OK

Non-polling

Admin down

Uninitialized

Warning

Critical

Unknown

 

The following tables outline the states Entuity can assign to managed objects:

 

OK Object_state_OK_ENA.jpg

Tooltip Description
OK

Device or port is successfully responding to ICMP ping and SNMP polling.

An application is successfully responding to a TCP connect request.

For objects other than devices and ports (e.g. applications), extra information about the object state is not received.
ICMP responding (SNMP disabled) device-only status. A device managed as ping-only is responding correctly to ICMP ping.
SNMP responding (ICMP disabled) Entuity availability monitoring (applicationMonitor) excludes the port or device from ICMP ping. The port or device is responding to SNMP polling.

 

Non-polling Object_state_non-polling.jpg

 

Tooltip Description
ICMP and SNMP disabled

device-only status. The device has both ICMP ping and SNMP polling disabled:

  • it has been set as non-polling by editing its Poll Status attribute.
  • it is a ping-only device with a management IP address that is outside the range of IP addresses that Entuity availability monitoring (applicationMonitor) is configured to ping.
Unmanaged

port-only status. Entuity is not currently managing the port.

An option to remanage the port is available from the Context Menu.

 

 

Admin down Object_state_admin_down.jpg

 

Tooltip Description
Admin down

port-only status. SNMP polling of the port determines if it is set to admin down.

Entuity considers this an administrative choice, and therefore the port is not considered as operationally unavailable; port operational availability is set to 100%.
Admin down (ICMP disabled)

port-only status. Entuity availability monitoring (applicationMonitor) excludes the port or device from ICMP ping.

SNMP polling of the port determines if it is set to admin down. Entuity considers this an administrative choice, and therefore the port is not considered as operationally unavailable; port operational availability is set to 100%.

 

 

Uninitialized Object_state_uninitialized_ENA.jpg

Tooltip Description
Pending full object discovery this state is usually temporary. Discovery has started, but full discovery of all its attributes is not complete.
Status Not Available this state is usually temporary, e.g. a device may have this state after it is taken under management but before discovery of its attributes.
Unrecognized status this state is usually temporary, assigned when the object state does not meet the conditions for any other state category.

 

 

Warning Object_state_warning_ENA.jpg

Tooltip Description
ICMP not responding (not root cause) managed object is not responding to ICMP ping, but it is not the root cause. The managed object is responding to SNMP polling.
ICMP not responding

device or port is not responding to ICMP ping, although it did respond to the last SNMP poll. Entuity availability monitoring (applicationMonitor) has determined this object to be the root cause of the failure.

Entuity assigns this state to a port when the following set of conditions is met:

  • the device that this port is on is responding to ICMP ping and SNMP polling.
  • port does not respond to ICMP ping, e.g. because of a firewall configuration, and is therefore identified as the root cause.
Management IP not responding to ICMP device-only status. The device management IP address is not responding to ICMP ping, but other IP addresses are responding. The device also responds to SNMP polling.
Management IP not responding to ICMP (SNMP Disabled) device-only status. The device management IP address is not responding to ICMP ping but other IP addresses are responding. SNMP polling of the device is disabled.
Management IP not responding to ICMP, SNMP not responding device-only status. The device management IP address is not responding to ICMP ping, but other IP addresses are responding. The device is not responding to SNMP polling.
SNMP not responding device or port is not responding to SNMP polling, but it is responding to ICMP ping.
Degraded a managed object is in a degraded state, e.g. a Frame Relay DLCI.

 

 

Critical Object_state_critical_ENA.jpg

Tooltip Description
ICMP & SNMP not responding device or port is not responding to ICMP ping and SNMP polling. Entuity availability monitoring (applicationMonitor) has determined this object to be the root cause of the failure.
ICMP not responding, root cause (Port Down) port is not responding to ICMP ping, although it did respond to the last SNMP poll reporting the port as operationally down. Entuity availability monitoring (applicationMonitor) has determined this object to be the root cause of the failure.
ICMP not responding (SNMP disabled) device-only status. The ping-only device is not responding to ICMP ping, and Entuity availability monitoring (applicationMonitor) has determined this object to be the root cause of the failure.
Port down port-only status. Entuity availability monitoring (applicationMonitor) excludes the port or device from ICMP ping. SNMP polling of the port determines the port is operationally down.
Port down (ICMP disabled) port-only status. Entuity availability monitoring (applicationMonitor) excludes the port or device from ICMP ping. SNMP polling of the port determines the port is operationally down.
SNMP not responding (ICMP disabled) Entuity availability monitoring (applicationMonitor) excludes the port or device from ICMP ping. SNMP polling of the port determines the port is operationally down.
Down managed object is the root cause of the network failure.

 

 

Unknown Object_state_unknown_ENA.jpg

Tooltip Description
ICMP & SNMP not responding (not root cause) device or port is not responding to ICMP ping and SNMP polling. Entuity availability monitoring (applicationMonitor) has determined this object is not the root cause of the failure.
ICMP not responding (SNMP disabled) device-only status. A ping-only device is not responding correctly to ICMP ping. Entuity availability monitoring (applicationMonitor) identifies this device as not the root cause of the failure.
Parent down Entuity has set the application or port to the Unknown state, because its parent device is down.
Parent polling disabled Entuity has set the application or port to the Unknown state, because its parent device has polling disabled.
Parent unreachable Entuity has set the application or port to the Unknown state, because the parent device is unreachable to Entuity.
Unable to resolve hostname to IP device-only status. Entuity cannot resolve the device name to an IP address for a ping-only device. This could indicate an invalid device name or a problem with DNS.
Unable to resolve hostname to IP (ICMP disabled) device-only status. Entuity cannot resolve availability monitoring (applicationMonitor) excludes the port or device from ICMP ping. Entuity cannot resolve the device name to an IP address for a ping-only device. This could indicate an invalid device name or a problem with DNS.
Unknown

state is not known. This could be because it has not been polled yet or because of failures in the polling process.

Device status may be unknown when:

  • A device has been added recently, and Entuity (DSKernelStatic) has not yet completed creation and population of the associated streams. The amount of time this takes will depend on the size of the install, whether DSKernelStatic has recently restarted and how many objects have recently been modified or created.
  • Entuity availability monitoring (applicationMonitor) has failed.
  • Entuity availability monitoring cannot map a monitored IP address to a device. This can happen if a device has been added to the inventory twice. One will have the correct status, and the other will always be shown as Unknown (Entuity can only map an IP address to one device instance at a time). You should delete one of the entries to resolve the issue.

Port status may be unknown when:

  • A port has been recently added and Entuity has not yet completed creation and population of associated streams. The amount of time this takes depends on the size of the install, whether DSKernelStatic has recently been restarted and how many objects have recently been modified or created.
  • The administration status is disabled.
  • An SNMP failure has occurred, including authentication or access control issues, preventing Entuity from determining the port state. For example the device is not responding to SNMP, or the port has been removed from the device but discovery has not yet detected this and updated the inventory. As such, SNMP requests for information about the port are unsuccessful.
