We have configured the data polling every 5 minutes as it is set in the configuration.
Recently we have activated the Fast Polling every 1 minute in order to detect any possible micro-cuts that may occur.
The problem that has arisen is that the Fast Polling does not seem to be working properly, since looking at the ping graphs of different devices we find gaps.
How many devices? It could be your fping settings. timeout and interval settings determine how long your system waits. Most of the time during fping is waiting, so it is unlikely to be any sort of resource issue.
