# Managing Probes

## Checking a probe

**Probe Info**, at the top of **Networking** › **Devices**, shows every probe with:

- a green dot (**Online**) if its last scan arrived within the scan interval, a grey dot (**Not recent**) otherwise;
- the name, operating system and IP address of the machine;
- **Last Sync**, the time of the last scan received;
- **Agent Version**, the version of the probe, with a download icon when a newer version is available.

If a probe is not recent, see [Troubleshooting](https://wiki.cyberguard.srl/dim/networking/network-devices/troubleshooting.md#the-probe-is-not-recent).

## Changing the configuration

Networks, credentials and scan interval are changed only in the portal (see [Configuring the Probe](https://wiki.cyberguard.srl/dim/networking/network-devices/configuring-targets.md)). The probe receives the changes by itself at its next cycle; you never need to reinstall it.

## Starting and stopping the service

From PowerShell opened with **Run as administrator**:

```powershell
Get-Service CGDIMNetworkProbe      # status
Restart-Service CGDIMNetworkProbe  # restart, for example to apply a configuration change right away
Stop-Service CGDIMNetworkProbe     # stop
Start-Service CGDIMNetworkProbe    # start
```

You can also use the **Services** console: the service is **CyberGuard Device Inventory Manager - Network Probe**.

## Updating the probe

The probe does not update itself. When a download icon appears next to its version in **Probe Info**:

1. Click **Download Agent** and extract the new package on the machine.
2. In the configuration of the probe, click **Generate installation code**.
3. From an administrator prompt in the extracted folder, run the command shown in the portal:

```powershell
.\CyberGuard-NetworkProbe.exe --install <installation code>
```

The command updates the probe in place: same folder, same service, same configuration. The new code replaces the previous registration only if the registration succeeds.

## Moving the probe to another machine

The probe's registration is tied to the machine where it was installed: copying its folder to another machine does not work.

1. Install the probe on the new machine with a new installation code (see [Installation](https://wiki.cyberguard.srl/dim/networking/network-devices/installation.md)). The new registration replaces the old one.
2. Uninstall the probe from the old machine (see below).

## Uninstalling the probe

From an administrator prompt, run the installed executable:

```powershell
C:\CyberGuard\DIM-NetworkProbe\CyberGuard-NetworkProbe.exe --uninstall
```

The command must be run from `C:\CyberGuard\DIM-NetworkProbe`, not from the copy you downloaded. It removes the Windows service but leaves the folder: to remove the probe completely, delete `C:\CyberGuard\DIM-NetworkProbe` afterwards.

## Deleting a probe from the portal

When a site no longer needs a probe:

1. Uninstall the probe from its machine.
2. In the **Probe Configuration** page, delete its targets and its SNMP credentials.
3. In the **Probes** page, click the delete icon of the probe and confirm.

A probe that still has targets or credentials cannot be deleted. The network devices it found stay in the list: they become **Disconnected** after 7 days without answers, and you can delete them from their page. They keep their notes and asset data: if another probe later finds the same IP address, it takes them over.
