Temporary Access Statistics Logs¶
Context¶
You can check access logs in either of the following ways:
Enable and check access logs via an independent API. Configure the API parameters to record the access log time and size. The access log content is returned through a REST API.
Print access logs. Your access logs are printed as files in backend logs. This section describes how to temporarily access logs in this mode.
When the access log function is enabled or disabled, the parameters involved in the command are as follows:
Parameter | Type | Description |
---|---|---|
duration_limit | String | Duration recorded in an access log. Value range: 10 to 120 Unit: s Default value: 30 |
capacity_limit | String | Size of an access log. After access logging is enabled, the size of recorded requests is checked. If the size exceeds the value of this parameter, the access logging stops. Value range: 1 to 5 Unit: MB Default value: 1 |
Note
Access logging stops if either duration_limit or capacity_limit reaches the threshold.
Procedure¶
Log in to the CSS management console.
Choose Clusters in the navigation pane. On the Clusters page, locate the target cluster and click Access Kibana in the Operation column.
In the navigation pane on the left, choose Dev Tools and run commands to enable or disable access logs.
