Overview

• This document contains the results of testing MOBIUS master-script tests on the MCPT environment with different environment configurations.

PERF-942 - Getting issue details... STATUS  

Summary

• During the Data-Export tests we observe Error "java.lang.OutOfMemoryError: Metaspace", so parameters for data-export module were changed:
  
  • "memory": 1024 → 2304
  • "memoryReservation": 896 → 2048
  • -XX:MaxMetaspaceSize=128m → 256m
  • -Xmx768m → 1536m
• After upgrade Data-Export module all Data Export tests finished successfully on qcpt environment using the Default instances, authority, holdings export job profiles and Custom PTF Profiles.

• No memory leaks, memory consumption was stable during all of the tests.

• Database CPU usage varied up to a maximum of 26%

Methodology/Approach

MOBIUS Tests: scenarios were started by JMeter script from load generator. We had 100% error count for AIE_TC: Create Invoices, AIE_TC: Invoices Approve, AIE_TC: Paying Invoices, TC: Receiving-an-Order-Line, Unreceiving-a-Piece and Unreceiving-a-Piece Workflows because data was not regenerated.  

• Test 1: Baseline MCPT Environment configuration according to tunning environment from previous report:  task count: 4 for services: mod-permissions, mod-search, mod-patron, mod-inventory, mod-inventory-storage, mod-circulation, mod-circulation-storage, mod-order, mod-order-storage, mod-invoice, mod-invoice-storage, for mod-users and mod-authtoken task count 6. Parameter srs.marcIndexers.delete.interval.seconds=86400 for mod-source-record-storage. Instances count: 14. Database r6g.4xlarge, Amazon OpenSearch Service  ptf-test: r6g.2хlarge.search (4 nodes).
• Test 2: The Baseline MCPT Environment configuration was applied, and CPU=0 was set for all modules.
• Test 3: The Baseline MCPT Environment configuration was applied, the instance type was changed to x2gd.xlarge, the number of instances was changed to 6, and CPU=0 was set for all services.
• Test 4: The Baseline MCPT Environment configuration was applied, the instance type was changed to x2gd.xlarge, the number of instances was changed to 8, and CPU=0 was set for all services.
• Test 5: The Baseline MCPT Environment configuration was applied, the instance type was changed to x2gd.large, the number of instances was changed to 10, and CPU=0 was set for all services.
• Test 6: The Baseline MCPT Environment configuration was applied, the instance type was changed to r6g.xlarge, the number of instances was changed to 14 but 12 were used, and CPU=2 was set for all services.
• Test 7: The Baseline MCPT Environment configuration was applied, the instance type was changed to r6g.xlarge, the number of instances was changed to 14, placement strategy was updated to "one task per host", and CPU=2 was set for all services.
• Test 8: The Baseline MCPT Environment configuration was applied, the instance type was changed to x2gd.large, the number of instances was changed to 14, placement strategy was updated to "one task per host", and CPU=2 was set for all services.
