# Licensing

#### Requesting a License

You can request a [Basic License](https://www.elastiflow.com/basic-license) via the [ElastiFlow website](https://www.elastiflow.com/basic-license). This license will be good for one year, after which it can be renewed by requesting a new license. The Basic License only supports polling of Standard MIBS (IEEE and IETF).

You can also request a [30-day Premium Trial License](https://www.elastiflow.com/trial) via the [ElastiFlow website](https://www.elastiflow.com/trial). This license can only be renewed with approval of ElastiFlow. To request an extension, please send an email to <sales@elastiflow.com>.

The license key for ElastiFlow Premium Tier customers will be made available through our support system. A ticket will be opened, from which an authorized user can download the license key.

#### Adding a License

The following is an example of a license configuration, as defined in a docker-compose file:

```yaml
EF_LICENSE_ACCEPTED: 'true'
EF_ACCOUNT_ID: '606abcdefe3546eee123456a'

EF_LICENSE_KEY: 'eyJhbGciOiJIUzI1HghIEjTUI6IkpXVCJ9.eyJhdWQiOiJKNHHFYTFKNJKHgkjKjknhLjKJkhyiiutUYfyrdIutKjsYXN0aWZsb3ciLCJzdWIiOiI2MDNkODUwMDMzZDg2YjA3OTE5YjE5Y2EiLCJjb3IiOjEyOCwibHZsIjo5fQ.FQtYWSWutfjn9q6876GHgf5fghir45vsuDnxrDldbd7xR8'
```

and as defined in the systemd configuration:

```conf
export EF_LICENSE_ACCEPTED=true
export EF_ACCOUNT_ID=606abcdefe3546eee123456a

export EF_LICENSE_KEY=eyJhbGciOiJIUzI1HghIEjTUI6IkpXVCJ9.eyJhdWQiOiJKNHHFYTFKNJKHgkjKjknhLjKJkhyiiutUYfyrdIutKjsYXN0aWZsb3ciLCJzdWIiOiI2MDNkODUwMDMzZDg2YjA3OTE5YjE5Y2EiLCJjb3IiOjEyOCwibHZsIjo5fQ.FQtYWSWutfjn9q6876GHgf5fghir45vsuDnxrDldbd7xR8
```

### Licensing Configuration

#### EF\_LICENSE\_ACCEPTED

To use ElastiFlow NetObserv it is necessary to accept the terms of the License Agreement. By running this software, you and/or the organization using the software agree and are bound to the terms of an ElastiFlow Inc. End-User License Agreement (EULA). For the Community (no license key), Basic and Trial tiers, the applicable license is the ElastiFlow Community EULA, which may be found at: <https://www.elastiflow.com/community-license>. For Standard and Premium Commercial tiers the applicable license is the ElastiFlow Standard EULA, or other terms agreed in writing with ElastiFlow Inc. The ElastiFlow Standard EULA may be found at: <https://www.elastiflow.com/commercial-license>.

* Default
  * `false`

#### EF\_ACCOUNT\_ID

License keys are generated per account. This field must contain the Account ID for the License Key specified in `EF_LICENSE_KEY`.

#### EF\_LICENSE\_KEY

This field contains the License Key issued for this instance of collector. EF\_ACCOUNT\_ID must also contain the Account ID to which this key belongs.

#### EF\_LICENSE\_TELEMETRY\_HOSTS

NetObserv SNMP Trap is licensed by telemetry hosts, the number of devices sending SNMP traps to the collector. The maximum number of telemetry hosts will be set based on the provided license key. However, this maximum can be manually configured lower than the number specified in the license, for a given instance. This is usually done when it is desired to use multiple instances of the collector. For example, a subscription for 100 telemetry hosts can be split into 2 instances, of 50 telemetry hosts each, by setting `EF_LICENSE_TELEMETRY_HOSTS: 50` for each instance. If set to a value greater than allowed by the license key, the instances will be started with the telemetry hosts based on the license key.

* Default
  * `0` (uses the telemetry hosts based on the license)
