 SNMP traps are unsolicited messages sent by network devices to report events or issues. If NPM receives too many traps from devices that are not managed by NPM, or traps that are not relevant for monitoring, the performance of the Orion Web Console can be affected. To resolve this issue, you can point the devices to a trap manager, such as Kiwi Syslog Server, and configure it to filter out unwanted traps before forwarding the remaining ones to the Orion Platform. This way, NPM will only process the traps that are important for monitoring and alerting, and reduce the load on the database and web server. References: Configure SNMP traps in NPM, Filter traps in Kiwi Syslog Server, [Forward traps to another host in Kiwi Syslog Server]

 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.

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
