 Logs are classified into the following levels in descending order by importance: error , warning ,
info , and debug . eSpace 7910/eSpace 7950 records logs of the preset level and the level(s) above the
preset one. For example, if you have set the log level to warning , eSpace 7910/eSpace 7950 records
logs at levels of error , warning and info .
 It is recommended that you set the log level to debug , so that eSpace 7910/eSpace 7950 records logs
at all four levels.
Log Description
Logs provide internal system information when eSpace 7910/eSpace 7950 malfunctions,
which is an important means of locating faults.
The system logs reported by eSpace 7910/eSpace 7950 provide key information about eSpace
7910/eSpace 7950 records. eSpace 7910/eSpace 7950 logs have four levels: error, warning,
info, and debug. These four levels are defined as follows:

error: Unexpected data or events that have a large sphere of influence or that cause
partial function failure (and such failures affect subsequent service status) are logged at
error level.

warning: Events for unexpected system status that does not affect system running are
logged at warning level.

info: The system status information and process directory tracing information generated
in functional system running are logged at info level.

debug: The information about system debugging performed by R&D engineers is logged
at debug level.
Figure 1-5 and Table 1-4 use some logs as an example to describe the logs.

No. Description
Log type, including:
 Operation: operation logs, which contain the operations performed by system
users (including system administrators, operation and maintenance engineers,
and system monitoring engineers) or those initiated by the scheduled system
tasks.
 System: system logs, which contain key activities generated during the system
running.
 Security: security logs, which contain activities of system users (including
system administrators, operation and maintenance engineers, and system
monitoring engineers). These activities include login, logout, and authentication.
 Debug: debug logs, which contain the system debugging operations performed
by R&D engineers. Such logs facilitate code correction for R&D engineers.
