lisa.trace.ComposedCollector

class lisa.trace.ComposedCollector(collectors)

Bases: Mapping

Compose multiple lisa.trace.CollectorBase together.

When used as a context manager, collectors will be nested. Individual collectors can be retrieved by using the instance as a mapping, using the collectors’ NAME attribute as key.

Note

Only one collector of each type is allowed. This allows:

• Getting back the collector instance using a fixed name.

• Some collectors like lisa.trace.DmesgCollector are not re-entrant
