Overview

In the scope of PERF-524 it's needed to run tests to answer questions:

Can the current System accommodate an average load? Load model described here NLA load model investigation and creation.
- If not PERF-525
What happened at peak times when all workflows are running at once?
Typical KPIs:
- Service CPU
- Service Memory
- DB CPU
- DB Memory
Response times
Duration of long workflows
Recommendations to improve on scaling up/out modules to accommodate peak times

Summary

The current system can accommodate an average load only without Data Import. With data import, we will have 'HTTP 500 Internal Server Error. If the issue persists, please report it to EBSCO Connect.' for several workflows in the source-storage/records/{id}/formatted requests PERF-582 - Getting issue details... STATUS , and the general response time will be longer up to 2 times for all other workflows.
According to the ticket PERF-525 - Getting issue details... STATUS , were performed a set of tests with changing parameters of DI modules. Results in the table show that for the configuration of mod-source-record-manager with 500 database connections count and mod-source-record-storage with 500 database connections count and 60-sec timeout it was not observed "HTTP 500 Internal Server Error." issue, but the response time for requests like GET /source-storage/records/id/formatted greatly increases during DI (up to 75 sec).
Increasing the number of database connections to DB_MAXPOOLSIZE = 200 for mod-source-record-manager and mod-source-record-storage did not give any positive effect on 'HTTP 500 Internal Server Error. If the issue persists, please report it to EBSCO Connect.' but duration of Data Import job was decreased twice.
Service CPU utilization did not exceed 36% even at the beginning of all processes together. Without spikes at the beginning and start of DI jobs average CPU usage was about 15%. Instance CPU Utilization did not exceed 22%.
Service memory utilization was stable, and no memory leaks were suspected during tests.
Each FYR (Fiscal close - end of FY rollover) job is consuming a lot of DB CPU (each spike here corresponds to each FYR job). Approximately DB CPU usage was up to 92%

*Note that workflows that have response times or durations in red are the ones that are at least 2 times higher than when running without Data Import jobs.
*** Test run results with the configuration of mod-source-record-manager with 500 database connections count and mod-source-record-storage with 500 database connections count and 60-sec timeout.

Throughput graphs

For Test#1, Test#3 and Test#4 graphs are almost the same.

Memory Utilization

Memory utilization of the most memory-consuming modules & DI modules:

mod-inventory - 98%
mod-orders - 73%
mod-source-record-manager - 44%
mod-source-record-storage - 23,5%
mod-inventory-storage - 31%
data-import - 22%
mod-di-converter-storage - 31%

This graph represents memory usage of 3 first test runs and shows that no memory leak is suspected for all of the modules.

Service CPU Utilization

CPU usage did not exceed 36 % for all modules. We can observe spikes in CPU usage of DI modules at the beginning of the Data Import jobs. Without DI spikes average CPU usage was about 15%.

Test# 1 - Test# 4 DI duration - 17 min.
Test# 5 DI duration - 8 min.

Most CPU-consuming modules:

mod-inventory - 36%
mod-authtoken -25%
mod-data-import - 16%
mod-di-converter-storage -15,6%
mod-quick-marc - 15%
mod-finance-storage - 14%
nginx-okapi - 14%
okapi - 11%
mod-tags -10,6%
others - usage less than 10%
mod-source-record-manager - up to 7%
mod-source-record-storage - up to 4%

Instance CPU Utilization

RDS CPU Utilization

Each FYR (Fiscal close - end of FY rollover) job is consuming a lot of DB CPU (each spike here corresponds to each FYR job).

Approximately DB CPU usage is up to 92%

RDS Database Connections
Test# 1 - Test# 4 for part of the test with DI job- 620 connections count.
Test# 5 for part of the test with DI job- 820 connections count. (allocated additional 200 connections for DI modules)

Methodology/Approach

To test Baseline for normal NLA library usage the JMeter scripts were used.

Tested with different DI delays:

From test start
1 min delay
20 min delay
without DI

Data was gathered from 2 periods with and without data import.

DI - data import
FYR - Fiscal close - end of FY rollover
