error-log-logger

Description#

The error-log-logger Plugin is used to push APISIX's error logs (error.log) to TCP, Apache SkyWalking, or ClickHouse servers. You can also set the error log level to send the logs to 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.

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#

To enable the Plugin, you can add it in your configuration file (conf/config.yaml):

conf/config.yaml
plugins:
- request-id
- hmac-auth
- api-breaker
- error-log-logger

Once you have enabled the Plugin, you can configure it through the Plugin metadata.

Configuring TCP server address#

You can set the TCP server address by configuring the Plugin metadata as shown below:

curl http://127.0.0.1:9180/apisix/admin/plugin_metadata/error-log-logger -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
"tcp": {
"host": "127.0.0.1",
"port": 1999
},
"inactive_timeout": 1
}'

Configuring SkyWalking OAP server address#

You can configure the SkyWalking OAP server address as shown below:

curl http://127.0.0.1:9180/apisix/admin/plugin_metadata/error-log-logger -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
"skywalking": {
"endpoint_addr":"http://127.0.0.1:12800/v3/logs"
},
"inactive_timeout": 1
}'

Configuring ClickHouse server details#

The Plugin sends the error log as a string to the data field of a table in your ClickHouse server.

You can configure it as shown below:

curl http://127.0.0.1:9180/apisix/admin/plugin_metadata/error-log-logger -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
"clickhouse": {
"user": "default",
"password": "a",
"database": "error_log",
"logtable": "t",
"endpoint_addr": "http://127.0.0.1:8123"
}
}'
