Hi Yann- By going to the Traffic Monitor GUI, you can see a view of the health of the cache. The webpage will show each cache on a separate row with current values for liveness, load avg and bandwidth.
You may also want to check the error log on Traffic Monitor to see if its having any issues reaching the edge cache astats endpoint. The current configuration you have below assumes that the edge cache is listening on the eth0 interface.

After installing a new TR (version 2.1), I can’t make it work for a simple HTTP delivery service (service name = arte – CDN name = traffic). wget http://tr.arte.traffic.inter-cdnrd.orange-business.com/ss/arte/mss_high.isml/Manifest --2018-05-16 17:53:48-- http://tr.arte.traffic.inter-cdnrd.orange-business.com/ss/arte/mss_high.isml/Manifest Résolution de tr.arte.traffic.inter-cdnrd.orange-business.com<http://cdnrd.orange-business.com/> (tr.arte.traffic.inter-cdnrd.orange-business.com<http://cdnrd.orange-business.com/>)... 172.20.3.200 Connexion vers tr.arte.traffic.inter-cdnrd.orange-business.com<http://cdnrd.orange-business.com/> (tr.arte.traffic.inter-cdnrd.orange-business.com<http://cdnrd.orange-business.com/>)|172.20.3.200|:80...connecté. requête HTTP transmise, en attente de la réponse...503 Service Indisponible 2018-05-16 17:53:48 ERREUR 503: Service Indisponible.

For example, the following TR API http://trafficrouter.tc.inter-cdnrd.orange-business.com:3333/crs/locations/Lannion/caches seems to point out that there would be no available bandwidth from the cache. {"caches":[{"cacheId":"lannion1","fqdn":"lannion1.tc.inter-cdnrd.orange-business.com<http://lannion1.tc.inter-cdnrd.orange-business.com/>","ipAddresses":["172.20.3.198"],"port":0,"adminStatus":null,"lastUpdateHealthy":false,"lastUpdateTime":0,"connections":0,"currentBW":0,"availBW":0,"cacheOnline":true}]} Could it be the reason why no cache is found/used by traffic router ? I am wondering if the CR config below is ok ?
