calculation is based on MUST also be part of the filter string or
decimal separator is set to "."! If it is set to "," the statistics
will not be displayed per filter.
-COUNT(<field>) can be used on any type which has a display filter name.
-It will count how many times this particular field is encountered in the
-filtered packet list.
+B<COUNT(I<field>)I<field> [and I<filter>]> - Calculates the number of times that the

-Example: B<-z io,stat,0.010,COUNT(smb.sid)smb.sid>
+Example: B<-z io,stat,0.010,E<34>COUNT(smb.sid)smb.sidE<34>>
This will count the total number of SIDs seen in each 10ms interval.
-SUM(<field>) can only be used on named fields of integer type.
-This will sum together every occurrence of this field's value for each interval.
-
-Example: B<-z io,stat,0.010,SUM(frame.pkt_len)frame.pkt_len>
-
-This will report the total number of bytes seen in all the packets within
-an interval.
-
-MIN/MAX/AVG(<field>) can only be used on named fields that are either
-integers or relative time fields. This will calculate maximum/minimum
-or average seen in each interval. If the field is a relative time field
-the output will be presented in seconds and three digits after the
-decimal point. The resolution for time calculations is 1ms and anything
-smaller will be truncated.
-
-Example: B<-z "io,stat,0.010,smb.time&&ip.addr==1.1.1.1,MIN(smb.time)smb.time&&ip.addr==1.1.1.1,MAX(smb.time)smb.time&&ip.addr==1.1.1.1,MAX(smb.time)smb.time&&ip.addr==1.1.1.1">
-
-This will calculate statistics for all smb response times we see to/from
-host 1.1.1.1 in 10ms intervals. The output will be displayed in 4
-columns; number of packets/bytes, minimum response time, maximum response
-time and average response time.
+B<SUM(I<field>)I<field> [and I<filter>]> - Unlike COUNT, the I<values> of the
+specified field are summed per time interval.
+''I<field>'' can only be a named integer, float, double or relative time field.
+
+Example: B<-z io,stat,0.010,E<34>SUM(frame.len)frame.lenE<34>>
+
+Reports the total number of bytes that were transmitted bidirectionally in
+all the packets within a 10 millisecond interval.
+
+B<MIN/MAX/AVG(I<field>)I<field> [and I<filter>]> - The minimum, maximum, or average field value
+in each interval is calculated. The specified field must be a named integer,
+float, double or relative time field. For relative time fields, the output is presented in
+seconds with six decimal digits of precision rounded to the nearest microsecond.
+
+In the following example, the time of the first Read_AndX call, the last Read_AndX
+response values are displayed and the minimum, maximum, and average Read response times
+(SRTs) are calculated. NOTE: If the DOS command shell line continuation character, ''^''

=item B<-z> sip,stat[I<,filter>]
-This option will activate a counter for SIP messages. You will get the number

+=item B<-z> mac-lte,stat[I<,filter>]
+
+This option will activate a counter for LTE MAC messages. You will get
+information about the maximum number of UEs/TTI, common messages and
+various counters for each UE that appears in the log.
+
+Example: B<-z mac-lte,stat>.
+
+This option can be used multiple times on the command line.
+
+If the optional I<filter> is provided, the stats will only be calculated
+for those frames that match that filter.
+Example: B<-z "mac-lte,stat,mac-lte.rnti>3000"> will only collect stats for
+UEs with an assigned RNTI whose value is more than 3000.

+in the log.

+
+=item B<-z> expert[I<error|warn|note|chat>][I<,filter>]
+
+Collects information about all expert info, and will display them in order,
+grouped by severity.
+
+Example: B<-z expert,sip> will show expert items of all severity for frames that
+match the sip protocol.
+
+This option can be used multiple times on the command line.
+
+If the optional I<filter> is provided, the stats will only be calculated
+on those calls that match that filter.
+
+Example: B<-z "expert,note,tcp"> will only collect expert items for frames that
+include the tcp protocol, with a severity of note or higher.
