Fields
The system journal contains entries with information (binary data) stored in fields with specific meaning. When you run the
svc_journalctl script, in addition to the optional arguments described above, you can choose to filter the information you
want to see based on these fields or based on the value these fields contain. For example:
● The following command establishes a basic field matching query to view log messages associated with the Platform
component, with a marker value of NDU, and have a message priority level of ERROR:
svc_journalctl COMPONENT=Platform MARKER=NDU PRIORITY=ERROR
● The following command enables you to search for a specific case-sensitive text pattern in the log messages associated with
the Platform component:
svc_journalctl -g --case-sensitive=TRUE CONTEXT=456abc COMPONENT=Platform
For more information about the journal fields, see System Journal Fields on page 77.
Output Format
When you run the script, the output appears in a set order of default fields. The following is a sample of the default output from
the script:
