Analytics & Threshold Configuration

  1. Navigate to the Analytics & Threshold ConfigurationPage:

    1. Click the Waffle Icon.

    2. Click AI Ops > Analytics & Incidents.

    3. In the Management page, click the Hamburger Icon, then click Analytics & Threshold Configuration.

This page lets you view and configure the settings that determine when and how Riverbed IQ Ops recognizes network behavior as indicators. Indicators are the fundamental building blocks of incidents.

A policy controls how the Riverbed IQ Ops data pipeline creates indicators, and, therefore, incidents. Upon installation, IQ Ops has a number of built-in policies in place that are configured according to best practices for monitoring networks and which measurements merit being called to your attention in the form of an incident. What merits being called to your attention is a subjective, user/network-defined decision, so IQ Ops provides the ability to override some policies with user-configurable settings. A single policy applies a rule to a measurement on a network entity.

The Analytics & Threshold Configuration page comprises three sections:

  1. Devices

  2. Interfaces

  3. Applications

Each section has a set of relevant metrics that you can enable/disable. In addition, you can configure thresholds.

Network Devices

  • Device Status [Status Change]

  • Device Uptime [Uptime Reset]

Network Interfaces

  • Interface Status [Status Change]

  • In Packet Drops Rate [Baselining]

  • In Packet Error Rate [Baselining]

  • In Utilization [Baselining]

  • In Utilization [Threshold]

  • Out Packet Drops Rate [Threshold]

  • Out Packet Error Rate [Threshold]

  • Out Utilization [Baselining]

  • Out Utilization [Threshold]

Application + Location (i.e., application “MS-Exchange” in location “Branch Office Denver”)

  • Activity Network Time [Dynamic Threshold]

  • Activity Response Time [Dynamic Threshold

  • % Failed Connections [Threshold]

  • MOS [Threshold]

  • Page Load Network Time [Dynamic Threshold]

  • % Total Retrans [Threshold]

  • Throughput (VoIP) [Baselining]

  • User Response Time [Baselining]

  • Unique Critical Health Events [Baselining]

  • Unique Major Health Events [Baselining]

  • % Hang Time [Bounded Dynamic Threshold]

Edit a Static Threshold Value

To edit a static threshold value, click Edit to open the Edit Static Threshold dialog box.

Specify the value at which to generate an indicator from this threshold and the number of measurements to use. You can create an indicator based on a single measurement of the metric, for some number of consecutive measurements, or for N out of M measurements. For example, specifying "2 out of 3" means that the rule must violate for 2 of the last 3 measurements for an indicator to be created. N and M default to 1. M has a maximum value of 10. N must be <= M. If M > 1, N must be > 1 also.

Configure Baseline Settings

To configure baseline settings, click Edit for a metric that uses baselining to open the baseline configuration dialog box.

Baseline configuration includes the following settings:

  • Deviation parameters: The percentage deviation in the baselining parameters can be toggled on and off. At least one deviation parameter must be enabled. The user interface validates this requirement.

  • Metric name and unit: The metric name and the unit of the required minimum deviation are automatically adjusted based on the metric unit in use.

  • Granularity: The granularity setting (for example, 15 mins) represents the time interval used for baselining and must be adjusted based on what Analytics supports.

  • Validation: All numeric values must be positive numbers.

Configure Dynamic Threshold Settings

To configure dynamic threshold settings, click Edit for a metric that uses dynamic threshold to open the dynamic threshold configuration dialog box.

Dynamic threshold configuration includes the following settings:

  • Required minimum deviation: The metric name and the unit of the required minimum deviation are automatically adjusted based on the metric unit in use. This value must be a positive number.

  • Probability: The probability value can be entered as a percentage or adjusted using a slider. When sent to Analytics, the probability is automatically converted to a decimal number between 0 and 1 (exclusive). You can either type a number in the field with any precision, which updates the slider, or move the slider, which updates the number field. The probability must be strictly greater than 0 and strictly less than 100.

  • Validation: The required minimum deviation must be positive. The probability must be strictly higher than 0 and strictly lower than 100.

Configure Bounded Dynamic Threshold Settings

To configure bounded dynamic threshold settings, click Edit for a metric that uses bounded dynamic threshold to open the bounded dynamic threshold configuration dialog box.

Bounded dynamic threshold configuration includes the following settings:

  • Required minimum deviation: The metric name and the unit of the required minimum deviation are automatically adjusted based on the metric unit in use. This value must be a positive number.

  • Probability: The probability value can be entered as a percentage or adjusted using a slider. When sent to Analytics, the probability is automatically converted to a decimal number between 0 and 1 (exclusive). You can either type a number in the field with any precision, which updates the slider, or move the slider, which updates the number field. The probability must be strictly greater than 0 and strictly less than 100.

  • Validation: The required minimum deviation must be positive. The probability must be strictly higher than 0 and strictly lower than 100.
