Alerta Contrib

Useful but non-essential additions to the alerta monitoring system which are grouped together as follows:

• monitors - alert sources eg. ping script, SNMP traps, Syslog, URL monitor

• plug-ins - pre-receive and post-receive server hooks

• listeners - programs that listen for alerts forwarded by the server to AMQP or SQS queues

Example - How to use the AMQP Plug-in with RabbitMQ

Standard monitors for Syslog, SNMP and ping send alerts to the Alerta sever. Once the database is updated, the AMQP plug-in forwards the alerts to RabbitMQ. Different components listen for these alerts either on a dedicated queue or a shared topic, reformat the alerts and send IRC messages, emails or alerts to Pagerduty based on alert attributes.
