You can make bulk changes to nodes in NPM using theManage Nodesfeature. This allows you to select multiple nodes and edit their properties, such as the polling method, the polling frequency, the SNMP credentials, the custom properties, and more.You can also use theEdit Nodesfeature to assign or unassign pollers to nodes, such as the Universal Device Poller (UnDP), the Hardware Health Poller, the Wireless Poller, and more12.Reference:1: Change the polling method for a node3,2: Manage pollers using Device Studio4

When a router monitored by NPM reboots, the interface indexes may change, causing the interface statuses to become unknown in NPM. This is because NPM uses the interface indexes to identify and poll the interfaces. To resolve this issue, you need to remove the unknown interfaces from NPM and then run a list of resources on that node to discover the interfaces with the new index IDs. You can then add the interfaces back to NPM and resume monitoring them.Reference:

An alert limitation is a filter that restricts the scope of an alert to a specific set of objects, such as nodes, interfaces, applications, or groups. You can use an alert limitation to create an alert that only applies to a select set of nodes in your network, and exclude the rest.To set an alert limitation for the nodes to be included in the alert, follow these steps1:

ClickAlerts & Activity > Alerts > Manage Alerts.

Find the alert that you want to edit or create a new alert.

On theTrigger Conditiontab, define the condition that triggers the alert, such asPercent Loss is greater than or equal to 50.

On theScope of Alerttab, selectLimit the scope of this alert to a specific subset of objects.

Choose the method to define the subset of objects, such asSelect objects manually,Use a custom SWQL query, orUse a custom SQL query.

Select or enter the criteria to filter the objects, such as the node name, IP address, group, custom property, or any other attribute.

ClickAdd Selected Objectsto add the objects to the alert limitation.

ClickNextand complete the rest of the alert configuration.

You can now save and enable the alert, and it will only notify you when packet loss meets or exceeds 50% for the nodes that you have selected in the alert limitation.Reference:1: Limit the objects an alert applies to

If you want to see a statistic that NPM does not support out of the box, you can use the Manage Pollers feature in Device Studio or the Universal Device Pollers (UnDP) feature to collect the statistics you want from the device. Both features allow you to create custom monitors for almost any statistic provided by SNMP based on its Management Information Base (MIB) and object identifier (OID). You can also assign the custom pollers to specific devices, view the polled data in the Orion Web Console, and use the data in alerts and reports. The difference between the two features is that Manage Pollers is a web-based interface that simplifies the creation and management of custom pollers, while UnDP is a standalone application that offers more advanced options and flexibility. Device templates and application monitor templates are not features that can be used to collect custom statistics from devices, as they are predefined sets of monitors for specific device types or applications that NPM supports out of the box.Reference:

Capacity planning is available for the following metrics of monitored nodes, interfaces, and volumes: CPU utilization on nodes, memory usage on nodes, space usage on volumes, receive (in) utilization on interfaces, and transmit (out) utilization on interfaces1. Capacity planning allows you to monitor capacity usage trends on the network and forecast capacity issues based on historical data and customizable thresholds.You can view capacity forecasting graphs and tables on the details views of nodes, interfaces, and volumes, or use the Top XX Capacity Problems widget to see a list of objects whose usage trend is rising2.Reference:Monitor capacity usage trends on the network and forecast capacity issues in NPM,Forecast capacity for nodes, interfaces, or volumes in NPM
