WFMReader Troubleshooting: Common Issues and Fixes

How to Install and Configure WFMReader — Step‑by‑Step

1. Prerequisites

• System: Windows ⁄₁₁ or Linux (Ubuntu 20.04+).
• Hardware: 4 GB RAM minimum, 2 GHz CPU, 200 MB free disk.
• Software: Python 3.9+ (if WFMReader is a Python package) or Java 11+ (if distributed as JAR).
• Permissions: Administrator / sudo access to install packages and create service/daemon.
• Network: Access to any internal data sources (databases, file shares, API endpoints) and outbound HTTPS if updates are required.

2. Download WFMReader

1. Obtain the latest release from your vendor or internal package registry.
2. Verify checksum (SHA256) if provided:
   sha256sum wfmreader-.tar.gz

3. Install (two common methods)

• a) Python package (pip):
  1. Create a virtual environment:
     python3 -m venv ~/wfmreader-venvsource ~/wfmreader-venv/bin/activate

  2. Install:
     pip install wfmreader==

• b) Binary / installer:
  1. Run installer (Windows .msi or Linux package):
     • Windows: double-click the .msi and follow prompts (Run as Administrator).
     • Linux (deb):
       sudo dpkg -i wfmreader-.debsudo apt-get -f install

4. Initial Configuration

1. Locate config file (common paths):
   • Linux: /etc/wfmreader/config.yml or /opt/wfmreader/config.yml
   • Windows: C:\ProgramData\WFMReader\config.yml
2. Open config.yml and set:
   • data_source: connection string or file path for input data.
   • auth: API keys, username/password (store securely; use secrets manager if available).
   • logging: log level (INFO/DEBUG) and log file path.
   • schedule: polling interval or cron expression for automated reads.
3. Validate YAML/JSON syntax:
   yamllint /etc/wfmreader/config.yml

5. Database / Credentials Setup

• If WFMReader writes to a database, create the DB and user, grant privileges, and update config with connection URI.
• Store secrets securely (e.g., environment variables, vault) and reference them in config.

6. Start and Enable Service

• Systemd (Linux):
  sudo systemctl enable wfmreadersudo systemctl start wfmreadersudo systemctl status wfmreader

• Windows (Service):
  • Use Services.msc or run:
    sc create WFMReader binPath= “C:\Program Files\WFMReader\wfmreader.exe”sc start WFMReader

7. Verify Operation

• Check logs for successful startup and no errors:
  tail -f /var/log/wfmreader/wfmreader.log

• Run a test read/ingest using a sample file or API endpoint and confirm expected outputs.

8. Configure Monitoring & Alerts

• Add basic health checks (HTTP /health endpoint) and integrate with your monitoring system (Prometheus, Datadog, CloudWatch).
• Configure alerting for failures, high error rates, or stuck schedules.

9. Backup & Upgrades

• Back up config.yml and any local databases before upgrades.
• To upgrade via pip:
  pip install –upgrade wfmreader

• Follow vendor upgrade notes for schema migrations.

10. Troubleshooting (quick checks)

• Permissions: confirm service user can read data paths and write logs.
• Network: test connectivity to data sources (telnet/curl).
• Logs: enable DEBUG if needed and reproduce issue.

If you want, I can generate a sample config.yml for your environment (Linux or Windows) or an example systemd service file.
