  • Test Run 1: Running without New Relic.

  • Test Run 2: Running with the New Relic monitoring tool enabled.

  • Test Run 3: Running with the New Relic monitoring tool enabled and changed JVM mod-oa parameter from -XX:MaxMetaspaceSize=128m to -XX:MaxMetaspaceSize=256m

These tests were performed using 20 virtual users to simulate the load on the system. The environment was used for these tests QCP1.

The primary goal of these tests is to assess whether the New Relic monitoring tool impacts the system’s performance.

Summary

Test Run 1 (Without New Relic). Generate 3159 Check-out transactions and 2420 Check-in transactions. The error rate during the test was 0.04 %. Median Response time for CO = 1.585 960 seconds and median Response time for CI = 1.214 640 seconds.

Test Run 2 (With New Relic). Generate 3180 Check-out transactions and 2381 Check-in transactions. The error rate during the test was 0.04 %. Median Response time for CO = 1.594 968 seconds and median Response time for CI = 1,193 seconds.
Conclusion. Two 594 seconds.
Test Run 3 (With New Relic + mod-oa(256m)). Generate 3212 Check-out transactions and 2402 Check-in transactions. The error rate during the test was 0.04 %. Median Response time for CO = 948 seconds and median Response time for CI = 588 seconds.

Conclusion. Two separate tests were conducted in order to determine the impact of enabling New Relic monitoring tool on the Check-in/Check-Out process. The aim of the test was to identify any significant variations in key performance metrics that could potentially be attributed to New Relic.

...

In conclusion, the results of the tests demonstrate that utilizing the New Relic monitoring tool does not adversely affect the check-in/check-out process and the overall system performance remains unaffected.

...

, but after deployment of New RElic we observed high CPU consumption and OOM errors on mod-oa service.

  1. After increasing mod-oa parameter from -XX:MaxMetaspaceSize=128m to -XX:MaxMetaspaceSize=256m memory CPU utilization decrease to 80%.

Recommendations & Jiras (Optional)

  • While the current tests provided insights into how New Relic impacts the CICO process, it's recommended for future analysis to cover a more extensive range of operations to fully evaluate the impact of New Relic on the system performance during data-import, data-export, or other workflows.

  • Investigate errors described in the Error section, high CPU consumption and OutOfMemoryError on mod-oa module
