Subject: [PATCH v2 0/2] trace-cmd: SQL-like syntax for ftrace histograms configuration
Date: Wed, 19 Feb 2020 15:15:21 +0200 [thread overview]
Message-ID: <20200219131523.447352-1-tz.stoyanov@gmail.com> (raw)
Configuration of complex ftrace histograms could be hard, using the existing ftrace interface.
The "--sql" option is implemented to simplify this task. It uses a sql-like syntax to define
the histograms and generates necessary ftrace syntetic events and triggers. Each ftrace event
represents a sql tible, while the fields of this event are rows in the table.
[
v2 changes:
- Removed patches for trace-cmd reset sub command from this patch set, as
they are not directly related to the SQL-like syntax implementation.
- Fixed the use case with more than one "--sql" argument. Added logic to
clean up the parser state before parsing a new string.
- Implemented API for freeing all resources, allocated by the parser.
- Fixed the use case with ftrace instances.
]
