Usage Guidelines
The logging correlator buffer-size command configures the size of the correlation buffer. This buffer holds
all the correlation records as well as the associated correlated messages. When the size of this buffer is
exceeded, older correlations in the buffer are replaced with the newer incoming correlations. The criteria that
are used to recycle these buffers are:
•
First, remove the oldest nonstateful correlation records from the buffer.
•
Then, if there are no more nonstateful correlations present; remove the oldest stateful correlation records.
Use the show logging correlator info, on page 50 command to confirm the size of the buffer and the percentage
of buffer space that is currently used. The show logging events buffer, on page 57 all-in-buffer command
can be used to show the details of the buffer contents.
