Retrieving configurations

This tech note describes how you can retrieve configuration files from IP Fabric’s configuration management capability, to be consumed outside the platform.

You do this in two stages:

send a POST to /tables/management/configuration with a request body like
```
{
  "columns":["id", "hash", "hostname", "lastChangeAt", "lastCheckAt", "reason", "sn", "status"]
}
```
You can of course filter that list (for example for devices containing L36) with a key:value pair.
```
"filters": {
  "hostname": ["like","L36"]
}
```
Or you can select the range of dates you are interested in:
```
"filters": {
  "lastCheckAt": ["gte",XXXXXXXXXXXXXX]
}
```
where XXXXXXXXXXXXXX is the UNIX epoch time representing the start of the time range.

This gives you the list of saved configurations, and most importantly, the "hash" for each.
send a GET to /tables/management/configuration/download?hash=XXXXXXXXXXXXX where XXXXXXXXXXXXX is the hash for the required config from the list returned in step 1. This returns the plain text of the configuration in question.
