This document contains information about the Apache APISIX google-cloud-logging Plugin.

Description

The google-cloud-logging Plugin is used to send APISIX access logs to Google Cloud Logging Service.

This plugin also allows to push logs as a batch to your Google Cloud Logging Service. 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

Name Required Default Description
auth_config True Either auth_config or auth_file must be provided.
auth_config.private_key True Private key of the Google Cloud service account.
auth_config.project_id True Project ID in the Google Cloud service account.
auth_config.token_uri True https://oauth2.googleapis.com/token Token URI of the Google Cloud service account.
auth_config.entries_uri False https://logging.googleapis.com/v2/entries:write Google Cloud Logging Service API.
auth_config.scopes False ["https://www.googleapis.com/auth/logging.read", "https://www.googleapis.com/auth/logging.write", "https://www.googleapis.com/auth/logging.admin", "https://www.googleapis.com/auth/cloud-platform"] Access scopes of the Google Cloud service account. See OAuth 2.0 Scopes for Google APIs.
auth_file True Path to the Google Cloud service account authentication JSON file. Either auth_config or auth_file must be provided.
ssl_verify False true When set to true, enables SSL verification as mentioned in OpenResty docs.
resource False {"type": "global"} Google monitor resource. See MonitoredResource for more details.
log_id False apisix.apache.org%2Flogs Google Cloud logging ID. See LogEntry for details.

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

Full configuration

The example below shows a complete configuration of the Plugin on a specific Route:

curl http://127.0.0.1:9180/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
    "plugins": {
        "google-cloud-logging": {
            "auth_config":{
                "project_id":"apisix",
                "private_key":"-----BEGIN RSA PRIVATE KEY-----your private key-----END RSA PRIVATE KEY-----",
                "token_uri":"https://oauth2.googleapis.com/token",
                "scopes":[
                    "https://www.googleapis.com/auth/logging.admin"
                ],
                "entries_uri":"https://logging.googleapis.com/v2/entries:write"
            },
            "resource":{
                "type":"global"
            },
            "log_id":"apisix.apache.org%2Flogs",
            "inactive_timeout":10,
            "max_retry_count":0,
            "buffer_duration":60,
            "retry_delay":1,
            "batch_max_size":1
        }
    },
    "upstream": {
        "type": "roundrobin",
        "nodes": {
            "127.0.0.1:1980": 1
        }
    },
    "uri": "/hello"
}'

Minimal configuration

The example below shows a bare minimum configuration of the Plugin on a Route:

curl http://127.0.0.1:9180/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
    "plugins": {
        "google-cloud-logging": {
            "auth_config":{
                "project_id":"apisix",
                "private_key":"-----BEGIN RSA PRIVATE KEY-----your private key-----END RSA PRIVATE KEY-----"
            }
        }
    },
    "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 Google Cloud Logging Service.

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

You can then login and view the logs in Google Cloud Logging Service.

Disable Plugin

To disable the google-cloud-logging 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 '
{
    "uri": "/hello",
    "plugins": {},
    "upstream": {
        "type": "roundrobin",
        "nodes": {
            "127.0.0.1:1980": 1
        }
    }
}'
