Notifications

Types of Notifications

SNMP

The azeti server is able to send any event as an SNMP trap (version 2c) to the defined receiver. The format of the message is the following:

  • Trap OID = 1.3.6.1.4.1.34540.14.5.110
    • 1.3.6.1.4.1.34540.14.5.110.1: output of the sensor
    • 1.3.6.1.4.1.34540.14.5.110.2: sensor name
    • 1.3.6.1.4.1.34540.14.5.110.3: state of the sensor (Critical, Ok, etc.)
    • 1.3.6.1.4.1.34540.14.5.110.4: Timestamp of the event
    • 1.3.6.1.4.1.34540.14.5.110.6: Location name

Email


If an email server is configured then email can be used as a mean to send the notification. An example of an email notification is the following:

Dear customer,

this is an eMail notification from Azeti Social Sensor Cloud.

Alert recovered:

State:		WARNING
Output:		Virtually setted... 69.70 
Time:		Nov 24, 2015 20:24:36 PM

Azeti SSC platform

SMS

When connected to an SMS sending platform, the system can also send the events as SMS. The same information as other notifications is sent:

Slack

Slack is a group messaging app, that can be found in https://slack.com/ The azeti server can send notifications via this app, provided it has access to the slack cloud server over the Internet.
