Foglight Agent Manager 7.3.0 - Foglight Agent Manager Guide

Errors related to Windows WMI and DCOM configuration

If you encounter errors with WMI or DCOM configuration for remote agents, see Configuring Windows Management Instrumentation (WMI) and Configuring Windows Remote Management (WinRM) .

Resolving DATA_COLLECTION_FAILED errors

Credentials that are used by host agents to monitor remote hosts can have a Use Count policy configured through the Management Server browser interface. In such cases, when the number of collections exceeds the Use Count number, the host agent fails and enters the DATA_COLLECTION_FAILED mode. A Use Count policy violation event is also generated on the Management Server and can be viewed in the Monitor Credential Alarms dashboard.

To restart data collection:

•

Delete the Use Count policy associated with the credential, through the Management Server browser interface (Dashboards > Credentials > Manage Credentials > Edit > Policies). For more information about credential management, see the Foglight Administration and Configuration Guide.

Adjusting the maximum polling interval

The Maximum Number of Polls (per minute) property sets the maximum number of polls that Foglight accepts from Agent Manager instances per minute.

In environments with a large number of Agent Manager instances, running Foglight® with the default value of 500 for Maximum Number of Polls (per minute) can increase Agent Manager communication latency to unacceptable levels.

If you are running a large number of Agent Manager instances in your environment, Quest recommends that you change the value of this property so that it is higher than 500 (the default value). Doing so increases the number of polls allowed per minute and decreases the maximum polling interval.

To adjust the Maximum Number of Polls (per minute) setting, in the Foglight browser interface, navigate to Administration > Agents > Agent Properties > FglAM > FglAMAdapter.


	CAUTION: Allowing a higher number of polls per minute increases the polling load on the Management Server. The value of Maximum Number of Polls (per minute) should only be increased on machines and in networks that can handle the increased load.

Advanced system configuration and troubleshooting

This contains platform-specific configuration information for configuring Foglight® Agent Manager on Windows® when using Windows Management Instrumentation (WMI) or Windows Remote Management (WinRM) for remote monitoring access.


	NOTE: WMI and WinRM are two different mechanisms that monitoring agents can use to establish remote connections. In most scenarios, only one of these mechanisms needs to be configured. The preferred mechanism is WinRM because of WMI scalability limitations.
