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#

NameTypeRequiredDefaultValid valuesDescription
hoststringTrueIP address or the hostname of the TCP server.
portintegerTrue[0,...]Target upstream port.
timeoutintegerFalse1000[1,...]Timeout for the upstream to send data.
tlsbooleanFalsefalseWhen set to true performs SSL verification.
tls_optionsstringFalseTLS options.
include_req_bodybooleanFalsefalseWhen 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://127.0.0.1:9180/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://127.0.0.1:9180/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
}
}
}'
