Shepherd Component Exit Codes

A guide for devs

The following is a list of recommended exit codes for grabbers. The only compulsory part (at the moment) is that components exit with 0 to signal success: if they do, Shepherd will parse their output; if they don't, Shepherd will ignore their output and flag the component as having failed.

All other codes are optional, but it might be useful if components use a common system.

Exit Code	Meaning
0	Success
Non-zero	Failure
10	No network
11-19	Other network-related failure
20	Unable to parse anything from data source
21-29	Other parsing-related failure
30	Component requires configuration
31	Component requires re-configuration
32-39	Other failure requiring user intervention
