Retrieving Device Log File

This page describes how you can retrieve log files for a device from IP Fabric’s discovery to be consumed outside the platform.

Using API

Do this in two stages:

Send a POST to /tables/inventory/devices with a request body like:
```
{
  "columns": ["hostname", "taskKey"],
  "snapshot": "$last"
}
```
You can (and probably would) filter that list (for example, for a specific device with the hostname SWITCH01) by including a key:value pair:
```
"filters": {
  "hostname": ["eq","SWITCH01"]
}
```
This provides you with the task ID for the discovery of the device in question.
Send a GET to /os/logs/task/XXXXXXXXXXXXX, where XXXXXXXXXXXXX is the taskKey value returned in step 1 for the required network device. This returns the plain text of the log file for that device discovery.

Using the python-ipfabric Python SDK this has been simplified to the following.

from ipfabric import IPFClient

ipf = IPFClient()
device = ipf.devices.by_sn['DEVICE_SERIAL_NUMBER']
json_log = device.get_log_file()
