Introduction
The azeti Distributed Monitoring (DM) Technology is a key feature of the azeti SONARPLEX. Its application area is the monitoring of multiple remote sites (following called “Sattelite”) where the overall status is collected in one central SONARPLEX (following called “NOC”).
...
The distributed monitoring uses two concepts for delivering information to the NOC. Both include different data and are scheduled differently.
Example Architecture
Below is an example scenario for monitoring a distributed monitoring setup using the azeti Agent as delivery technolgy. This is a worldwide setup where every location can also have a sub location. All status information and alerts are collected in "Central Office".
...
Each SONARPLEX communicates with the remote devices through the azeti Agent, which is installed on the devices by default. To save bandwidth and system performance, static information ( is sent regularly and updates are done incremental.
Status File Delivery
| Delivery Technology | azeti Agent |
|---|---|
| Scheduling | regularly every n minutes |
| Data Content | overall status and monitoring configuration |
| Example Setup | SONARPLEX to SONARPLEX SONARPLEX to azeti Agent |
| Log Files | Distributed Monitoring (NOC Processor) [process_satellite.log] Distributed Monitoring (Satellite Processor) [send_status.log] Distributed Monitoring Event Log (NOC) [event.log] |

- hosts
- downtimes
- comments
- performance data
Status File Processing
The status file is automatically parsed and processed on the receiving system if it is a SONARPLEX.

See the Reports :: Event Log in the user web interface for better understanding of the processing, all the external commands are logged there after the receipt of a recent status file. |
Event Delivery
| Delivery Technologies | azeti Agent, SNMP Traps |
|---|---|
| Scheduling | on every occurrence of an event |
| Data Content | Event information. See List of Events for detailed information |
| Example Architectures | SONARPLEX to SONARPLEX SONARPLEX to azeti Agent SONARPLEX to SNMP Trap Receiver (Northbound Integration) |
The second concept is the Event Delivery. Every new event is immediately delivered, after it was processed internally, to the configured destinations. It depends on the delivery technology how the event is processed on the NOC side.
Understanding the difference between Alerts and Notifications
It is important to understand the difference between the event types. Alerts and notifications are the most important ones. Especially for the distributed monitoring environment it is crucial to deliver the appropriate event types to avoid unnecessary events and of course to make sure every important event is delivered to the NOC.
