Export all Hosts as CSV
The Syncer has a hidden endpoint that returns every host in the database as a
single CSV file. The endpoint is not linked from the menu — you reach it by
appending /csv to the Host admin URL:
https://<your-syncer>/admin/host/csv
The response is a download named hosts_export_<YYYYMMDD_HHMMSS>.csv.
Permissions
The endpoint is gated by the normal admin login and requires the host right
on the current user. Unauthenticated requests get a 401 Unauthorized.
What is Exported
- All hosts where
is_objectis notTrue(templates are excluded) - Sorted alphabetically by hostname
- One row per host, one column per field
Fixed Columns
| Column | Description |
|---|---|
hostname |
Host name as stored in the Syncer. |
object_type |
Object type of the host. |
available |
True/False — whether the host is currently marked as available. |
source_account_name |
Name of the account the host was last imported from. |
folder |
Resolved target folder (e.g. for Checkmk). |
last_import_seen |
Timestamp the host was last seen by an import run (YYYY-MM-DD HH:MM:SS). |

inventory_<name> |
One column per inventory field listed in export_inventory_list. |
Configurable Columns
Which labels and inventory fields end up in the CSV is controlled in the global Syncer configuration, not via a query parameter:
export_labels_list— list of label keys; each one becomes a column prefixed withlabel_.export_inventory_list— list of inventory keys; each one becomes a column prefixed withinventory_.
Both settings live in the Syncer Config (Local Config Variables). Hosts that don't have a value for a configured label or inventory key get an empty cell.
