Editor's review

This is a network monitoring tool.

NetCrunch lets you do network monitoring. You will be able to monitor network traffic, check connectivity, monitor bandwidth at layer 2, Maps/ VLANs/ SNMP with MIB database. Features related to this monitoring function that are useful include Alert Correlation & Escalation, Windows Event Log Monitoring, SNMP trap server, Syslog Server, Text log monitoring, Remote Actions, etc. It is compatible with Windows, Linux, BSD, Mac OS X, VMware ESXi, etc. It is capable of application monitoring, files and folder monitoring, hardware and software inventory, etc. Monitoring packs help NetCrunch manage to monitor quite easily. They can be automatically assigned based upon rules you set up. There are some 100 predefined monitoring packs for popular systems, devices and applications. Graphics and charts help. This tool is able to automatically create Layer 2 maps, routing maps and automatically manage and update many predefined views. You can define a network map, multiple performance data charts or top charts. You can use your own rules and set them up. This application will do the updates.

This utility is optimized for monitoring a large number of parameters. For example, monitoring a 1000 nodes will mean 30,000 parameters to be tracked and the data generated could easily choke the network. It uses techniques like preventing false alerts, and console protocol optimization, etc. The internal alerts are correlated by default, meaning that the application knows when an alert begins and closes. External alerts (syslog, SNMP traps, Windows Events) will need to be correlated by adding closing events to the defined alert. This tool can execute more actions than only notifications (text messages, desktop and email). It can execute scripts on all the compatible OS environments to get machines/services restarted and set SNMP variables. This is a very good tool.

Publisher's description

NetCrunch 9 is an all-in-one and agentless network monitoring and management system, capable of monitoring every device in your network. Monitor bandwidth, availability, performance, services, NetFlow and more. Automatically generate views and maps and real-time displays. Receive alerts via email, SMS, pop-up, or configure NetCrunch 8 to take automatic corrective actions like restarting a service or running a script.
NetCrunch 9 monitors all leading operating systems like Windows, Linux, VMware ESX/ESXi, Mac OS X, and BSD. All without requiring agents or SNMP.
NetCrunch 9 monitors the performance and availability of 65 network services, including Ping, HTTP/HTTPS, SSH, FTP, DNS, SMTP, and more.
A Netflow traffic server is included, that integrates network traffic flow data from a range of devices using all popular protocols like: IPFix, NetFlow (v5 & v9), JFlow, netStream, CFlow, AppFlow, sFlow, rFlow and Cisco NBAR.
NetCrunch 9 supports all SNMP versions including version 3 with support for version 3 traps. It uses the SNMP protocol to monitor routers, switches, printers, firewalls, sensors, and other network devices. Along with over 7000 included MIBs, NetCrunch 8 also features a MIB compiler so you can easily add new MIBs to the program library.
Open Monitor gives you easy way to connect data from any source, be it an application or a device. It allows for the easy delivery of any counter data to NetCrunch 8. It can be a script (i.e, VBScript, PowerShell, Javascript) running on the NetCrunch Server or an application. Data can also be sent to NetCrunch 8 from any remote system simply using REST API.
With over 100 predefined Monitoring Packs for operating systems and SNMP manageable network devices, NetCrunch 8 can identify, configure, and begin monitoring your network's devices out of the box. Baseline thresholds and range triggers learn your network and alert you to unexpected changes. Monitoring dependencies prevent alert floods.
