Issue while integrating Alerta with alertmanager

[MobinAnsari]

Hi Ramshankar,

I have installed alerta using your playbook. uwsgi service is running but getting below error in logs:

2018-04-26 18:25:49,412 - alerta.plugins[22901]: ERROR - Server plugin 'customtimeout' could not be loaded: cannot import name app [in /usr/lib/python2.7/site-packages/alerta/utils/plugin.py:33]

Further, We are using one different server for Prometheus(Working on Port 9200) and one different server for Alertmanager(Working on Port 8080) and one seperate server for Alerta.

I have tried to integrate Alerta with Alertmanager.
Modify the alerta configuration ( /etc/alertad.conf )
Added the alertmanager end point
ALERTMANAGER_API_URL = 'http://172.26.14.6:8080'

I have created the Alerta API key and added the same in alertmanager.yml file.

receivers:
- name: 'default-notifier'
webhook_configs:
- url: 'http://10.157.9.166:80/api/webhooks/prometheus?api-key=GHPosk54asfkjkhfA51IOli'
send_resolved: true

But I am little bit confused what I have to write in place of localhost and port(8080) that is defined in url section.
As per my understanding, I have added IP address of my Alerta Server and Port 80 but no data is coming in Alerta Dashboard.

Could you please help me to sort out the issue ?
