With the LPAR Tool, SEA statistics can be displayed at any time with the command “vios seastat“. This allows you to determine at any time which client LPARs have which network throughput.
Which SEAs there are on a virtual I/O server can easily be found out using “vios lssea“:
$ vios lssea ms19-vio1 TIMES TIMES BRIDGE NAME HA_MODE PRIORITY STATE PRIMARY BACKUP MODE ent40 Sharing 1 PRIMARY_SH 1 1 Partial ent41 Sharing 1 PRIMARY_SH 1 1 Partial ent42 Sharing 1 PRIMARY_SH 1 1 Partial $
The only requirement is that accounting has been activated for the SEAs. This can be checked as follows:
$ vios lsattr ms19-vio1 ent40 accounting value enabled $
If accounting is disabled, it can be activated with the command “vios chdev“:
$ vios chdev ms19-vio1 ent40 accounting=enabled $
We can display the SEA client statistics with the command “vios seastat“. By default, the data for all SEA clients of the specified SEA, ent40 in the example, is shown every 10 seconds:

Statistics are saved on the virtual I/O server for each combination (LPAR, MAC address, VLAN, IP address). The LPAR aixmqt01 in the example above has e.g. 2 different IP addresses (3.XX31 and 3.XX32) in VLAN 155 on the same interface (with the MAC address 32: XX: XX: XX: XX: 05) . If it is not of interest which of the IP addresses of an LPAR generates the traffic, the data can also be added up with the option ‘-C‘ (coalesce). With ‘-C vlan‘ for example, all data records for the same VLAN and the same MAC address (and thus the same LPAR) can be aggregated:
$ vios seastat -C vlan ms19-vio1 ent40 LPAR_NAME MAC VLAN IN_PKTS IN_BYTES OUT_PKTS OUT_BYTES aixmqt01 32:XX:XX:XX:XX:05 155 573.03/s 77.23 KB/s 443.19/s 99.85 KB/s aixdbprod3 B6:XX:XX:XX:XX:05 200 66.98/s 13.08 KB/s 88.62/s 15.84 KB/s ms19-vio2 0A:XX:XX:XX:XX:05 725 8.42/s 0.92 KB/s 0.00/s 0.00 B/s ms19-vio2 0A:XX:XX:XX:XX:06 700 8.42/s 0.92 KB/s 0.00/s 0.00 B/s … LPAR_NAME MAC VLAN IN_PKTS IN_BYTES OUT_PKTS OUT_BYTES aixmqt01 32:XX:XX:XX:XX:05 155 581.17/s 79.30 KB/s 480.71/s 108.78 KB/s aixdbprod3 B6:XX:XX:XX:XX:05 200 92.32/s 21.33 KB/s 114.00/s 21.45 KB/s ms19-vio2 0A:XX:XX:XX:XX:05 725 5.69/s 0.80 KB/s 0.00/s 0.00 B/s ms19-vio2 0A:XX:XX:XX:XX:06 700 5.69/s 0.80 KB/s 0.00/s 0.00 B/s … ^C
With ‘-C mac‘ you can add up all data records with the same MAC address. If an LPAR has several virtual Ethernet adapters and thus different MAC addresses, you get one data record for each MAC address of the LPAR. Finally, you can also aggregate all data records of an LPAR and thus determine the total throughput of an LPAR over a certain SEA, by using the option ‘-C lpar‘:
$ vios seastat -C lpar ms19-vio1 ent40 LPAR_NAME IN_PKTS IN_BYTES OUT_PKTS OUT_BYTES aixmqt01 558.77/s 75.71 KB/s 448.14/s 104.75 KB/s aixdbprod3 51.93/s 11.06 KB/s 52.32/s 9.28 KB/s ms19-vio2 9.82/s 1.34 KB/s 0.00/s 0.00 B/s ms19-vio1 4.91/s 667.93 B/s 0.00/s 0.00 B/s … LPAR_NAME IN_PKTS IN_BYTES OUT_PKTS OUT_BYTES aixmqt01 581.30/s 80.22 KB/s 461.91/s 106.88 KB/s aixdbprod3 84.82/s 18.95 KB/s 82.66/s 15.83 KB/s ms19-vio2 12.57/s 1.64 KB/s 0.00/s 0.00 B/s ms19-vio1 6.28/s 0.82 KB/s 0.00/s 0.00 B/s … ^C
If you do not want to see data per client, but rather cumulatively per VLAN, this is possible with the ‘-V‘ option. This makes it easy to determine which VLANs are causing the most traffic:

As with “vios fcstat“, the number of data records shown can be limited with the option ‘-t‘ (top). Here only the top 3 data records with the highest activity (throughput) are shown:

If necessary, a different interval length (in seconds) can be choosen, instead of the default interval of 10 seconds. To do this, the desired interval length is simply specified as the last argument:
$ vios seastat -V ms19-vio1 ent40 2 VLAN IN_PKTS IN_BYTES OUT_PKTS OUT_BYTES 155 525.07/s 70.14 KB/s 415.09/s 88.41 KB/s 200 45.56/s 8.51 KB/s 44.64/s 7.66 KB/s 700 11.04/s 0.81 KB/s 0.00/s 0.00 B/s 725 5.52/s 404.96 B/s 0.00/s 0.00 B/s VLAN IN_PKTS IN_BYTES OUT_PKTS OUT_BYTES 155 540.14/s 73.11 KB/s 429.53/s 95.59 KB/s 200 64.06/s 15.69 KB/s 69.59/s 16.22 KB/s 700 3.69/s 0.76 KB/s 0.00/s 0.00 B/s 725 1.84/s 377.91 B/s 0.00/s 0.00 B/s ^C
For smaller interval length, the accuracy of the displayed values suffers somewhat. At 2 second intervals the inaccuracy is approx. 10%. However, the relationship between the displayed values is still correct.
