Collector Configuration & Rescanning

Once enabled, Asset Manager collectors cycle through network scans at the frequency you specify, so it's important to be aware of the impact of your rescan interval on the network. Your goal in setting a rescan interval that permits discovery to occur smoothly without over-scanning or under-scanning.

Each Asset Manager zone generally contains multiple unique collectors (for example, unique in that they are not shared, copied, or otherwise transferred across zones). Each collector has its own rescan interval and target list.  

• When configuring Path discovery or Host discovery to scan a large target list or a large set of discovered routes, use a longer rescan interval to achieve a smooth rescan cycle.  
• To check the status of already discovered IPs or SNMP-discovered IPs, another collector can be configured with a short rescan interval and no target list. Regardless of rescan interval, it is immediately scanned whenever a new device is discovered. This behavior is not affected by the rescan interval setting.

Each discovery type has a default configuration associated with it.  These become active when you enable the discovery type.
