Live Visualization

Flexible UI

While checking a node state you can also see its physical connections, and all views which include this node. In one click you can explore switch ports, VLANs, and connections.

Alerts, Network Traffic, and Performance views - everything is linked, especially useful for troubleshooting network problems.

You can do things efficiently. For instance, you can easily select multiple nodes and change their settings with only one click.

NetCrunch comes with desktop, web and mobile consoles. The desktop console has been optimized for Windows 10 tablets.

Finally, in NetCrunch you can find diagnostic tools for Windows: These include WMI Tools, IP Tools and an SNMP Viewer which allows you to easily explore or change data on supported SNMP devices (switches, printers, routers, etc.).

Analytics & Database



    NetCrunch includes many pre-defined reports. Reports are generated in PDF format. Reporting tasks can be run ad-hoc or scheduled (daily, weekly, monthly), and reports can be distributed automatically by email. Users can also create their own reports based on collected performance data.


    Performance Trends Analyzer

    The Trend Analyzer allows you to analyze and compare historic performance metrics collected by NetCrunch. You can compare different metrics or see value distributions by hours or days of the week.


    Network Traffic Trends

    NetCrunch contains a Flow Server which uses an analytical database for ad-hoc traffic analysis of up to 1hr. The program allows you to collect long term performance trends for given nodes or globally aggregated traffic data.


    Event Database

    NetCrunch stores all events in a built-in SQL database. No external database is required, which reduces the overall cost of installation and administration of NetCrunch. Each event generated or received by NetCrunch is stored in the event database. NetCrunch can also remotely collect events from Windows Event Log or monitor Text logs using the file sensor. The database can retain event data up to 100GB, and is also accessible for reading by external programs through the ODBC driver.


    Performance Data Database

    NetCrunch uses a noSQL database for storing network performance data, which is compressed daily. This database is file based and can hold data as long as needed. Data can also be removed after a certain period (months, years). Data from this database is accessible for querying and exporting through a separate tool included in NetCrunch. Historic monitoring data can be exported to external databases (MS SQL, MySQL, Oracle, etc.). The data export tool can be scheduled to run automatically.

  • Why NetCrunch?

    AdRem Software has been developing software for networks since 1998. We started by providing successful tools for Novell networks, and after that we started developing our flagship network monitoring system which was first released in 2001.

    We release NetCrunch updates 4-5 times a year, adding new features in every minor release.

    We provide worldwide tech support by our in-house engineers. Support requests are answered in less than 24 hours on business days. You can also access our online knowledge base

    We offer free pre-sales tech support and provide installation assistance for you. Our partners offer consulting, on-site support and training.

  • High Performance & Security

    NetCrunch is optimized for speed, and can easily monitor up to 3,000 nodes from a single machine. A single instance of NetCrunch can track over 600,000 performance parameters!

    NetCrunch combines different technologies for the best results: A noSQL proprietary database for network performance metrics, an in-memory database for fast real-time status, and an embedded SQL database for storing alerts.

    To achieve the best results even when working remotely over slow links, NetCrunch uses advanced techniques like: false alert suppression and console protocol optimization.

    All program components are secured with industry standard cyphers. Web consoles can use SSL for connecting to NetCrunch. The Remote Administration console uses encryption and compression for accessing the server remotely.

  • Simple Licensing Model

    NetCrunch is licensed per number of monitored network nodes, which is more logical than counting probes or sensors, and scales efficiently. A single node always counts as a single node, regardless of the number of sensors, services or applications being monitored on it. A 48-port switch or server running multiple applications counts as one node, period.

    Compare the NetCrunch licensing model to other models

  • Self Monitoring

    NetCrunch monitors itself. It monitors hundreds of software component parameters and warns you in case of slowdowns or problems. NetCrunch is designed to survive overload conditions which can happen in case of network device failure (generating thousands alerts per second).

  • Extensibility & Customization

    The NetCrunch UI is flexible, can be used on multiple screens and supports window docking. NetCrunch includes a MIB compiler so it can be easily extended with new vendor supplied SNMP MIBs. NetCrunch works with scripts, can be easily fed with data and can execute custom scripts.
