default_protocol = 'file'

class c7n.output.DeltaStats(ctx, config=None)

Bases: object

Capture stats (dictionary of string->integer) as a stack.

Popping the stack automatically creates a delta of the last stack element to the current stats.

class c7n.output.NullStats(ctx, config=None)

Bases: object

Execution statistics/metrics collection.

Encompasses concrete implementations over system stats (memory, cpu, cache size) and api calls.

The api supports stack nested snapshots, with delta consumption to support tracing metadata annotation across nested subsegments.

get_metadata()

Return default of current to last snapshot, without popping.

pop_snapshot()

Remove a snapshot from the snack and return a delta of the current stats to it.

push_snapshot()

Take a snapshot of the system stats and append to the stack.

type = 'default'

class c7n.output.NullTracer(ctx, config=None)

Bases: object

Tracing provides for detailed analytics of a policy execution.

Uses native cloud provider integration (xray, stack driver trace).

subsegment(name)

Create a named subsegment as a context manager

class c7n.output.SystemStats(ctx, config=None)

Bases: c7n.output.DeltaStats

Collect process statistics via psutil as deltas over policy execution.
