  • PRTG Catches Network Issues Before They Cause Downtime Icon
    PRTG Catches Network Issues Before They Cause Downtime

    Threshold-based alerts flag problems early, so your team can act before users notice, not after.

    Reactive troubleshooting usually means hearing about a problem from frustrated users, not your monitoring tool. PRTG sets threshold-based alerts across devices, servers and applications, notifying your team by email, SMS or push the moment a metric crosses a set limit. That means catching a failing disk or overloaded server before it becomes an outage and getting time back from firefighting. Start a free trial and set your first alerts today.

    CSVObjects is a Java library for parsing and unmarshalling comma-separated values into your own JavaBean classes. It keeps record parsing separate from application code: describe the relationship between columns and bean properties once, then iterate over mapped objects. Mappings live in a declarative csv-mapping.xml file. They can model nested beans, skip a CSV header, and apply reusable field formatters before values reach bean setters. The parser is read-only and implements Iterable<Object> and AutoCloseable. CSVObjects requires Java 17 or newer, uses Apache Commons CSV, and is distributed under the GNU GPL version 2 or later
