I am running Zabbix 1.4.4 on RHEL4. I am monitoring the traffic load on all the serial interfaces on my routers. Everything was running 100% until Saturday when 2 of the graphs suddenly only showed the outgoing traffic line. On investigation I found that the item that has been configured to get the incoming traffic has stopped getting the information. The latest data it has was on the 21st June. I have tried disabling it and re enabling it with no success. Is there something (other than reinstalling the entire system) I can do to wake the errant child up!!!

I have checked the "Latest data" and find that on a few of my graphs the "last check" shows that it is 4 days old and it stays there. Is there any way I can force it to restart checking??? -
That happens if SNMP agent can not pull out new data for some reason. It does not show null or undef. It shows last known value.
Use .nodata(<timesec>) trigger to detect that situation.Comment
