Tengine is a web server originated by Taobao, the largest e-commerce website in Asia. It is based on the Nginx HTTP server and has many advanced features.

This module monitors one or more Tengine instances, depending on your configuration.

Requirements

• tengine with configured ngx_http_reqstat_module.
• collector expects default line format.

Configuration

Edit the go.d/tengine.conf configuration file using edit-config from the Netdata config directory, which is typically at /etc/netdata.

cd /etc/netdata # Replace this path with your Netdata config directory
sudo ./edit-config go.d/tengine.conf

Needs only url to server's /us. Here is an example for 2 servers:

jobs:
  - name: local
    url: http://127.0.0.1/us

  - name: remote
    url: http://203.0.113.10/us

For all available options please see module configuration file.

Troubleshooting

To troubleshoot issues with the tengine collector, run the go.d.plugin with the debug option enabled. The output should give you clues as to why the collector isn't working.

• Navigate to the plugins.d directory, usually at /usr/libexec/netdata/plugins.d/. If that's not the case on your system, open netdata.conf and look for the plugins setting under [directories].

  cd /usr/libexec/netdata/plugins.d/

• Switch to the netdata user.

  sudo -u netdata -s

• Run the go.d.plugin to debug the collector:

  ./go.d.plugin -d -m tengine
