Interpreting Discovery Table Data

The Recent Activity, License Management, Problems, and Recently Unreachable tables organize information in the following columns:

E (Exists)	The listed IP address exists in the network. All devices will receive this status to indicate where NetMRI first discovered the address.
P (Port Scanned)	If NetMRI is configured to use fingerprinting, device fingerprint status is listed in this column.
R (Reached)	Shows whether NetMRI has sent a packet to the device and received a reply, establishing that the device is reachable. Devices are typically tested for reachability through SNMP and the CLI, usually with an ICMP Ping operation.
S (SNMP Credentials)	Indicates the status of the SNMP credential guessing process.
SC (SNMP Collection)	Shows the status of SNMP data collection for the device. Success indicates that a device successfully allows data collection through SNMP. If this is not successful, check the S field to see whether the correct credential is given.
C (CLI Credentials)	Displays the status of the CLI credential guessing process.
CC (Config Collection)	Indicates whether a device supports command-line connectivity and whether the configuration collection is successful. If this is not successful, check the C field to see whether the correct credential is given.
G (Groups)	Shows the status of the device group generation process. Success indicates that a device has been assigned to at least one group.
DB (Discovery Blackout)	Indicates whether or not the selected device is in a Discovery Blackout period. Two states are possible, In Blackout and Not in Blackout.
CB (Change Blackout)	Indicates whether or not the selected device is in a Change Blackout period. Two states are possible, In Blackout and Not in Blackout.
License Status	Licensed devices are listed as such. Unlicensed devices are non-network devices or devices for which NetMRI license limits have been exceeded. Unmanaged devices are those which NetMRI will discover, but not manage.
Type	Lists the device type as determined by NetMRI.
Last Timestamp	Date and time the data in the device records were updated or verified as unchanged.
Last Action	The last action performed by NetMRI on the device after discovery takes place. For example, Device Groups: Successfully assigned to device groups indicates that the device was successfully discovered and added to a device group.
Last Seen	The date and time when the device was last seen on the network. For example, reading the IP address in the ARP table from a router.
First Seen	Date and time when the listed device was first detected by the NetMRI appliance.

To display an explanatory tooltip, hover over the E, P, R, S, SC, C, CC, and G column headings.

The following status icons appear in the tables:

Icon	Name	Description
	OK	The device passed the process.
	Error	The device failed the process.
	Not Applicable	The process is not applicable to the device.
	Skipped	The device skipped the process.
	Running	The process is in progress.

A pink row in the table indicates that there is at least one failed process for the device.

To see the action that generated a status, along with the timestamp and source of the action, hover over a status icon.

Each of the column categories provides a reason or an explanation of how a discovery phenomenon took place upon each device. Consider the E (Exists) column, for example. Possible explanations for why a device was found to exist in the network include the following:

Exists: Device exists / Source: SNMP Exists: Device exists / Source: NIOS

Exists: Device exists / Source: Net-SNMP Exists: Device exists / Source: NetMRI

Exists: Device exists / Source: CIDR Table Exists: Device exists / Source: Seed

Exists: Device exists / Source: CDP Exists: Device exists / Source: Wireless Controller

Exists: Device exists / Source: Route Table Exists: Device exists / Source: IP Phone

Exists: Device exists / Source: ARP Table Exists: Device exists / Source: Call Server

Exists: Device exists / Source: Path Exists: Device exists / Source: VPN Table

Exists: Device exists / Source: CDP Table Exists: Device exists / Source: Wireless AP

Exists: Device exists / Source: LLDP Exists: Device exists / Source: Subnet Scan

Exists: Device exists / Source: HSRP Exists: Device exists / Source: Discover Now

Exists: Device exists / Source: VRRP
