1. Introduction

DeepFlow Agent advanced configuration.

DeepFlow uses a declarative API to centrally manage all agents, while the data collection configuration of agents is uniformly distributed by the deepflow-server to the agents within the corresponding agent-group based on the agent-group-config content.

An agent-group is used to manage the configuration of a group of agents. By specifying vtap-group-id-request in the agent configuration file (opens new window) (K8s ConfigMap or /etc/deepflow-agent.yaml), you can declare the agent-group it belongs to (if not specified, the Default configuration is used by default). Finally, the association between agent, agent-group, and agent-group-config is established through the agent-group-id.

1.1 Common Operations for agent-group

View the agent-group list:

deepflow-ctl agent-group list

Create an agent-group:

deepflow-ctl agent-group create <AGENT_GROUP_NAME>

View the created agent-group-id:

deepflow-ctl agent-group list <AGENT_GROUP_NAME>

1.2 Common Operations for agent-group-config

Refer to the default configuration of agent-group-config, extract the parts that need to be modified, and output them to the <AGENT_GROUP_CONFIG>.yaml file, for example:

global:
  limits:
    max_millicpus: 2000
    max_memory: 4096

1.2.1 Create an agent-group-config

deepflow-ctl agent-group-config create <AGENT_GROUP_ID> -f <AGENT_GROUP_CONFIG>.yaml

1.2.2 View the agent-group-config list

deepflow-ctl agent-group-config list

1.2.3 View the configuration of a specified agent-group-config

deepflow-ctl agent-group-config list <AGENT_GROUP_ID> -o yaml

1.2.4 View all default configurations of agent-group-config

deepflow-ctl agent-group-config example

1.2.5 Update the agent-group-config configuration

deepflow-ctl agent-group-config update <AGENT_GROUP_ID> -f <AGENT_GROUP_CONFIG>.yaml
