The new INFRAUTILS-33 OpenDaylight status /diagstatus URL healthcheck is dev complete upstream in ODL, and about to be merged there.  This BZ issue should then be re-assigned to someone else than me who can take care of the required TripleO healthcheck URL change and impact handling.

The current implementation needs some more fixes. The status returned should be 503 Service unavailable. Right now HTTP GET always returns 200, and HTTP HEAD gives 418 and then hangs when a node is isolated:

[root@controller-0 ~]# curl -i -X GET http://172.17.1.14:8081/diagstatus && curl -i -X HEAD http://172.17.1.14:8081/diagstatus --max-time 5
HTTP/1.1 200 OK
Content-Type: application/json;charset=utf-8
Content-Length: 132

{
  "timeStamp": "Tue Aug 21 21:20:07 UTC 2018",
  "isOperational": false,
  "systemReadyState": "FAILURE",
  "statusSummary": []
}
HTTP/1.1 418 418
Content-Type: application/json;charset=utf-8
Content-Length: 132

curl: (28) Operation timed out after 5001 milliseconds with 0 out of 132 bytes received

Fixes have just been proposed upstream, and should trickle downstream eventually.

The patches have been back-ported d/s https://code.engineering.redhat.com/gerrit/#/q/topic:1566080+(status:open+OR+status:merged) but we'll get them for free the next time we rebase on Oxygen.

According to our records, this should be resolved by opendaylight-8.3.0-3.el7ost.  This build is available now.

Lon, looks like you got this wrong, could that be?  According to https://brewweb.engineering.redhat.com/brew/packageinfo?packageID=54522 (which Tomas just showed me), opendaylight-8.3.0-3.el7ost was built on 2018-08-07 but https://code.engineering.redhat.com/gerrit/#/c/148168/ (and the others listed above) were only merged Sep 5 - so this didn't make it into 8.3.0-3 but 8.3.0-4.... I'm therefore adjusting the Fixed In Version accordingly.

Could someone who understands the process better than I do update the Status?
