1-6
Int_16 (priority)
The priority is calculated using the following formula: facility*8+severity, in which facility represents the
logging facility name and can be configured when you set the log host parameters. The facility ranges
from local0 to local7 (16 to 23 in decimal integers) and defaults to local7. The facility is mainly used to
mark different log sources on the log host, query and filter the logs of the corresponding log source.
Severity ranges from 0 to 7. Table 1-1 details the value and meaning associated with each severity.
Note that the priority field takes effect only when the information has been sent to the log host.
timestamp
Timestamp records the time when system information is generated to allow users to check and identify
system events. You can use the info-center timestamp command to configure whether to include a
timestamp in the system information as well as the timestamp format if it is included. The time stamp of
the system information sent from the information center to the log host is with a precision of seconds,
whereas that of the system information sent from the information center to the other destinations is with
a precision of milliseconds.
sysname
Sysname is the system name of the current host. You can use the sysname command to modify the
system name. (Refer to Basic System Configuration Commands in the System Volume for details)
%%
This field is a preamble used to identify a vendor. It is displayed only when the output destination is log
host.
nn
This field is a version identifier of syslog. It is displayed only when the output destination is log host.
module
The module field represents the name of the module that generates system information. You can enter
the info-center source ? command in system view to view the module list.
level (severity)
System information can be divided into eight levels based on its severity, from 0 to 7. Refer to Table 1-1
for definition and description of these severity levels. The levels of system information generated by
modules are predefined by developers, and you cannot change the system information levels. However,
you can configure to output information of the specified level using the info-center source command.
digest
The digest field is a string of up to 32 characters, outlining the system information.
For system information destined to the log host:
z
If the character string ends with (l), the information is log information
z
If the character string ends with (t), the information is trap information
z
If the character string ends with (d), the information is debugging information
For system information destined to other destinations:
z
If the timestamp starts with a %, the information is log information
z
If the timestamp starts with a #, the information is trap information
