Example—`kstat` Statistics for IPQoS

Here is an example of possible results from running kstat to obtain statistics about the flowacct module.

# kstat -m flowacct
module: flowacct                        instance: 3     
name:   Flowacct statistics             class:    flacct 
        bytes_in_tbl                    84
        crtime                          345728.504106363
        epackets                        0
        flows_in_tbl                    1
        nbytes                          84
        npackets                        1
        snaptime                        345774.031843301
        usedmem                         256

Entry	Description
`class: flacct`	Gives the name of the class to which the traffic flows belong, in this instance `flacct`.
`bytes_in_tbl`	Total number of bytes in the flow table, that is, the sum in bytes of all the flow records that currently reside in the flow table. The total number of bytes for this flow table is 84. If no flows are in the table, the value for `bytes_in_tbl` is 0.
`crtime`	The last time this `kstat` was created.
`epackets`	Number of packets that resulted in an error during processing, in this instance 0.
`flows_in_tbl`	Number of flow records in the flow table, which in this instance is 1. When no records are in the table, the value for `flows_in_tbl` is 0.
`nbytes`	Total number of bytes that are seen by this `flowacct` action instance, which is 84 in the example. The value includes bytes that are currently in the flow table and bytes that have timed out—are no longer in the flow table.
`npackets`	Total number of packets that are seen by this `flowacct` action instance, which is 1 in the example. `npackets` includes packets that are currently in the flow table and those that have timed out—are no longer in the flow table.
`usedmem`	Memory in bytes in use by the flow table that is maintained by this `flowacct` instance. The `usedmem` value is 256 in the example. The value for `usedmem` is 0 when the flow table does not have any flow records.
