The Discovery Ignore List is a feature that allows you to specify the IP addresses or hostnames of the devices that you do not want to monitor or discover in the future. You can add devices to the ignore list manually or automatically during the discovery process. Once a device is added to the ignore list, it will be skipped by any subsequent discovery. You can also remove devices from the ignore list if you change your mind and want to monitor them later. References: Add devices to the Discovery Ignore List in NPM, Remove devices from the Discovery Ignore List in NPM, How to View Devices on Your Windows Network and What to Do If You Can’t See Them

 Device Studio Poller is a feature that allows users to create custom pollers for devices or technologies that are not supported by default in NPM. It can poll multiple OIDs for a given technology, perform logical operations or transformations on the polled data, and display the polled values in existing resources. However, it does not collect data from Orion Failover Engine or Hot Standby Engines, which are features of Orion High Availability that ensure continuous monitoring in case of primary server failure12. References: 1: Create pollers in Device Studio for NPM3, 2: When Good OIDs Go Bad: Customizing Device Pollers, 3: Manage Pollers (AKA Device Studio) question

 Map status thresholds determine how the status of a map is calculated based on the status of its child objects. If you set the map status threshold to above 50%, it means that the map will be up if more than half of its child objects are up, regardless of the severity of the down objects. This can cause a situation where half of your objects in a nested map are down, but the top level map is up, because the top level map only considers the status of the nested maps, not the individual objects within them. To avoid this, you can lower the map status threshold to a value that reflects the desired level of availability for your network, or use custom map status thresholds to specify different values for different maps. References: Set map status thresholds in NPM, Create nested maps in NPM, How to map through a deeply nested array of objects?

 NetPath is a feature of NPM that helps you identify network problems faster by automatically creating a map of the problem area, with a wide variety of supporting information. NetPath displays the performance details of devices inside and outside of your network. NetPath can analyze paths to any network segment, whether it is on-premise, cloud, or hybrid. NetPath uses distributed monitoring and path analysis to discover how applications are delivered through the network to your users. You can deploy agents on Windows computers that act as synthetic users and use advanced probing to discover and test the network path that traffic takes to any network endpoint, such as your local file print server, your website, or external websites. NetPath can also incorporate data from NPM, NCM, and NTA about your on-premises gear, as well as data from the Internet nodes and providers12. References: 1: Discover your network paths in NPM3, 2: NetPath - Easy Visual Network Path Analysis | SolarWinds4

NPM can monitor a wide range of network devices and infrastructure, including routers, switches, firewalls, servers, and virtual machines. However, some devices may not support standard protocols such as SNMP or WMI, or may have specific metrics that are not monitored out-of-the box by NPM. In such cases, you can extend NPM’s monitoring to non-standard devices by using object identifiers (OIDs) organized in management information bases (MIBs). OIDs are numeric strings that uniquely identify a variable in a MIB. MIBs are hierarchical databases that define the properties and values of the variables that can be monitored on a device. By importing device-specific MIBs into the SolarWinds MIB Database, and creating custom pollers based on OIDs from the MIBs, you can monitor any metric that is available on the device. You can also display the polled data in the web console using dedicated or existing resources12. References:

 The best way to monitor an SNMP metric that NPM is not monitoring out-of-the-box is to create a custom poller using the Universal Device Poller (UnDP) tool. A custom poller allows you to monitor specific aspects of your network devices using SNMP, by selecting the OIDs that correspond to the metrics you want to collect. You can then assign the custom poller to the devices you want to monitor, and view the results in the Orion Web Console, as charts, tables, or gauges. You can also use custom pollers to create alerts and reports based on the collected data. References: Monitor custom statistics based on OIDs with Universal Device Pollers in NPM, Create a custom poller, Assign Universal Device Pollers to devices monitored in NPM

NPM polls static properties, such as interface speed and duplex mode, from the firewall devices using SNMP. NPM also collects traffic statistics, such as bytes in and bytes out, from the firewall interfaces using SNMP or NetFlow. NPM then calculates bandwidth consumption based on the total amount of bytes coming through the firewall over a given time interval. Bandwidth consumption is expressed as a percentage of the interface speed. For example, if a firewall interface has a speed of 100 Mbps and NPM polls 10 MB of bytes in and 10 MB of bytes out in one minute, the bandwidth consumption is 20% [(10 MB + 10 MB) / 100 Mbps * 100%]1. References: Monitor firewalls with NPM, Calculate bandwidth utilization on an interface

NPM can monitor the network bandwidth utilization of your devices, interfaces, and applications using SNMP and NetFlow protocols. Network bandwidth utilization is the amount of data transmitted or received over a network link in a given time period. High network bandwidth utilization can indicate network congestion, packet loss, latency, or other performance issues that can affect the email delivery speed. By looking at the network bandwidth utilization of thedevices and interfaces involved in the email communication, you can identify the possible bottlenecks or sources of network problems that might be causing the email slowness. References: Monitor network bandwidth utilization in NPM, Network Bandwidth Analyzer Pack, How to Monitor Network Bandwidth Using the Command Line.

One possible reason for not being able to show the polled results as charts on the Orion Web Console is that you did not set the poller to collect historical statistics. Historical statistics are required for displaying charts and gauges in the web console, as they provide the data points for plotting the trends and values over time. If you only set the poller to collect current statistics, you will only be able to view the polled results as tables or lists in the web console. To set the poller to collect historical statistics, you need to edit the poller and select the Keep Historical Data option in the Poller Properties page. You can also specify the retention settings for the historical data, such as the frequency and duration of data collection and storage1. References: Create a custom poller
