From Installation to Insights: Getting Started with SQL Server SurveyorIntroduction

SQL Server Surveyor gathers inventory, configuration, performance metrics, and security posture across SQL Server instances to help DBAs, security teams, and IT managers understand what they have and where to focus. This guide walks through installation, initial configuration, core features, common workflows, and practical tips to turn raw discovery into actionable insights.

What SQL Server Surveyor Does (Overview)

SQL Server Surveyor is a discovery and assessment solution focused on SQL Server environments. Typical capabilities include:

  • Automated instance discovery across networks and cloud regions.
  • Inventory of databases, logins, jobs, and linked servers.
  • Configuration auditing (e.g., trace flags, max server memory, authentication modes).
  • Security posture assessments (vulnerable permissions, exposed credentials, misconfigured service accounts).
  • Performance snapshotting (wait stats, index usage, query plans) and historical trends.
  • Compliance reporting for standards like CIS, PCI, GDPR.
  • Integrations with monitoring, SIEMs, CMDBs, and ticketing systems.

Pre-installation Planning

  1. Environment inventory and scope

    • Decide which servers, instances, and cloud subscriptions to include. Include standalone instances, failover clusters, and managed services (Azure SQL, Amazon RDS/Aurora) if supported.

  2. Access & credentials

    • Choose an account for discovery: a low-privilege read-only account is preferable for security, but some checks require higher privileges (server-level DMVs, extended stored procedures, CLR). Plan for credential vaulting if available.

  3. Network & firewall considerations

    • Ensure TCP access to SQL Server ports (default 1433) and any management/service endpoints for the Surveyor. Account for jump boxes and bastion hosts in segmented networks.

  4. Storage & retention

    • Determine where inventory and telemetry will be stored, retention periods for historical metrics, and disk/DB sizing requirements.

  5. Integration plan

    • Identify SIEM, monitoring, and ticketing integrations. Plan authentication (API keys, service accounts) and mapping rules (hostnames, tags).

Installation Steps (Typical)

Note: exact steps vary by vendor and version. The sequence below is a generic template.

  1. Download installer or deploy container/VM image

    • Obtain the Surveyor package from the vendor or marketplace.

  2. Install prerequisites

    • .NET runtimes, Python, or database client libraries as specified. Confirm OS versions and patches.

  3. Create and configure backend storage

    • Provision the repository database (often SQL Server or PostgreSQL). Run any schema migrations or initialization scripts.

  4. Install Surveyor server and services

    • Run the installer or deploy the container. Configure service accounts and start services.

  5. Configure web UI and API endpoints

    • Set up TLS, bind hostnames, and configure external access. Harden default admin accounts.

  6. Add credential store (optional but recommended)

    • Configure a secure vault for discovery credentials (Azure Key Vault, HashiCorp Vault, or built-in vault).

  7. Deploy collectors/agents (if required)

    • Agents capture metrics from remote networks or isolated environments. Install these on designated hosts and register them with the central server.

  8. Initial discovery run

    • Add target ranges, host lists, or cloud credentials and run the first discovery. Review logs for connectivity or permission errors.

Initial Configuration and Tuning

  • Baseline settings: set the frequency of scans (daily/weekly), performance telemetry intervals (1–15 minutes), and sampling windows for historical aggregation.
  • Alerting: configure thresholds for critical items (failed jobs, full transaction logs, CPU/IO hotspots). Use severity levels and channel mappings (email, Slack, PagerDuty).
  • User roles and RBAC: create roles (viewer, analyst, admin) and limit access to sensitive credential and configuration areas.
  • Tagging and grouping: apply tags to instances by environment (prod, stage, dev), business unit, or application to simplify filtering and reports.
  • Data retention: choose retention windows that balance investigative needs and storage costs; keep higher-resolution recent data and aggregated historical data.

Core Features and How to Use Them

Discovery & Inventory

  • Run network scans and cloud connectors to build an inventory. Validate discovered instance names, versions, and cluster roles.
  • Use inventory reports to identify unsupported SQL Server versions, orphaned databases, or undocumented instances.

Configuration Audit

  • Compare instance settings against recommended baselines (CIS benchmarks, vendor best practices).
  • Prioritize misconfigurations by risk: things that allow remote admin access, weak authentication settings, or disabled auditing should be high priority.

Security Assessment

  • Identify high-risk accounts (sysadmin role assignments, logins with dbo ownership, shared sa usage).
  • Detect exposed credentials in jobs, linked servers, or configuration files.
  • Produce compliance-ready reports and evidence for auditors (snapshots of permissions and configuration at a point-in-time).
  • Capture wait stats, top resource-consuming queries, and index usage.
  • Use historical trends to find slow configuration changes, gradual index fragmentation, or recurring maintenance gaps.
  • Correlate performance spikes with deployment or maintenance events using tagging and timestamps.

Query/Index Recommendations

  • Review recommended index changes and missing index suggestions, but validate before applying: consider write overhead, duplicate indexes, and overall schema/design.
  • Use a staging area for recommendations to simulate impact or test on a subset of instances.

Reporting & Dashboards

  • Build dashboards for executive views (inventory counts, risk posture) and operational views (health, alerts).
  • Schedule automated reports for stakeholders: weekly health digests, monthly compliance snapshots, and pre-change checklists.

Common Workflows (Practical Examples)

  1. New environment onboarding

    • Run discovery, tag production servers, run an initial security and configuration audit, and schedule weekly telemetry. Share baseline reports with application owners.

  2. Monthly security review

    • Generate a permissions report, identify new high-privilege accounts, check for disabled auditing, and create remediation tickets for high-risk items.

  3. Performance troubleshooting

    • Use recent performance snapshots to identify top waits and queries. Cross-check index recommendations and recent deployments to find root causes.

  4. Compliance audit support

    • Export point-in-time evidence: configuration snapshots, login assignments, and audit settings. Produce a compliance narrative linking findings to remediation steps.

Best Practices & Operational Tips

  • Use least-privilege discovery accounts; only escalate where necessary.
  • Schedule heavy discovery or deep configuration scans during maintenance windows for busy systems.
  • Keep Surveyor components patched and monitor its own health.
  • Validate automations: auto-remediation should be conservative and reversible.
  • Maintain a change log for when configuration baselines or alert thresholds change.
  • Combine Surveyor outputs with APM and OS-level metrics for full-stack correlation.

Troubleshooting Common Issues

  • Connection failures: verify network routes, SQL service status, and credentials. Check for named instances using dynamic ports.
  • Incomplete discovery: confirm permissions for server-level DMVs and WMI/PowerShell access for OS-level data.
  • High storage growth: reduce telemetry retention or increase aggregation granularity for older data.
  • False positives in security checks: review context—some permissions may be necessary for legacy apps; document exceptions.

Example: Quick Checklist for First 30 Days

  1. Install Surveyor and connect to a secure credential vault.
  2. Discover all production instances and tag them.
  3. Run configuration and security audits; file tickets for critical risks.
  4. Configure key alerts (jobs, backups, disk space, CPU/IO) and route them to on-call.
  5. Build a basic dashboard for operations and a compliance snapshot for auditors.
  6. Review index recommendations and plan validations in test environments.

Measuring Value: KPIs to Track

  • Number of discovered instances vs. known inventory.
  • Time to detect and remediate critical security findings.
  • Reduction in unplanned downtime attributable to Surveyor alerts.
  • Number of risky permissions removed or hardened.
  • Performance improvements after applied recommendations (e.g., average query latency).

Conclusion

Deploying SQL Server Surveyor turns scattered knowledge about SQL Server instances into centralized inventory, security posture awareness, and performance insights. Start with careful planning—credentials, scope, and storage—and iterate: tune discovery frequency, alert thresholds, and report cadence to match operational rhythms. Treat Surveyor as a continuous assessor that helps reduce risk, improve performance, and support compliance rather than a one-time setup.
