Issue/Introduction

Error creating watch:

SPC-WCH-20072: This is a user defined error.

 

Environment

DX NetOps Spectrum all supported releases

Cause

1. The fgHaStatsMasterSerial and fgHaStatsSerial attributes have two instances so Spectrum couldn't isolate the correct one with the settings of .# and Instance None These were causing the SPC-WCH-20072: This is a user defined error.
   
   
2. The fgHaStatsMasterSerial and fgHaStatsSerial are external attributes, they are not Database and/or Memory (internal attributes). Hence Evaluate On Change cannot be selected in the Properties tab, in Evaluation, otherwise, the following error will be displayed:
   
   SPC-WCH-20059: Invalid watch: At least one attribute of a IMT watch must have the database and/or memory flag(s) set.
   
   
3. The watch Name cannot have space, like: Fortigate Failover
   
   It should be: Fortigate_Failover

 

 

 

Resolution

In the Expression tab set:

Data Type  : Text String

Expression : fgHaStatsMasterSerial.1

Instance   : None

In the Properties tab:

Default Activation: (disabled) Active by Default

Evaluation: Evaluate By Polling (because fgHaStatsMasterSerial and fgHaStatsSerial are external attributes)

In the Threshold tab:

Enabled Attach a Threshold

Threshold violated if value == fgHaStatsSerial.1

Threshold reset if value != fgHaStatsSerial.1

Notification: Generate Alarm
