Re-install an agent

You can reinstall an agent on a device if it stops communicating with N-central. The agent may stop communicating for several reasons, such as technical issues or accidental removal. Instead of uninstalling and reinstalling the agent manually, you can reinstall it directly from N-central. This option is available on all operating systems.

When you reinstall the agent from N-central, the system preserves all tasks, monitoring services, and historical data.

To reinstall an agent, a probe must be assigned to the device. The probe must also have Discovery permission enabled for that site. If no probe with Discovery access is available, the Reinstall Agent option is not available.

  • To assign a probe to the device, select the device, then select Assign Probe.
  • To edit probe permissions, go to Administration > Probes, select the probe name, and turn on the required permissions under the Grant Access tab.

To reinstall the agent:

  1. Go to Views > All Devices.
  2. Select the device name.
  3. Select Settings > Local Agent.
  4. Select Reinstall Agent.

You can also reinstall the agent from the Device Details page.

  1. Go to Views > All Devices.
  2. Select the device name.
  3. Select Add Task > Reinstall Agent.

N-central downloads the agent executable to the device and starts the installation. After the installation finishes, the agent connects with N-central.

Reinstalling the agent on multiple devices

Time Impact

The more devices you reinstall the agent on, the longer the process takes.

To re-install the agent on multiple devices:

  1. Go to Views > All Devices.

  2. Select the check box for each device.

  3. Select Add Task > Maintenance > Reinstall Agent.
