The plugin supports the use of batch processors to aggregate and process entries(logs/data) in a batch. This avoids frequent data submissions by the plugin, which by default the batch processor submits data every 5 seconds or when the data in the queue reaches 1000. For information or custom batch processor parameter settings, see Batch-Processor configuration section.

How To Enable

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

curl http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{

        "syslog": {
                "host" : "127.0.0.1",
                "port" : 5044,
                "flush_limit" : 1
            }
    },
    "upstream": {
        "type": "roundrobin",
        "nodes": {
            "127.0.0.1:1980": 1
        }

    "uri": "/hello"
}'

Disable Plugin

Remove the corresponding json configuration in the plugin configuration to disable the sys-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
        }
    }
}'
