TCO Tracing Policy gRPC API

This tutorial demonstrates how to use our TCO Tracing gPRC API to define, query, and manage your TCO policy criteria, used both for spans and logs.

View this page to learn how to use our TCO Optimizer HTTP API to define, query, and manage your TCO policy overrides, used exclusively for logs.

Overview

Tracing policies aim to match spans, which are the fundamental components of a trace. The matching process is carried out based on the rules you define. Those rules can be defined using application/subsystem/operation/service names or by tag names and values. There are various types of matching rules, explained in detail below.

Matching Process

Spans that match all rules in a policy will be assigned the priority level defined in that policy.

Every rule targets a property (e.g. Application) by RuleTypeId.

TagRule targets a tag name and a tag value (e.g. tag name: tags.http.method and tag value: GET).

Examples:

• A rule on Application with the RuleTypeId RULE_TYPE_ID_IS and the name default,app1 will match all spans with application name default or app1.
• A rule on Subsystem with RuleTypeId RULE_TYPE_ID_START_WITH and the name authSer will match all spans with subsystem names that start with authSer.
• A TagRule with the name tags.http.target, RuleTypeId RULE_TYPE_ID_INCLUDES, and the value /api will match all spans that have the tag tags.http.target and a value that contains /api.

Supported API Calls

The API supports the following gRPCs:

• Get Policy
• Create Policy
• Update Policy
• Get Company Policies
• Delete Policy
• Reorder Policies
• Toggle Policy

Notes:

• This API supports both log and tracing policies.
• In some requests, the field source_type_rules appears, containing unique fields for each. The field source_type may also appear, allowing you to decide which type of policies you want to receive or affect.

The API supports the following gRPCs:
