Interfaces and Networks

This section describes how to view the interfaces and networks for the routers, switches, and firewalls that Skylar One discovers.

Viewing All Interfaces Discovered by the ScienceLogic Platform

During discovery, Skylar One discovers all interfaces on each discovered device. The list of all interfaces is displayed in the Network Interfaces page.

The Network Interfaces page allows you to view a list of all interfaces, view details about each interface, define a monitoring policy for an interface, and view bandwidth reports for each interface.

To view a list of all interfaces discovered by Skylar One:

Go to the Network Interfaces page (Registry > Networks > Interfaces).
The Network Interfaces page displays a list of all network interfaces discovered by Skylar One.
The Network Interfaces page displays the following for each interface.

To sort the list of interfaces, click on a column heading. The list will be sorted by the column value, in ascending order. To sort the list by descending order, click the column heading again.

Device Name. Name of the device where the interface resides.
Port/Sub. Port and sub-port (if applicable) of the interface.

IF Name. The name of the network interface. The auto-name, generated by Skylar One, is device_name:interface_number. You can define a different name in the Interface Properties page.
Tags. Displays a comma-delimited list of descriptive tags that have been manually defined for the interface. Interface tags are used to group interfaces in an IT service policy. To add or edit the tags for an interface, click its wrench icon (). In the Edit Network Interface Tags modal that appears, supply a comma-delimited list of tags in the Tags field, and then click the Save button.
Organization. Organization associated with the network interface. This can be the organization associated with the device where the interface resides, or it can be an organization that has emissary rights to the interface.
Alias. User-defined name assigned to the interface.
MAC Address. A unique number that identifies the interface. MAC Addresses are defined by the hardware manufacturer.
IF Index. A unique number (greater than zero) that identifies each interface on a device. These numbers are defined within the device.

NOTE: If an interface has a status of "down" during initial discovery, Skylar One will discover the interface but assign the interface the default Counter Setting of "32". During re-discovery or nightly auto-discovery, Skylar One will update Counter Setting to "64" if applicable.

State. Specifies whether Skylar One monitors the network interface and collects data about the network interface for reports. Can be either Enabled or Disabled.

Edit Date. Date and time the monitoring policy for the interface was created or last edited. If the interface is using the default monitoring policy, the edit date reflects the date that the interface was discovered by Skylar One.

Viewing Interfaces for a Single Device

In the Device Administration panel for a device, you can view the Device Interfaces page. The Device Interfaces page displays detailed information about each network interface on the device and allows you to define monitoring policies for interfaces on the device. When you define a monitoring policy for an interface, Skylar One will monitor the interface and gather usage data from the interface. Skylar One uses the data retrieved from the interface to generate bandwidth reports for the interface.

In the Device Reports panel for a device, you can view the Interfaces Found page. The Interfaces Found page displays detailed information about each network interface on the device. The Interfaces Found page allows you to view a list of all interfaces on the device, view details about each interface, and view bandwidth usage reports for each interface.

To view details about the network interfaces on a device:

Go to the Device Manager page (Devices > Classic Devices, or Registry > Devices > Device Manager in the classic SL1 user interface).
Find the device for which you want to view the list of network interfaces, then do one of the following:

Click its wrench icon (), followed by the Interfaces tab, to view the Device Interfaces page.
Click the bar graph icon (), followed by the Interfaces tab, to view the Interfaces Found page.

Both pages display icons to represent the interfaces on the device.
The page displays an icon for each interface on the device. Each icon provides a visual overview of the interface.
For details on interface icons, click the Legend button, or in the Actions menu, select Interface Legend. The Interface Legend modal page displays each type of interface icon with explanatory callouts.
When you mouse over the icon for that interface, the Interface Details pop-up window appears. This window displays details about the interface and its current monitoring policy.
The Interface Details pop-up window displays the following about an interface:

Collect Discards. Specifies whether or not Skylar One will collect data about interface discards. Discards occur when an interface receives more traffic than it can handle. Discards can also occur when an interface has been specifically configured to discard. For example, a network administrator might configure a router's interface to discard packets from an unauthorized IP address.
Alerts. Specifies whether or not Skylar One will generate internal collection events for the interface. When disabled, the interface is monitored, but internal collection events are not generated for the interface.
Rollover Alerts. Specifies whether or not Skylar One will generate an event when the counter for the interface rolls over.

NOTE: Rollovers and Rollover Alerts apply only to 32-bit counters and not to 64-bit counters.

IP. IP address and network mask assigned to the interface.
Counter Type. Specifies whether the interface uses a 32-bit counter or a 64-bit counter to measure bandwidth on the interface.

NOTE: If an interface has a status of "down" during initial discovery, Skylar One will discover the interface but assign the interface the default Counter Type of "32". During re-discovery or nightly auto-discovery, Skylar One will update the Counter Type to "64" if applicable.

IANA Type. A string that describes the type of interface, as defined by the standards group Internet Assigned Numbers Authority.
Interface Index. A unique number (greater than zero) that identifies each interface on a device. These numbers are defined by the device.

In the Device Interfaces page, clicking on an interface icon leads to the Interface Properties page, where you can define a monitoring policy for an interface.
In the Interfaces Found page, clicking on an interface icon leads to the Network Bandwidth Usage report in the Device Performance page.

Overview of Network Records

During discovery of an SNMP-enabled device, Skylar One collects information about the network interfaces on that device using the standard IF-MIB. After collecting information about each interface, Skylar One collects information about the IP addresses associated with those interfaces using the standard IP-MIB.

After discovery, Skylar One runs a process that classifies each IP address associated with that device. The classification process calculates the network address by performing a bitwise "AND" operation using the IP address and the network mask. Skylar One determines whether the IP address for the device needs to be associated with an existing network record or whether to create a new network record.

After an IP address is associated with a network record, the interface associated with that IP address appears in the Network Browser page for that network record. To access the Network Browser page for a network record, go to the IPv4 Networks page (Registry > Networks > IPv4 Networks) and select the desired interface icon.

IPv4 Networks

The IPv4 Networks page (Registry > Networks > IPv4 Networks) lists all networks and subnets detected by ScienceLogic auto-discovery and all manually defined (new) networks.

The IPv4 Networks page allows you to easily manage networks and IP addresses. From the IPv4 Networks page, you can view detailed data about the network, keep records of subnets, and determine which IP addresses are in use and which IP addresses are available.

NOTE: Users of type "user" can view only IPv4 networks that are aligned with the same organization(s) to which the user is aligned. Users of type "administrator" can view all IPv4 networks.

Viewing the List of IPv4 Networks

The table in the IPv4 Networks page (Registry > Networks > IPv4 Networks) contains an entry for each network managed by Skylar One.

NOTE: Users of type "user" can view only IPv4 networks that are aligned with the same organization(s) to which the user is aligned. Users of type "administrator" can view all IPv4 networks.

The IPv4 Networks page displays the following about each managed network:
