HDX Insight on NetScaler Application Delivery Management (ADM) allows you to monitor the HDX traffic passing through NetScaler instances. NetScaler ADM allows you to set thresholds on various counters used to monitor the Insight traffic. You can also configure rules and create alerts in NetScaler ADM.
HDX traffic type is associated with various entities such as applications, desktops, gateways, licenses, and users. Every entity can contain different metrics associated with them. For example, application entity is associated with various hits, bandwidth consumed by the application, and response time of the server. A user entity can be associated with WAN latency, DC latency, ICA® RTT, and bandwidth consumed by a user.
The threshold management for HDX Insight in NetScaler® ADM allowed you to proactively create rules and configure alerts whenever the thresholds set are breached. Now, this threshold management is extended to configure a group of threshold rules. You can now monitor the group instead of individual rules. A threshold rule group comprises one or more user-defined threshold rules for metrics chosen from entities such as users, applications, and desktops. Each rule is monitored against an expected value that you enter when you create the rule. In case of users entity, the threshold group can be associated with a geolocation as well.
An alert is generated on NetScaler ADM only if all the rules in the configured threshold group are breached. For example, you can monitor an application on total session launch count and also on application launch count as one threshold group. An alert is generated only if both rules are breached. This allows you to set more realistic thresholds on an entity.
A few examples are listed as follows:
An example of threshold group can be: {Threshold rule 1 + Threshold rule 2}
To create a rule, you must first select the entity that you want to monitor. Then choose a metric while creating a rule. For example, you can select applications entity and then select Total Session Launch count or App Launch Count. You can create one rule for every combination of an entity and a metric. Use the comparators provided (\>, \<, \>=, and \<=) and type a threshold value for each metric.
If you do not want to monitor multiple entities in a single group, you must create a separate threshold rule group for each entity.
When the value of a counter exceeds the value of a threshold, NetScaler ADM generates an event to signify a threshold breach, and an alert is created for every event.
You must configure how you receive the alert. You can enable the alert to be displayed on NetScaler ADM and/or receive the alert as an email or as an SMS on your mobile device. For the last two actions, you must configure the email server or the SMS server on NetScaler ADM.
Threshold groups can also be bound to Geolocations for geo-specific monitoring for user entity.
