Log Service supports the pay-as-you-go billing method. In this case, you are charged based on the amount of consumed resources. The default billing method is pay-as-you-go after you activate Log Service. This topic describes the details of the pay-as-you-go billing method.

For more information about the billable items and billing method of Log Service, see Billing overview. For more information about the pricing of Log Service, see Log Service pricing.

Billing period

Fees are deducted from the balance of your Alibaba Cloud account on a daily basis. A bill is generated every day based on the amount of resources that are consumed on the previous day.

Free quotas

Log Service provides free quotas for some billable items. The following table shows the item details.
Note Log Service offers monthly free quotas. These free quotas are cleared at the end of each month. If the amount of resources consumed in a month is within the free quotas, you are not charged. Otherwise, you are charged for the excess amount.
Billable item Monthly free quota
Storage space occupied by log data 500 MB
Read and write traffic 500 MB
Indexes created or recreated for log data 500 MB
Active shards 31 (one shard per day)
Note If you set Shards to 2 when you create a Logstore, this value indicates that you rent two shards each day. The monthly usage is 60 shards in 30 days. You are not charged during the first 15 days. However, you are charged from the 16th day. This billing method is applied again in the next month.

Billing examples

  • Example 1: free quotas
    Assume that you have three servers. Each server generates 5 MB of log data every day. In this case, you can use Log Service to perform the following operations:
    1. Query logs in real time and create a dashboard. This allows you to visualize data query and analysis results.
    2. Use a Java program to subscribe to log processing events. This allows you to track log processing results in real time.
    Billable item Description
    Shard Only one Logstore and one shard are created for 31 days in a month. This billable item is within the free quota.
    Note By default, two shards are created when you create a Logstore. To make sure that the number of active shards is within the free quota, you can modify the Shards parameter to 1.
    Read and write traffic A total of 15 MB of raw logs are generated every day. Assume that the compression ratio is 20%. The daily read and write traffic is 6 MB (15 MB × 20% × 2 = 6 MB). The monthly cumulative read and write traffic is 186 MB (6 MB/day × 31 days = 186 MB). This billable item is within the free quota.
    Index traffic (logs) The index traffic is 465 MB (15 MB/day × 31 days = 465 MB). This billable item is within the free quota.
    Read and write operations The number of monthly read and write operations is less than 1 million. This billable item is within the free quota.
  • Example 2: real-time computing and offline computing

    A website receives 100 million API requests per day. Each request generates a 200-byte log. The size of logs that are generated per day is 20 GB. The peak traffic is 1.16 MB/s, which is five times the average traffic. The lifecycle of these logs is two days. These logs are read once a day for real-time computing, and shipped to OSS for offline computing.

    The fee incurred for one day is USD 3.3375 (USD 0.01 + USD 0.09 + USD 0.09 + USD 0.0115 + USD 0.136 + USD 3 = USD 3.3375). The following table shows the billing details.
    Billable item Description
    Shard Reserve a shard and you are charged USD 0.01 for the shard.
    Read and write traffic A total of 20 GB of raw logs are written every day. Assume that the compression ratio is 10%. The daily write traffic is 2 GB and the fee is USD 0.09 (2 GB × USD 0.045/GB = USD 0.09).
    The same amount of log data is pulled for real-time computing. The fee is USD 0.09.
    The storage fee is USD 0.0115 (2 GB × 2 days × USD 0.002875/GB/day = USD 0.0115).
    The fee for shipping logs to OSS in the CSV format is USD 0.136 (20 GB × USD 0.0068/GB = USD 0.136).
    API requests The fee incurred by 100 million requests is USD 3 (USD 0.00000003 /request × 100,000,000 requests = USD 3).
  • Example 3: log indexes and online queries

    A cloud service receives 1 million API requests per day. Each request generates a 200-byte log. The size of logs generated per day is 200 MB. These logs are stored in Log Service for 30 days so that you can query data of the last 30 days.

    The fee incurred for one day is USD 0.0690625 (USD 0.0175 + USD 0.0215625 + USD 0.03 = USD 0.0690625). The following table shows the billing details.
    Billable item Description
    Index traffic (logs) If you create indexes for all fields, the index traffic fee is USD 0.0175 (0.2 GB × USD 0.0875/GB = USD 0.0175).
    Storage space (logs) 200 MB +50 MB (index traffic) = 250 MB. The maximum storage space is 7.5 GB (0.25 GB × 30 days = 7.5 GB). The maximum daily storage fee is USD 0.0215625 (7.5 GB × USD 0.002875/GB/day = USD 0.0215625).

    Index traffic is compressed from raw logs. The compression ratio is 25%.

    API requests The fee incurred by 1 million requests is USD 0.03 (USD 0.00000003 /request × 1,000,000 requests = USD 0.03).
  • Example 4: time series data storage

    A cloud service writes 400 MB of time series data to Log Service per day. The data is stored for 15 days.

    The fee incurred for one day is USD 0.014124 (USD 0.010884 + USD 0.00324 = USD 0.014124). The following table shows the billing details.
    Billable item Description
    Index traffic (time series) If you create indexes for all fields, the index traffic fee is USD 0.010884 (0.4 GB × USD 0.02721/GB = USD 0.010884).
    Storage space (time series) 400 MB + 50 MB (index traffic) = 450 MB. The maximum storage space is 6.75 GB (0.45 GB × 15 days = 6.75 GB). The maximum daily storage fee is USD 0.00324 (6.75 GB × USD 0.00048/GB/day = USD 0.00324).

    Index traffic is compressed from raw logs. The compression ratio is 12.5%.
