1.       The cache is available…

[root@trafficrouter ~]# more /opt/traffic_router/db/health.json
{"caches":{"lannion1":{"isAvailable":true},"paris1":{"isAvailable":true}},"deliv
eryServices":{"arte":{"disabledLocations":[],"isAvailable":true}}}


2.       Actually I did not implement a CZF, provided all went ok with a 
previous version. Could you confirm that it is necessary to have one?

{"locationByGeo":"not found","locationByFederation":"not 
found","requestIp":"172.20.3.199","locationByCoverageZone":"not found"}

Thank you
Yann

A couple of things:
1) in the Traffic Monitor UI can you click on CrStates and make sure your 
caches are available
2) In my experience ` rtype=MISS rloc="-" rdtl=DS_NO_BYPASS ` usually means 
that you missed on the CZF (you don't have one) and on the Geo-Location 
database.  If you put your source IP (172.20.3.199) into the Traffic Router 
API: http://<traffic_router>:3333/crs/stats/ip/172.20.3.199 and see what you 
get back?

Hi Eric,
I have attached a capture of the traffic monitor screen, but caches appear to 
be ok.
I was just wondering if a “null” hashId could be a possible cause, but I don’t 
know which mandatory data are consumed and tested by the core traffic router, 
before determining a valid cache server.
Thanks
Yann

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.

Thanks,
Eric

Hello,

I have some trouble understanding a problem with traffic router.

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

requête HTTP transmise, en attente de la réponse...503 Service Indisponible
2018-05-16 17:53:48 ERREUR 503: Service Indisponible.

The information in access.log is
qtype=HTTP chi=172.20.3.199 rhi=- 
url="http://tr.arte.traffic.inter-cdnrd.orange-business.com/ss/arte/mss_high.isml/Manifest";
 cqhm=GET cqhv=HTTP/1.1 rtype=MISS rloc="-" rdtl=DS_NO_BYPASS rerr="-" rgb="-" 
pssc=503 ttms=0,742 rurl="-" rurls="-" rh="-"

I guess the TR doesn’t find an available cache server but where could I find 
this information?

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 ?
(I don’t use a CZF and it is not clear to me why it could cause some problems. )
