Issue/Introduction

This article explains the following:

• Setting up the sm_monitor command to collect data on Smarts SAM trap adapters. 
• Steps for running Smarts sm_monitor against an sm_trap process
• Commands to collect the Smarts SAM adapter trap rate and size of the trap adapter queue.
• Individual commands to collect information regarding threads, queues, stacktrace, and locktable information

For the purpose of: collecting data on trap adapters for troubleshooting Smarts SAM trap adapter and trap services issues

Environment

Smarts 10.x / 2.x

Resolution

To collect sm_monitor data on the trap adapter you can use the following command:

<BaseDir>/SAM/Smarts/bin/sm_monitor -b localhost:426 -s <TRAP-ADAPTER Domain Name> -S trapd -z -k -m mem -l 3 run-all

 

• The -S trapd command argument specifies that you are running a trap adapter. 
• The -l 3 (lowercase "L" 3) command argument tells the command to loop 3 times.
• When using this command, it is recommended to set up a cron job or scheduled task to run the sm_monitor command every 15 minutes

Furthermore, you can also run the latest sm_monitor against the sm_trapd process as follows:

./sm_monitor -s <trap-adapter> -S trapd

From this directory:

 <BaseDir>/SAM/Smarts/bin 

You'll want to collect the Smarts SAM adapter trap rate and size of the trap adapter queue by running the following command:

dmctl -s <TRAP-ADAPTER DOMAIN NAME> get SNMP_TrapManager::SNMP-Trap-Manager

To collect information specifically regarding trap adapter threads, queues, stacktrace, and locktable information, use the following commands:
 

./dmctl - s <trapd_domain-name> exec dmdebug --threads --output=threads.txt

./dmctl - s <trapd_domain-name> exec dmdebug --queues --output=queues.txt

./dmctl - s <trapd_domain-name> exec dmdebug --stacktrace --output=stacktrace.txt

./dmctl - s <trapd_domain-name> exec dmdebug --locktable --output=locktable.txt
