Overview¶
What is Gadget?¶
Gadget is a mechanism intended to improve the speed of investigating bugs from post-mortem logs.
Gadget operates by embedding specifically-marked log lines which can later be parsed. Log lines indicate important events in your flow, which you may be interested in finding later.
There are several types of events:
- Operation: indicates that some action happened to or on some entity. It must contain the name of the entity and the name of the operation, and may contain other arbitrary parameters
- Update: Indicates that a certain entity has been updated. It must contain the update data (but not necessarily the new state)
- State: Indicates a new state for a given entity
What is gadget-python?¶
gadget-python is the Python library used to emit Gadget-targeted log lines and parse them.
