Platform Insights Engine

About PIE

PIE is an on-switch real time root cause analysis application. To keep the service outages in a switch to a minimum, it gives insights about the current issues on the switch and visibility about the potential issues.

The PIE application enables you to:

  • Collect data on a switch periodically or during a failure.

  • Analyze the collected data.

  • Find a root-cause for the issue.

  • Reduce the time to resolve issues.

While the data collection should happen on a switch, the analysis can happen on the switch or off the switch. The collection and analysis can happen either online or offline.

Licensing Requirements

The PIE application does not require licensing information.

Guidelines and Limitations

The following are the general guidelines and limitations:

  • All the data that is collected in EventDB is not written to persistent storage. Therefore, data is lost when the system is restarted, switched-off, or reloaded unexpectedly.

PIE Application

The PIE application is implemented as an independent process. It has an internal client which implements a set of insight engines. The actual engine logic is component specific. The internal PIE client provides a simpler way to plugin new insight engines.

PIEs subscribe to events they can analyze. The PIEs analyze raw data and generate insights, such as root cause analysis, about the event. The insights are published back to the broker as new events, which could be used for analysis in other PIEs.

The following list describes the PIEs:

Link Flap PIE

The link flap PIE analyzes link flap events published by user space drivers (USDs) and determines the root cause for a link flap. The PIE publishes the root cause analysis insight to the broker. Link flap events are published by the USDs (PIE client) when a link flaps. The USDs collect all of the relevant data from the ASIC and USD that is required for root cause analysis and publish the data to the broker. The link flap PIE analyzes the data and arrives at the most probable root cause for the flap.

Link Down PIE

The link down PIE finds the root cause for a link not coming up. The USD collects data about an interface when the interface is configured to be up, but the interface's operating state is not up. This data is published to the PIE application. The link down PIE subscribes to these events, receives the data from the broker, and analyzes the data to find the root cause.

Optics PIE

The optics PIE is a continuous monitoring engine that performs a time series analysis of the DOM data collected at regular intervals. By tracking various parameters in the DOM over a period, the PIE arrives at a metric to describe the state of optics for each optical port. The metric is an insight about the trending health of an optical transceiver.

SSD PIE

The SSD PIE provides a mechanism to debug high SSD usage. This PIE provides the top 10 process usage information.

CPU PIE

The CPU PIE provides a mechanism to debug high CPU usage. This PIE provides the top 10 processes that use the most CPU. The data is collected periodically to have a history of top 10 users of CPU usage.

Sensor PIE

The sensor PIE provides a mechanism to debug issues with the temperature sensors by maintaining a history of temperature sensor readings for the past 30 days. The PIE enables system environment readings (PSU, fan, and sensor) to be correlated and derives an insights metric.

Memory PIE

The memory PIE monitors the memory usage of the box. This PIE finds the top 10 users of memory and provides the data collection for detecting memory leaks.

PSU PIE

The PSU PIE monitors the health of the PSU and predicts if the PSU will have a failure. This PIE analyzes the relationship between power, voltage, and current, and captures the hardware state periodically.

Fan PIE

The fan PIE monitors the health of the fans. This PIE analyzes the relationship between pulse width modulation (PWM) and RPM, and makes it easier to find fans that have failed.

PIE Information Model

The following table provides the descriptions for the PIE information parameters:

Table 1. PIE Information Model

Information

Description

Event

A piece of information exchanged by clients associated with a timestamp.

Event ID

A unique identity number to identify an event in the database.

Event Class

An event class identifies the type of event.

Client ID

A Client ID identifies a PIE client.

Source ID

A Source ID identifies a logical source of an event.

Event Meta Data

Metadata consists of the event. It consists of Event ID, Class ID, Source ID, timestamp, and event data length. It is common to all events.

Event Data

The raw data collected by the source or the insight data is published by PIE.

Internal Commands for Broker and Publisher
