Monitoring direct collection from the Device Manager
This section explains monitoring the direct collection of device data using the Device Manager, which you access by choosing Configure > Device Manager.
Monitoring collection status from the Device Table
In the Device Manager you can determine the SNMP and WMI collection status by doing the following:
• Perusing the columns of the Device Table
• Using the Views filter
Perusing the columns of the Device Table
You can determine device status by scrolling through the column headings in the Device Table. For example, to see if a device is active, you can check the Active column the Device Table.
View SNMP collection status columns
To view the SNMP collection status for a device, review the relevant columns in the Device Table listed in the following table:
SNMP columns of interest in the Device Manager
Description
View collection history
Active
(Check, or blank) This must be set for CLI Collection to occur.
Device Name
Unique name of this device in the Device Manager; the same as System Name unless you change it.
Latest SNMP Status
(Green Check, Red X, or Gray Question Mark)
If Red, at least one of CLI Connection, CLI Login, and CLI Commands must be Red.
If Gray, the next three must be Gray.

View WMI collection status columns
To view the WMI collection status for a device, review the relevant columns in the Device Table listed in the following table:
 
WMI columns of interest in the Device Manager

(Check, or blank) This must be set for WMI Collection to occur.

Using the Views filter
The Views filter, located in the left-most frame of the Device Manager, is a powerful tool that supports quick monitoring and troubleshooting by vectoring into the Device Table with filter options.
If, for example, you wanted to see if any WMI devices failed collection, you would click that box in the View menu and only those WMI devices that failed collection would appear in the Device Table.
You can then drill-down to the device page by clicking the Device Name, as well as check the entire WMI collection history as explained in Viewing CLI, SNMP, and WMI collection history or continue to filter WMI views for additional troubleshooting information.
