Set Agent Startup Parameters

Overview

To prevent the agent from overusing server resources and disrupting other services, the agent’s performance is restricted in the log service. If you need to enhance the agent’s collection performance, you can modify the allowed CPU core count threshold for the agent. This document explains how to configure the agent’s startup parameters for both host and Kubernetes (k8s) environments.

Configure scenarios

You can modify the agent’s resource configuration under the following circumstances.

• High log data traffic leads to excessive CPU usage by the agent.
• Log collection delays are observed during query operations.

Set startup parameters in the host environment

1. Open the startup parameter configuration file

• In the Linux environment, the startup parameter configuration file is located under the installation directory/logbeat/logbeat.yml, defaulting to /opt/logbeat/logbeat.yml
• In Windows environments, the startup parameter configuration file is located in C:\Program Files\Baidu\Logbeat\logbeat.yml

2. Adjust startup parameters as necessary.

Example of startup parameter configuration file:

1management:
2  enabled: true
3  token: 1e05de1f-****-****-****-a04963f8e65c
4  token_list: [ ]
5  bls_server_address: https://bls.bj.baidubce.com:8185
6  tasks: [ ]
7max_procs: 1

3. Restart the agent

• In the Linux environment, execute service logbeatd restart or /opt/logbeat/bin/restart.sh

• Windows environment:

  Step I: Stop the agent process: C:\Program Files\Baidu\Logbeat\stop.bat

  Step II: Restart the agent process: C:\Program Files\Baidu\Logbeat\start.bat

Set startup parameters in the k8s environment

In k8s environment, you need to modify the agent configuration file by modifying the configmap

1kubectl edit configmap -n kube-syetem logbeat-global-configmap

Modify startup parameters directly on the CCE platform for CCE containers

1. Log in to Cloud Container Engine Console (CCE)
2. In the left navigation bar, click on the cluster list.
3. On the Cluster List page, click on the desired cluster to open the cluster management page.
4. Select Configuration Management - ConfigMap in the left navigation bar, and locate the corresponding ConfigMap

5. Click Modify to modify the max_procs parameter and confirm for immediate effect
