Usage

log4jp <log-file> [query]

Query

The query filters the events that will displayed.

A query contains:

• keywords
• event properties
• regular expressions

Keyword Query

The keyword query is by default case insensitive, unless ... is specified.

When multiple separate keywords are present in query, the query selects the union of events that contain each keyword.

blue red

will return all events that contain "blue" and all events that contain "red". Those events that contain both "blue" and "red" will be represented once in the returned set.

Note that

blue red

and

"blue red"

are different.

Keywords are matched against each property.

Event Property Query

Event property values can be queried using the following syntax:

property-name:query
