Use the configuration wizard of the Alert management system to define a new NAM alert.
Before you begin
We assume that you have the latest version of the
- NAM Probe added and configured in the NAM Console.
- NAM Server added and configured in the NAM Console and connected to your NAM Probe.
- NAM Console installed.
The new alerts that you can define in NAM operate on a provided set of predefined metrics, or on expressions combined of such metrics. After they are defined, they are easy to modify and use, and they execute quickly: up to 1,000 alert definitions can be processed in one monitoring interval.
Alert basic settings
To create an alert, first select the alert type, specify the alert name, and describe the function and purpose of the alert.
Open the Alert management screen.
On the Alerts tab, User-defined tab, click the Add alert button.
The alert definition wizard opens to the Alert basic settings page.
Select an Alert type from the list.
Each alert type has a predefined set of dimensions and metrics that make it easier for you to configure the alert triggering conditions.
- Real user performance (probe)
These alerts monitor traffic between a client and a server. They are based on traffic monitored by NAM Probe, including the elements that are configured on the NAM Server: applications, transactions, tiers, regions, areas and sites.
- Synthetic Monitoring alert This alert monitors synthetic traffic available through NAM - Synthetic Monitoring integration.
- Application user experience
This alert monitors application user experience for all measurement sources: probe, browser, enterprise, backbone synthetic, last mile and private last mile synthetic.
- Internetwork traffic
These alerts monitor traffic coming in and going out of a specific site.
- Network link
These alerts monitor link utilization.
- Citrix/WTS hardware
These alerts monitor the performance of Citrix servers or Windows Terminal Services (for example, the number of active or open sessions).
- Enterprise Synthetic and sequence transactions
These alerts monitor transactions and track the HTTP-based software service activity of synthetic agents and standard users. They are based on traffic monitored by NAM or Enterprise Synthetic.
Specify the Alert name.
Make the name easy to find in searches and sorts.
Specify the Alert description.
Make the description useful to other people (or to you in the future).
In the list of addresses, select the servers reporting traffic to which the new alert will be applied.
By default, all available report servers are selected, so you just need to clear the servers to which this alert does not apply.
This is not the same as enabling or disabling a definition on a device:
- When you disable an alert on a device, it is still available on the device, in that you can enable it again.
- When you clear the assignment to a device, the definition is removed from the selected device.
Click Next to specify detector settings for the new alert.
