This release brings major improvements in performance, scalability, and observability. With faster secure communication, high-performance SNMPv3, expanded coverage through Telegraf, and easier probe and tool management, NetCrunch now monitors more systems, responds faster, and scales further than ever before.
A modern encrypted transport and major performance boosts now allow hundreds of remote consoles and probes with up to 200× faster secure communication, delivering smooth management even at large scale.
A redesigned SNMP engine dramatically speeds up SNMPv3 polling, giving customers faster inventory updates, quicker alerts, and better responsiveness on large or secured networks.
Improved sFlow analysis provides clearer insight into top talkers, traffic patterns, and bandwidth usage, helping you diagnose network issues faster.
Communication over encrypted TCP (desktop console and probes) now uses X25519 key exchange, AES-256-GCM encryption, and mutual PSK authentication, delivering TLS-grade protection with no certificates required.
Other channels, such as Web and Cloud access, continue to use TLS 1.2+, ensuring end-to-end security across the entire platform.
Probes can now be upgraded without reconfiguration, with automatic upgrades coming next, simplifying maintenance for multi-site and remote deployments.
NetCrunch now includes an example parser demonstrating how to integrate Telegraf — the open-source, plugin-based data collection agent from InfluxDB. This enables receiving and processing metrics from a wide range of Telegraf inputs.
While this initial release supports selected agent types, it lays the groundwork for a more general integration framework in future updates, ultimately broadening NetCrunch observability across hundreds of Telegraf-compatible data sources.
New and updated monitoring packs, including Fujitsu Primequest, and the Windows Disk , expand coverage and simplify out-of-the-box monitoring.
Gain deeper visibility into device health with SNMP-based hardware sensor monitoring, including temperature, fan speeds, power supply status, and voltage levels—helping you detect failures before they become outages.
Requires device support for ENTITY-SENSOR-MIB.
Custom scripts, commands, and executables can now be added to the node menu, enabling fast, one-click access to your operational or diagnostic tools directly from the desktop console.
NetCrunch 15.2 brings powerful new features and improvements designed to make your monitoring easier, smarter, and more flexible. From enhanced cloud email monitoring to Aruba device support and PRTG import capabilities, this update is packed with tools to help you manage and migrate your networks with greater efficiency.
NetCrunch 15.2 introduces new cloud email sensors designed to monitor cloud-hosted mailboxes using OAuth authentication. These sensors allow you to monitor mailbox availability, perform email round-trip tests, and analyze email data in modern, secured environments.
New alert types have been added to the Windows Service monitor, allowing you to track when services are installed or uninstalled on your monitored machines.
Two new monitoring packs have been added: Aruba Access Point (7 alerts) and Aruba Wired (7 alerts), providing out-of-the-box monitoring tailored for Aruba networks.
You can now easily migrate nodes from the main server to a probe, making transitions from on-premise installations to the cloud much smoother and more efficient.
NetCrunch 15.2 adds a new sensor for monitoring NAKIVO Backup and Replication, giving you better insights into backup operations and statuses.
We've strengthened NetCrunch's password security by improving the way user passwords are hashed and stored in XML files, making it harder for unauthorized access attempts.
NetCrunch 15.2 supports regular expressions for filtering syslog messages and SNMP traps, offering more precise alerting and easier management of incoming messages.
Physical segments monitoring now fully supports Aruba devices, enhancing network visibility and management for environments using Aruba infrastructure.
To support the growing number of users migrating from PRTG, NetCrunch 15.2 now offers a basic import tool. You can quickly bring in devices and essential sensors like PING. After import, NetCrunch can automatically detect and monitor additional services once you provide the necessary monitoring credentials, such as SNMP or Windows access.
We’ve significantly expanded the NetCrunch documentation with over 100 new and updated pages. The refreshed content covers:

Monitor the health and performance of IIS Application Pools effortlessly. Track states, worker process metrics, and ensure uninterrupted application availability.
NetCrunch introduces powerful new features for monitoring Windows processes:
NetCrunch now provides detailed insights into SSL-related issues by displaying error codes directly within the program.
These codes help you identify the exact type of SSL error, making it easier to troubleshoot and resolve connectivity or certificate problems efficiently.
NetCrunch now offers dedicated monitoring packs for Hyper-V virtual machine checkpoints, providing detailed insights into checkpoint statuses. Additionally, the Virtual Machines view has been upgraded to display a comprehensive list of checkpoints for better management and oversight.
We've refined the NetCrunch interface to make your experience even smoother:
Stay ahead of the upcoming Microsoft Teams API changes! NetCrunch now supports incoming webhooks for workflows, ensuring seamless Teams integration beyond January 2025.

Seamlessly embed shared live views into other webpages using iframes, similar to embedding YouTube videos.
NetCrunch 15 introduces critical security updates, addressing 7 key vulnerabilities:
Implemented mandatory password changes for web console users to ensure ongoing security.
You can force users to use MFA when they log in to the Web console locally or through the cloud.
Strengthened password policies, requiring new passwords to be at least 8 characters long.
The new Web Console mirrors the Desktop Console’s UI:
Create telemetry nodes to receive and process metrics, statuses, and events (logs):
The new Desktop Console offers:
Automated Screens have been enhanced and are now available in both the Desktop and Web Consoles:

Monitoring these values helps prevent network issues before they escalate, ensuring smoother network performance and reliability.
NetCrunch 15 introduces a new Network Topology section within the Atlas, streamlining network visualization by combining two critical views:
This new section replaces the previous Physical Segments section and brings the Routing Map (formerly found in IP networks) and Physical Connections (previously a view in the Physical Segments section) together into a single, cohesive interface. This unified approach simplifies network management by allowing you to see both physical and logical relationships side by side, making it easier to understand and manage your network infrastructure.
