Events & Alarms

Introduction

All N-Squared Applications running under the n2svcd framework generate:

• Events (WARNING or NOTICE) related to a single “event”, and/or
• Alarms (ALARM or CLEAR) which flag an ongoing alarm state, and/or
• Debug Tracing which can be turned-on to investigate specific problems.

There are several different mechanisms which can be used to access these outputs.

This section of the document describes the configuration and use of these different mechanisms.

Events & Alarms

Events & Alarms are always triggered by the applications. However, configuration can be used to control the mechanisms and destinations to which these Event & Alarm logs are pushed.

The possible destinations for Alarms & Events generated by n2svcd are:

1. The STDERR output of the n2svcd process,
2. The in-memory tracing system accessible via the management GUI or API,
3. The Linux Syslog,
4. The Linux snmptrapd or other process which accepts SNMP (v2c/v3) traps.
