Monitoring Traditional Servers

This document was translated by GPT-4

# 1. Introduction

DeepFlow supports monitoring of traditional servers. Please note that the DeepFlow Server must be run on K8s. If you do not have a K8s cluster, you can refer to the All-in-One Quick Deployment section to deploy DeepFlow Server first.

# 2. Deployment Topology

# 3. Configuring DeepFlow Server

# 3.1 Update deepflow-server configuration

Check if all server sectors are in the following list of sectors

local_ip_ranges:
  - 10.0.0.0/8
  - 172.16.0.0/12
  - 192.168.0.0/16
  - 169.254.0.0/15
  - 224.0.0.0-240.255.255.255

If not, you need to add the missing server sectors to the local_ip_ranges list in the custom configuration file below.

Modify the values-custom.yaml custom configuration file:

# add
configmap:
  server.yaml:
    controller:
      genesis:
        local_ip_ranges:
          - 10.0.0.0/8
          - 172.16.0.0/12
          - 192.168.0.0/16
          - 169.254.0.0/15
          - 224.0.0.0-240.255.255.255
        # - 7.8.0.0/16  # FIXME: your host all network cidr
      trisolaris:

Update deepflow

helm upgrade deepflow -n deepflow -f values-custom.yaml deepflow/deepflow
## Restart deepflow-server
kubectl delete pods -n deepflow -l app=deepflow -l component=deepflow-server

# 3.3 Create Collector Group

Create a collector group:

deepflow-ctl agent-group create $AGENT_GROUP
deepflow-ctl agent-group list $AGENT_GROUP # Get agent-group ID

Modify the deepflow-agent's configuration file /etc/deepflow-agent.yaml :

controller-ips:
  - 10.1.2.3 # FIXME: K8s Node IPs

Note:

If deepflow-agent cannot start normally due to missing dependency libraries, you can download a statically linked compiled deepflow-agent. Please note that statically linked compiled deepflow-agent has serious performance problems in multi-threading:
