[root@support libexec]$ ./check_snmp_traffic 172.16.1.8 public 1 ">200" ">400"
Traffic OK - .01 Mb/s in Sum|traffic=.01;>200;>400;0; In=.01;;;0; Out=0;;;0;

OUTPUT IS:-
IF-MIB::ifName.1 = STRING: Vl1
IF-MIB::ifName.5049 = STRING: Lo0
IF-MIB::ifName.10101 = STRING: Gi0/1
IF-MIB::ifName.10102 = STRING: Gi0/2
IF-MIB::ifName.10103 = STRING: Gi0/3
IF-MIB::ifName.10104 = STRING: Gi0/4
IF-MIB::ifName.10105 = STRING: Gi0/5
IF-MIB::ifName.10106 = STRING: Gi0/6
IF-MIB::ifName.10107 = STRING: Gi0/7
IF-MIB::ifName.10108 = STRING: Gi0/8
IF-MIB::ifName.10109 = STRING: Gi0/9
IF-MIB::ifName.10110 = STRING: Gi0/10
IF-MIB::ifName.10111 = STRING: Gi0/11
IF-MIB::ifName.10112 = STRING: Gi0/12
IF-MIB::ifName.10113 = STRING: Gi0/13
IF-MIB::ifName.10114 = STRING: Gi0/14
IF-MIB::ifName.10115 = STRING: Gi0/15
IF-MIB::ifName.10116 = STRING: Gi0/16
IF-MIB::ifName.10117 = STRING: Gi0/17
IF-MIB::ifName.10118 = STRING: Gi0/18
IF-MIB::ifName.10119 = STRING: Gi0/19
IF-MIB::ifName.10120 = STRING: Gi0/20
IF-MIB::ifName.10121 = STRING: Gi0/21
IF-MIB::ifName.10122 = STRING: Gi0/22
IF-MIB::ifName.10123 = STRING: Gi0/23
IF-MIB::ifName.10124 = STRING: Gi0/24
IF-MIB::ifName.10125 = STRING: Gi0/25
IF-MIB::ifName.10126 = STRING: Gi0/26
IF-MIB::ifName.10127 = STRING: Gi0/27
IF-MIB::ifName.10128 = STRING: Gi0/28

But, monitoring Gi0/24 interface gives below error.

[root@support libexec]$ ./check_snmp_traffic 172.16.1.8 public 24 ">200" ">400"

Traffic UNKNOWN - Mb/s in Sum|traffic=;>200;>400;0; In=;;;0; Out=;;;0;

I need a common plugin thru which I can monitor all SNMP enabled network devices graph i.e. CIsoc, Fortigate, Juniper, Windows & Linux OSes.

You are basing your math from the sleep timer. However you're forgetting that the snmpget can take longer than 0 seconds, which means that when the second trafbyteOut check runs, it has not been 0 seconds since the sleep of 1 second.

What you'll want to do is get the current times and compare the two.
