created in the
system.
Each log writer in the system will be displayed on this page by Name along with its type and location. To create a
new log writer click on the plus icon.
