Agent Configuration

The Agent configuration file is in YAML format.

In the admin frontend, you can modify the Agent's configuration and apply it directly; you can also batch apply options through the API, see the API documentation for details.

Options

• client_secret

  • The client secret used for secure communication with the Dashboard.
  • This parameter must match the configuration in the Dashboard to enable proper communication.

• debug

  • When set to true, enables logging.

• disable_auto_update

  • When set to true, disables the automatic update feature, enhancing system stability and security.

• disable_command_execute

  • When set to true, rejects Command Execution, Online Terminal and File Manager tasks.

• disable_force_update

  • When set to true, disables forced updates, allowing only manual updates.

• disable_nat

  • When set to true, rejects NAT tasks.

• disable_send_query

  • When set to true, rejects TCPing, ICMP Ping, and HTTP GET tasks.

• gpu

  • When set to true, enables GPU monitoring.
  • Note: Additional dependencies may be required for GPU monitoring. See the GPU Monitoring Guide for details.

• insecure_tls

  • When set to true, disables certificate validation, suitable for scenarios using self-signed certificates.

• ip_report_period

  • Sets the interval (in seconds) for local IP updates. The default is 1800 seconds (30 minutes).
  • The valid minimum value is 30.

• report_delay

  • Sets the interval (in seconds) for system information reporting. The default is 3 seconds (valid range: 1-4 seconds).

• server

  • The domain or IP address of the Dashboard for communication, including the port number.

• skip_connection_count

  • When set to true, disables monitoring of network connection counts, suitable for servers with high connection volumes or limited resources.

• skip_procs_count

  • When set to true, disables monitoring of process counts to lower resource usage.

• temperature

  • When set to true, enables hardware temperature monitoring (only supported for specific hardware; unavailable for some VPS instances).

• tls

  • When set to true, enables SSL/TLS encryption for communication between the Agent and the Dashboard.
  • Enable this option if the Agent uses an SSL/TLS-enabled Nginx reverse proxy.

• hard_drive_partition_allowlist

  • A string array specifying the list of hard drive partitions to monitor.
  • Monitoring will only include the listed partitions.

• nic_allowlist

  • A map[string]bool type whitelist specifying the network interfaces to monitor.
  • The key is the network interface name, and the value is true for monitoring and false for exclusion.
  • If not specified, all available interfaces are monitored by default.

• use_gitee_to_upgrade

  • When set to true, uses the Gitee repository as the automatic update source, better suited for servers in mainland China.

• use_ipv6_country_code

  • When set to true, forces the use of IPv6 addresses for country code queries (default uses IPv4).

• uuid

  • The unique identifier for the current Agent, used by the Dashboard to recognize the data source.
  • To replace an existing Agent in the Dashboard, manually set this parameter.

• dns

  • A string array to set custom DNS server lists.
  • When specified, the Agent will prioritize these DNS servers for domain resolution.

• custom_ip_api

  • A string array specifying custom IP query API endpoints.
  • The Agent will use these APIs to retrieve the server's public IP information.

• self_update_period

  • Set the update interval manually (in minutes).
  • Defaults to a random value between 30 and 90.

Apply Config

After modifying the parameters in the configuration file, you need to restart the Agent service for the changes to take effect. You can use the Agent's built-in service management or restart manually.

Built-in Service Management

You can directly enter the following command to restart the default Agent service:

./agent service restart

For multiple Agent service scenarios, you can specify the corresponding configuration file:

./agent service -c ./config-6sc1f.yml restart

Manual

1. Restart the Service
   Use the following command to restart the default Agent service:

   sudo systemctl restart nezha-agent.service

2. For Multiple Agent Services
   If running multiple Agent services on the same server, first list all Agent services:

   sudo systemctl list-units --type=service | grep nezha-agent

   Then restart each Agent service using the following command:

   sudo systemctl restart <service-name>

   Replace <service-name> with the actual service name, such as nezha-agent@2.service.
