AdRem NetCrunch

NetCrunch is easy to deploy, agent-less network monitoring software for performance and fault management of multi-platform TCP/IP networks. It offers proactive network service, system and application monitoring based on predefined monitoring policies.

It is a unique combination of agent-less monitoring of Windows, Linux, Mac OS X, BSD/Unix, NetWare and SNMP devices in one package. NetCrunch centralises network fault management by collecting and alerting on events from SNMP sources, Windows Event Logs, and syslogs.

Network Discovery

NetCrunch automatically discovers all TCP/IP nodes and creates accurate logical and physical views of the network topology. In order to make the network discovery process complete, the program is shipped with predefined dynamic views and pre-configured Monitoring Polices so each discovered device is automatically classified and added to the relevant views.

• • Discovering network services
  • Monitoring dependencies
  • ICMP & SNMP scanning
  • Device classification

Network Inventory

NetCrunch allows gathering hardware and software data, based on which, the user can manage changes. In order to collect inventory information, the program performs audits.

Network Mapping

NetCrunch's Network Atlas contains all the views and monitored nodes. While some views represent a group of nodes and can be drawn as maps, the others represent real time values of performance counters and they can be shown as charts or gauges.

Network Monitoring (Availability)

NetCrunch monitors the availability of over 65 predefined TCP/UDP network services, including DNS, FTP, HTTP, POP3, SMTP, etc. It monitors the performance of network services measured upon a number of packets sent and received, response time, and percentage of packets received and lost.

The monitored services can be customised and administrators can easily add new definitions.

Monitoring of important services can be performed on multiple levels. As the low level checks only a basic service answer, the higher levels of monitoring check a service specific areas such as authentication (HTTP, FTP, POP3, SMTP) or if a service is operating properly.

Network Monitoring (Performance)

NetCrunch supports the agent less performance monitoring of various network devices (SNMP), operating systems, and applications running on Windows or UNIX/Linux platforms. This is realized by the monitoring of selected performance counters values and by triggering alerts. All the values can be collected and stored for the long term trend analysis.

• • Network Devices Monitoring

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

  • Applications Monitoring

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

  • Monitor Operating Systems

    Program enables the agent less monitoring of servers (Windows, Linux, Mac OS X, BSD and NetWare) from an unified interface. NetCrunch requires the administrator credentials to connect to servers and gather the statistics about the performance of counters.

  • Real-time statistics and trend analysis

    Program presents recently collected data on realtime charts showing the performance of counters over the last hours. It is also possible to view a historical trend of counters with the distribution of values.

  • Threshold Based Monitoring

    It is possible to setup thresholds for performance counters, including a 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).

Predefined Network Monitoring Rules

NetCrunch includes hundreds of rules that define events to be monitored and specify data to be collected for reports. One node can be assigned to multiple monitoring policies; it can also have its own defined policy that may override the map or atlas policy definitions.
