Overview

The Elastic Collector Profile is designed to enhance Gateway Clustering by allowing users to efficiently manage resources. To take advantage of this feature, select the Elastic option when downloading the NextGen Gateway (ISO, OVA, or Kubernetes) from the collector profiles page.

Configuration

Steps to configure and use the Gateway Clustering:

  1. Create the Gateway Collector Profile
  2. Download the Gateway Collector
  3. Install and Register the Gateway Collector

Step 1: Create Gateway Collector Profile

Once the feature flag is enabled, follow these steps to create a Collector Profile:

  1. Select a client from All Clients.
  2. Navigate to Setup > Account > Collector Profile.
  3. Click + ADD on the Collector Profile page.
  4. Fill in the details on the Add Gateway Collector Profile page:
    • Profile Name: Enter a name for the profile.
    • Profile Type: Select Elastic.
    • Description: Provide a brief description.
  5. Choose the Gateway Collector profile for download from the NextGen section:
    • Virtual Appliance (ISO): An ISO file is a disk image that contains the complete contents of an optical disc, such as a CD or DVD.
    • Virtual Appliance (OVA): An OVA (Open Virtual Appliance) file is a single-file distribution format that packages an OVF (Open Virtualization Format) along with its associated files, including virtual disk images.
    • Cloud-Native Application (INSTALLER): This format refers to installation packages specifically designed for cloud environments. Note: You can select a specific gateway version from the dropdown menu.
  6. Click Next to create the Gateway Profile.

Step 2: Download Gateway Collector

After creating the profile, click on the Download button to download the Gateway Collector.

Step 3: Install and Register the Gateway Collector

Follow the instructions in the links below to install and register the Gateway Collector for different environments:

By following these steps, you can successfully configure and utilize the Elastic Collector Profiles within OpsRamp, enhancing your resource management capabilities.

Steps to Perform the Elastic Operations

Scale Up

If you observe the tagged resources are overloaded on the gateway and want to reduce the load on it, you can perform the Scale Up operation. Before performing the Scale Up operation, make sure cluster should have sufficient resources like memory, CPU and disk for successful operation.

  1. Click on the three-dot menu next to the Collector Profile.
  2. Click Scale Up to trigger the operation.
  3. A Scale Up process will begin, creating a new replica.
  4. Click Refresh to see the updated status.

Now, a new replica has been created, and resources are automatically distributed between the Master Replica and the newly created replica.

Rebalance

The Rebalance operation is used when automatic rebalancing during Scale Up does not work as expected.

  1. Click on the three-dot menu next to the Collector Profile.
  2. Click Rebalance to trigger the operation.


Now the resources will be equally distributed between the Master Replica and the to newly created replica.

Scale Down

If you observe that multiple replicas are not required to monitor the resources, then you can perform the Scale Down operation to remove the replica from the cluster.

  1. Click on the three-dot menu next to the Collector Profile.
  2. Click Scale Down to trigger the operation.
  3. A Scale Down process will begin. The latest created replica will be removed from the cluster.
  4. Click Refresh to see the updated status.


Now the resources associated with this replica will be redistributed to the available replicas in the elastic profile.
