Using the Device Manager Page

After running discovery for the first time, you can view the list of discovered devices on the Device Manager page (Registry > Devices > Device ManagerDevices > Device Manager).

The list of devices on the Device Manager page matches the list of devices on the Devices page, but the Device Manager page includes additional functionality, which is covered in this section.

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 the menu options, click the Advanced menu icon ().

This section includes the following topics:

Viewing the List of All Devices

After running discovery for the first time, you can view the list of discovered devices in the Device Manager page. To access the Device Manager page, go to Devices > Device Manager (or Registry > Devices > Device Manager in the classic user interface):

The Device Manager page displays the following information about each device:

To sort the list of devices, 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. For devices running SNMP or with DNS entries, the name is discovered automatically. For devices without SNMP or DNS entries, the device's IP address will appear in this field.

Device Hostname. For devices that are discovered and managed by hostname (instead of IP address), this field displays the fully qualified hostname for the device.
IP Address. The IP address of the device.
Device Category. The category assigned to the device. Categories include servers, routers, switches, firewalls, and printers, among others. The category is automatically assigned during discovery, at the same time as the as Device Class/Sub-Class.
Device Class/Device Sub-Class. The manufacturer (device class) and type of device (sub-class). The Device Class/Sub-Class is automatically assigned during discovery, at the same time as the Category.
DID. Device ID. This is a unique number automatically assigned to the device by SL1.
Organization. The Organization to which the device is assigned.
Current State. Condition of the device, based upon events generated by the device. Condition can be one of the following:

Critical. Device has a serious problem that requires immediate attention.
Major. Device has a problem that requires immediate attention.
Minor. Device has a less-serious problem.
Notice. Device has an informational event associated with it.
Healthy. Device is running with no problems.

The appearance of the Current State field depends upon the value of the Show Severity Badges field in your user preferences. If the Show Severity Badges field is enabled, the value in the Current State column will be displayed as a color-coded badge. If the Show Severity Badges field is not enabled, the value in the Device Name column and the value in the Current State column will be painted with the severity color.

Collection Group. Specifies the collector group to which the device belongs. Collector Groups are defined in the Collector Group Management page (System > Settings > Collector Groups) and specify a primary Data Collector and an optional failover collector. A Data Collector server is the appliance that gathers data from the device. For All-In-One Appliances, this field displays only the built-in Collector Group (and any virtual Collector Groups).

Collection State. Specifies the current condition of data collection for the device. Collection state can be one of the following:

Active. SL1 is collecting data from the device.
Unavailable. SL1 cannot connect to the device, and will not collect data from the device until the device becomes available. A physical device falls back to executing the availability ping every five minutes, unless you have critical ping enabled. Component devices get their availability calculated by the component discovery Dynamic Application of the parent device.
User-Disabled. SL1 is not currently collecting data from the device because the user has disabled collection.
System-Disabled. SL1 is not currently collecting data from the device because the system has disabled collection.
Maintenance. SL1 is not currently collecting data from the device because it is currently in scheduled maintenance mode.
User-Initiated-Maintenance. SL1 is not currently collecting data from the device because it has manually been put into maintenance mode by a user.
Component Vanished. The component device has vanished, i.e. is not currently being reported by its root device. SL1 cannot collect data from the device at this time.

Depending on the circumstances, more than one collection state might appear for a single device. For example, if a device is in a scheduled maintenance mode, the Collection State might be Unavailable / Maintenance / System-Disabled.

SNMP Credential. The primary credential used by SL1 to retrieve SNMP information about the device.

NOTE: Your organization membership(s) might affect the display in the SNMP Credential column. For details, see the Discovery and Credentials section.

SNMP Version. The version of SNMP used by the SNMP Credential.
SL Agent. Indicates if the SL1 Agent is installed on the device. If the agentis installed on the device, the SL Agent column displays a gear icon that can be used to access agent settings. For more information about editing Agent settings, see the Monitoring Using the Agent section. The SL Agent column does not appear on the Device Manager page by default. For more information about adding or removing columns on the Device Manager page, see the Device Manager Preferences section.
Tools. Displays icons for managing devices. The choices are:

Special Characters

You can include the following special characters to filter by each column except those that display date and time:

When searching for a string, SL1 will match substrings by default, even if you do not include any special characters. For example, searching for "hel" will match both "hello" and "helicopter". When searching for a numeric value, SL1 will not match a substring unless you use a special character.

String and Numeric

, (comma). Specifies an "OR" operation. Works for string and numeric values. For example:

"dell, micro" matches all values that contain the string "dell" OR the string "micro".

& (ampersand). Specifies an "AND " operation. Works for string and numeric values. For example:

"dell & micro" matches all values that contain both the string "dell" AND the string "micro", in any order.

! (exclamation point). Specifies a "not" operation. Works for string and numeric values. For example:

NOTE: You can also use the "!" character in combination with the arithmetical special characters (min-max, >, <, >=, <=, =) described below.

* (asterisk). Specifies a "match zero or more" operation. Works for string and numeric values. For a string, matches any string that matches the text before and after the asterisk. For a number, matches any number that contains the text. For example:

"hel*er" would match "helpers" and "helicopter" but not "hello".

"325*" would match "325", "32561", and "325000".

"*000" would match "1000", "25000", and "10500000".

? (question mark). Specifies "match any one character". Works for string and numeric values. For example:

"l?ver" would match the strings "oliver", "levers", and "lover", but not "believer".

"135?" would match the numbers "1350", "1354", and "1359", but not "135" or "13502"

String

^ (caret). For strings only. Specifies "match the beginning". Matches any string that begins with the specified string. For example:

"^sci" would match "scientific" and "sciencelogic", but not "conscious".

"^happy$" would match only the string "happy", with no characters before or after.

"!^micro" would match all values that do not start with "micro".

"!^$" would match all values that are not null.

"!^" would match null values.

$ (dollar sign). For strings only. Specifies "match the ending". Matches any string that ends with the specified string. For example:

"ter$" would match the string "renter" but not the string "terrific".

"^happy$" would match only the string "happy", with no characters before or after.

"!fer$" would match all values that do not end with "fer".

"!^$" would match all values that are not null.

"!$" would match null values.

NOTE: You can use both ^ and $ if you want to match an entire string and only that string. For example, "^tern$" would match the strings "tern" or "Tern" or "TERN"; it would not match the strings "terne" or "cistern".

Numeric

min-max. Matches numeric values only. Specifies any value between the minimum value and the maximum value, including the minimum and the maximum. For example:

"1-5 "would match 1, 2, 3, 4, and 5.

- (dash). Matches numeric values only. A "half open" range. Specifies values including the minimum and greater or including the maximum and lesser. For example:

"1-" matches 1 and greater. So would match 1, 2, 6, 345, etc.

"-5" matches 5 and less. So would match 5, 3, 1, 0, etc.

> (greater than). Matches numeric values only. Specifies any value "greater than". For example:

">7" would match all values greater than 7.

< (less than). Matches numeric values only. Specifies any value "less than". For example:

"<12" would match all values less than 12.

>= (greater than or equal to). Matches numeric values only. Specifies any value "greater than or equal to". For example:

"=>7" would match all values 7 and greater.

<= (less than or equal to). Matches numeric values only. Specifies any value "less than or equal to". For example:

"=<12" would match all values 12 and less.

= (equal). Matches numeric values only. For numeric values, allows you to match a negative value. For example:

"=-5 " would match "-5" instead of being evaluated as the "half open range" as described above.

Examples

"!dell" matches all values that do not contain the string "dell".
"!^micro" would match all values that do not start with "micro".
"!fer$" would match all values that do not end with "fer".
"!^$" would match all values that are not null.

Availability for Component Devices

The following rules apply to the availability state for component devices:

Component devices can use a Component Identifier to monitor availability. However, in a tree of component devices, some component devices might have a component identifier for availability and others might not. For example, suppose a component device has a component identifier for availability, and SL1 considers that component device "unavailable". All the descendents of that component device that do not have their own component identifier for availability will be considered unavailable. As soon as SL1 finds a descendent with its own component identifier for availability, SL1 stops checking that descendent and its descendents for availability. Component devices without their own component identifier for availability inherit their availability from their nearest ancestor that has a component identifier for availability.

For trees that include merged devices, to include both hardware devices and component devices, SL1 skips over the hardware devices and allows them to use a network-based protocol to determine availability. For example, suppose you have a tree like this:

Grandparent device is a component device with a component identifier for availability. SL1 has determined that the grandparent device is unavailable.

Child device is a hardware device that uses ICMP and ping to determine availability. When SL1 evaluates the grandparent's component identifier, SL1 skips over this device. ICMP and ping determine the availability of this device.
Grandchild device is a component device that does not have its own component identifier for availability. When SL1 evaluates the grandparent's component identifier, SL1 assigns the grandparent's availability to this grandchild device.

If all the hosts in a cluster are powered off or unavailable in a VMware system, both the hardware-based hosts and the associated component devices will display the value Unavailable in the Collection State column. When at least one host in the cluster becomes available, some or all of the associated component devices will also become available.

Viewing Child Devices

You can view component child devices of a root device in the Device Components page. If that child device also serves as a root device, you can also view its component child devices, and so forth. To view component child devices for root devices:

Go to the Device Components page (Devices > Device Components).
In the Device Components page, find the root device for which you want to view its component children. Select its plus sign icon ().
The device will be expanded to display the component child devices below the root device.

You can select the plus sign icon for each component child device that also serves as a root device. To collapse the component child devices, select their minus sign icon ().

Filtering the List of Component Devices

You can filter the list on the Device Components page by one or more parameters. Only component devices that meet all the filter criteria will be displayed in the Device Components page.

To filter by each parameter except Current State, enter text into the desired filter-while-you-type field. The Device Components page searches for component devices that match the text, including partial matches. By default, the cursor is placed in the left-most filter-while-you-type field.

Bulk Merging and Unmerging of Devices

If your SL1 system includes a physical device and a component device that both represent the same device, you can merge those device records into a single record for easier monitoring. Merging does not remove, replace, or add any data; merging simply groups data together.

There are several benefits to merging physical and component devices:

Merging consolidates the devices and their data—device fields, values, graphs, behaviors, and other user interface elements—providing you with a single set of data for the device.
Merging reduces the number of duplicated events and administrative tasks.
Merged devices consume only a single device license.

For example, you might discover a virtual machine device component representing a server, and then later discover an IP-based device from the same server. To prevent duplicate events from occurring for the same server, minimize administrative tasks, and prevent a negative impact on your licensing by inflating the number of devices being monitored by SL1, you could merge the virtual machine component and the corresponding IP-based device into a single device record.

You cannot merge a component device with a physical device that acts as the root device for a dynamic component map (DCM) tree.

When you merge a physical device and a component device, the device record for the component device no longer displays in the user interface, while the device record for the physical device displays in user interface pages that previously displayed the component device. For example, the physical device is displayed instead of the component device in the Device Components page and the Component Map page. All existing and future data for both devices will be associated with the record for the physical device.

Merged devices can be unmerged back into individual device records, if needed.

The Device Manager page (Devices > Device Manager) contains options for the bulk merging or unmerging of multiple pairs of physical and component devices. These features are convenient if you have a large number of devices you want to merge or unmerge in a single session.

You can merge only two individual devices together into a single merged device. To do so, you must have user permissions that allow merging and unmerging on both devices. For more information about user access permissions, see the section on Assigning Access Hooks.

When you merge devices, active events associated with the component device will be set to "cleared." The cleared events will not be associated with the physical device. If the devices are unmerged, the cleared events cannot be moved back to the component device.

Merging devices also merges the log data from each device. The log data cannot be unmerged later.

Use consistent device hostnames to make device merging easier.

Performing a Bulk Device Merge

If you have a large number of devices to merge, you can perform a bulk device merge, which is more efficient than merging device pairs individually. A bulk device merge enables you to select from multiple pairs of devices—particularly those with matching IP addresses or device names—and choose the pairs to merge.

If you have a small number of physical and component devices that you want to merge, you can merge each pair individually. For more information, see the Merging Individual Devices section.

To perform a bulk device merge:

Go to the Device Manager page (Devices > Device Manager).
Select the Actions menu and then choose Merge Devices.

Because of the potentially large number of devices that could be merged, no results display when the Device Bulk Merge page initially displays. You must select one of the checkboxes or begin typing a name in the Names Contain field for results to display on the page.

On the Device Bulk Merge page:

Select the IP Addresses Match checkbox if you want the page to display a list of devices where the physical device and the component device a have matching IP addresses.

Select the Names Match checkbox if you want the page to display a list of devices where the physical device and the component device have matching Device Names.
If you want the page to display a list of devices that could be merged where the Device Names of the physical device and the component device contain the same character(s), enter those characters in the Names Contain field.

In the Organizations field:

Select Ignored if you do not want to filter the list of devices based on the Organizations assigned to the physical device and the component device.

Select Match if you want to filter the list of devices to include only physical devices and component devices that have matching Organizations.
Select Don't Match if want to filter the list of devices to include only physical devices and component devices that do not have matching Organizations.

In the Classes field:

Select Ignored if you do not want to filter the list of devices based on the Device Classes assigned to the physical device and the component device.

Select Match if you want to filter the list of devices to include only physical devices and component devices that are assigned matching Device Classes.
Select Don't Match if you want to filter the list of devices to include only physical devices and component devices that are assigned non-matching Device Classes.

You can make selections in the Organizations and Classes fields only after you make a selection or entry in the IP Addresses Match, Names Match, and/or Names Contain fields.

The Device Bulk Mergepage displays a list of physical device and component device pairs that match your search criteria. Each numbered row indicates a pair of devices that could be merged.

Select the radio button(s) in the last column of each row of device pairs that you want to merge, then select the Merge button. The radio buttons are grouped per physical device, i.e., you can select only one row for each physical device.

You can select each component device only once for merging. If you attempt to select the same component device in multiple rows, you will receive an error message when you select the Merge button.

A modal window displays that asks you to confirm the merge. Select the Yes button.

SL1 begins merging the selected devices. When the message, "Device Bulk Merge complete" displays, select the Close/Esc button.

To view an updated list of devices that includes your merged devices, select the Reset button on the Device Manager page.

Performing a Bulk Device Unmerge

If you have a large number of devices to unmerge, you can perform a bulk device unmerge, which is more efficient than unmerging device pairs individually. A bulk device unmerge enables you to view a list of merged devices and select all of the devices you want to unmerge.

If you have a small number of devices that you want to unmerge, you can unmerge each pair individually. For more information, see the Unmerging Individual Devices section.

For details on unmerging a vanished device, see the section on Unmerging Vanished Devices.

To unmerge multiple devices:

Go to the Device Manager page (Devices > Device Manager).

Select the Actions menu and then choose Unmerge Devices.

The Device Bulk Unmerge page displays a list of merged devices. Each numbered row indicates a pair of merged devices that can be unmerged. Select the checkboxes in the last column of each row of devices that you want to unmerge, then select the Unmerge button.

A modal window displays that asks you to confirm the unmerging. Select the Unmerge button.

When the message, "Device Bulk Unmerge complete" displays, select the Close/Esc button.

To view an updated list of devices that includes your unmerged devices, select the Reset button on the Device Manager page.
