OpenHIM Platform performance testing #321
Conversation
WalkthroughThe recent changes introduce a comprehensive suite of K6 performance testing scripts and a new Grafana dashboard for monitoring application performance. Enhancements include various testing scenarios—smoke, volume, load, stress, and soak tests—alongside a script for generating healthcare data in JSON format. Additionally, detailed README files provide essential guidelines for conducting performance tests, ensuring users can thoroughly evaluate their systems under realistic conditions. Changes

28-44: EnsuregenerateBundleproduces valid data.The
generateBundlefunction is used to generate data for the POST request. Verify that it produces valid and expected data for the FHIR endpoint.Verification successful
generateBundleProduces Valid FHIR DataThe
generateBundlefunction is defined intest/performance/resources/ips-bundle-transaction.js. It constructs a JSON string by replacing placeholders with dynamically generated data using thefakerlibrary. This includes UUIDs, names, dates, and other identifiers, ensuring the data is randomized and unique for each call. The final JSON string is parsed and returned as a JavaScript object, which should be valid for the FHIR endpoint as it adheres to expected data structures.
- File:
test/performance/resources/ips-bundle-transaction.js- Lines: 12-356
The function appears to be correctly generating valid data for the FHIR endpoint. No further issues were found with the implementation.
Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash # Description: Verify the output of `generateBundle` function. # Test: Log the output of `generateBundle` to ensure it is valid. ast-grep --lang javascript --pattern 'function generateBundle() { $$$ }' --json | jq '.[0].content' | node -e "console.log(eval(require('fs').readFileSync('/dev/stdin', 'utf8'))())"Length of output: 273

test/performance/scripts/volume.js (2)
7-30: Review the volume test configuration.The volume test is configured with a ramping arrival rate. Ensure this configuration aligns with your testing goals and infrastructure capacity.
32-48: EnsuregenerateBundleproduces valid data.The
generateBundlefunction is used to generate data for the POST request. Verify that it produces valid and expected data for the FHIR endpoint.Verification successful
The
generateBundlefunction appears to produce valid data for FHIR testing.The
generateBundlefunction generates a JSON object by replacing placeholders with realistic data using thefakerlibrary. This includes UUIDs, names, dates, and other identifiers, which are essential for simulating FHIR bundle data. The function seems well-suited for generating test data for FHIR endpoints.
- The function reads a JSON template from
ips-bundle-transaction.json.- It uses
fakerto generate realistic data for various fields like UUIDs, names, and dates.- The placeholders in the JSON are replaced with these generated values using
replacePlaceholder.Given this setup, the function should produce valid and expected data for the FHIR endpoint.

8-32: Review K6 options configuration.The K6 options are configured for a stress test scenario using
ramping-arrival-rate. Ensure that the stages and thresholds are appropriate for the intended stress testing goals.
34-50: Ensure thegenerateBundlefunction is correctly implemented.The
generateBundlefunction is used to create data for the POST request. Verify that this function generates the expected data structure.Verification successful
The
generateBundlefunction is correctly implemented. The function generates a JSON object with various fields populated by dynamically generated values using thefakerlibrary, suitable for testing purposes.Scripts executed
The following scripts were executed for the analysis:

4-4: Consider making theBASE_URLconfigurable.The
BASE_URLis set to a default value ofhttp://localhost:5001. Ensure that this environment variable is set correctly in different environments.Verification successful
Ensure
BASE_URLis set in deployment environmentsThe code already supports configuring
BASE_URLvia an environment variable, defaulting tohttp://localhost:5001if not set. This aligns with the review comment's suggestion. Ensure that deployment environments set this variable appropriately to avoid using the default value unintentionally.Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash # Verify if BASE_URL is set in the environment if [ -z "$BASE_URL" ]; then echo "BASE_URL is not set. Using default: http://localhost:5001" else echo "BASE_URL is set to: $BASE_URL" fiLength of output: 140
test/performance/resources/ips-bundle-transaction.js (1)
358-361: Check thereplacePlaceholderfunction.The
replacePlaceholderfunction uses a regular expression to replace placeholders in a JSON string. Ensure that the function works as intended and handles edge cases.test/performance/resources/ips-bundle-transaction.json (5)
3-11: Ensure uniqueness of identifiers.The
idandidentifierfields use placeholders like{{bundleUUID}}and{{bundleIdentifierUUID}}. Ensure that these values are unique across different bundles to prevent data conflicts.
35-47: Check for duplicate identifiers.The
identifierarray contains multiple entries with similar types, such asPHN,PPN,DL, etc. Ensure that these identifiers are unique within thePatientresource to avoid data integrity issues.
175-176: Verify placeholder values.Ensure that placeholders like
{{patientGender}}and{{patientDOB}}are replaced with valid values during data generation, as these fields are critical for patient data accuracy.
373-422: Validate AllergyIntolerance resource.Check that the
AllergyIntoleranceresource includes all necessary fields, such asclinicalStatus,verificationStatus,type,code, andpatient. Ensure that placeholders are correctly replaced with valid data.
901-936: Ensure correct URL structure.The
fullUrlfields use a base URL likehttp://hapi-fhir:8080/fhir/. Confirm that this URL is correct and accessible in the testing environment to ensure successful data transactions.monitoring/grafana/dashboards/performance/k6.json (3)
4-10: Verify Prometheus data source configuration.Ensure that the Prometheus data source (
DS_PROMETHEUS) is correctly configured and accessible from Grafana to avoid issues with data visualization.
266-329: Review PromQL expressions for accuracy.The PromQL expressions used in the targets should be verified to ensure they accurately capture the intended metrics. For example, ensure that the expressions for
k6_vus,k6_http_req_duration, andk6_http_reqs_totalare correct and return the expected data.
542-709: Check panel configurations for completeness.Ensure that all panels are configured with the necessary options, such as legend settings and tooltip modes, to provide clear and informative visualizations.

In addition I'd like you to include the results of a run to give an indication of the current capabilities of platform. This should include the system tested on and the results achieved.

Do we have a guides section? Also should we provide only sample results for a specific performance test?
There was a problem hiding this comment.
I think we need both. A guide on how to reproduce and the an example run using specific hardware to give people an idea of the current performance. So both.
The guides section is here: https://github.com/jembi/platform/tree/main/documentation/guides
