incorrect connection string to mongo

[Ivan Berezovskiy]

1. Cluster HA
2. CentOS or Ubuntu
3. Nova or neutron
4. Install Ceilometer
5. 2 Controllers+mongoDB

Go to /etc/ceilometer/ceilometer.conf and take a look on connection:

connection=mongodb://ceilometer:ztKiS02z@192.168.0.3,192.168.0.2,/ceilometer

So connection string is formed for 3 nodes with mongo, but I have only 2 nodes in my env. So need to check count of mongo nodes and do not put comma at the end of hosts.

I reproduced this on 442 ISO.

    Fix mongo db nodes collection

    We should not put a comma at the end of mongo db nodes list.
    Because current mongo implementation supports max 3 mongo nodes,
    fix the cases for # of mongo nodes < 3.

    Closes-bug: #1311088
