1. Introduction

Advanced configuration of DeepFlow Agent.

DeepFlow uses a declarative API to control all deepflow-agents, and almost all of the deepflow-agent configuration is issued through the deepflow-server. In DeepFlow, the agent-group is a group that manages a set of deepflow-agent configurations. We can specify vtap-group-id-request in the local configuration file of deepflow-agent (K8s ConfigMap, deepflow-agent.yaml on the Host) to declare the group we want to join, or we can directly configure the group to which each deepflow-agent belongs on the deepflow-server (the latter has a higher priority). The agent-group-config and the agent-group correspond one-to-one and are associated through the agent-group ID.

1.1 Common operations of agent-group

View the agent-group list:

deepflow-ctl agent-group list

Create an agent-group:

deepflow-ctl agent-group create your-agent-group

Get the ID of the agent-group just created:

deepflow-ctl agent-group list your-agent-group

1.2 Common operations of agent-group-config

Refer to the agent's default configuration above, select the part you want to modify, create a your-agent-group-config.yaml file and fill in the agent configuration parameters. Note that it must include vtap_group_id:

vtap_group_id: <Your-agent-group-ID>
# write configurations here

1.2.1 Create agent-group-config

deepflow-ctl agent-group-config create -f your-agent-group-config.yaml

1.2.2 Get agent-group-config list

deepflow-ctl agent-group-config list

1.2.3 Get agent-group-config configuration

deepflow-ctl agent-group-config list <Your-agent-group-ID> -o yaml

1.2.4 Get all configurations and their default values of agent-group-config

deepflow-ctl agent-group-config example

1.2.5 Update agent-group-config configuration

deepflow-ctl agent-group-config update -f your-agent-group-config.yaml

1.3 Common Configuration Items

• max_memory: The maximum memory limit of the agent, the default value is 768, in MB.
• thread_threshold: The maximum number of threads for the agent, the default value is 500.
• tap_interface_regex: The agent collects the regular configuration of the network card, the default value is ^(tap.*|cali.*|veth.*|eth.*|en[ospx].*|lxc.*|lo)$, the agent only needs to collect the Pod network card and the Node/Host physical network card.
• platform_enabled: Used when the agent reports resources, for the domain of agent-sync, a DeepFlow platform can only have one domain of agent-sync.
