Buffered and Unbuffered Logging
361
Log level
Message category
Description
2
Warning
These messages are warnings only and do not indicate any failure in the normal operation of the server.
3
Failure; the default selection
for system and error logs
These messages indicate errors and failures that prevent the server from operating normally, including failures to perform a certificate service
operation (
User authentication failed
or
Certificate revoked
) and unexpected situations that can cause irrevocable errors (
The server cannot send
back the request it processed for a client through the same channel the request came from the client
).
4
Misconfiguration
These messages indicate that a misconfiguration in the server is causing an error.
5
Catastrophic failure
These messages indicate that, because of an error, the service cannot continue running.
6
Security-related events
These messages identify occurrences that affect the security of the server. For example,
Privileged access attempted by user with
revoked or unlisted certificate
.
Table 15.2. Log Levels and Corresponding Log Messages
There are an additional four log levels available for TPS and RA subsystem logs:

Description
7
PDU related events
(debugging)
These messages contain debugging information for PDU events. This level is not recommended for regular use because it generates too much
information for normal use.
8
PDU related events
These messages relate transactions and rules processed on a PDU, such as creating MAC tokens.
9
PDU related events
This log levels gives verbose log messages for events processed on a PDU, such as creating MAC tokens.
10
All logging levels
This log level enabled all logging levels for the TPS logs.
Table 15.3. TPS and RA Log Levels and Log Entries
Log levels can be used to filter log entries based on the severity of an event. By default, log level 3
(Failure) is set for all services.
The log level is successive; specifying a value of 3 causes levels 4, 5, and 6 to be logged. Log data
can be extensive, especially at lower (more verbose) logging levels. Make sure that the host machine
has sufficient disk space for all the log files. It is also important to define the logging level, log rotation,
and server-backup policies appropriately so that all the log files are backed up and the host system
does not get overloaded; otherwise, information can be lost.
15.1.3. Buffered and Unbuffered Logging
The Certificate System supports buffered logging for all types of logs. The server can be configured for
either buffered or unbuffered logging.
If buffered logging is configured, the server creates buffers for the corresponding logs and holds the
messages in the buffers for as long as possible. The server flushes out the messages to the log files
only when one of the following conditions occurs:
• The buffer gets full. The buffer is full when the buffer size is equal to or greater than the value
specified by the
bufferSize
configuration parameter. The default value for this parameter is 512
KB.
• The flush interval for the buffer is reached. The flush interval is reached when the time interval
since the last buffer flush is equal to or greater than the value specified by the
flushInterval
configuration parameter. The default value for this parameter is 5 seconds.
• When current logs are read from Console. The server retrieves the latest log when it is queried for
current logs.
