= Events and Alarms =


Many services within NetXMS gather information and generate events that are forwarded to NetXMS Event Queue. Events can also be emitted from agents on managed nodes, or from management applications residing on the management station or on specific network nodes. All events are processed by NetXMS Event Processor one-by-one, according to the processing rules defined in Event Processing Policy. As a result of event processing, some actions can be taken, and event can be shown up as alarm. NetXMS provides one centralized location, the Alarm Browser, where the alarms are visible to your team. You can control which events should be considered important enough to show up as alarms. You and your team can easily monitor the posted alarms and take appropriate actions to preserve the health of your network.
