Proxy Devices Created During TSM discovery.

Products

• VMware Smart Assurance
• VMware Telco Cloud Service Assurance

Issue/Introduction

Symptoms:

• Proxy Devices are generating Unresponsive events even though they respond to Ping and SNMP requests.
• These Proxy devices are created during TSM discovery and sent to the IP domains from TSM.
  
  

Environment

SMARTS - 10.1.x

SMARTS - 2.X

TCSA - 2.X

Cause

Proxy devices created by TSM for Root Cause Analysis were incorrectly instrumented.

See the resolution below changes are required in Polling and Thresholds to remove instrumentation and the conf/icf/settings.conf file to resolve issue.

Resolution

1. Go to, Polling and Threshold > Polling tab > Proxy Devices group > Matching Criteria tab, and remove the following criteria:
     
IsProxy = TRUE.

and add the following matching criteria.  
DOMAIN = *Proxy*

Then in your IP installations you will need to use sm_edit on the ../conf/icf/settings.conf file and find the following section:

###############################
#
# System Polling Configurations
#
###############################

polling category ICIM_UnitaryComputerSystem Polling Groups
match   IsManaged TRUE

config  ComputeFabric
match   IsMemberOfComputeFabric TRUE

config  Proxy Devices
match   IsProxy TRUE

Change the line
match   IsProxy TRUE
to
match DOMAIN Proxy

2.Save the changes,

You should now have an updated settings.conf file in your <Basedir>/IP/smarts/local/conf/icf/ folder

3.Trigger discovery on the underlying APM domains.

NOTE: These steps need to be done for the all the APM domains that are feed or updated by TSM in your environment.

Additional Information

In order to preserve the P&T settings for the Domain Proxy in APM after the restart the of the APM domains it is a requirement to make sure the updates to the <Basedir> /IP/smarts/local/conf/icf/settings.conf file are saved.
