Logs Service Description
The Logs service is designed to collect, store, and analyze logs for Selectel products that support log management:
- load balancers;
- Managed Databases;
- ready-to-use 1C Cloud;
- Cloud for Trino;
- Cloud for Redash;
- Cloud for Hive Metastore.
Logs can be used to identify bottlenecks in applications and infrastructure and to quickly detect errors.
Log operations are recorded in audit logs.
How it works
Events that occur with a resource create a record in the log file. Events in a log file can be logically grouped into event streams. Event streams can be grouped together.
An event is a record of application activity, such as an error occurrence. An event is a single record and consists of two parameters:
timestamp– event time;message– event name.
An event stream is a sequence of events from a single source. The event stream identifier is its name. The name is an immutable parameter.
A log group is a set of event streams grouped by retention settings. The name is an immutable parameter of a log group. All log groups created by Selectel products start with the s/ prefix and contain the product abbreviation. For example, in the s/lbaas/my-loadbalancer record, the prefix is s/, and the product abbreviation is lbaas.
