Description

Traffic billable items

Restrictions

1. Uploading logs always incur write traffic fees no matter whether you use a private network or public network.
2. Index traffic will be larger than the original log data since the metadata such as \_\_FILENAME\_\_ and \_\_SOURCE__ in CLS constructs indexes and calculates the index traffic.
3. Index traffic will be calculated only once if both the full-text index and key-value index are enabled.

Storage billable items

Restrictions

1. CLS calculates log storage based on the uploaded data volume. For example, suppose the raw log size is 100 GB:

   • If compression is enabled, and the data volume uploaded is 25 GB, the log storage is increased by 25 GB.
   • If compression is not enabled, and the data volume uploaded is 100 GB, the log storage is increased by 100 GB.
   • Similarly, when Log Index is enabled and fields generate index traffic of 50 GB, the index storage is increased by 50 GB.

2. Log storage is billed based on average usage. Storage usage values are collected per minute, and averaged per day. The calculation formula is as follows:

   Daily log storage= “sum of the log storage values per minute for the day” / 1440
   Daily index storage= “sum of the index storage values per minute for the day” / 1440

3. The log data and index data are saved based on your configured storage cycle. Expired data do not incur storage fees and will be deleted on the hour. For example, suppose the storage cycle is set for 3 days and logs are uploaded on June 15 12:15. The logs will be saved between June 15 12:15 and June 18 12:15, and the data will be deleted on June 18 13:00. Do not change the storage cycle frequently, and you can only change it once a day

   • Extending the storage cycle
     When you extend the storage cycle, CLS will save the data for a longer period. For example, if you extend the storage cycle from 7 days to 15 days on June 15 12:30, the data uploaded on June 8 12:00 will be saved to June 23 13:00, instead of being deleted on June 15 13:00.
   • Shortening the storage cycle
     When you shorten the storage cycle, CLS saves data for a reduced period. For example, if you shorten the storage cycle from 15 days to 7 days on June 15, 12:30, the data uploaded between June 1 12:00 and June 8 13:00 will be deleted on June 15 13:00.

Other billable items (on demand)

Restrictions

1. Service request counts the requests from LogListener, API or CLS API calls via SDK. This includes read and write requests such as upload and download, creation and deletion, search and analysis.
2. Service requests will be counted regardless of the request result.

Billing Example

Nginx logs query and analysis

Company A’s website receives 100 million requests per day, and each request produces a 100-byte log on average. This results in 100 million logs with a total size of approximately 9.31 GB per day. Company A decides to upload the Nginx access logs to CLS in the Beijing region, and save them for 15 days for query and statistical analysis.
