Description

Traffic billable items

Traffic billable items	Description	Billing formula
Write traffic	Billed by the data volume received by CLS. If you compress and upload logs, write traffic will be the actual data volume after the compression. LogListener uploads compressed logs by default.	Write traffic fees = unit price per GB * daily accumulated write traffic
Index traffic	Billed by the data volume generated when CLS constructs an index. Index traffic is generated only after the index is enabled, and is dependent on the number of fields configured in the index.	Index traffic fees = unit price per GB * daily accumulated index traffic
Private network read traffic	Billed by the downstream traffic generated when the CLS private domain name is accessed. For example, private network read traffic fees will be incurred when you download CLS logs, consume logs, or ship logs to COS or Ckafka over a private network.	Private network read traffic fees = unit price per GB * daily accumulated private network read traffic
Public network read traffic	Billed by the downstream traffic generated when the CLS public domain name is accessed. For example, public network read traffic fees will be incurred when you download CLS logs, consume logs, or ship logs to COS or Ckafka over a public network.	Public network read traffic fees = unit price per GB * daily accumulated public network read traffic

Restrictions

Uploading logs always incur write traffic fees no matter whether you use a private network or public network.
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.
Index traffic will be calculated only once if both the full-text index and key-value index are enabled.

Storage billable items

Storage billable items	Description	Billing formula
Log storage	Billed by log data storage usage.	Log storage fees = unit price per GB * daily average log storage
Index storage	Billed by index data storage usage.	Index storage fees = unit price per GB * daily average index storage

Restrictions

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.
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
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)

Other billable items	Description	Billing formula
Service request	Billed by the total number of CLS API calls.	Service request fees = unit price per 1,000,000 requests * (daily accumulated number of requests) / 1000000)
Topic partition	Billed by the number of topic partitions used, including the read-write topic partitions and read-only partitions.	Topic partition fees = unit price * daily accumulated number of topic partitions

Restrictions

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.
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.

Billable Item		Description	Quantity	Unit Price (Beijing)	Costs
Traffic fees	Write traffic	LogListener is used to compress and upload logs, resulting in 2.33 GB traffic consumption	2.33 GB	0.032 USD/GB/day	0.075 USD/day
	Index traffic	Full-text index is enabled, generating an index traffic of 11.2 GB (index traffic is larger than the write traffic)	11.2 GB	0.063 USD/GB/day	0.7056 USD/day
	Private network read traffic	There is no download or consumption via a private network. No private network read traffic is generated.	0 GB	0.032 USD/GB/day	0.00 USD/day
	Public network read traffic	There is no download or consumption via a public network. No public network read traffic is generated.	0 GB	0.144 USD/GB/day	0.00 USD/day

Storage fees	Index storage	Indexes of 11.2 GB are generated every day. The average storage capacity after 15 days is 168 GB (11.2 GB * 15 days)	168 GB	0.0025 USD/GB/day	0.42 USD/day
