Pydio LOG

Pydio relies on zap logging framework.

We mainly use 2 loggers that are defined in this package and used throughout the backend:

• A syslog logger: it should be used to log technical information.
• An audit logger: it only logs some very precise information at strategic places and is used to monitor the Application from a business point of view. Audit logs are among others used for GRDP compliance.

WARNING: you should not modify nor remove any of the audit log.

Guidelines

• When enriching the log with zap fields, always use constants from common/zapfields.go as keys, otherwise the logs won't be usable for analysis
• Pydio provides some shortcuts to easily generate zap fields for commons pydio objects. Typically when loging info about a tree.Node, one should write: ...Debug("A message", node.Zap())
• Depending on the level of details required, one can either use Zap() that serializes all accessible information or ZapPath(), ZapUuid() or ZapId() (depending on the relevant info) that simply calls zap.String() with relevant pydio zap id (as seen in common/zapfields.go) and corresponding value.

Conventions

• it is idiomatic in Go to write error message that start with a lower case letter and do not end with a punctuation mark.

Overview

Package log define and configure the Pydio loggers based on zap.

We mainly use 2 loggers that are defined in this package and used throughout the backend: - A syslog logger: it should be used to log technical information. - An audit logger: it only logs some very precise information at strategic places and is used to monitor the Application from a business point of view. Audit logs are among others used for GRDP compliance.

WARNING: you should not modify nor remove any of the audit log.
