 Description   

Steps to reproduce:

  1. Navigate to Monitoring > Hosts
  2. Search for a host with more than 20 graphs, e.g. 50.
  3. Select "Graphs" of that host.

Result:
Only 20 graphs of that host are shown and on top you see the time filter tab.
There is no indication that there are more graphs available. No pages, no warning, no "showing only X of Y graphs".
To see the other graphs, you need to filter them in the graphs search bar of the filter tab.

Expected:
Either show all graphs of that host on a single page or multiple pages.
Or show only 20 graphs of that host and indicate that there are more graphs available.

Hello h.l.,

The limit of 20 graphs was created to not spike the performance too much.
If you want to see more graphs on this page, you can update define value for ZBX_MAX_GRAPHS_PER_PAGE .
The total amount of graphs you currently can see in Monitoring->Hosts page and the remaining graphs can be accessed by selecting them in filter. Select popup contains list of all graphs.

Also I can note, that design for page Monitoring->Hosts->Graphs is still being discussed and may be updated in future.

Hello Valdis Murzins,

I understand the reason why graphs where limited and that I am able to change it with ZBX_MAX_GRAPHS_PER_PAGE. Thanks for the hint. But my report is about the missing indication, that there are graphs missing on the page. So it is about usability on a enduser perspective. If graphs are cut out, a small hint would solve this issue. Users may don't know/find/edit the value of ZBX_MAX_GRAPHS_PER_PAGE and thus complain about missing graphs. Even if I change ZBX_MAX_GRAPHS_PER_PAGE to lets say 100, we would have performance issues and there might still be Hosts with more than 100 graphs. Zabbix uses already hints e.g. for missing alarms in the dashboard. So this would be a good solution.
Thank you,
Holger

Hi,

Yeah, graphs not showing how many there is and not having a page-functionality must be an oversight? If Zabbix is showing 20 graphs, how are you supposed to browse through the rest?

Hi carlmelgaard,

This is a design problem, although previously known and with plans to fix in with Graphs page redesign in ZBX-17748.
As for "how to browse through the rest": currently the list of all graphs available on the host is available in filter, when pressing "Select" button for "Graphs" multiselect. There you can select, which graphs you want to see.

I am sorry for this inconvenience.
