Simple Log Service:Manage a logstore

Introduction to logstores

Limits

Create a logstore

1. Log on to the Simple Log Service console.

2. In the Projects section, click the project that you want to manage.

   

3. On the Log Storage > logstores tab, click the + icon.

   

4. In the Create logstore panel, configure the following parameters and click OK.

   Parameter	Description
   Logstore Type	You can upgrade a Query logstore to a Standard logstore. You cannot downgrade a Standard logstore to a Query logstore. Important After you upgrade a Query logstore to a Standard logstore, Enable Analytics is automatically turned on for the existing fields. You can analyze only new logs that are written to Simple Log Service after the upgrade. Fees are not generated on the index traffic of historical data. For the index traffic of the new logs, fees are generated, and the involved billable item is the index traffic of log data. For more information, see Billable items of pay-by-feature.
   Billing Mode	The billing mode of the logstore. Valid values: Pay-by-ingested-data and Pay-by-feature. For more information, see Billable items.
   Logstore Name	The name of the logstore. The name must be unique in the project to which the logstore belongs. After the logstore is created, you cannot change the name of the logstore.
   WebTracking	If you turn on WebTracking, you can collect data from HTML, HTML5, iOS, and Android platforms to Simple Log Service by using the web tracking feature. For more information, see Use the web tracking feature to collect logs.
   Data Retention Period	The retention period of logs in the logstore. If you set the Data Retention Period parameter to Specified Days, you can specify the number of days for which you want to store logs based on your business requirements. Valid values: 1 to 3650. Unit: days. After the retention period ends, logs are automatically deleted. If you set this parameter to 3650, data is permanently stored. If you change the retention period, Simple Log Service deletes all expired data within 1 hour. The data volume that is displayed for Usage Details on the homepage of the Simple Log Service console is updated the next day. For example, if you change the retention period from 5 days to 1 day, Simple Log Service deletes the logs of the previous four days within 1 hour. If you set the Data Retention Period parameter to Permanent Storage, Simple Log Service permanently stores the collected logs in the logstore. Note If you query the retention period by calling an API operation and the returned result is 3650, logs are permanently stored.
   Intelligent Tiered Storage	For more information about how to enable intelligent tiered storage, see Configure intelligent tiered storage. For more information about the fees generated for data storage in the hot storage tier, Infrequent Access (IA) storage tier, and Archive storage tier, see Billable items.
   Automatic Sharding	If you turn on Automatic Sharding, Simple Log Service increases the number of shards when the existing shards cannot accommodate the data that is written. For more information, see Manage shards.
   Maximum Shards	If you turn on Automatic Sharding, you must configure this parameter to specify the maximum number of readwrite shards that can be created. Maximum value: 256.
   Log Public IP	If you turn on Log Public IP, Simple Log Service adds the following information to the Tag field of the collected logs: __client_ip__: the public IP address of the log source. __receive_time__: the time at which Simple Log Service receives the log. The value is a UNIX timestamp representing the number of seconds that have elapsed since January 1, 1970, 00:00:00 UTC.

Modify the configurations of a logstore

1. On the Log Storage > Logstores tab, move the pointer over the logstore you want and choose > Modify.

   

2. On the Logstore Attributes page, click Modify. After you modify the parameters, click Save. For more information about the parameters, see Create a logstore.

   

Delete a logstore

1. Before deletion

   1. Before you can delete a logstore, you must delete all Logtail configurations that are associated with the logstore. For more information, see Delete Logtail configurations.

   2. If the log shipping feature is enabled for the logstore, we recommend that you stop writing data to the logstore and make sure that all data in the logstore is shipped before you delete the logstore.

2. Deletion

   1. On the Log Storage > Logstores tab, move the pointer over the logstore that you want to delete and choose > Delete.

      Warning

      After you delete a logstore, all logs in the logstore are deleted and cannot be restored. Proceed with caution.

   2. In the Warning dialog box, enter the logstore name and click Confirm Deletion.

3. After deletion

   1. After you delete all logstores, you are still charged for data storage on the day that you delete the logstores. You are no longer charged for data storage starting the following day. Starting the third day after you delete all logstores, you no longer receive a Simple Log Service bill.

Appendix: logstore comparison by type

If you set the Billing Mode parameter to Pay-by-feature, you can set the logstore Type parameter to Standard or Query. The following table describes the differences between the two types of logstores.
