cpu_poll_interval = 0.25

env:CGROUP_CPU_POLL_INTERVAL

[callback_cgroup_perf_recap]
file_name_format = %(feature)s.%(ext)s

env:CGROUP_FILE_NAME_FORMAT

Format of filename. Accepts %(counters), %(task_uuids), %(features), %(exts). Defaults to %(features.%(ext)s) when file_per_task is False and %(counters-%(task_uuid)s-%(feature)s.%(ext)s) when True

boolean

"/tmp/ansible-perf-%s"

ini entries:

[callback_cgroup_perf_recap]
output_dir = /tmp/ansible-perf-%s

env:CGROUP_OUTPUT_DIR

Output directory for files containing recorded performance readings. If the value contains a single %s, the start time of the playbook run will be inserted in that space. Only the deepest level directory will be created if it does not exist, parent directories will not be created.

Interval between PID polling for determining PID count. A lower value may produce inaccurate results, a higher value may not be short enough to collect results for short tasks.

boolean

ini entries:

[callback_cgroup_perf_recap]
write_files = no

env:CGROUP_WRITE_FILES

Dictates whether files will be written containing performance readings
