    Simple Log Service:Billable items of pay-by-feature

    Last Updated:Oct 14, 2024

    You are separately charged for the billable items of Simple Log Service. For example, if you collect and store logs, you are charged a write traffic fee and a log storage fee. This topic describes the billable items of pay-by-feature and the fee calculation for each item.

    Precautions

    • You can use the pay-by-feature billing mode when you collect logs and metrics. The pricing of storage and indexes for metrics is different from the pricing of storage and indexes for logs. However, the pricing of other billable items for metrics is the same as the pricing of other billable items of logs. The billable items include data transformation, data shipping, read and write traffic, and the number of requests.

    • You can log on to the Simple Log Service console to view the statistics of the previous day, including the write traffic, read traffic, number of read and write operations, transformation traffic, shipping traffic, and storage usage.

      Simple Log Service updates the statistics on a daily basis.

    • If you use Simple Log Service to collect logs, the logs are automatically compressed. The compression ratio ranges from 10:1 to 5:1.

    Introduction to OCUs

    Observability Capacity Units (OCUs) are a new billing unit that is provided by Alibaba Cloud Cloud Native Observability Platform. The number of OCUs is automatically calculated based on the resource usage per hour.

    Alibaba Cloud plans to gradually implement metered billing on the compute-intensive capabilities of Simple Log Service. The billing unit is OCUs, which measure the actual usage of computing resources. An OCU can be used to offset the fee of 0.5 CPU cores, 2 GB of memory, or 3,000 IOPS. During fee calculation, the system calculates the numbers of OCUs based on the number of consumed cores, size of consumed memory, and IOPS consumption. Then, the system uses the largest number for billing.

    For example, a compute job consumes 1 core, 2 GB of memory, and 3,000 IOPS. In this example, 2 OCUs are consumed. In a billing cycle of 1 hour, approximately 1/3 OCUs are consumed when an ingest processor processes 1 GB of data. Approximately 1/3 OCUs are consumed when the new version of data transformation processes 1 GB of data. Approximately 0.3 OCUs are consumed when rule-based data consumption processes 1 GB of data.

    Description

    Fee calculation

    Free quota

    Storage usage of the hot storage tier

    The fee is calculated based on the storage usage of log data in the hot storage tier. The storage usage is the total size of compressed log data and indexes that are created on raw log data.

    For example, the size of raw log data that is uploaded to Simple Log Service is 1 GB, and indexes are created for two fields. The compression ratio is 5:1 when the raw log data is uploaded, and the size of the indexes is 0.5 GB. In this example, the storage usage of the hot storage tier is calculated by using the following formula: 0.2 GB + 0.5 GB = 0.7 GB.

    • Pay-as-you-go: Daily fee of the storage usage of the hot storage tier = Storage usage per day in GB × Price per GB of log data.

    • Resource plan: Purchased resource plans are used to offset the fees of billable items based on the charge units (CUs) of the billable items.

    Important

    Free quotas are provided only when you do not use resource plans to offset the fees of consumed resources.

    Storage usage of the IA storage tier

    After you enable the intelligent tiered storage feature, logs are moved from the hot storage tier to the Infrequent Access (IA) storage tier (formerly the cold storage tier) after the specified data retention period for the hot storage tier ends. In this case, you are charged based on the storage usage of the IA storage tier. The fee is calculated based on the storage usage of log data in the IA storage tier. The storage usage is the total size of compressed log data and indexes that are created on raw log data.

    For example, the size of raw log data that is uploaded to Simple Log Service is 1 GB, and indexes are created for two fields. The compression ratio is 5:1 when the raw log data is uploaded, and the size of the indexes is 0.5 GB. In this example, the storage usage of the IA storage tier is calculated by using the following formula: 0.2 GB + 0.5 GB = 0.7 GB.

    • Pay-as-you-go: Daily fee of the storage usage of the IA storage tier = Storage usage per day in GB × Price per GB of log data.

    • Resource plan: Purchased resource plans are used to offset the fees of billable items based on the CUs of the billable items.

    Storage usage of the Archive storage tier

    After you enable the intelligent tiered storage feature, logs are moved from the hot storage tier or IA storage tier to the Archive storage tier after the specified data retention period for the hot storage tier or data retention period for the IA storage tier ends. In this case, you are charged based on the storage usage of the Archive storage tier. The fee is calculated based on the storage usage of log data in the Archive storage tier. The storage usage is the total size of compressed log data and indexes that are created on raw log data.

    For example, the size of raw log data that is uploaded to Simple Log Service is 1 GB, and indexes are created for two fields. The compression ratio is 5:1 when the raw log data is uploaded, and the size of the indexes is 0.5 GB. In this example, the storage usage of the Archive storage tier is calculated by using the following formula: 0.2 GB + 0.5 GB = 0.7 GB.

    • Pay-as-you-go: Daily fee of the storage usage of the Archive storage tier = Storage usage per day in GB × Price per GB of log data.

    • Resource plan: Purchased resource plans are used to offset the fees of billable items based on the CUs of the billable items.
