Capturing PStack Trace on Unix for Autosys Scheduler, Application Server, Web Server (AEWS), WebUI/WCC and Collectors

Products

• Autosys Workload Automation

Issue/Introduction

When encountering a situation like the Autosys programs are not processing anything (example: scheduler does not seem to be processing events, application server is not processing requests, WebUI is taking up CPU but not letting any activity go by), collecting stack information from such programs will help Support and Engineering teams diagnose the issue at hand.

Resolution

WCC/WebUI

• To capture a stack trace with WebUI / WCC / WebUI collectors:

Main WCC:

count=1 
while [ $count -le 6 ]; do 
   echo "iteration $count out of 6,  sleeping 30seconds"
    kill -3 `ps -few|grep CA_WCC_INSTALL_LOCATION |grep -v grep |awk '{print $2}'`
   count=$((count+1))
   sleep 30
done

 

Collector:

count=1 
while [ $count -le 6 ]; do 
   echo "iteration $count out of 6,  sleeping 30seconds"
    kill -3 `ps -few|grep com.ca.wcc.collector.CollectorApplication |grep -v grep |awk '{print $2}'`
   count=$((count+1))
   sleep 30
done

 

• This sends the stack into the CA-wcc.log / collector logs
  
  
• Gather $CA_WCC_INSTALL_LOCATION/log folder (entire folder and its sub folders plus contents) and  $CA_WCC_INSTALL_LOCATION/collectors/WCC_COLLECTOR/log  folder (entire folder) 
  
  
• Provide them to Broadcom Support review

Scheduler / event_demon:

count=1 
while [ $count -le 6 ]; do 
   echo "iteration $count out of 6,  sleeping 30seconds"
    pstack `ps -few|grep "event_demon -A"|grep -v grep|awk '{print $2}'` > pstack_event_demon_$count.txt
   count=$((count+1))
   sleep 30
done

 

Application Server / as_server:

count=1 
while [ $count -le 6 ]; do 
   echo "iteration $count out of 6,  sleeping 30seconds"
    pstack `ps -few|grep "as_server -A"|grep -v grep|awk '{print $2}'` > pstack_as_server_$count.txt
   count=$((count+1))
   sleep 30
done

 

Web Server / AEWS:

count=1 
while [ $count -le 6 ]; do 
   echo "iteration $count out of 6,  sleeping 30seconds"
    pstack `ps -few|grep "AEWS"|grep -v grep|awk '{print $2}'` > pstack_AEWS_$count.txt
   count=$((count+1))
   sleep 30
done

 

Provide the pstack_*.txt files as well as $AUTOUSER/out/*   files for the problematic day in question for Support review.
