5. Data Streams Search Target (optional) - The target path search to fetch from.

Advanced Settings

1. Hour range filter (required, default: 10) - Inspect all logs within the last specified hours and extract devices from all data received. Minimum value is 1; Maximum value is 72.
2. Page size (required, default 500, max 500) - Enter a page size to control the number of items to return per request to the Search API. Decreasing this number may improve fetch stability.
3. Fetch devices without hostname - Select whether to fetch devices from Elasticsearch that do not have a hostname.
4. Parse dynamic fields - Select this option to parse all the fields fetched from the API as dynamic fields. These are fields created during the fetch process. They can be queried, and their names and types are defined by the field name and value parsed.
5. Use fetch time for Last Seen - Select this option to set that all entities (devices and users) fetched by this adapter have their Last Seen set to the time the entity was fetched (fetch_time).

Axonius uses the Elasticsearch 7.10 API.
