 Bandwidth usage is the amount of data transferred over a network connection in a given time period. It is an indicator of how much traffic is flowing through a network device or link. Peak network traffic is the highest level of bandwidth usage that occurs during a specific time interval, such as an hour, a day, or a week. Monitoring peak network traffic can help you identify potential bottlenecks, plan for capacity, and optimize network performance. NPM can monitor bandwidth usage on nodes and interfaces using SNMP, WMI, or NetFlow protocols. You can view bandwidth usage charts and reports in the web console, as well as set alerts and thresholds for bandwidth utilization. References: Monitor bandwidth usage in NPM; SCP Study Aid - NPM, page 11.

 Packet loss is a measure of how many packets are lost or discarded during transmission over a network. Packet loss can cause network performance issues such as slow response time, jitter, and degraded voice quality. NPM can monitor packet loss on nodes and interfaces using ICMP ping or SNMP statistics. You can review the packet loss metrics on the Node Details or Interface Details views, or create a custom chart or report to compare packet loss across multiple nodes or interfaces. By reviewing the packet loss on the nodes on either side of the connection, you can identify which node or interface is experiencing the problem and troubleshoot the root cause. You can also use the Performance Analysis dashboard (PerfStack) to correlate packet loss with other metrics such as response time, CPU load, memory usage, buffer misses, and interface errors123. References:

To identify the custom poller within the trigger condition, you need to use the Unique Name of your UnDP. The Unique Name is a user-defined identifier that you assign to your custom poller when you create it using the Universal Device Poller tool. The Unique Name is also used to reference the custom poller in the Orion database and the web console. When you select “I want to alert on: Custom Poller” in the alert configuration, you can choose the specific custom poller by its Unique Name from the list of available pollers. You can also use the Unique Name to filter, group, or sort the custom poller data in reports, charts, or tables. References: Create a custom poller, Create an alert for a custom poller, View custom poller data
