Event Management & Alerting (3rd of 11 themes)

What can it do for you?

NetCrunch unifies fault management by collecting and alerting on events received from a variety of external sources such as: Windows Event Logs, Syslog or SNMP traps.


Features:

Event Sources

NetCrunch processes events coming from a variety of sources. Some of them may be external like SNMP Traps or Windows Event Log entries and others generated by NetCrunch like Monitoring Events (node state changed) or Atlas Events (like new node discovered).
 

Alerts = Events + Actions

When NetCrunch Event Manager receives an event, it is first written to the Event Database, then the program processes and executes the actions defined for the event. Actions can be defined on different levels, for each node or group of nodes (map, atlas). The event database is fast and scales up to 128GB of data. The event data are also accessible through ODBC driver.
 

Alert Escalation and Correlation

Actions assigned to an event can be performed immediately or after some time if the event has not been cleared. Most of the built-in events are correlated and when the event condition changes they are automatically cleared. For example, when a given event is received by NetCrunch, the desktop notification is immediately displayed. If the alert is not acknowledged or cleared within the next 15 minutes, the computer may be restarted.

Availability Monitoring (4th of 11 themes)

What can it do for you?

NetCrunch monitors all your network services with the help of over 65 built-in Network Service monitors and advanced user experience monitors (HTTP/S, POP3, FTP, SMTP, DNS).


Features:

Basically everything connected to the network can be considered as a service. If there is a device on the network it always suits its purpose which is exactly providing a service. There are only different methods of checking the availability of those services.
 

Basic Level

Some of the services (devices) can be checked by a simple PING whereas others can be checked more thoroughly by Network Services monitors. These monitors are called intelligent pings because they can check not only the connectivity but also received responses. NetCrunch monitors the availability of over 65 predefined TCP/UDP network services, including DNS, FTP, HTTP, POP3, SMTP, etc. It can monitor network services performance measured upon a number of packets sent and received, response time, and the percentage of packets lost and received. The monitored services can be customized and administrators can add their own definitions.

 

Advanced Level - User Experience Monitors

The monitoring of some important services can be performed on multiple levels. As the low level checks only basic service answer (it's usually some kind of HELLO), the higher monitoring levels allow checking more specific things like authentication (HTTP, FTP, POP3, SMTP) or if the service works properly (i.e. downloads file, receives and sends test emails).

 

HTTP/HTTPS

NetCrunch allows monitoring multiple URLs, and checking their availability. The program can also monitor page header or any content modifications. This ensures the proper display and desired content of the websites.

 

POP3

The program can periodically authenticate to the POP3 service with given credentials, thus confirming that e-mail users can successfully access the service.

 

SMTP

NetCrunch allows sending test email messages to a specific e-mail address. If SMTP service is unable to send the message, administrator is notified about it.

 

FTP

NetCrunch can authenticate to the FTP server. It can also monitor the directory file list and send notification if any change occurs (e.g. if any file has been modified or removed). Additionally, it can perform the file download test. It enables administrators to control the changes of FTP server content.

 

DNS

NetCrunch can resolve IP address or DNS name to verify if the DNS service response matches the expected pattern (defined by administrator in NetCrunch). It allows discovering unexpected (or even unauthorized) DNS changes.

Performance Monitoring (5th of 11 themes)

What can it do for you?

NetCrunch monitors real time values shown on charts, bars and gauges. Multiple nodes performance can be compared on a single chart. There may be different reasons to monitor the performance of a network. First of all, to check the quality of a given service, usually measured by the response time and availability time. The other might be future expansion planning, when bottlenecks need to be identified and fixed.


Features:

NetCrunch allows agentless performance monitoring of different network devices (SNMP), operating systems, and applications running on top of Windows or UNIX/Linux. This is realized by monitoring selected performance counters values and triggering alerts. All those values can be collected and stored for later long term trend analysis.

Statistics Real-time (6th of 11 themes)

What can it do for you?

NetCrunch presents recently collected data on real-time charts showing counters’ performance within last hours.


Features:

To generate reports, NetCrunch automatically initiates data collection, based on monitoring policies definitions. Reports are also generated on demand or periodically delivered by e-mail to selected recipients.

Trend Analysis (7th of 11 themes)

What can it do for you?

With NetCrunch you can view counters’ historical trend with values' distribution.


Features:

Trend Viewer

Data collected by NetCrunch can be used for reporting or on demand trend analysis. There is a seperate tool called "NetCrunch Trend Viewer", specifically designed for this type of analysis. It's also accessible remotely through the Web Client. Performance history of a single counter can be compared across multiple nodes on a single chart to determine under and over-utilized resources.

Exporting Trends

For further analysis and to diagnose using external reporting tools, users can export the data collected by NetCrunch to an industry standard databases including: * MS SQL Server 2000/2005 * MS Access 2000 or higher * Oracle 9i/10g * MySQL 5.x * Interbase 7.x * ODBC Data Sources * MySQL 5.0.18 via MySQL ODBC 3.51 Driver * DBISAM 4.x.

Treshold Monitoring (8th of 11 themes)

What can it do for you?

With NetCrunch you can setup thresholds on performance counters (Threshold Based Monitoring).


Features:

NetCrunch thresholds on performance counters, includes basic level (counter value exceeds/drops below threshold value), existence (any value received/not received from counter), state (counter value equal to threshold value for specific period), and unexpected change (counter value deviates from average of recently received values by specific percentage).

Network Device Monitoring (9th of 11 themes)

What can it do for you?

NetCrunch supports monitoring of many hardware devices using SNMP v1-3. It can actively check SNMP counters or passively receive SNMP traps or syslog messages.


Features:

NetCrunch uses the SNMP protocol to monitor routers, switches, firewalls, sensors, and other network devices. It is possible to monitor bandwidth, user activity, hardware utilization, and many more. NetCrunch can actively check performance counters, or passively receive SNMP Traps from network devices. The program allows setting thresholds and can notify the administrator about hardware issues. The collected data is used for troubleshooting and long-term analysis. The program comes with a pre-compiled MIB library containing over 2500 MIB modules including CISCO, Nortel, 3Com, Alcatel etc., and can manage many more. Users can easily add new MIBs to the library using the program's built-in MIB Compiler. The MIB Compiler is able to solve vendor MIBs specific issues.

Application Monitoring (10th of 11 themes)

What can it do for you?

NetCrunch offers performance monitoring of applications running on Windows or other systems (Linux, NetWare, Unix, etc.). For systems like Windows or NetWare, the program retrieves performance data using system protocols (RPC, WMI, Win API, NCP). For other systems (Unix/Linux and other) SNMP agent can be used.


Features:

Windows

NetCrunch can monitor applications running on Windows hosts by reading their performance data directly from operating system counters. For each available application counter, users can configure events that trigger notifications or corrective actions. As a result, it is possible to track crucial application services, such as directory services, web, email, database and network services. For example, to track Microsoft Exchange it is necessary to monitor POP3 and SMTP services, some Exchange performance counters and Exchange windows services.

NetWare

NetCrunch allows performance monitoring of applications running on NetWare servers. Users can setup application-related events on network services like POP, and SMTP to track GroupWise applications. NetCrunch provides an easy way to monitor, alert and report on the performance of all the NLMs. To do that, NetCrunch retrieves performance data from native NetWare counters.
 

Network Services

The program delivers out of the box monitoring for over 65 TCP/UDP network services and allows defining custom service monitors. Users can monitor almost any application working as a network service by tracking the performance and availability of the service. Performance of service is measured upon: * number of packets sent and received * response time * % packets received and lost * last sent/received time SNMP.

NetCrunch provides extensive monitoring of applications working on the systems that support SNMP v1, v2 or v3. By handling SNMP traps and retrieving information from application-related SNMP monitors, NetCrunch can monitor and alert on metrics such as: * traffic utilization * conversations * error conditions * resource utilization * response time * data captures.
