• The first six lines display the number of current active connections of each described type.
• No Memory is the number of times a limit entry could not be created because no memory
was available. If this is a non-zero, positive value, then the system memory should be checked
and, if necessary, increased.
• Logged Records is the number of limit entries logged, both summary and alert log records.
• Log Failures is the number of times log entries have not been logged. A non-zero, positive
value for Log Failures indicates that the size of the kernel log buffer is small. The kernel
log buffer ipl_buff_sz should be set to an appropriate value.
• Limits Added is the number of limit entries that have been added.
• Add Failures is the number of times a limit entry could not be created. This happens
when a state entry is not added. The output of ipfstat -s should be used to further
diagnose the problem.
These statistics are cumulative. They are automatically reset to zero when the ipf module is
unloaded and loaded again.
See Appendix C (page 137) for more information on setting the size of the state table, limit table,
and log buffer.
The following is an example of the output information of the ipfstat -vL option:
