Collibra is the enterprise data intelligence platform that serves as the authoritative system of record for data governance across large organizations — providing data catalog, business glossary, lineage tracking, policy management, data quality workflows, and stewardship processes that let data teams govern their assets across every warehouse, lake, and application in the enterprise. When the Collibra platform becomes unavailable, data stewards cannot manage certification workflows, policy owners cannot update governance rules, and compliance teams lose access to the audit trails that regulatory reviews depend on. When the Collibra REST API degrades, the downstream integrations that push lineage from dbt, pull certification status for pipeline gating, and sync business glossary terms to downstream BI tools all begin to fail silently. When the workflow engine stops processing, governance approval chains stall — data assets sit in limbo waiting for steward review while analysts are blocked from promoting data to certified status. Vigilmon gives you external visibility into Collibra's critical infrastructure: the web application, REST API, and workflow engine endpoints, so you know the moment the enterprise data governance platform itself needs attention.
What You'll Build
- An HTTP monitor on the Collibra platform application to detect availability failures
- A health-check monitor on the Collibra REST API to catch backend degradation
- A monitor on the Collibra workflow engine to detect stalled governance approval pipelines
- A monitor on your webhook receiver to verify Collibra event delivery is flowing
- An SSL certificate monitor for your Collibra domain
- Alerting that distinguishes application outages from API degradation and workflow engine failures
Prerequisites
- A Collibra deployment (Collibra Cloud or self-managed on-premises instance)
- The Collibra platform accessible via HTTPS
- A webhook receiver endpoint configured to accept Collibra governance event notifications
- A free account at vigilmon.online
Step 1: Understand Collibra's Service Architecture
Collibra is a multi-component enterprise platform where each component has distinct availability requirements and failure modes:
| Component | Default port | Role |
|---|---|---|
| Collibra DGC application | 443 (HTTPS) | Web UI for catalog browsing, lineage visualization, governance workflows, and stewardship |
| REST API (Collibra Core API) | 443 (HTTPS) | Programmatic access to assets, communities, domains, workflows, and governance metadata |
| Workflow engine | Internal | Processes stewardship approval chains, certification requests, and policy review cycles |
| Integration service | Internal/outbound | Syncs metadata between Collibra and connected data sources, BI tools, and cloud warehouses |
| Event dispatcher | Outbound | Delivers governance event notifications to subscribed webhook endpoints and integrations |
External monitoring focuses on the application, REST API, and workflow engine — these are the surfaces your data stewards, governance teams, compliance analysts, and pipeline integrations touch every day. Workflow engine failures are the hardest to detect without active monitoring because governance tasks simply stop progressing rather than returning visible errors to end users.
Step 2: Monitor the Collibra Platform Application
The Collibra web application is the primary interface for every governance workflow: browsing the business glossary, reviewing data lineage graphs, managing certification and deprecation processes, applying data policies, and coordinating stewardship assignments across communities and domains:
curl -I https://your-collibra-instance.collibra.com
# Returns HTTP 200 with HTML when the platform is healthy
- Log in to Vigilmon → Add Monitor → HTTP.
- URL:
https://your-collibra-instance.collibra.com(your Collibra Cloud or on-premises URL). - Check interval: 60 seconds.
- Response timeout: 15 seconds.
- Expected status:
200. - Keyword:
Collibra(present in the page title and application HTML). - Click Save.
This monitor catches:
- Collibra application server failures or cloud infrastructure outages
- Failed Collibra upgrades or patch deployments that leave the platform returning 5xx errors
- Load balancer or reverse proxy misconfigurations that block traffic to the Collibra application
- DNS resolution failures for the Collibra hostname
Alert sensitivity: Set to trigger after 1 consecutive failure. When Collibra is unavailable, compliance teams lose access to audit trails they may need for regulatory reviews, data stewards cannot process certification workflows, and the authoritative business glossary that downstream BI tools and data consumers rely on becomes inaccessible.
Step 3: Monitor the Collibra REST API
The Collibra Core REST API is the backbone of every programmatic integration in the governance ecosystem — dbt pushes column-level lineage to Collibra, Tableau reads certification status before displaying a dataset, custom governance bots query workflow status, and enterprise identity systems sync user and role assignments. When the API degrades, these integrations fail in ways that do not surface as obvious application errors:
curl https://your-collibra-instance.collibra.com/rest/2.0/ping
# Returns: {"status": "online"} when the API backend is operational
- Add Monitor → HTTP.
- URL:
https://your-collibra-instance.collibra.com/rest/2.0/ping. - Check interval: 60 seconds.
- Response timeout: 10 seconds.
- Expected status:
200. - Keyword:
online(present in healthy API ping responses). - Label:
Collibra REST API. - Click Save.
Why monitor the API separately from the application UI? Collibra's web application may serve cached views from the frontend even when the API backend is under load or partially unavailable. A failing REST API means lineage pushes from dbt and Spark jobs queue up indefinitely, certification status queries from downstream data products return stale or empty responses, and the data mesh policies that depend on Collibra as the policy authority cannot retrieve valid governance decisions.
Step 4: Monitor the Collibra Workflow Engine
Collibra's workflow engine is the component that drives all governance automation — routing certification requests to the correct steward, escalating overdue approvals, enforcing policy review cycles, and triggering downstream actions when a governance decision is finalized. Unlike the application and API, workflow engine failures do not produce HTTP errors visible from outside the platform:
curl https://your-collibra-instance.collibra.com/rest/2.0/workflows/instances?limit=1
# Returns workflow instance list when the engine is processing normally
- Add Monitor → HTTP.
- URL:
https://your-collibra-instance.collibra.com/rest/2.0/workflows/instances?limit=1. - Check interval: 2 minutes.
- Response timeout: 15 seconds.
- Expected status:
200. - Keyword:
total(present in paginated workflow response JSON). - Label:
Collibra workflow engine. - Click Save.
Why workflow engine monitoring matters: In mature Collibra deployments, dozens or hundreds of governance approval chains may be active simultaneously. A workflow engine failure that stalls all in-flight processes is invisible to monitors that only check the application health endpoint — stewards receive no notifications, certification requests never progress, and the governance layer appears functional from the outside while all automation is silently frozen.
Step 5: Monitor Your Webhook Receiver
Collibra delivers governance event notifications — asset state changes, certification completions, policy violations, workflow completions — to external systems via webhook subscriptions. If your webhook receiver becomes unavailable, governance event delivery fails silently: downstream systems that depend on Collibra certification events to gate pipeline promotions stop receiving signals, and compliance audit systems that record governance decisions miss events that are difficult to reconstruct retrospectively:
curl https://your-webhook-receiver.example.com/health
# Returns: {"status": "ok"} when the receiver is up
- Add Monitor → HTTP.
- URL:
https://your-webhook-receiver.example.com/health. - Check interval: 2 minutes.
- Response timeout: 10 seconds.
- Expected status:
200. - Keyword:
ok. - Label:
Collibra webhook receiver. - Click Save.
For Slack integrations that route Collibra governance notifications to stewardship channels, verify https://slack.com/api/api.test to confirm the Slack API is reachable. For Collibra deployments that integrate with ServiceNow or Jira for governance issue escalation, monitor those services' health endpoints as well to ensure the full governance notification chain remains intact.
Step 6: Monitor SSL Certificates
Collibra's application and REST API are accessed over HTTPS by data stewards, governance analysts, automated connector jobs, and compliance review tools. An expired certificate blocks browser access to the platform UI, breaks automated lineage sync jobs that connect to the Collibra API over TLS, and causes integration services to fail with certificate verification errors that may not be surfaced clearly to the data platform team:
openssl s_client -connect your-collibra-instance.collibra.com:443 2>/dev/null | openssl x509 -noout -dates
- Add Monitor → SSL Certificate.
- Domain:
your-collibra-instance.collibra.com. - Alert when expiry is within: 30 days.
- Alert again: 14 days, 7 days, 3 days, 1 day.
- Click Save.
On-premises deployment consideration: For Collibra deployments hosted in a customer-managed data center or private cloud, TLS certificates are owned by the customer's infrastructure team, not by Collibra. Vigilmon's 30-day pre-expiry alert is especially valuable for on-premises deployments where certificate renewal requires coordination across the governance platform team, network security, and the PKI team — a window that is easy to miss without proactive monitoring.
Step 7: Configure Alerting
In Vigilmon under Settings → Notifications, configure your alert channels:
| Monitor | Trigger | Action |
|---|---|---|
| Platform application | Non-200 or Collibra missing | Check application server and load balancer; review Collibra Cloud status |
| REST API | Non-200 or online missing | API down; lineage sync, certification queries, and integrations failing |
| Workflow engine | Non-200 or total missing | Governance automation stalled; steward approvals and certification workflows frozen |
| Webhook receiver | Non-200 or ok missing | Governance event delivery broken; verify receiver deployment |
| SSL certificate | < 30 days to expiry | Renew certificate; coordinate with infra team for on-premises deployments |
Alert after: 1 consecutive failure for the application, API, and workflow engine monitors. 2 consecutive failures for the webhook receiver to reduce noise from brief transient timeouts.

Monitoring Data Governance Quality Itself (Beyond Infrastructure)
Vigilmon monitors Collibra's infrastructure endpoints — the platform application, REST API, workflow engine, and your webhook receiver. The quality of governance coverage, policy completeness, and metadata accuracy within Collibra is a separate concern managed through Collibra's own governance processes:
- Collibra's governance workflows: Configure stewardship assignments, certification review cycles, and policy refresh processes within Collibra to ensure governance coverage improves continuously — this is distinct from monitoring Collibra's own platform availability.
- Workflow SLA monitoring: Use Collibra's built-in reporting to track how long certification and approval workflows take to complete. Stalled workflows that have not timed out will not be caught by infrastructure monitoring alone.
- Connector freshness audits: Regularly audit the health of Collibra's metadata connectors to ensure that schema changes in production warehouses are reflected in the catalog and that lineage graphs remain accurate as pipelines evolve.
Vigilmon catches infrastructure-level failures — when Collibra itself is down, its API is degraded, or its workflow engine has stopped processing. Governance quality improvements, policy coverage expansion, and metadata accuracy within a healthy Collibra deployment require Collibra's own governance workflows and stewardship processes.
Collibra is the authoritative system of record for enterprise data governance — when the platform goes down, stewards cannot certify data, compliance teams lose audit access, and the governance layer that enterprise data mesh and regulatory compliance depend on becomes unavailable. Vigilmon gives you external visibility into Collibra's availability that doesn't depend on Collibra self-reporting: application uptime, API health, workflow engine status, and SSL certificate validity, so you know the moment the enterprise governance platform needs attention and can restore stewardship operations before compliance commitments are at risk.
