Sep 21, 2015 · If logging does not capture of up severity level 6, this is a finding. Fix Text (F-4517r6_fix) Configure the network device to log all messages except debugging and send all log data to a syslog server. ESP_LOG_BUFFER_HEX_LEVEL (tag, buffer, buff_len, level) ¶ Log a buffer of hex bytes at specified level, separated into 16 bytes each line. Parameters. tag: description tag . buffer: Pointer to the buffer array . buff_len: length of buffer in bytes . level: level of the log . ESP_LOG_BUFFER_CHAR_LEVEL (tag, buffer, buff_len, level) ¶ Log a System Message Logging – SYSLOG Modern network devices have advanced from simple transmitting of messages (email.documents, multimedia etc), network devices like Cisco routers and switches provide the features for network administrators to reading system messages from their internal buffer about network situation at a particular time. The way to do this is by using the Syslog server. Cisco ASA1(config)# logging buffered warnings. This will log all syslog messages with level “warnings” or lower to the internal buffer. We can also configure the size of the internal buffer: ASA1(config)# logging buffer-size 8192. By default it’s only 4KB, I changed it to 8KB with the logging buffer-size command. Let’s see if we can find some A buffer of this size can hold approximately 50 log messages before overwriting occurs. Fifty messages, although better than no logging, is relatively small, and most engineers will want increase their buffer size to store more messages. To check the size of your router’s logging buffer, use the show buffer command:
Buffered logging The buffer will not be flushed until it is full. There is a potential loss of data should a system crash occur before the buffer is flushed to disk. Unbuffered logging The buffer is flushed as soon as any transaction is complete (i.e. a commit or rollback record is written to the log buffer). This mode guarantees that the log

What are debug logs and how do I use them? - Helpshift
Terminal logging:It is similar to console logging, but it displays log messages to the router's VTY lines instead. This is not enabled by default This is not enabled by default Buffered logging: This type of logging uses router's RAM for storing log messages. buffer has a fixed size to ensure that the log will not deplete valuable system memory. Logging can be optimized by enabling the buffer for log messages and the cache of descriptors of frequently used log files whose names contain variables. To enable buffering use the buffer parameter of the access_log directive to specify the size of the buffer.
