there is no way in the source to switch off removing dead hosts at shutdown, because the cluster information is not persistant (is just in memory until the gmond process that contains it dies). what you would need to do is to make that information persistant (be written to disk before shutdown and reloaded from disk at startup) or just don't restart gmond. > The second question is: is that possible to add nodes which are not > reporting yet (no gmond installed) and see them in nodes list like > "not installed" or "not reporting"? E.g. how to create empty RRD record > for the new host, give it a hostname and make it visible in statistics? sort of. you could define a string metric with the value you want "not installed/running" and spoof an update to that metric from the host that is not yet installed (assumming the IP and DNS has been allocated already and you are using UDP and have access to raw sockets) with a gmetric like tool that you'll need to write and run as root.
