Conditional Alarms for Arista Traps for entity sensor not alerting on Spectrum

Products

• CA Spectrum

Issue/Introduction

We have several Arista devices monitored in our environment and we observed that several traps are received for temperature from an entity but it never alerted.

Event 6710003 configured with conditional severity to alert if variable 4 has value 2,3 or 4 and clear if variable hold value 0. But it did not alert even after multiple traps with variable 4 holding value 4 in these traps.

 

 

Environment

Release : 10.4.1

Component : Spectrum Core / SpectroSERVER

Cause

1.3.6.1.2.1.131.1.1.1.5  ( entStateAlarm ) is of type EntityAlarmStatus.  
Again EntityAlarmStatus is of type BITS  which takes values  { unknown(0), underRepair(1), critical(2), major(3), minor(4), warning(5), indeterminate(6) }. 

The Event conditions are existing only for critical(2), major(3), minor(4) severity types.

Bit 2  or critical(2)  at device  corresponds to value 32  in which case  Spectrum generates Major alarm  ( 0x6710005  )
Bit 3  or Major (3)  at device  corresponds to value 16 in which case  Spectrum generates Minor alarm  ( 0x6710006  )
Bit 4  or Minor (4)  at device  corresponds to value 8 in which case  Spectrum generates Minor alarm  ( 0x6710007  )

0x6710003 E 20 A { v 4 Arista.aristaEntSensorAlarm },0x06710003 R CA.EventCondition, "({v 4} == {O 32})" , "0x6710005 -:-","({v 4} == {O 16})" , "0x6710006 -:-","({v 4} == {O 8})" , "0x6710007 -:-"

Resolution

These are the possible values for this trap:

1.3.6.1.2.1.131.1.1.1.5 ( entStateAlarm ) is of type EntityAlarmStatus.
Again EntityAlarmStatus is of type BITS which takes values { unknown(0), underRepair(1), critical(2), major(3), minor(4), warning(5), indeterminate(6) }.

Spectrum only alarms on critical(2), major(3), minor(4)
