Issue with graphs on the dashboard

[donwito]

Hi All,

I'm experiencing a weird issue with graphs, but only on the dashboard. Example -

1. I have a host with multiple network interfaces, traffic data is correctly displayed for an interface:


2. Graphs are also correctly displayed when I get to them through "latest data":


3. But when I try to add this data as a graph on the dashboard, there's no data:


4. When I try Graph (classic) or Simple Graph, I get the data OK. It's only an issue with the "Graph" widget, which is actually most useful to me as it can display multiple datasets.


5. It seems that the issue only occurs for recently renamed or reconfigured items. The ISP connection was up until some point on port 1:24 and the graph was displayed ok. In another location I have recently activated 2 network ports on 2 devices and I have the same issue, graph widget comes up empty for those interfaces, while it does populate nicely for all other interfaces. But I am not sure how to verify that and how to troubleshoot further.

Any ideas will be most welcome. Thanks!

I once found that my Graphs were not showing up due to a browser ad-blocker. After adding the Zabbix URL to the blocker's whitelist, the Graphs were displayed correctly. Do you use one?

Hey markfree

Thanks for responding & sorry foir getting back to you so late. I have misconfigured my notifications and totally missed your response.
I have checked on 3 different browsers, also the ones without any adblockers. No change.

Hi donwito

Did you make any progress on this?
I'm seeing the exact same behaviour and am stumped so far.

I had the same problem and stumbled upon this post while looking for an answer.

I fixed it by flagging the "Set Custom time period" in the time period tab, probably due to an accidental drag on the graph itself that lead to a custom time period.



Hope it helps
