The following table describes the discoveryOverview view.

Table 1. discoveryOverview view
Column name Description Containing table
className

Class of devices to which this device belongs.

entityClass
currentTime The current time is given as a visual reference aid only. NA
entityId

Foreign key to the entityNameCache table. Must be unique for each entity across all domains.

entityData
entityName

IP address, DNS name, or sysName for this device. For example, an IP address such as 172.20.1.7, or a DNS name, such as company-abc.net.

entityData

A flag to show whether the device has had interface filtering applied to it or not. If you do not see all the information for the device that you expect, the information might have been filtered out. You can do an SNMP walk of the device using the MIB Browser with the option to ignore filtering.

discoveryAttributes
ipAddress

IP address through which this entity was discovered and through which it is monitored.

physicalChassis
firstDiscoveryComplete

Date and time when the entity was first uploaded to the NCIM topology database.

entityData
lastDiscovered

Date and time when the Details agent last accessed the device.

physicalChassis
lastModified

Date and time when the last detected change on the device was reflected in the NCIM topology database. For example, if an interface name on the device changes, this is the time at which that change was uploaded to NCIM.

entityData
rebootTime

Date and time when the device was last rebooted. This is calculated based on the sysUpTime MIB value retrieved from the device, so Last Reboot is only available if the sysUpTime was retrieved. For example, for devices with no SNMP access, the value of Last Reboot is NULL.

Calculated based on data in the chassis table
