Hi,
I have this Backend pool to balance Neo4j Graph Database
the regular check to the port is not enough to know if the service is UP.
To be sure the server is Up I'm requesting something like
------
curl -X POST http://172.23.25.135:7474/db/data/ext/feed/graphdb/userFeed
-H "Content-Type: application/json" -d '{"userId":8, "offset":0,
"limit":1}' -v
and the response is
----
* About to connect() to 172.23.25.135 port 7474
* Trying 172.23.25.135... connected
* Connected to 172.23.25.135 (172.23.25.135) port 7474

{
"data" : {
"events" : [ {
"id" : "50ae98a29619de682e000000",
"userId" : 7334462,
"targetId" : 8,
"type" : 1
} ]
},
"success" : true
Connection #0 to host 172.23.25.135 left intact

-------------
I would like to check in the response
"userId" : 7334462
so I wrote
option httpchk POST /db/data/ext/feed/graphdb/userFeed
HTTP/1.1\r\nContent-Type: application/json\r\nContent-Length:
35\r\n{"userId":8, "offset":0, "limit":1}\r\n
to include the above line in the backend, but I have no clue how to
combine it with
http-check expect
Anyone can help me ?
Regards,
Owen
