graph not showing correct value

[sisirtiwari]

I use zabbix 3.2.6 and i have created graph for traffic usage on each interface but it doesn't shows a correct value however the graph shown by other monitoring tools like cacti is correct. Also zabbix's graphs doesnt shows the value in bits/sec.

That sounds like you want to add a unit "bps" to that item and perhaps add multiplier, if necessary.

i used unit as bps and multiplier as 8 in an item. Traffic on most of the ports are more than 2-3gbps but in zabbix the graph shows only 200Mbps-300Mbps.

Counters values are not coming correct usually happens when at the time of creation of item "Store Value" parameter is set as "As is" instead of "Delta (speed per second)".

Change the above parameter for solution. Revert in case of any issues.

Thankyou Akansha for your reply. I also think that's a counter problem but how can i solve that issue. Also i have used store value as Delta(speed per sec) but didn't get correct graph. for your information please see attachment about item configuration for interface monitoring of raisecom switch.

solved. have to use snmp oid as ifHCInOctets instead of ifInOctets.
ifHCInOctets is 64-bit counter and ifInOctets is 32-bit counter.
