Configuring Log Aggregation
 
Filebeat
You can configure log aggregation such that the logs from different components can be stored at a single location in a common format. You can select any of the following destinations to store the aggregated data:
*API Data Store
*Elasticsearch, in case you have an external Elasticsearch configured with API Gateway
Log aggregation collects log from the different components and stores them either in API Data Store or external Elasticsearch based on the log aggregation configuration settings. If the API Data Store is configured as the destination the aggregated logs are displayed in the API Gateway dashboard under the Analytics > Application logs tab. You can filter the logs as required and search for a particular log in the dashboard.
Note:
If you configure to send the logs to the same API data store, which stores the API Gateway's core data (APIs & configurations), then it is very important to setup the data housekeeping in place since the log data grows over time in volume and will start to impact API Gateway's performance. For more information on log housekeeping practices, see Logs Housekeeping. Alternatively (also a better approach for production environments), logs can be sent to an External Elasticsearch.
Prerequisite:You must have the Manage general administration configurations functional privilege to:
*Enable the log aggregation and
*Configure the destination for log aggregation
*To configure log aggregation
1. Expand the menu options icon in the title bar, and select Administration.
2. Select General > Application logs.
3. In the Log aggregation section, click the toggle button to change the status to and enable the log aggregation.
4. Select one of the following destination:
*API Gateway Data Store: Select this to set API Data Store as destination to store the aggregated logs and you can view them in the API Gateway dashboard
*External Elasticsearch. Select this to set the external Elasticsearch as destination to store the aggregated log. This approach helps to separate the Elasticsearch that stores the API Gateway core data from the aggregated log . But, if you use the external Elasticsearch, you must create your own dashboard to view the logs.
Note:
Make sure you have configured an external Elasticsearch with API Gateway.
Provide the following information:
Field Name
Description
Protocol
The type of protocol (HTTP, HTTPS) to use for the host and port combination.
Hostname
Specifies the host name or IP address of the machine on which Elasticsearch resides.
Port
Specifies the port where Elasticsearch server runs.
Indexname
Specifies the index of the collected logs.
Username
Specifies the Elasticsearch user ID for authenticating Elasticsearch when API Gateway communicates with it.
Password
Specifies the password of the Elasticsearch instance to be used for establishing communication between API Gateway and Elasticsearch.
5. Click Save.
The selected destination is now configured for log aggregation.
