On-Premise Poller Group

The On-Premise Poller Group is a collection of On-Premise Pollers designed to distribute monitoring workloads efficiently. It simplifies the allocation of monitors across selected On-Premise Pollers and can include both primary and standby On-Premise Pollers.

How it helps

Balanced workloads: The On-Premise Poller Group evenly distributes workloads among On-Premise Pollers and monitors their CPU and memory usage to prevent any On-Premise Poller from being overwhelmed. 

Continuous monitoring: If a primary On-Premise Poller becomes unavailable, a standby On-Premise Poller is automatically promoted to take over, ensuring uninterrupted monitoring.

Efficient MSP operations: It allows MSP admins to efficiently manage On-Premise Pollers by creating On-Premise Poller Groups and assigning them to specific customers, ensuring consistent monitoring of their resources.

Prerequisites for adding an On-Premise Poller to an On-Premise Poller Group

Note

To migrate an existing On-Premise Poller to an On-Premise Poller Group, follow the steps outlined in the Migrate to the On-Premise Poller Group document.

To add a new On-Premise Poller to an On-Premise Poller Group, ensure the following prerequisites are met.

  • The On-Premise Poller should not have any monitors associated with it.
  • The On-Premise Poller should not be included in any user-defined location profile.
  • The On-Premise Poller should not be in a down state.
  • The On-Premise Poller should not be part of another On-Premise Poller Group.
  • If the On-Premise Poller is a primary On-Premise Poller with high availability, neither the primary nor the high availability On-Premise Poller can be added to the On-Premise Poller Group.
  • Super admins, admins, MSP admins, and MSP customers can add an On-Premise Poller Group.
  • Ensure that all On-Premise Pollers in an On-Premise Poller Group are on the same network.
  • The On-Premise Poller version should be 6.0.0 or above.
Note

If you want to upgrade or auto-upgrade On-Premise Pollers to the latest version, follow the steps in this document.

Adding an On-Premise Poller Group

  1. Log in to your Site24x7 account.
  2. Add an On-Premise Poller, if you haven't added one yet.
  3. Once the On-Premise Poller is installed, click Admin > On-Premise Poller Group.
  4. Click the plus + symbol beside On-Premise Poller Group.
  5. Specify the following information to add the On-Premise Poller to an On-Premise Poller Group:
    1. On-Premise Poller Group Name: Specify a name to identify the On-Premise Poller Group.
    2. Select Primary On-Premise Pollers: Search or choose the On-Premise Poller which you wish to add to the group as a primary On-Premise Poller.
    3. Select Standby On-Premise Pollers: Search or choose the On-Premise Poller which you wish to add to the group as a standby On-Premise Poller. Including a standby On-Premise Poller is recommended.
      Note: When a primary On-Premise Poller goes down, its monitoring resources will be taken over by the standby On-Premise Poller, which will then become the new primary On-Premise Poller. The original primary On-Premise Poller will switch to standby mode, even while in a down state.
  6. Configuration Profiles
    1. Customer Name: This drop-down, which lists the associated MSP customer, will be visible only to the MSP admin. When choosing this option, the On-Premise Poller Group will be propagated to selected customers.
    2. Threshold and availability: You can edit the Threshold Profile of your On-Premise Poller Group monitor either through the Configuration Profile or by following the steps below:
      1. Navigate to On-Premise Poller > On-Premise Poller Group.
      2. Select the On-Premise Poller Group you want to edit.
      3. Edit the parameters that needs to be changed.
      4. Click Save.
      Note

      If an On-Premise Poller is added to the On-Premise Poller Group, the down alert for the individual On-Premise Poller will be suppressed. Instead, the alert will be sent from the On-Premise Poller Group.

  7. Alert Settings:
    1. Notification Profile: Notification profiles help to configure when and who gets notified in case of downtime. Choose a notification profile from the drop-down list, use the default profile available, or create a custom notification profile.
    2. User Alert Group: Select the user group that needs to be alerted during an outage, or add multiple users to a group.
  8. Click Save.

Location Profile: If you add an On-Premise Poller to the group, only the On-Premise Poller Group will be listed, and the individual On-Premise Poller associated with it will not be visible in the Location Profile list.

MSP admins can allow their customers to choose the On-Premise Poller Group as their monitoring location by following these steps:

  1. Select the customer name from the drop-down menu in the configuration profile. When this option is selected, the On-Premise Poller Group will be propagated to the selected customers.
  2. When adding a monitor, the customer can choose the On-Premise Poller Group as their monitoring location. The screenshot below shows the Monitoring Locations drop-down listing the On-Premise Poller Group for the MSP customer.

Editing an On-Premise Poller Group

You can edit an On-Premise Poller Group to update its display name and make configuration changes. For this:

  1. Go to Admin > On-Premise Poller > On-Premise Poller Group.
  2. From the list of On-Premise Poller Groups, click the hamburger icon Hamburger icon next to the desired On-Premise Poller Group and click Edit.
  3. On the Edit On-Premise Poller page, you can edit the On-Premise Poller Group Name and User Alert Group details.

Adding a new On-Premise Poller to an On-Premise Poller Group

To add a new On-Premise Poller to the On-Premise Poller Group, follow the steps below:

  1. Go to Admin > On-Premise Poller > On-Premise Poller Group.
  2. From the list of On-Premise Poller Groups, choose the On-Premise Poller Group that you want to edit.
  3. Click the hamburger icon Hamburger icon next to the desired On-Premise Poller Group and click Add On-Premise Pollers.
  4. In the window that opens, choose the On-Premise Poller that you want to add and click Update.

Removing On-Premise Pollers from an On-Premise Poller Group

To remove an On-Premise Poller from an On-Premise Poller Group, follow the steps below:

  1. Go to Admin > On-Premise Poller > On-Premise Poller Group.
  2. From the list of On-Premise Poller Groups, choose the On-Premise Poller Group that you want to edit.
  3. Click the hamburger icon Hamburger icon next to the desired On-Premise Poller Group and click Remove On-Premise Pollers.
  4. On the On-Premise Poller Group Settings page, you can update the following settings:
    1. On-Premise Poller to delete from the On-Premise Poller Group: Select the On-Premise Poller that you want to delete from the On-Premise Poller Group from the drop-down menu.
    2. On-Premise Poller to take over the associated monitors: If the On-Premise Poller you are deleting has an attached monitor, you can either select another On-Premise Poller from the drop-down list to take over the monitors or choose Redistribute among On-Premise Pollers to distribute the load among existing primary On-Premise Pollers. If there are no attached monitors to the On-Premise Poller you are deleting, you can delete it directly.
  5. Click Update.

Redistributing monitors within an On-Premise Poller Group

Use the Redistribute Associated Monitors option to redistribute monitoring tasks within the On-Premise Poller Group, balancing workloads and enhancing efficiency.

To do this:

  1. Go to Admin > On-Premise Poller > On-Premise Poller Group.
  2. From the list of On-Premise Poller Groups, choose the On-Premise Poller Group that you want to edit.
  3. Click the hamburger icon Hamburger icon next to the desired On-Premise Poller Group and click Redistribute Associated Monitors.

You can use this option in the following scenarios:

  • When adding a new On-Premise Poller, use this option to balance the monitoring load among the On-Premise Pollers in the group.
  • When a primary On-Premise Poller is down and no standby is configured, use this option to redistribute the workload of the monitors previously handled by the downed On-Premise Poller.
  • When deleting an On-Premise Poller, use this option as described in this step to redistribute the workload of the monitors previously handled by the On-Premise Poller being removed.
Note

You can use the Redistribute Associated Monitors option only once every five minutes.
