The Applications page was removed from the 8.14.0 release. All features on previous versions of this page are considered Beta and experimental.
This section describes how to use SL1 to monitor application health for your devices.
Application Health requires either the SL1 Extended architecture (for devices that use SL1 agents) or SL1 Maps on the Database Server, which is also called Maps on CDB (for devices that do not use SL1 agents). The "Extended" architecture uses a Central Database appliance and multiple storage and data nodes. For more information, see the Installation section. The "Maps on CDB" architecture uses the SL1 Maps images bundle installed on the Central Database appliance. For more information, see the Maps section.
Navigation tips for the SL1 user interface:
To access a list of menu options, click the menu icon ().
To view a page containing all of the menu options, click the Advanced menu icon ().
This section includes the following topics:
What is an Application?
An application is a collection of one or more devices running a similar set of software or processes. You can monitor the application health of that set of devices in SL1 to ensure that the software running on those devices is performing the actions the software is supposed to be performing. If you are using the SL1 agent or an agent-related PowerPack to collect data, you can monitor the system processes for a dynamic list of devices.
An application is made up of one or more application components and a status policy:
An application component is a specific group of devices running the software or process you want to monitor with SL1. An application component has process rules for matching processes reported by an SL1 agent. These process rules act as a filter, and an SL1 agent device is only considered to be part of an application component if at least one process rule is currently matching. You can also create an application component made up of devices that do not use the SL1 agent. An application can contain more than one application component, depending on your monitoring needs.
A status policy contains a set of rules that define the availability, health, and risk criteria for the devices you want to monitor.
To navigate to the Applications page, click the Applications icon ():
Monitoring Application Availability, Health, and Risk
On the Applications page you can monitor the availability, health, and risk of your applications and application components. These three values display in the following format and order:
Availability: Displays whether an application can be used. An application is considered unavailable if SL1 is not able to collect data from the application, or if the application is usable or not usable. A value of 0 means an application is unavailable, and a value of 1 means an application is available. Availability uses the following icons:
Health: Displays a "severity" icon that represents a numerical value between 0 and 100, which indicates the current status of an application to show if its health is worsening or improving. In most cases, a higher value is preferred. Health uses the following icons by default:
Risk: Displays a percentage value between 0 and 100 that indicates how close an application is to being in an undesirable state. In most cases, the safest possible risk value is 0%, while the worst risk value is 100%. Risk uses the following settings by default:
These values are computed in this order because SL1 uses Availability values to compute Health while SL1 uses both Availability and Health values to compute Risk.
The Application Investigator Page
When you select an application or an application component from the Applications page (), the Application Investigator page appears:
The Tabs on the Application Investigator Page
The Application Investigator page contains three tabs:
Overview. Displays a "big-number" dashboard version of the most recent Availability, Health, and Risk values for the selected application or application component. This tab also displays a customizable view of the "constituent" components that are part of the application or application component:
For an application, this tab displays a summary tile view similar to a dashboard widget for any application components that belong to an application. Selecting the checkbox on an application component tile will display a list of devices that belong to that application component. You can then select one or more devices to see events for those devices.
For an application component, this tab displays a list of devices that belong to that application component. You can then select one or more devices to see events for those devices.
To view Root Cause Analysis information for a specific application component on an Application Investigator page, click the Actions icon () on the tile for that component. If the Root Cause Analysis option is enabled, you can review data related to troubleshooting for that component. For more information, see Using the Root Cause Analysis Feature.
Application Components or Devices: Displays the application components or devices aligned with the selected application or application component:
For an application, the Application Components tab displays any application components that are currently aligned with that application, along with the process policy associated with that application. On this tab, you can view application component details and add application components to the application.
For an application component, the Devices tab displays any devices that are aligned with that application component. On this tab, you can use the Rules button to specify process rules that are relevant (if that component has devices with the SL1 agent installed on them). You can also dynamically or statically add devices to that application component.
Status Policy. Displays the rules for the status policy that defines the availability, health, and risk for that application or application component. Depending on the thresholds you configured on the Application Thresholds page (Applications > Thresholds), SL1 generates an alert message if a threshold is crossed. On this tab, you can change the policy used by the application or application component, edit an existing policy, and create a new policy. A Default label appears next to the default policy.
The Info Drop-down on the Application Investigator Page
The Info drop-down at the top of the Application Investigator page displays the following:
Owner. The organization that owns the application.
Contact Organization. A contact organization for the application.
Visible Organizations. A list of additional organizations other than the contact organization from which you can monitor devices for applications. This option appears only on Investigator pages for application components.
Contact User. The contact user for the application.
Include devices from visible organizations. This option lets you enable or disable the ability to include devices from other organizations in an application component. This option appears only on Investigator pages for application components.
Click the Edit button to edit the content on all three tabs and to edit the fields on the Info drop-down. You can also edit the application or application component name and the icon associated with the application or component. Click Save to save your changes.
