Meaning of the colors in the solrcloud view

[Markus.Mirsberger]

Hi,

can someone give me a hint about the meaning of the different colors 
inside the cloud admin view graphics? I see oange, yellow, gray colors 
but dont find anything in the documentation about the meaning 
(especially the gray color:) ).

I have an external zookeeper server with 4 nodes (2 shards with 2 
replications) and suddenly the following effect (everything worked fine 
for a few days):

- I have 3 collections already running with data and for every 
collection the graphic shows me now one serveraddress in gray color.
- When I try to create a new collection through the collection api the 
cores will be created on all servers except one ( the same shown in 
other collections in gray color)

I already restarted the servers. I also tried to  clean the zookeeper 
data, upload my configurations again and restart everything. Always the 
same effect.


Thanks,
Markus
