| class ForwardServer and relates things are refere Robey Pointer's paramiko example. | |

| output_levels=( | |
| 'status: Status messages, i.e. noting when Fabric is done running, if the user used a keyboard interrupt, or when servers are disconnected from. These messages are almost always relevant and rarely verbose.' | |
| 'aborts: Abort messages. Like status messages, these should really only be turned off when using Fabric as a library, and possibly not even then. Note that even if this output group is turned off, aborts will still occur – there just won’t be any output about why Fabric aborted!' | |
| 'warnings: Warning messages. These are often turned off when one expects a given operation to fail, such as when using grep to test existence of text in a file. If paired with setting env.warn_only to True, this can result in fully silent warnings when remote programs fail. As with aborts, this setting does not control actual warning behavior, only whether warning messages are printed or hidden.' |
In a perfect world, where things are done well, not just quickly, I would expect to find the following when joining the company:
Documentation
Accurate / up-to-date systems architecture diagram
Accurate / up-to-date network diagram
Out-of-hours support plan
Incident management plan
