Hi,

We are using Zabbix to monitor bandwidth usages. So we have created custom graph for motherly bandwidth. We need reset graph data for every month. So we have reset graph data( cleared history and logs). but graph still keeping old data.

For example: We have used 5TB bandwidth for previous month. So we have reset previous month bandwidth data. Again graph calculated from 5TB..not start with 0MB.

So we know how to reset this data and start from fresh value. We are using zabbix 3.4.7 with centos7 server.

Could you please advise?

Thanks
