Standardized Logs

Standardized log messages can be streamed to GigaVUE‑FM. The log messages follow the industry standard described in RFC5424. The format includes structured data, timestamp, version, and message ID. The timestamp includes milliseconds for increased accuracy.

In GigaVUE‑FM, the log information is displayed in a table with configurable, sortable columns and extensive filter options.

Refer to View Device Logs for information about viewing and filtering logs in GigaVUE‑FM.

Refer to the GigaVUE‑OS-CLI User’s Guide for information about the standardized log message format in the CLI view.

Device Log Categories

Device Logging Levels

Table 3: Logging Levels shows the standard logging levels that are used to rank logged events by degree of severity. When configuring the device/cluster logs to stream, the highest severity level will capture fewer logs than the lowest severity. For example, if the lowest level (info or debug) is selected in your configuration, all levels of logs, from the selected level up to the highest level, will be streamed. If the highest level (emergency) is selected, only emergency logs will be streamed.

Note:   If you change the logging severity of the nodes through GigaVUE-OS CLI, then the same will not be reflected in GigaVUE-FM. Therefore, it is recommended to change the logging severity of the nodes through GigaVUE-FM.

Table 3: Logging Levels

Log-Level

Description

emergency

Emergency – the system is unusable. The severity level with the least logging – only emergency level events/commands are logged.

alert

Action must be taken immediately.

critical

Critical conditions.

error

Error conditions.

warning

Warning conditions.

notice

Normal but significant condition.

info

Informational messages.

debug

Debug-level messages. Authorized for factory use only.

Device Logging Processes

Logs that are specific to a process are logged with the process ID. Table 4: Logging Processes provides a list of logging processes and their descriptions.
