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:
- 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
