syslog

Description#

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

Logs can be set as JSON objects.

Attributes#

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://127.0.0.1:9180/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://127.0.0.1:9180/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
}
}
}'
