1. Quick diagnostic checklist
Before deep-diving, run this short checklist to collect useful information:
- Confirm ADS-Viewer version and operating system.
- Reproduce the issue and note exact steps, error messages, and timestamps.
- Check logs (application logs, system logs) and capture screenshots or screen recordings.
- Test with a minimal dataset or default workspace to rule out user-specific configs.
- Try restarting ADS-Viewer and the host machine.
Collecting these details saves time and often leads to immediate insights.
2. Installation and startup problems
Symptoms:
- Installer fails or crashes.
- ADS-Viewer won’t launch.
- Missing dependencies or runtime errors at startup.
Common causes:
- Corrupt installer or interrupted download.
- Unsupported OS version or missing runtime (e.g., specific .NET, Java, or system libraries).
- Insufficient permissions or antivirus blocking installation.
Fixes:
- Re-download the installer from the official source and verify checksums if available.
- Ensure system meets minimum requirements and install required runtimes/frameworks.
- Run the installer as administrator (Windows) or use sudo (macOS/Linux) when needed.
- Temporarily disable antivirus/firewall during installation; re-enable and add ADS-Viewer to allowlist afterwards.
- Check environment variables (PATH, JAVA_HOME) if ADS-Viewer depends on external runtimes.
- If startup logs show library load errors, reinstall the runtime (e.g., .NET/Java) matching the version ADS-Viewer expects.
Pro tip: If an older version previously worked, check release notes for breaking changes in dependencies.
3. Connectivity and data source errors
Symptoms:
- ADS-Viewer cannot connect to data sources (databases, telemetry servers, REST APIs).
- Authentication failures or timeouts.
- Partial or inconsistent data loads.
Common causes:
- Incorrect connection strings, credentials, or network endpoints.
- Network issues (firewall, VPN, proxy) blocking traffic.
- Schema changes or incompatible data formats.
- Expired tokens or authentication method changes (OAuth, API keys).
Fixes:
- Verify connection strings, ports, and hostnames. Test connectivity with external tools (ping, telnet, curl).
- Confirm credentials and renew tokens or reset API keys as required.
- If behind a proxy or corporate network, configure ADS-Viewer proxy settings or system proxy correctly.
- Check for TLS/SSL certificate errors — import required CA certificates or update the system trust store.
- Validate data format and schema; use a minimal query to confirm basic access before running complex visualizations.
- For intermittent timeouts, increase connection/timeouts in ADS-Viewer settings and examine network latency.
Example: For a REST API with 401 errors, confirm the request headers include a valid Authorization token and that the token scope covers the requested resource.
4. Rendering and visualization issues
Symptoms:
- Charts don’t render or display placeholder/blank panels.
- Visual artifacts, misaligned labels, or incorrect scaling.
- Missing fonts or garbled text.
Common causes:
- Incompatible GPU drivers or hardware acceleration bugs.
- Corrupted configuration or workspace files.
- Data inconsistencies (NaN, nulls) causing rendering exceptions.
- Custom themes or CSS interfering with UI layout.
Fixes:
- Toggle hardware acceleration: try disabling GPU rendering in ADS-Viewer preferences to see if the problem resolves.
- Reset the workspace or create a new one to rule out corrupted layout files.
- Clean data inputs — handle null/NaN values and enforce numeric types before visualization.
- Reinstall or update GPU drivers (NVIDIA/AMD/Intel) and check OS updates for known UI fixes.
- Revert to default theme or remove custom CSS/plugins that alter layout.
- If labels overlap, adjust chart margins, font sizes, or enable label auto-rotation.
Quick debug step: Open developer console (if available) to inspect rendering errors or exceptions.
5. Performance and responsiveness
Symptoms:
- ADS-Viewer becomes slow, laggy, or unresponsive with large datasets.
- High CPU, memory, or GPU usage.
- Long load times for dashboards or complex visualizations.
Common causes:
- Very large datasets loaded into memory.
- Inefficient queries or lack of server-side pagination/aggregation.
- Memory leaks in long-running sessions or plugins.
- Excessive number of visual components on a single dashboard.
Fixes:
- Use sampling, aggregation, or server-side filtering to reduce client-side load.
- Implement pagination or data chunking; request only the fields needed for a visualization.
- Increase system memory or run ADS-Viewer on a machine with more resources for heavy workloads.
- Close unused dashboards and restart the application periodically to free memory.
- Profile queries — add indexes or optimize database queries feeding ADS-Viewer.
- Disable or remove poorly performing plugins; update to versions that fix memory leaks.
Example optimization: Replace SELECT * queries with explicit columns and aggregate on the server: SELECT date_trunc(‘hour’, ts) AS hour, AVG(value) FROM measurements GROUP BY hour.
6. Exporting, saving, and file corruption problems
Symptoms:
- Exports (CSV, PNG, PDF) fail or produce incomplete files.
- Workspaces or project files won’t load or produce errors.
- Corrupt configuration after a crash.
Common causes:
- Insufficient disk space or write permissions in target directory.
- Interrupted export process or sudden application crash.
- Bugs in export pipeline for specific formats or large datasets.
Fixes:
- Verify available disk space and write permissions for the export directory.
- Export smaller subsets to isolate whether size triggers failures.
- Update ADS-Viewer to the latest patch release that may fix known export bugs.
- If a workspace file is corrupted, restore from backup or recreate from minimal saved elements.
- Use temporary directories on local disk for exports rather than network drives that may disconnect.
7. Plugin and extension conflicts
Symptoms:
- UI breaks or features disappear after installing a plugin.
- Startup failures referencing plugin files.
- Unexpected behavior only when certain plugins are enabled.
Common causes:
- Incompatible or outdated plugins with the current ADS-Viewer version.
- Namespace collisions between multiple plugins.
- Plugins overriding core APIs or styles.
Fixes:
- Disable all third-party plugins and re-enable them one-by-one to identify the culprit.
- Update plugins to versions certified for your ADS-Viewer release.
- Review plugin documentation for dependency requirements and conflicts.
- Run ADS-Viewer in a safe mode (if available) that loads only core features.
- Remove plugins that don’t have active maintenance or that cause instability.
8. Logging, diagnostics, and reporting bugs
Collecting clear diagnostic data is crucial when troubleshooting or filing bug reports.
What to collect:
- ADS-Viewer version, OS/version, and hardware specs.
- Steps to reproduce, frequency, and exact timestamps.
- Application logs (enable verbose/debug mode if needed).
- Screenshots, screen recordings, and sample datasets that reproduce the issue.
- Error messages and stack traces from developer consoles or logs.
How to enable verbose logging:
- Check ADS-Viewer settings for a “Debug/Verbose logging” toggle, or edit the configuration file to set log level to DEBUG.
- For crashes, capture crash dumps (OS-specific tools like Windows Event Viewer, macOS Console, or Linux core dumps).
Filing a useful bug report:
- Include minimal reproducible example and attach logs and sample data.
- State expected behavior vs. observed behavior.
- Note any workarounds that temporarily fixed or mitigated the issue.
9. Preventive maintenance and best practices
- Keep ADS-Viewer and plugins up to date with stable releases.
- Use source control for workspace configurations and export important dashboards regularly.
- Maintain schema and API stability for connected data sources; version your APIs.
- Monitor system resource usage and schedule periodic restarts for long-running sessions.
- Implement backup and recovery plans for critical workspace files.
- Establish a staging environment to test upgrades and plugin changes before applying to production.
10. When to contact support
Contact ADS-Viewer support or the vendor when:
- You can reproduce the issue reliably and have collected logs and sample data.
- The problem affects production workflows and cannot be mitigated with available workarounds.
- You suspect a security vulnerability or data corruption risk.
- After basic troubleshooting (restarts, disabling plugins, reinstall) the issue persists.
Provide support with the diagnostic package described above to accelerate resolution.
Troubleshooting ADS-Viewer is often a process of isolating components (data source, network, GPU, plugins) and collecting targeted diagnostics. Start with the quick checklist, reproduce the issue in a minimal environment, gather logs and samples, and then apply the targeted fixes above.
