syslog

Description#

The syslog Plugin is used to push logs to a Syslog server.

Logs can be set as JSON objects.

port	integer	True			Target port of the Syslog server.
name	string	False	"sys logger"		Identifier for the server.
timeout	integer	False	3000	[1, ...]	Timeout in ms for the upstream to send data.
tls	boolean	False	false		When set to `true` performs TLS verification.
flush_limit	integer	False	4096	[1, ...]	Maximum size of the buffer (KB) and the current message before it is flushed and written to the server.
drop_limit	integer	False	1048576		Maximum size of the buffer (KB) and the current message before the current message is dropped because of the size limit.
sock_type	string	False	"tcp"	["tcp", "udp]	Transport layer protocol to use.
max_retry_times	integer	False		[1, ...]	Deprecated. Use `max_retry_count` instead. Maximum number of retries if a connection to a log server fails.
retry_interval	integer	False		[0, ...]	Deprecated. Use `retry_delay` instead. Time in ms before retrying the connection to the log server.
pool_size	integer	False	5	[5, ...]	Keep-alive pool size used by `sock:keepalive`.
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 Plugin for a specific Route:

curl http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
    "plugins": {
        "syslog": {
                "host" : "127.0.0.1",
                "port" : 5044,
                "flush_limit" : 1
            }
    },
    "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 Syslog server:

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

Disable Plugin#

To disable the syslog 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
        }
    }
}'
