Refactored the SMTP TLS Splunk dashboard to use a base search for improved query efficiency and maintainability. Updated input token names and adjusted search queries for better organization and clarity.
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). - splunk/ — three Splunk dashboard XML views (
dmarc_aggregate,dmarc_forensic,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.

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_forensic*) 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_forensic_dashboard.xml, orsmtp_tls_dashboard.xml). - Re-run the bootstrap script. It re-imports each view via
DELETE+POSTto the splunkd management API.
Reseeding sample data
RESEED=1 ./dashboard-dev-bootstrap.sh
Wipes every dmarc_aggregate* / 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)
