Graph calculation problem

[lamersons]

Every day, during high traffic(~1gbit), zabbix graph messes up. The graph looks like it's cutting the top. Looks like it has something to do with messed up calculations of latest traffic speed.

Anyway im not sure what is going on, any ideas please ?

zabbix system is not loaded, monitoring few hosts.


Thank You

you are probably monitoring a 32bit snmp oid which overflows. try to switch to 64bit oid

Thanks m8 - true expert

For those like me just use SNMP key ifHCInOctets instead of ifInOctets.
