Managing Realtime Monitors

When a device is configured for monitoring, the data retrieved form these devices are displayed in the form of a realtime monitor. The following lists several procedures to create and manage realtime monitors:

•	Creating a Realtime Monitor

•	Managing Templates for Realtime Monitors

Creating a Realtime Monitor

The Manage Realtime Monitor Dialog enables you to create custom realtime monitors.

1	From the Net Monitor page, select the device(s) for which you wish to create a realtime monitor.

2	In the menu bar, go to SNMP > SNMP Manage Realtime Monitors.

 

The SNMP Manage Realtime Monitors page displays.

 

 

3	Click on the left side of the screen (under Realtime Monitors) to add a new realtime monitor.

4	Add a friendly name for the new monitor in the Monitor Name field.

5	If you wish to save the new monitor as a template for future use, select Save as template. Then, add a friendly name for the template.

6	Choose your display type and chart style as follows:

 

 

Table 61. Display/ Chart types

Display Type	Table: Displays data in a tabular format. Graph: Displays data in a graphical format.
Chart Style Used only when display type is set to graph.	Area: Generates graph in area format. Bar: Generates graph in bar format. Line: Generates graph in line format. Plot: Generates graph in plot format. Pie: Generates graph in pie format. Stacked Area: Generates graph similar to area format, with multiple areas stacked upon each other. Stacked Bar: Generates graph similar to bar format, with multiple bars stacked upon each other.

7	Navigate to the MIB Tree list and select the OIDs you wish to add.

8	In the Middle of the screen, select your preferences as follows:

 

 

Table 62. Available preferences

Add selected OIDs*	Individually: Add OID(s) as individual elements. As a group: Add multiple similar OIDs as one single element.
Add Type	Add To: Add OID(s) to an existing Element. Insert At: Add OID(s) as a new element in the specified location. Append: Append OID(s) to the end of the element list.

NOTE: It is important that the elements present in a Realtime Monitor Template contain OIDs that are present in the devices that the template is applied to. Applying a template which contains un-relevant OIDs can produce unexpected results.

9	Click on the right side of the screen (under MIB Tree) to add the selected MIB(s) to the Elements list.

TIP: Alternate ways of adding a MIB to the Elements list include double-clicking the MIB and dragging and dropping the MIB from the MIB Tree into the Elements list.

10	Enter a friendly name for the element you just added by double-clicking the display name field corresponding to the new element.

11	Specify a threshold value for the alert monitor in the Threshold field corresponding to the new element.

12	Click Apply to save changes and create the realtime monitor.

Managing Templates for Realtime Monitors

A set of Realtime Monitor templates are available for every appliance type the GMS manages, including UMH and Windows. This section allows the user to manage the two types of templates in the system: User-defined and System-Defined. User-defined templates are created from other Realtime Monitors by selecting Save as Template. User-defined templates can be edited or deleted. For user friendliness, system-defined templates are created as Factory Default templates. Unfortunately, these templates are read-only and cannot be edited or deleted.

Users can manage factory templates by completing the procedures that follow:

1	Navigate to the SNMP > SNMP Manage Realtime Monitor Templates screen.

 

 

2	The list of available Realtime Monitor Templates appears on the left side of the screen. Select the template you want applied to the device.

 

 

3	Edit the existing name in the Monitor Name field.

4	Choose your display type and chart style as follows:

 

 

 

Table 63. Display type/chart style selection

Display Type	Table: Displays data in a tabular format. Graph: Displays data in a graphical format.
Chart Style Used only when display type is set to graph.	Area: Generates graph in area format. Bar: Generates graph in bar format. Line: Generates graph in line format. Plot: Generates graph in plot format. Pie: Generates graph in pie format. Stacked Area: Generates graph similar to area format, with multiple areas stacked upon each other. Stacked Bar: Generates graph similar to bar format, with multiple bars stacked upon each other.

5	Navigate to the MIB Tree list and select the OIDs you wish to add.

6	In the Middle of the screen, select your preferences as follows:

 

 

 

Table 64. Available preferences

Add selected OIDs*	Individually: Add OID(s) as individual elements. As a group: Add multiple similar OIDs as one single element.
Add Type	Add To: Add OID(s) to an existing Element. Insert At: Add OID(s) as a new element in the specified location. Append: Append OID(s) to the end of the element list.

NOTE: It is important that the elements present in a Realtime Monitor Template contain OIDs that are present in the devices that the template is applied to. Applying a template that contains irrelevant OIDs can produce unexpected results.

Creating a Realtime Monitor From a Template

To set up a realtime monitor using one or more templates, complete the following steps:

1	Select the device(s) you wish to create a realtime monitor for.

2	In the menu bar, go to SNMP > SNMP Apply Realtime Monitor Templates.

 

3	Select the templates (ctrl-click for multiple selections) you wish to use for monitoring the selected device(s).

NOTE: Multiple templates can be selected by holding Ctrl + selecting the templates. The Filter search bar allows you to narrow the list of templates. Do an exact match search by using double quotation marks, for example “template name,” or search with no quotation marks to search through multiple keywords.

 

 

4	Click Apply to create the Realtime Monitor.

Viewing Realtime SNMP Monitoring Information

GMS NetMonitor allows you to view realtime monitoring data for one or multiple devices simultaneously. Data represented in these charts shows the last hour of activity for the specified node. To view the realtime monitoring information for one or more devices, complete the procedures that follow:

1	Select the device(s) you wish to monitor from the GMS NetMonitor main status screen (Ctrl-click for multiple devices).

2	In the menu bar, select SNMP > SNMP Realtime Monitor Status.

3	In the Realtime Monitors window, select one or more nodes to monitor. The appropriate graphs and or tables are loaded into the monitoring window on the right side of the screen.

NOTE: Data in the monitoring windows is refreshed automatically based on the auto-refresh interval specified in NetMonitor Preferences. While you might do a manual refresh of the graphs and charts, it is not necessary.

 

4	To display historical charts (daily, weekly, monthly) for a node, double-click on the desired realtime graph in the monitoring window on the right side of the screen.

 

NOTE: Only one history chart window might be opened at a time. It is possible, however, to display historical charts for multiple nodes by selecting the charts you wish to view with Ctrl-click, and then clicking at the top right side of the screen.
