If the number of your active shards exceeds the free quota, rental fees are incurred.
Log Service allows you to read data from and write data to active shards. You are charged for using active shards based on the number of active shards and rental periods. If the number of your active shards exceeds the free quota, rental fees are incurred.
The following table describes the billing examples of active shards based on billing methods.

Each shard supports data writing of 5 MB/s and data reading of 10 MB/s. If the total data traffic of used shards is less than the maximum read and write capabilities of a shard, we recommend that you merge shards. The merged shard is inactive and no rental fees are incurred. For more information, see Merge shards.
