Overview

The task at hand involves conducting performance tests on Check-in/Check-Out operations under two different conditions:

Test Run 1: Running without New Relic.
Test Run 2: Running with the New Relic monitoring tool enabled.

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.
Ticket: PERF-920 - Getting issue details... STATUS

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 seconds and median Response time for CI = 1.214 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 seconds and median Response time for CI = 1,193 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.

Comparative analysis of the key performance metrics obtained from both tests yielded the following insights:

Response Times: The median and 95th percentile values for response times exhibited similar trends across both test runs, indicating that New Relic did not add any noticeable overhead to the response times.
Error Rate: The error rates remained consistent in both test scenarios. This suggests that the integration of New Relic did not compromise the stability of the Check-in/Check-Out process.
CPU Usage: The slight variation in CPU usage within the tolerance limit of 5% between the test runs poses no significant concern and is well within acceptable boundaries.
Memory Usage: No changes in memory usage patterns were observed upon enabling New Relic, implying the tool has minimal if any, impact on the memory resources of the system.

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.

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

Test Runs

Test Run 1: Running without New Relic.
- Test setup: 20 Virtual users, 4000 seconds, 200 seconds of rump up period.
Test Run 2: Running with the New Relic monitoring tool enabled.
- Test setup: 20 Virtual users, 4000 seconds, 200 seconds of rump up period

Errors

After the deployment of New Relic on QCP1, two services were identified as having high CPU consumption: mod-oa-b and mod-data-export. These two services had new task definitions with new relic variables.

mod-oa was throwing error messages “OutOfMemoryError“

Methodology/Approach

Step 1. Test Run 1 was executed from the carrier box with parameters described in the TEST RUN section.
Step 2. Deploy New Relic, and verify if it works.
Step 3. Test Run 2 was executed from the carrier box with parameters described in the TEST RUN section, with the same parameters as on the step 1.

Test New Relic impact on FOLIO
