This document introduces the features and collection methods related to FileNAS logs.

Feature overview

File storage NAS (FileNAS) is a file storage service designed for Volcano Engine elastic computing, container services, and AI intelligent applications. It provides business applications with a high-performance, shared-access, always-online, elastic scaling, cross-region access, and cost-effective cloud storage service.

Log analysis can be enabled for FileNAS data movement tasks. Once enabled, real-time query and analysis of the data movement records for the data movement policy will be available.

The relevant configuration is as follows:

Configuration	Description
Log type	FileNAS data movement logs.
Log storage location	When creating a data movement policy and enabling log analysis, TLS will automatically create the corresponding project and log topic. For details on managing log resources, see Manage FileNAS log resources. Project: filenas-service-project-1 Log topic: Data movement policy ID
Log storage period	The default is 3650 days.
Log shard	One shard is preset. The auto split feature for log topic shards is enabled by default.
Index settings	Index is configured automatically.
Log fields	For a detailed list of log fields, see FileNAS log fields.
