Use EICLASS to monitor and reduce the delay in CA Workload Automation ESP Edition

Products

• ESP Workload Automation

Issue/Introduction

Because of the delay in ESP Processing,. some requests may be processed out of order, causing unexpected result.

Environment

Release : 11.4 & 12.0

Component : CA ESP WORKLOAD AUTOMATION

Cause

Delays in event processing causing delay in batch processing.

Resolution

Following command will show the event/appl/job with highest CPU usage/maximum delays:

OPER EICLASS STAT

In the sample output below, "Highest elapsed time" indicates the maximum delay in related EICLASS initiator, it's over 20 seconds:

Class   0: Current=3, Max=3, Active=0                                   

  Init  1:     45 Events,     4 Jobs                                    

           Highest elapsed time 00.00.20.44 on 00.07.13 JULY 28TH, 2019 

           by Event ESP.START_X114WS, UNCONDITIONAL                 

           Highest CPU     time 00.00.00.04 on 00.07.13 JULY 28TH, 2019 

           by Event ESP.START_X114WS, UNCONDITIONAL          

.......

You can increase the MPL to have more concurrent processes in ESP, and/or reduce the MPL for the EICLASS that can endure more delay:

OPER EICLASS SET CLASS(0) MPL(10)

OPER EICLASS SET CLASS(9) MPL(2)

Note: this means ESP STC CPU usage can spike, even the total CPU usage won't increase.
