Name

tcp-logger is a plugin which push Log data requests to TCP servers.

This will provide the ability to send Log data requests as JSON objects to Monitoring tools and other TCP servers.

This plugin provides the ability to push Log data as a batch to your external TCP servers. In case if you did not receive the log data don't worry give it some time it will automatically send the logs after the timer function expires in our Batch Processor.

For more info on Batch-Processor in Apache APISIX please refer. Batch-Processor

The following is an example on how to enable the tcp-logger for a specific route.

{
      "plugins": {
            "tcp-logger": {
                 "host": "127.0.0.1",
                 "port": 5044,
                 "tls": false,
                 "batch_max_size": 1,
                 "name": "tcp logger"
            }
       },
      "upstream": {
           "type": "roundrobin",
           "nodes": {
               "127.0.0.1:1980": 1
           }
      },
      "uri": "/hello"
}'

• success:

$ curl -i http://127.0.0.1:9080/hello

hello, world

Disable Plugin

Remove the corresponding json configuration in the plugin configuration to disable the tcp-logger. APISIX plugins are hot-reloaded, therefore no need to restart APISIX.

$ curl http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
    "methods": ["GET"],
    "uri": "/hello",
    "plugins": {},
    "upstream": {
        "type": "roundrobin",
        "nodes": {
            "127.0.0.1:1980": 1
        }
    }
}'
