Is there any way to show the weathermap when a host was down?
For example, changing the color of the image to red?

(you know you can just click 'Watch This Topic' at the bottom, right?  )
As long as you trust Cacti to decide what host is down (I don't - I use other software for availability monitoring) then yes, it's easy.
It's discussed in this thread already, but here's the summary:
| Code: |
SCALE cactiupdown 0 0.5 192 192 192
SCALE cactiupdown 0.5 1.5 255 0 0
SCALE cactiupdown 1.5 2.5 0 0 255
SCALE cactiupdown 2.5 3.5 0 255 0
NODE myrouter
POSITION 100 100
LABEL My Router
TARGET cactihost:22
USESCALE cactiupdown in
|
So, the cactihost: target returns a number from 0 to 3 for disabled, down, recovering, or up, as the 'in' bandwidth value. The SCALE lines define a scale so that each of those is a different colour.
In the node, you use the cactihost: target with the hostid from Cacti - you can see this in the URL if you go to the Devices page and click on the device. Then you say to use the scale that you defined to look at the 'in' value and colour the node.
In 0.93 and newer, there is a cactimonitor: target too, that does the same thing with one extra state - 'thresholds failing' - so you can show devices that are "sick but not dead". Look up TARGETs in the config reference, and then look at the TARGET reference link there for more info.
If you want to use another source (e.g. Nagios) for the up/down info, then you need to do more work or write a plugin for weathermap. I intend to write some of those myself over the next few versions.

Here is a preliminary nagios datasource addon I wipped up.
Right now will return the following
0 - statename: up
1 - statename: down
2 - statename: unreachable
3 - statename: warning (means services impaired but host up)
100 - statename: unknown
I populate the variable state with the number as well.
nagioshost: <nagios alias> as your target
You will need the ndodb under the cacti database for this to work out of the box.
Again this is alpha and just using as proof of concept right now.
