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

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 6.5.0 or above.

Understanding the difference between high availability On-Premise Pollers and On-Premise Poller Groups

The On-Premise Poller Group represents an evolution of high availability configurations by introducing a flexible system for managing and monitoring tasks. Knowing the difference between high availability On-Premise Pollers and On-Premise Pollers is key to ensuring robust service continuity and reliability in your monitoring setup.

Benefits of On-Premise Poller Groups

Scalability: On-Premise Poller Group can easily scale to include more On-Premise Pollers as demand increases, without major reconfiguration of the system.

Improved resource utilization: By monitoring and optimally distributing workloads, On-Premise Poller Groups ensure that resources are used efficiently and can support more extensive monitoring operations.

Increased reliability: With built-in failover capabilities and dynamic load balancing, the system is more robust and resilient to failures, providing better overall service availability.

Streamlined operations for MSPs: MSP admins can manage multiple customers' monitoring needs from a centralized interface, assign resources on the fly, and adjust configurations to quickly adapt to changes in customer requirements.

Adding an On-Premise Poller Group

1. Log in to your OpManager Nexus 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.
