Thanks a lot for your detailed reply Preben! The "sendEmptyMessageWhenIdle" option sounds exactly what I was looking for. The other option you mention sounds interesting as well. How can I make a context/route report its health state via JMX? I know that Camel can be queried and controlled via JMX but how would it be possible to, e g, detect that the ftp component has stopped polling?
Or perhaps you mean that I would detect it using the " sendEmptyMessageWhenIdle" but report it via JMX? In my case I need to use Nagios in a passive configuration since we do not allow incoming traffic to the server. Therefore my Camel routes need to actively report both failures and heartbeats. A REST API won't fit the bill. /Bengt 2013/2/11 Preben.Asmussen <p...@dr.dk> > Hi Bengt > > On file endpoint you can enable sendEmptyMessageWhenIdle option that sends > an empty message if no files are available.
