the network plugin uses UDP, which is an "unreliable" protocol. That means that if the server is not available / doesn't receive the data for whatever reason, the client won't even notice. I.e. the data is simply lost. > If not, how can I overcome this? > Have you guys already in this situation? Right now there is no plugin that buffers and retransmits in this scenario. You can get more reliable transmissions using AMQP, for example, but if the client–broker connection is lost, collectd will drop data in that setup, too.
