Network Performance Monitoring

There may be different reasons to monitor performance. First one, may be to check the quality of given service usually measured by response time and availability time. The other might be future expansion planning - we want to identify bottlenecks and fix them.

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 analisys.

Network Devices Monitoring

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

Operating Systems Monitoring

Program enables agentless monitoring of servers (Windows, Linux, and NetWare) from unified interface. NetCrunch requires administrator credentials to connect to servers and gather statistics about performance counters.

Application Monitoring

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

Real-time Statistics and Long Term Analysis

Program presents recently collected data on real-time charts showing counters’ performance within last hours. It is also possible to view counters’ historical trend with values' distribution.

Threshold Based Monitoring

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