流媒体
例如，可以从尾随日志将数据导入到eliot树中，并且 让它逐渐呈现出来。但是有一个警告：树只是 一次呈现结束消息-树根的成功或失败状态 操作出现在数据中。
来自python的用法
importjson,sysfromeliottreeimporttasks_from_iterable,render_tasks# Or `codecs.getwriter('utf-8')(sys.stdout).write` on Python 2.render_tasks(sys.stdout.write,tasks,colorize=True)
请参阅help(render_tasks)和help(tasks_from_iterable)来自
python repl了解更多信息。
从命令行使用
$ eliot-tree
usage: eliot-tree [-h] [-u UUID] [-i KEY] [--raw]
[--color {always,auto,never}] [--no-colorize] [-l LENGTH]
[--select QUERY] [--start START] [--end END]
[FILE [FILE ...]]
Display an Eliot log as a tree of tasks.
positional arguments:
FILE Files to process. Omit to read from stdin.
optional arguments:
-h, --help show this help message and exit
-u UUID, --task-uuid UUID
Select a specific task by UUID
-i KEY, --ignore-task-key KEY
Ignore a task key, use multiple times to ignore
multiple keys. Defaults to ignoring most Eliot
standard keys.
--raw Do not format some task values (such as UTC
timestamps) as human-readable
--color {always,auto,never}
Color the output. Defaults based on whether the output
is a TTY.
-l LENGTH, --field-limit LENGTH
Limit the length of field values to LENGTH or a
newline, whichever comes first. Use a length of 0 to
output the complete value.
--select QUERY Select tasks to be displayed based on a jmespath
query, can be specified multiple times to mimic
logical AND. If any child task is selected the entire
top-level task is selected. See <http://jmespath.org/>
--start START Select tasks whose timestamp occurs after (or on) an
ISO8601 date.
--end END Select tasks whose timestamp occurs before an ISO8601
date.
