Alexander Kukushkin 188741de5a Merge branch 'master' of github.com:CyberDem0n/governor into restapi 2015-05-24 09:02:42 +02:00
Alexander Kukushkin ce267d9f1e query method will retry only in case of communication error 2015-05-24 09:01:23 +02:00
Alexander Kukushkin d202f72a42 Added simple web server which shows current state of postgres 
Server always returns json which contains some status of postgres:
* instance type: master/slave
* xlog location for master
* xlog received_location, replayed_location
This server could be used by haproxy
GET / returns 200 if there is postgres master behind governor.
GET /slave returns 200 is there is postgres slave behind governor
In all other cases it returns 503
Currently server always listening on 0.0.0.0:8080, but it should be
configurable. In the next versions this rest api could also report some
status of etcd and could be used by is_healthiest_node method
 2015-05-23 20:29:51 +02:00
Alexander Kukushkin f53c369c69 Connect timeout 5 seconds for psycopg2 
Refactored query and is_healthiest_node methods
query method wont retry more then 3 times if OperationalError raised
is_healthiest_node takes into account that one of the nodes could be
still a master
