Also xls file contains the same formated information. Please use it.

We are using AIX perfstat API to get network interface statistics:

http://publib.boulder.ibm.com/infocenter/pseries/v5r3/index.jsp?topic=/com.ibm.aix.prftools/doc/prftools/prftools07.htm

Even using example programs from that document I get different results with what entstat is showing. entstat command manual:

http://pic.dhe.ibm.com/infocenter/aix/v6r1/index.jsp?topic=%2Fcom.ibm.aix.cmds%2Fdoc%2Faixcmds2%2Fentstat.htm

entstat has a switch to reset counters but I still can't find information on why perfstat data is different from what entstat or netstat -v show.

The question has been asked on IBM forum:

https://www.ibm.com/developerworks/forums/thread.jspa?threadID=439697

It appeared that entstat views device driver statistics while perfstat API views network interface statistics. In order to view the same statistics zabbix agent returns compare them to what

netstat -D -I <device>

returns (e. g. netstat -D -I en2). These numbers should be identical, please check.
