@Quazz We only have 3 images, and currently we are deploying the 32bit one. All the images are the same. plus this image in particular, is the one that was captured, as it is on the subnet where the master node resides.
Tomorrow i will be back at the building, so I will be able to dive into it more.
@george1421 host lookup from the server is different, it doesn’t use port 80. It uses some ICMP query that you’d probably know more about than me. It’s not a standard ping, and is faster and returns more than response/fail.
I wrote a script that monitors fog storage nodes. If they are up, they are enabled in the db. If they are down, they are disabled. You can also specify if you want the graph turned off or on as well for the on-line ones.
At work, we have a 15-server fog system. Down time was a real pain, it really messed with a lot of things, hence why I wrote this little script. You’d schedule it with CRON, I have ours set to run every 3 minutes.
