Software Telemetry

Software Telemetry shows you how to efficiently collect, store, and analyze system and application log data so you can monitor and improve your systems.

Summary
In Software Telemetry you will learn how to:

    Manage toxic telemetry and confidential records
    Master multi-tenant techniques and transformation processes
    Update to improve the statistical validity of your metrics and dashboards
    Make software telemetry emissions easier to parse
    Build easily-auditable logging systems
    Prevent and handle accidental data leaks
    Maintain processes for legal compliance
    Justify increased spend on telemetry software

Software Telemetry teaches you best practices for operating and updating telemetry systems. These vital systems trace, log, and monitor infrastructure by observing and analyzing the events generated by the system. This practical guide is filled with techniques you can apply to any size of organization, with troubleshooting techniques for every eventuality, and methods to ensure your compliance with standards like GDPR.

About the technology
Take advantage of the data generated by your IT infrastructure! Telemetry systems provide feedback on what’s happening inside your data center and applications, so you can efficiently monitor, maintain, and audit them. This practical book guides you through instrumenting your systems, setting up centralized logging, doing distributed tracing, and other invaluable telemetry techniques.

About the book
Software Telemetry shows you how to efficiently collect, store, and analyze system and application log data so you can monitor and improve your systems. Manage the pillars of observability—logs, metrics, and traces—in an end-to-end telemetry system that integrates with your existing infrastructure. You’ll discover how software telemetry benefits both small startups and legacy enterprises. And at a time when data audits are increasingly common, you’ll appreciate the thorough coverage of legal compliance processes, so there’s no reason to panic when a discovery request arrives.
