Term | Description |
project | A project in Simple Log Service is used to isolate the resources of different users and control access to specific resources. For more information, see Project. |
Logstore | A Logstore in Simple Log Service is used to collect, store, and query logs. For more information, see Logstore. |
Metricstore | A Metricstore in Simple Log Service is used to collect, store, and query metrics. For more information, see Metricstore. |
log | Logs are records of changes that occur in a system during the runtime of the system. The records contain information about the operations that are performed on specified objects and the results of the operations. The records are ordered by time. For more information, see Log. |
log group | A log group is a collection of logs. A log group is the basic unit that is used to write and read logs. Logs in a log group contain the same metadata, such as the IP address and log source. For more information, see Log group. |
metric | Metrics are stored as time series. For more information, see Metric. |
trace | Traces indicate the execution process of an event or a procedure in a distributed system. For more information, see Trace. |
shard | A shard is used to control the read and write capacities of a Logstore. In Simple Log Service, data is stored in shards. Each shard has an MD5 hash range, and each range is a left-closed, right-open interval. The ranges do not overlap with each other. Each range must be within the entire MD5 hash range [00000000000000000000000000000000,ffffffffffffffffffffffffffffffff). For more information, see Shard. |
topic | A topic is a basic management unit in Simple Log Service. You can specify topics when you collect logs. This way, Simple Log Service can classify logs by topic. For more information, see Topic. |
endpoint | An endpoint of Simple Log Service is a URL that is used to access a project and the data of the project. To access the projects in different regions, you must use different endpoints. To access the projects in the same region over an internal network or the Internet, you must also use different endpoints. For more information, see Endpoints. |
AccessKey pair | An AccessKey pair is an identity credential that consists of an AccessKey ID and an AccessKey secret. The AccessKey ID and AccessKey secret are used for symmetric encryption and identity authentication. The AccessKey ID is used to identify a user. The AccessKey secret is used to encrypt and verify a signature string. The AccessKey secret must be kept confidential. For more information, see AccessKey pair. |
region | A region is a physical location where a data center of Simple Log Service is deployed. You can specify a region when you create a project. After the project is created, you cannot change the region. For more information, see Supported regions. |
