Solarwinds NPM (Version 11.5)
The Solarwinds network performance monitor application typically targets enterprise-level environments rather than small and mid-sized companies. The product is primarily designed to monitor the performance of network devices. If a company needs to monitor actual network traffic, application monitoring, or other forms of monitoring such as eventlog / syslog monitoring, they would need to use a different product and / or purchase additional modules within the Solarwinds suite. These include Netflow Traffic Analysis, WAN and VoIP QoS performance monitoring, Log & Event Manager as well as several other modules. Although Solarwinds provides network packet analysis with their Quality of Experience module, this feature requires a sensor to be installed on each individual servers or dedicated machine / network device to provide traffic analysis. When tested, the configuration for the QoE module requires the user to configure every type of network traffic (network protocol) that they wish to monitor / analyze on a per device basis. In a large network environment, configuring sensors for ALL different types of network traffic for hundreds (/ thousands) of devices would be a daunting and time consuming task. Support for Netflow Traffic analysis – Solarwinds has an additional module / application called the Netflow Traffic Analyzer (currently at version 4.1.2) available for an additional cost that can be integrated with the NPM product to provide a more enriched level of traffic analysis. This software supports Cisco® NetFlow, Juniper® J-Flow,sFlow®, Huawei NetStream™ & IP FIX flow data. The data collector captures and analyzes the flow data that is integrated into most routers and converts that data into easy-to-interpret charts and tables that quantify how the network is being used, by whom and for what purpose. Network Availability & Performance Monitoring – Solarwinds monitors network device and interface availability, performance indicators such as bandwidth utilization, packet loss, latency, errors, discards, CPU, and memory for SNMP and WMI-enabled devices. Syslog Monitoring – Solarwinds has an additional module / application (Kiwi Syslog Server) available for an additional $295.00 per install cost that receives syslog messages and SNMP traps from network devices (routers, switches, firewalls, etc.), and Linux®/Unix® hosts. You can filter and view these messages based on time, hostname, severity, etc., and set up custom alerts.
Netmon (Version 6.2)
Netmon is sold as a complete appliance and software solution, and targets midsize to enterprise level environments. Netmon includes a suite of monitoring tools with a focus on providing a device centric vantage point of the network. Its main differentiator is that it can provide real time network traffic analysis without any additional modules / purchases (i.e. Netflow, JFlow or a separate Sensor that must be installed on a separate Server). Netmon’s traffic analysis engine is practically plug and play. The appliance comes with an additional network interface on the appliance (and is further expandable) that can simply be plugged into a port-mirrored interface on a core network switch (or switches). Once the IP Packet Analyzer service is enabled, traffic analysis is fully functional and it provides immediate feedback including (on the Home Dashboard) top network activity – who is talking to who, a protocol analysis graph and the visual network explorer which displays the top network conversations on the network. Netmon includes a data collector module which supports Cisco® NetFlow and sFlow and integrates that data the exact same way that it presents the sniffed traffic from its traffic analysis engine. This allows multiple protocol analysis graphs to be shown on the home dashboard representing both sniffed traffic from the integrated local network traffic analysis engine as well as Netflow traffic streams that can be configured on routers (cisco) at remote locations and then sent to Netmon for a complete multi location network view and breakdown. Network Availability & Performance Monitoring – Netmon monitors network device and interface availability, performance indicators such as bandwidth utilization, packet loss, latency, errors, discards, CPU, and memory for SNMP-enabled devices. Netmon provides the ability to import custom SNMP MIBs for monitoring specific and more granular performance metrics. Since Netmon does not currently support WMI (which is a Microsoft-centric technology), it provides a custom dashboard for all Windows devices utilizing a free SNMP agent for monitoring performance metrics on Windows Servers, and Workstations (i.e. CPU, RAM, Disk I/O metrics etc.). Syslog Monitoring – As part of a full featured monitoring system Netmon includes the ability to receive SYSLOG messages from network devices (routers, switches, firewalls, etc.), and Linux®/Unix® hosts. You can filter, view and create custom alerts for these SYSLOG messages based on time, host, severity and alert message.
A cost comparison based on monitoring 1000 devices – Since the two products have a completely different sales and pricing models, assumptions had to be made in regards to hardware requirements and cost, additional software modules (based on the monitoring capabilities in the chart above) for Solarwinds.
