Dashboard graphs stop updating suddenly.

[sbdcunha]

Dear All,

I have installed Zabbix 6.4.2 on Linux 8 and is working just great
But just 2 days I realized one of my dashboard the graphs have stopped updating since 2 days.

The dashboard group is fortigate and I have few graphs example CPU Util, uptime, Internet Traffic etc

Now when in Data Collection==>Hosts==>FortiGate==>Graphs I see 48 graphs
Now when i click on say the CPU Util graph and preview it its updated fine no issues and so also other graphs like uptime and internet traffic
But graphs under my Dashboard stopped updating 2 days .
But my other dashboard Graphs under Gobal View , datacenter are working perfectly fine and are updated to the latest time.
I tried deleting and recreating one widget under the FortiGate dashboard but same problem.
restarted the Zabbix server but no luck.
I attached 2 graphs here
1) uptime graph under data collection ==>Hosts==>FortiGate==>Graphs--- updated correctly
2) uptime graph under All Dashboards====>Fortigate ---- last update on 22-6-23
also I highlighted in yellow the difference in both graphs

Appreciate your help and advice.
if any more information required, please do ask

Thanks and regards

simon

What does the Latest data show for this item? Is the data coming ok?

Dear Glencoe,

Thanks for the reply.
As I said before the last update in the dashboard is 22-6-23 as I mentioned in Initial post.
But the graphs under data collection ==>Hosts==>FortiGate==>Graphs--- is updated correctly as on date
Its only in the new dashboard i created it has stopped.

Thanks and regards

Dear All

The issue has been fixed.
I deleted the Old dashboard and created a new one and then everything works fine.
All the graphs are updated properly.

Thanks and regards
