NAME


flow-report — Generate reports from flow data.

SYNOPSIS


flow-report [-h] [-d debug_level] [-s stat_fname] [-S stat_definition] [-v variable
binding]

DESCRIPTION


The flow-report utility will generate reports from flow data. The reports are easy to
parse ASCII text that can be used by a front end to produce readable reports, graphs, and
charts.

Reports are definied in a configuration file by the 'stat-report' keyword followed by a
report name. Each report has a type defined below and other commands. Reports are
grouped into a definition with the 'stat-definition' keyword followed by a definition
name. Each definition can invoke a filter and optionally apply tags.

Words in the configuration file of the form @VAR or @{VAR:default} will be expanded at
run-time by setting variable names with the -v option.

Generated reports consist of comment lines and report lines. Comment lines begin with a #
and include details such as the options used, report name, records in the report, and the
report line format. Some of the more verbose comments can be controlled with the +header
and +xheader options. By default this information is not displayed. A column title
beginning with the string rec precedes the report lines. Report lines consist of key
fields, such as an IP address and calculated totals for that key such as the number of
flows.

The summary-detail report is a little bit different from other reports in that it has
multiple title lines and no key fields.

The column titles are described below.

+time_real Difference between the real time of the first and last
flow.
+aflowtime Total time of the flows / Total number of flows.
+aps Total Octets / Total Packets (Average Packet Size)
+afs Total Octets / Total Flows / (Average Flow Size)
+apf Total Packets / Total Flows (Average Packets / Flow)
+fps Total Flows / (Last End Time of Flow -
First Start Time of Flow) (Average Flows / Second)
+fps_real (Average Flows / Second in realtime)
+psizeN Average Packet Size buckets.
+fpsizeN Packets / Flow buckets.
+fosizeN Octets / Flow buckets.
+ftimeN Time / Flow buckets.

ignores Flows with a packet count of 0.

SSS-count Count of of an item, example source-ip-address-count

SSS* key fields, example source-ip-address
index Report line index.
first Time of first flow in unix_secs format.
last Time of last flow in unix_secs format.

flows Summation of flows/key.
octets Summation of octets/key.
packets Summation of packets/key.
duration End time of Flow - Start time of Flow.
avg-bps Average Bits/Second.
min-bps Minimum Bits/Second.
max-bps Maximum Bits/Second.
avg-pps Average Packets/Second.
min-pps Minimum Packets/Second.
max-pps Maximum Packets/Second.
frecs Records used in average calculations.

Note fields with a + are only available in the summary-detail report.

The PPS and BPS calculations will not always be correct due to flows which only have one
packet, or some other condition where the start time is equal to the end time. In this
case these flows are not used in the PPS and BPS calculations. To facilitate aggregating
multiple reports and retaining the PPS and BPS fields, the number of flows counted is
available in the frecs field.

IMPLEMENTATION NOTES


Packet size calculations are dOctets / dPkts, ie an average packet size. It is not
possible to get a true packet size from flow exports.

pps and bps calculations are an average of the averages.

Flows that do not have a duration (start == end) are not counted in the pps and bps
calculations.

Flows without a packet or octet count are ignored.
