Monitoring Networks

During discovery, SL1 discovers all IP networks. The list of all networks is displayed in the IPv4 Networks page (Registry > Networks > IPv4 Networks).

The IPv4 Networks page allows you to view a list of all networks, manage networks and IPs, view devices and interfaces in each network, and view maps and reports for each network.

Use the following menu options to navigate the SL1 user interface:

To view a pop-out list of menu options, click the menu icon ().
To view a page containing all of the menu options, click the Advanced menu 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 SL1.

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:

To sort the list of networks, click on a column heading. The list will be sorted by the column value, in ascending order. To sort by descending order, click the column heading again. The Edit Date column sorts by descending order on the first click; to sort by ascending order, click the column heading again.

Network. IP address of the entire network.
Subnet Mask. Subnet mask for the subnet.
Bits. The number of bits used for the network address.
Used/Max. Number of IP addresses discovered and monitored by SL1 and the maximum number of IP addresses allowed in the subnet.
% Used. Percentage of total addresses in the network that have been discovered and monitored by SL1. In the Account Preferences page, you can specify whether or not you want to include empty networks (networks with no devices or interfaces) in the list of networks. These networks will have 0% in the % Used column.
Devs. Number of devices in the subnet.
IFs. Number of interfaces in the subnet.
Collection Group. The collector group associated with the network. For All-In-One Appliances, this field displays only the built-in Collector Group (and any virtual Collector Groups).
Organization. Organization associated with the network.
Net ID. Unique network ID, assigned by SL1.
Creation Date. Date the network was discovered or manually defined.
Edit User. User who created or last edited the network's properties.
Edit Date. Date the network was created or last edited, whichever is later.
Tools. For each network in the table, the following tools are available:

View/Edit Network Properties (). Displays the Network Properties modal page, where you can view and edit the basic properties of an IPv4 network.
Browse Network (). Leads to the Network Browser page. From this page, you can view a list of IP addresses (used and unused) included in a network, a list of devices included in a network, and a list of interfaces included in a network.
View/Edit Aligned Devices (). Leads to the Network Browser page, where you can view a list of devices associated with a network.

View a Network Report (). Opens the Report Creator modal page, where you can specify information to include in the report and the format in which to generate the report.
Add Network to Dynamic Discovery (). Adds the network to the dynamic-discovery queue. SL1 will perform dynamic-discovery on all of the IP addresses in the network and gather information about any devices and interfaces in the network. Leads to the Discovery Control Panel page, with the selected network as the value in the discovery list.
Create a Ticket (). Leads to the Ticket Editor page, where you can create a ticket that will be associated with the selected network.
Delete (). To delete the network, select this checkbox and then click the Delete button. To select all the checkboxes, click the large red check icon.

Filtering the List of Networks

You can filter the list on the IPv4 Networks page by one or more parameters. Only IPv4 subnets that meet all the filter criteria will be displayed in the IPv4 Networks page.

To filter by parameter, enter text into the desired filter-while-you-type field. The IPv4 Networks page searches for IPv4 subnets that match the text, including partial matches. By default, the cursor is placed in the left-most filter-while-you-type field. You can use the <Tab> key or your mouse to move your cursor through the fields. The list is dynamically updated as you type. Text matches are not case-sensitive.

You can also use special characters to filter each parameter.

Filter by one or more of the following parameters:

Network. You can enter text to match, including special characters (comma, ampersand, and exclamation mark), and the IPv4 Networks page will display only subnets that have a matching network IP.
