* Add dashboard screenshot harness to the dev tooling dashboard-dev-screenshots.py drives headless Chromium (Playwright) against the dashboard dev stack and captures how Kibana, OpenSearch Dashboards, Grafana, and Splunk actually render the current sample data — for end-to-end verification of dashboard changes and PR evidence. It encodes the platform quirks that otherwise cost time to rediscover: fixed render waits instead of networkidle (Kibana/OSD dashboards poll forever), pinning OSD to the global tenant (a stale private-tenant copy silently screenshots old dashboards), and driving the Grafana and Splunk login forms rather than HTTP basic auth. The output directory is gitignored; usage is documented in dashboards/README.md. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Address Copilot review findings on the screenshot harness - Only require OPENSEARCH_INITIAL_ADMIN_PASSWORD / SPLUNK_PASSWORD when the osd / splunk targets are selected, and fail fast before launching Playwright with a clear message naming the missing variable(s). - Honor GRAFANA_USER (defaulting to admin) to match the dev bootstrap script instead of hard-coding the Grafana username. - Print a full traceback to stderr when a target fails, instead of just the exception message, while still continuing to the next target. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Always close the browser when a screenshot target fails Copilot round 2: each target only closed its Chromium instance on the happy path, so a mid-run Playwright failure leaked a headless browser while the script continued to the next target. Wrap each target body in try/finally; closing the browser also closes its contexts and pages, so the single b.close() covers the OSD context too. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Exit with an install hint when playwright is missing Copilot round 3: playwright is deliberately not a project dependency, so a bare import failure produced a raw ModuleNotFoundError traceback. Catch ImportError and exit with the same one-time install command the module docstring documents.

Dashboard development
This directory holds the dashboard sources that ship with parsedmarc:
- opensearch/opensearch_dashboards.ndjson — the source-of-truth saved-objects export. It is imported into both OpenSearch Dashboards and Kibana (the file format is compatible with both).
- grafana/Grafana-DMARC_Reports.json — the Grafana dashboard, with two Elasticsearch datasources (
dmarc-ag,dmarc-fo). - grafana/Grafana-DMARC_Reports-PostgreSQL.json — the Grafana dashboard for the PostgreSQL backend.
- splunk/ — three Splunk dashboard XML views (
dmarc_aggregate,dmarc_failure,smtp_tls).
Edits to any of these files should be exported from a running instance after authoring the change in the UI, not hand-edited (with the occasional exception of small XML tweaks for Splunk).
The dev stack
docker-compose.dashboard-dev.yml brings up every viz target at once so a single dashboard change can be authored and re-exported across all four UIs in one session. It include:s docker-compose.yml for the Elasticsearch and OpenSearch backends, then layers on Kibana, OpenSearch Dashboards, Grafana, and Splunk.
| Service | URL | Credentials |
|---|---|---|
| Elasticsearch | http://localhost:9200 | (security disabled) |
| OpenSearch | https://localhost:9201 | admin / $OPENSEARCH_INITIAL_ADMIN_PASSWORD |
| Kibana | http://localhost:5601 | (security disabled) |
| OpenSearch Dashboards | http://localhost:5602 | admin / $OPENSEARCH_INITIAL_ADMIN_PASSWORD |
| Grafana | http://localhost:3000 | admin / $GRAFANA_PASSWORD |
| Splunk Web / HEC | http://localhost:8000 / https://localhost:8088 | admin / $SPLUNK_PASSWORD, HEC token $SPLUNK_HEC_TOKEN |
All ports bind to 127.0.0.1 only.
Prerequisites
-
Docker with the Compose v2 plugin.
-
A repo-root
.envdefining the secrets the compose file references:OPENSEARCH_INITIAL_ADMIN_PASSWORD=... SPLUNK_PASSWORD=... SPLUNK_HEC_TOKEN=... GRAFANA_PASSWORD=...Pick any values you like — these are local-only dev secrets. Both
.envandparsedmarc*.iniare gitignored. The matching values must also appear in parsedmarc-dev.ini, which the bootstrap script feeds to the parsedmarc CLI for sample-data ingestion. -
The parsedmarc CLI on
PATH(or in./venv/bin/) —pip install -e .[build]from the repo root works. Override the lookup withPARSEDMARC_BIN=/path/to/parsedmarcif needed.
One-shot bootstrap
dashboard-dev-bootstrap.sh is the normal entry point. It is idempotent — re-run it any time:
./dashboard-dev-bootstrap.sh
It does, in order:
docker compose -f docker-compose.dashboard-dev.yml up -dand waits for every service's health endpoint.- Provisions Splunk: creates the
emailindex, creates theDMARCapp, configures the auto-created HEC token to allow theemailindex, and scopes the search-app's "scheduled export" announcement view away fromglobalso it stops appearing in the DMARC app's dashboard list. - Seeds Elasticsearch, OpenSearch, and Splunk with parsedmarc-parsed sample reports (from samples/) so the dashboards render against real data. Skipped when ES already has aggregate docs — pass
RESEED=1to wipe and re-seed all three backends. - Imports the dashboard files from this directory into the running services. This step always runs, so the typical edit loop is edit in the UI → export → save into this directory → re-run the bootstrap script to verify the file imports cleanly into a fresh service.
VS Code users can run this via the Dev Dashboard: Bootstrap task in .vscode/tasks.json. Dev Dashboard: Up brings the stack up without importing or seeding.
Editing a dashboard
After running the bootstrap script once, the round trip for each platform is:
OpenSearch Dashboards (and Kibana)
- Edit the dashboard at http://localhost:5602/ (OpenSearch Dashboards) — this is the canonical authoring surface.
- Stack Management → Saved Objects → Export, select the DMARC dashboard, include related objects, and save the resulting
.ndjsonover opensearch/opensearch_dashboards.ndjson. - Re-run
./dashboard-dev-bootstrap.shto confirm it re-imports cleanly into both OSD and Kibana. The Kibana CI workflow (.github/workflows/dashboards.yml) also imports the same file on every PR that touches it.
OSD imports default to the global_tenant so other admins on the instance can see the result. Set OSD_TENANT=... to import elsewhere.
Grafana
- Edit the dashboard at http://localhost:3000/.
- Dashboard settings → JSON Model, copy the JSON, save it to grafana/Grafana-DMARC_Reports.json.
- Re-run the bootstrap script.
The bootstrap script provisions two elasticsearch datasources (dmarc-ag for dmarc_aggregate*, dmarc-fo for dmarc_f*, which matches both pre-rename dmarc_forensic* and post-rename dmarc_failure*) on first run; existing datasources are left alone.
Splunk
- Edit the dashboard at http://localhost:8000/ inside the DMARC app.
- Open the dashboard's Source view, copy the XML, and paste it over the matching file in splunk/ (
dmarc_aggregate_dashboard.xml,dmarc_failure_dashboard.xml, orsmtp_tls_dashboard.xml). - Re-run the bootstrap script. It re-imports each view via
DELETE+POSTto the splunkd management API.
Screenshotting the dashboards
dashboard-dev-screenshots.py captures how each UI actually renders the current sample data — useful for verifying a dashboard change end-to-end and for PR evidence. One-time setup, then run against the live stack:
pip install playwright && playwright install chromium
set -a; . ./.env; set +a
./dashboard-dev-screenshots.py # all four UIs
./dashboard-dev-screenshots.py grafana # or a subset
Output lands in dashboard-screenshots/ (gitignored). The script encodes
the platform quirks that otherwise cost time to rediscover: Kibana/OSD
dashboards never reach Playwright's "networkidle" (fixed render waits are
used instead), OSD must be pinned to ?security_tenant=global or a stale
private-tenant copy may be captured, and Grafana/Splunk need their login
forms driven rather than HTTP basic auth.
Reseeding sample data
RESEED=1 ./dashboard-dev-bootstrap.sh
Wipes every dmarc_aggregate* / dmarc_failure* / dmarc_forensic* / smtp_tls* index from ES and OS, drops and recreates the Splunk email index, then re-runs the parsedmarc CLI against the curated sample list. Use this after changing parsedmarc's enrichment or output schemas.
Tearing the stack down
docker compose -f docker-compose.dashboard-dev.yml down # stop containers, keep volumes
docker compose -f docker-compose.dashboard-dev.yml down -v # also drop volumes (full reset)
