tcp-logger

Description

The tcp-logger Plugin can be used to push log data requests to TCP servers.

This provides the ability to send log data requests as JSON objects to monitoring tools and other TCP servers.

This plugin also allows to push logs as a batch to your external TCP server. It might take some time to receive the log data. It will be automatically sent after the timer function in the batch processor expires.

Attributes

Name	Type	Required	Default	Valid values	Description
host	string	True			IP address or the hostname of the TCP server.
port	integer	True		[0,...]	Target upstream port.
timeout	integer	False	1000	[1,...]	Timeout for the upstream to send data.
tls	boolean	False	false		When set to true performs SSL verification.
tls_options	string	False			TLS options.
include_req_body	boolean	False	false		When set to true includes the request body in the log.

This Plugin supports using batch processors to aggregate and process entries (logs/data) in a batch. This avoids the need for frequently submitting the data. The batch processor submits data every 5 seconds or when the data in the queue reaches 1000. See Batch Processor for more information or setting your custom configuration.

Enabling the Plugin

The example below shows how you can enable the tcp-logger Plugin on a specific Route:

curl http://127.0.0.1:9080/apisix/admin/routes/5 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
      "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"
}'

Example usage

Now, if you make a request to APISIX, it will be logged in your TCP server:

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

Disable Plugin

To disable the tcp-logger Plugin, you can delete the corresponding JSON configuration from the Plugin configuration. APISIX will automatically reload and you do not have to restart for this to take effect.

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
        }
    }
}'
