SolarWinds SCP-NPM Exam With Confidence Using Practice Dumps

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

The Universal Device Poller (UnDP) is a feature of SolarWinds NPM that allows you to create custom monitors for almost any statistic provided by SNMP based on its Management Information Base (MIB) and object identifier (OID). An OID is a unique identifier for a variable that can be polled or set via SNMP. The UnDP retrieves management data in the OID format from the devices that support SNMP. The other formats (WMI, XML, ANSI 1) are not used by the UnDP. References:

 By default, Orion NPM retains Syslog messages in the database for seven days before discarding them. This means that any Syslog messages older than seven days are deleted from the database and cannot be viewed or searched in the web console. To change the default Syslog retention period, you need to modify the Database Settings on the Orion Polling Settings page in the web console. You can also use the Database Manager tool to manually delete or archive Syslog messages from the database. References: SolarWinds SCP Study Aid - NPM, page 19; NPM Administrator Guide, page 111.
