Probe är konfigurerad till DOWN

Konfigureras i probe-filen, se probe fil konfiguration):

[ { "name" : "vp-camel", "url" : "http://ine-tit-app04.sth.basefarm.net:8080/status", "probeAvailable" : false, "probeMessage" : "StatusProbe probeFile signals DOWN, no check against producers will be performed", "serviceAvailable" : false, "serviceMessage" : null, "connecttimeout" : "1000", "responsetimeout" : "2000" } ]

Probens probe-fil är borttagen

[ { "name" : "vp-camel", "url" : "http://ine-tit-app04.sth.basefarm.net:8080/status", "probeAvailable" : false, "probeMessage" : "Configured probeFile /var/spool/vp-camel/probeFile does not exist, StatusProbe signals unavailable when file is missing.", "serviceAvailable" : false, "serviceMessage" : null, "connecttimeout" : "1000", "responsetimeout" : "2000" } ]
