NetCrunch 9.2 Released: Over 800 changes and 33 new features
Nominally only a minor release, NetCrunch 9.2 is a major step forward. This article will briefly summarize the most important changes out of over 800 changes and 33 new or improved features. Existing customers will have NetCrunch 9.2 added to the customer portal in the coming days, whereas trial users can jump right in, even if they’ve run previous versions.
Major Changes
NetCrunch Users and Access Management
User accounts and access profiles have been redesigned and now both the console and as well as WebAccess use the same accounts for authentication. The new User & Access Rights Manager window is much easier to use than in previous versions. Additionally, various settings are synchronized with user profiles and between the desktop and web console. The new “NetCrunch Audit” Monitoring Pack allows you to monitor failed NetCrunch login attempts.
Administration Console Login
The Administration Console requires NetCrunch Administration access to be assigned to a user profile. We recommend that you create and use separate accounts for each NetCrunch administrator.
Solaris Monitoring and disk monitoring extension
NetCrunch 9.2 includes new a SSH remote monitoring engine and Monitoring Pack for Solaris systems. Additionally, the monitoring of disks has been extended for all Unix family systems.
Integration Module
NetCrunch 9.2 offers integration with several external service desk and messaging services. This means that when NetCrunch opens an external ticket, it can also automatically close this ticket when the alert is closed. Two way integration also allows for the alert to be automatically closed in NetCrunch after the ticket had been closed in the external system. NetCrunch 9.2 supports the most popular services, but more services be added in future versions.
The Integration Module consists of two parts:
- Integration Profiles which allow you to set a communication channel with the external service
- Integration Actions which are used to trigger messages and ticketing actions.
NetCrunch 9.2 currently supports: freshdesk, HipChat, IFTTT, pagerduty, slack, trello, twitter and zendesk.
Event Details
This new window offers better insight into event parameters and implements many useful features. It also allows you to change various alert parameters, analyze alert frequency and allows administrators to add comments.

Monitoring of WebMessages (sending alerts via REST API)
NetCrunch 9.2 adds another tab to the External Events window. Messages can be sent using REST API and using the HTTP protocol from any application. After receiving a message, you can create an alert for it. This feature works in a similar way to syslog messages and SNMP traps.
Alert Management
Redesigned Event Details window
The new Event Details window offers you better insight into event parameters and implements many useful features which give you more flexibility to fine tune alert settings.
- Change various alert parameters. You can easily disable an alert or change its parameters or alerting actions
- Shows the Monitoring Packs where the event is defined and allows you to adjust it if necessary
- Analyzing alert frequency
- Comments can be added to alerts and the last comment will be visible in the event log
- Display a performance chart calculated in the same way as the threshold is monitored
Integration Actions
The Action window contains a new section with Integration actions. These actions also require an Integration Profile to be defined in order to set up communication with external service.
Console and Data Presentation
New Trend Viewer
The NetCrunch trend viewer has been improved in order to better present various metrics collected by the software.
New features:
- More chart display types: trend, trend + range, stacked, and area. Range charts automatically display min, max and average data.
- Custom series scaling and adjustable units
- The ability to compare counters across multiple nodes by choosing the counter first, then selecting the nodes for which it’s been collected
- Various performance improvements
Improved Performance Views
The Bar chart has been improved and uses the same color schemes as the other chart types. Additionally, a small triangle next to the value shows the latest change direction. Charts support SNMP tick unit conversion to standard time units (seconds, milliseconds). All charts perform animations for better change indication.
When you hold the shift key while hovering over performance line charts, the hint window is synchronized and displayed on all charts as below.
Improved charts in reports
Reports charts also use range charts to show min and max values in a given time range.
Redesigned Monitoring Issue Window
This new window allows for easier reviewing and fixing of all issue categories. You can select all nodes affected by an issue and fix it with one click. The window is now also available in the Web Console.
New Node Notes

Smaller UI changes
Ability to disable task auto popup: You can now switch off the auto pop-up feature and only limit the view to blue dots with the number of tasks that require your attention.
New Filtering conditions: You can now create a view for nodes having an IP address assigned or not assigned.
(WebAccess) Node Properties Tab: Node properties are now accessible in WebAccess in read-only mode.

SNMP MIB search improvement: You can use multiple words when searching MIB objects (i.e. cisco status)
Manage Monitoring Packs folders: You can now manage the folders of your Monitoring Packs:
New Windows
