NetFlow application classification has been extended to support Cisco NBAR technology (Network-Based Application Recognition).
Allows to monitor files over HTTP protocol. It can check its presence, its size or modification time. It also allows you to search the file content or can be used for finding new text log entries.
Allows you to send simple HTTP requests like GET, HEAD or POST and check the response code or search for text in response content. It supports regular expressions for text analysis. It also allows you to measure response time and response length.
Tiles about Monitoring Packs and Network Services are fully clickable, details about which nodes are affected are shown in popup after click.
Sensor summary for sensor based monitors is available on Summary Dashboard and in Node Status Window.
Now you can compare trends for displayed values with one click.
There are 8 new pre-defined event log views/filters to display only Syslog or SNMP traps or Web Page/HTTP events and others.
Now you easily can drag tiles and zoom in dashboards using touch screen.
Now you can add one of 7 data widgets that can display live performance data on maps. Using status widget you can convert numerical values into more readable status text and icon.
Available widgets include: Text and Value, State Lights similar to traffic lights, Value with percentage bar, Battery bar, Circular gauge, Simple gauge
In administration console you can set automatically switching between atlas views and pages (map, summary, top charts) at full screen.
Console supports multiple screens and switching scenarios. You can use one screen for displaying automated screens while using another monitor for interactive work.
New text sensor is allowing triggering alerts based on mail Subject or Sender fields.
The content of the email can be added as parameter to triggered alerts.
Sensor is also allowing of monitoring number of emails in mail box and total size of mail box emails.
NetCrunch 8.5 provides 4 monitoring packs for NetApp, that include reports and alerts defined to track NetApp health.
NetCrunch 8.5 contains more than 350 changes and fixes.
New action allows to send REST requests (POST) in response to a NetCrunch alert. This allows for easy integration with external cloud services.
New summary dashboard displays much more information using the same screen space. The dashboard can be zoomed to adjust to your screen resolution.
New dashboard sections include:
Pending alerts
All performance parameters are grouped and displayed in an easy to navigate view. Now you can easily spot parameters breaching thresholds.
New charts have better layout and allow for displaying up to 10 elements without scrolling. You can zoom them to adjust to your screen resolution.
New predefined charts:
Layer 2 monitoring has been upgraded to a new optimized SNMP engine and is now 5 times faster than in previous versions. This is important for switches with a large number of ports.
New mailbox sensor allows monitoring mail server by checking full mailbox functionality (SMTP/POP3/IMAP). The sensor send email and receives checking if the server properly receives emails.
Starting from version 8.4 we improved 10 times performance of SNMPv3 monitoring which is processive intensive due encryption.
Additionally, default SNMP protocol used by NetCrunch is now SNMPv2. Program also uses bulk SNMP request when possible to lower network footprint.
The "WMI tools" program has been updated and simplified. It gives the ability to access WMI data remotely and built own views using WQL queries.
File sensor allows to monitor file presence, it's size or modification time. It also allows to search file content or finding new text log entries.
New folder sensor allows to watch specific folder content when a new files are added or any files are removed.
In version 8.4 you can check files and folder using windows (SMB), FTP, SFTP or FTPS protocols.
NetCrunch 8 comes with over 100 Monitoring Packs containing monitoring settings for popular applications and devices.
NetCrunch built-in MIB database contains about 300,000 SNMP objects. So we decide to improve searching the database. You can also now create bookmarks to MIB tree. Adding multiple SNMP counters has been also improved.
We’ve extended our monitors beyond core OS services to support objects and applications. The monitors target files, queries, Web pages, etc.
In version 8.4 has been extended support for handling different login schemes (support for standard HTTP authentication and custom scripts).
A sensor for monitoring Apache Web Server.
A sensor that allows users to check results of various DNS queries. It issues alerts when the server does not respond or responds improperly to queries.
An advanced sensor that monitors dynamic pages with JavaScript. It loads all page resources (like a Web browser) and issues alerts on load errors and load time. The analysis includes the execution of JavaScript and a check for content and text changes.
NetCrunch 8 supports floating point numbers in performance data. Both processor utilization and bandwidth now can be calculated and tracked with high floating point precision.
NetCrunch 8 can decode encrypted SNMP v3 traps (TRAP and INFORM packets). SNMP profiles have been extended with the additional notification profiles. NetCrunch can also forward SNMP v3 traps.
NetCrunch capacity depends on the monitored subjects and the hardware is server running. NetCrunch 8 introduces new dashboard showing NetCrunch server state. It helps you to identify the case when program is overloaded. It also shows links to all logs written by all NetCrunch components (backup, sensor engine, report engine, NetFlow server, etc.).
External alerts (syslog, SNMP traps, Windows Events) can be easily correlated by adding closing events to the defined alert.
All internal alerts are correlated by default, so NetCrunch knows when the alert begins and when it is finished (closed).
Version 8 simplifies alert actions by adding the action executed when the alert is closed.
Additionally, when the program receives a correlated event, it automatically closes the alert and marks it as resolved`.
NetCrunch 8 adds new alert triggers for performance counters available to every monitor, including Open Monitor
This trigger works after collecting data for one week. You can set the threshold on the deviation from the baseline calculated by the program (by percentage or value).
This trigger is attached to the allowed (or disallowed) range for the value, and is much easier than setting up two separate thresholds. The trigger is reset when the value falls into range with the given margin.
NetCrunch 8 allows users to set thresholds on average values calculated from a number of samples. As the monitoring of the data can vary for different nodes this is a more convenient way to set alerts for multiple nodes.
The node configuration has been completely redesigned. There are only 4 tabs in the window now, compared to 11 in the previous version. Now, you can set alerts and monitoring settings for sensors and services in one place. Configuring NetCrunch has never been easier and faster.
NetCrunch 8 extends support for Unix family systems. It supports the newest versions of Linux, BSD and Mac OS X, and adds new views in the node status window. It allows the display of: Processes, Opened Files, TCP Connections and Unix Sockets..
A new drop-down window presents a clear summary of alerts in a given time range. The window also allows users to select and manage custom event log views.
The desktop notification window has been redesigned and improved.
We’ve updated the interface with a new window to support the larger number of Monitoring Packs. The new window also allows Monitoring Packs to be imported and exported.
A search option has been added to multiple windows, making it easier to search Monitoring Packs, counters, actions, events and nodes.
In addition to tracking alert correlation and automatically closing alerts, the improved event log database displays only relevant (open) alerts. The database performance has also been greatly improved; writing of new events is now more than 10 times faster than previous releases.
NetCrunch 8 adds another 1500 MIB modules to the database, for a total of almost 1GB (13,000) of source MIB files.
The user interface has been updated. NetCrunch can also now perform a Full Backup containing all server configurations (including registry settings).
The NetCrunch 8 icons set has been updated to reflect the increased range of devices that can be monitored.
