Update the Cloud Link Service Automatically

You can now easily keep all your Cloud Link Service up-to-date with the latest version. You can set up automatic updates or scheduled updates to save time and avoid manual tracking of the Cloud Link Service.

You can set up update options on the Configuration tab:

  • Automatic update: Select to allow auto-update of sensors as and when a new version is available.
  • Custom update: Select to schedule auto-update of the sensor for a specific day and time.

Prerequisites

  • The NetWitness Platform (host) is on version 11.6.1 or later.
  • Ensure that the Cloud Link Service is in a connected state in the UI to start the update.

Note

  • The Sensor Update button will be enabled only when there is a new version available.
  • During the update process, the Cloud Link Service will get disconnected and data transfer to the cloud will be paused. If the update fails, the Cloud Link Service will revert to the last installed version.
  • Cloud Link Service will begin updating automatically within 10 minutes if the automatic update option is enabled.

Important

  • From version 12.4 or later, NetWitness no longer supports CentOS 7 and only supports Alma OS. As a result, upgrading only the Cloud Link Sensor from a lower version (12.3.1 or older) to 12.4 is not possible. To resolve this issue, we recommend upgrading all NetWitness Platform services to version 12.4. This step ensures a successful upgrade for the sensors. For more information on upgrade, see NetWitness Upgrade Guide 12.4.
  • For users onboarded on version 12.4, you must follow the installation procedure to deploy the sensor to the decoder. For more information, see Install Cloud Link Service.

To update the Cloud Link Service automatically

Limitations for sensor update

Limitations associated with this version of the sensor are included below:

  1. When a new version of the sensor update is available, for example, 11.6.1, the Sensor Update button is enabled and ready to update the sensor. When you click Sensor Update, the sensor update starts. However, at the same time if a new rpm for the sensor update is uploaded, for example, 11.7, there are high chances the sensor update will not be overridden, causing the sensor to not be updated with the latest version.

  2. When a new version of sensor update is available, and you have configured for manual updates, the sensor update will not be triggered automatically. In this scenario, you need to update to the new version manually. However, if a new version of the sensor update is released after changing the setting to automatic, all sensor updates will be performed automatically from that moment.
