# Verification & Troubleshooting

### Verify Collector Status <a href="#verify-collector-status" id="verify-collector-status"></a>

With the Collector correctly installed and configured it should register itself with SIFF:

1. Within the Admin app, browse to the *Collectors* page
2. If the collector is able to communicate with SIFF you will see a new entry and the status should show up as `online`

### Troubleshooting <a href="#troubleshooting" id="troubleshooting"></a>

#### Collector does not register with SIFF <a href="#collector-does-not-register-with-siff" id="collector-does-not-register-with-siff"></a>

This can happen if the Collector service fails to start due to a missing collector.yml, or a problem binding to the default listening ports (see the [System Requirements](https://docs.siff.io/install/system-requirements)). This can also happen even if the collector is running but cannot communicate with the SIFF platform.

For more details take a look at collector.log in the Collector installation directory.

#### Collector status showing offline <a href="#collector-status-showing-offline" id="collector-status-showing-offline"></a>

If the Collector is showing as offline then either the service is not running or there is a problem communicating with SIFF.

* Check the Collector service is running
* Take a look at the collector.log in the Collector installation directory for more details.
