Use the Fetching Method Skip Fallback option for component monitors
SAM includes predefined component monitors, comprised of code and scripts, that you can use to assess the status and performance of applications, services, processes, and event on nodes throughout your environment.
SAM application monitor templates are collections of component monitors that you can assign to nodes as "application monitors" that are also called "applications." A single component monitor can be used on its own and applied to a node in an application monitor, or it can be used in multiple templates with other component monitors.
For some component monitor types, you can control how data is collected by adjusting the Fetching Method. For example, if you select WinRM/DCOM as the Fetching Method for a Windows Service Monitor, SAM will try to use WinRM for application polling. If WinRM fails, DCOM is used as the fallback method. Depending on how the component monitor is configured, SAM will try each fallback method, one at a time, until it succeeds
Starting in SAM 2020.2.6, you can disable fallback methods if you know they aren't relevant for certain component monitors in your environment, or you know they will fail. In addition to saving time, adjusting fallback methods can reduce polling loads and improve overall performance, especially in large environments. If the selected protocol fails, no fallback occurs.
The following steps describe how to set the Fetching Method Skip Fallback option for component monitors within an individual application monitor, but you can also adjust it at the template level. Related application monitors inherit settings from parent templates automatically unless you select the Override Template option for an application monitor.
To disable fallback methods for a component monitor in an assigned application monitor:
- Click Settings > All Settings > SAM Settings.
- Click Manage Application Monitors to open the Manage Assigned Application Monitors page.
Click an application monitor to open the Application Details - Summary page.
You can also access application monitors on the Application Summary page. Drill down to the application monitor in the All Applications widget and click it to display details.
- When the list of component monitors appears, select one and click + to expand its details.
- Select a Fetching Method for the component monitor, such as WinRM.
Select the Fetching Method Skip Fallback check box.
- Click either Submit, or Save and Continue Working.
