我如何阅读/了解目标主机上的Ansible日志(由syslog编写) [英] How do I read / understand ansible logs on target host (written by syslog)

问题描述

在某个主机上执行ansible时，它将在该主机上写入syslog，如下所示:

When you execute ansible on some host, it will write to syslog on that host, something like this:

Dec  1 15:00:22 run-tools python: ansible-<stdin> Invoked with partial=False links=None copy_links=None perms=None owner=False rsync_path=None dest_port=22 _local_rsync_path=rsync group=False existing_only=False archive=True _substitute_controller=False verify_host=False dirs=False private_key=None dest= compress=True rsync_timeout=0 rsync_opts=None set_remote_user=True recursive=None src=/etc/ansible/repo/external/golive/ checksum=False times=None mode=push ssh_args=None delete=False

Dec  1 15:20:03 run-tools python: ansible-<stdin> Invoked with warn=True executable=None _uses_shell=False _raw_params=visudo -c removes=None creates=None chdir=None 

这些日志是否有任何文档或说明可以帮助我理解如何阅读它们?具体来说，我希望能够看到ansible做了什么，它触摸了哪些文件，等等.可以在那里找到它吗?还是重新配置ansible，以便它在其中写入此类信息?

Is there any documentation or explanation of these logs that would help me understand how to read them? Specifically I would like to be able to see what exactly ansible did, which files it touched etc. Is it possible to find it there? Or reconfigure ansible so that it writes this kind of information in there?

是否可以完全配置这些​​日志?怎么样?

Is it possible to configure these logs at all? How?

推荐答案

我不知道专门解释syslog消息内容的文档.但是，您可以在

I am not aware of documentation that explains the contents of syslog messages specifically. However, you can look at some of the logging code in AnsibleModule.log() to see what's going on. Basically, it's reporting module names and the parameters they were called with.

对于配置日志，针对

For configuring logs, there are some good suggestions in response to this related question. The summary is that you can get more information - including your request about what ansible did - by specifying a log path and running with the verbose -v flag. For more fine-grained control, you can attack the problem from two different angles:

• 在剧本方面，您可以使用 debug 模块或根据您的需要量身定制更改/失败的结果.这两个更改都可以为您的日志输出添加有用的上下文.

• From the playbook side, you can use the debug module or tailor your handling of changed/failed results to suit your needs. Both of those changes can add useful context to your log output.

在剧本之外，您可以使用Ansible 回调插件来控制日志记录. 此处是一个回调插件的示例，该插件拦截日志并输出更易读的内容. p>

Outside of playbooks, you can use Ansible callback plugins to control logging. Here is an example of a callback plugin which intercepts logs and outputs something more human readable.
