TIS Plus Glossary and Definitions

Core Concepts

Organization

In TIS Plus, the Organization represents the top-level entity that contains all your observability data and settings. It's the root of the object hierarchy in the TIS Plus system.

Workspace

A workspace in TIS Plus is a logical grouping of services and their associated observability data. Workspaces can span multiple namespaces and clusters, allowing you to organize your services based on your application structure or team boundaries.

Service

A Service in TIS Plus context is a network-addressable application component that can be observed and monitored. It typically corresponds to a Kubernetes Service, but can also represent other types of services in your infrastructure.

Workload

A workload represents an individual instance of a service, such as a Kubernetes pod or a VM-based application instance. TIS Plus collects observability data at the workload level, allowing for detailed insights into service behavior.

Observability Components

Metrics

Metrics are numerical measurements collected over time. In TIS Plus, metrics provide quantitative data about your services' performance, resource usage, and behavior.

Traces

Traces in TIS Plus are records of requests as they flow through your distributed system. They help you understand the path of a request and identify performance bottlenecks across service boundaries.

Logs

Logs are time-stamped records of discrete events that happen in your system. TIS Plus collects and aggregates logs from your Istio-enabled services to provide context for troubleshooting and analysis.

Service Topology

The Service Topology in TIS Plus is a visual representation of how your services are connected and interacting with each other. It's generated based on the observability data collected from your Istio mesh.

Architectural Components

TIS Plus Management Plane

The TIS Plus Management Plane is the hosted, central component of the TIS Plus system. It's responsible for data aggregation, analysis, and presentation through the user interface.

TIS Plus Control Plane

The TIS Plus Control Plane is a lightweight component deployed in your Kubernetes clusters. It's responsible for collecting observability data from your Istio mesh and securely transmitting it to the TIS Plus Management Plane.

Istio

Istio is the service mesh that TIS Plus integrates with to provide observability. TIS Plus works with your existing Istio deployments, collecting the rich telemetry data that Istio generates.

Envoy Proxy

Envoy is the high-performance proxy used by Istio. In the context of TIS Plus, Envoy proxies (deployed as sidecars) generate much of the raw observability data that TIS Plus collects and analyzes. Data Collection and Analysis

Service Registry

The Service Registry in TIS Plus is a comprehensive list of all services detected in your Istio mesh. It's used to provide context for the observability data and to generate the service topology.

Data Aggregation

Data Aggregation in TIS Plus refers to the process of collecting and combining observability data from multiple sources (clusters, services, workloads) to provide a unified view of your system's behavior.

Metric Dashboard

A Metric Dashboard in TIS Plus is a customizable view that displays relevant metrics for your services. TIS Plus provides pre-configured dashboards and allows you to create custom ones to suit your needs.

Trace Analysis

Trace Analysis in TIS Plus involves examining distributed traces to understand request flows, identify bottlenecks, and debug issues across service boundaries.

Log Correlation

Log Correlation in TIS Plus is the process of connecting log entries with related metrics and traces, providing context for events and facilitating root cause analysis.

User Interface Components

Service Graph

The Service Graph in TIS Plus is an interactive visualization of your service topology, showing service dependencies and traffic flow based on the collected observability data.

Trace View

The Trace View in TIS Plus provides a detailed breakdown of individual traces, showing the sequence of spans across services and helping identify performance issues.

Metric Explorer

The Metric Explorer in TIS Plus is a tool for querying and visualizing metrics data, allowing you to create custom charts and investigate performance trends.

Log Viewer

The Log Viewer in TIS Plus provides a centralized interface for searching, filtering, and analyzing logs from across your Istio-enabled services.
