Your boss is coming in and telling you that a technician needs a map with more than 250 hosts clearly laid out. You think: “Hey, that’s not possible, with a full description for every host!” The font in the background image is not the problem, but the std_small-iconset from NagVis is too big for such a request.
Build your own iconset.
A complete iconset consists of a number of files. These files are png, svg, gif or jpg images which are named like this:
| Filename | Description | 
|---|---|
| <set>_critical.png | Critical state | 
| <set>_critical_ack.png | Acknowledged critical state | 
| <set>_critical_dt.png | Critical state in downtime | 
| <set>_critical_stale.png | Stale critical state | 
| <set>_down.png | Down state (Host) | 
| <set>_down_ack.png | Acknowledged down state | 
| <set>_down_dt.png | Down state in downtime | 
| <set>_down_stale.png | Stale down state | 
| <set>_error.png | Error while fetching status | 
| <set>_ok.png | OK state | 
| <set>_ok_dt.png | OK state in downtime | 
| <set>_ok_stale.png | Stale ok state | 
| <set>_pending.png | PENDING state | 
| <set>_unchecked.png | Unchecked service (pending) | 
| <set>_unknown.png | Unknown state | 
| <set>_unknown_ack.png | Acknowledged unknown state | 
| <set>_unknown_dt.png | Unknown state in downtime | 
| <set>_unknown_stale.png | Stale unknown state | 
| <set>_unreachable.png | Unreachable state (Host) | 
| <set>_unreachable_ack.png | Acknowledged unreachable state | 
| <set>_unreachable_dt.png | Unreachable state in downtime | 
| <set>_unreachable_stale.png | Stale unreachable state | 
| <set>_up.png | Up state (Host) | 
| <set>_up_dt.png | Up state in downtime | 
| <set>_up_stale.png | Stale up state | 
| <set>_warning.png | Warning state | 
| <set>_warning_ack.png | Acknowledged warning state | 
| <set>_warning_dt.png | Warning state in downtime | 
| <set>_warning_stale.png | Stale warning state | 
<set>_ok.png image to list the iconsets,
        means there has to be at least a <set>_ok.png image to have a
        choosable iconset.
        Almost every graphic art software has the ability to build PNG-files. In this example Photoshop is used to create a smaller version of the std_small iconset called std_mini.
| Iconset | Icon size | icon map | 
|---|---|---|
| std_small | 16×16 pixel |  | 
| mini | 9×9 pixel |  | 
To implement the set in your NagVis installation, copy all files to
         the iconset folder (share/userfiles/images/iconsets).
Open one of your maps and add a new host-icon. You should now be able to select std_mini as iconset.
