Namespace

Supported version

5.0.0-beta +

Background

SkyWalking is a monitoring tool, which collects metrics from a distributed system. In the real world, a very large distributed system includes hundreds of application, thousands of application instance. In that case, more likely, more than one group, even than one company are maintaining and monitoring the distributed system. Each one of them takes charge of different parts, don't or can't share there metrics.

Namespace is proposal from this.It is used for tracing and monitoring isolation.

Set the namespace

Set agent.namespace in agent config

# The agent namespace
# agent.namespace=default-namespace

The default value of agent.namespace is empty.

Influence The default header key of SkyWalking is sw3, more in this document. After agent.namespace set, the key changes to namespace:sw3.

The across process propagation chain breaks, when the two sides are using different namespace.

Set namespace in collector

configuration:
  default:
    namespace: xxxxx
