SolarWinds: AN SNMP based nms
SolarWinds is an SNMP-based complete network management and monitoring solution with well-organized and interlinked features. It is available in five editions: Standard, Professional, Professional Plus, Engineer's and Broadband Engineer's Edition.
What we used is the Engineer's edition. It has nine sets of tools, viz Network performance-monitoring tools, Network discovery tools, Tools for Cisco routers, Fault-monitoring tools, MIB browser tools, Security and attack tools, Ping and diagnostic tools, IP address-management tools and Miscellaneous tools. The information is displayed in a user-friendly interface. It covers all the aspects of FCAPS (fault management, configuration, accounting, performance and security) and includes tools such as ping, subnet calculators and network management and address-management functions.
Under the Discovery set of tools, the IP Network Browser scans the subnet and searches for network devices in it. With Ping Sweep you can ping all the devices and view the result either collectively like machines that have responded or the ones that haven't, or separately. The software can discover MAC addresses of machines along with the details of their manufacturers.
With the Network Sonar you get details of your network devices such as their configuration, statistics and charts showing the status of the nodes on the network. It can also continuously monitor the network and maintain a log. The MIB browser gives you access to specific details of the host with explanations. Bandwidth can be monitored using Bandwidth Gauge. It shows you how much traffic moving in/out at a particular port. To kill remote sessions on a switch/router/server you can use the remote TCP Session Reset tool.
In the Address Management part, you can resolve information about IP addresses and host names and find out if they are being used, when were they last used and response time to pings. With the Monitoring tool you can monitor and ping routers, servers and websites and get their response time and packet loss if any. From here, you can also monitor bandwidth usage by various devices. This is useful for identifying bottlenecks in your network. You can also check for DNS database errors by going for a reverse DNS lookup.
Finally, the Network performance tool tracks the performance of the interface and sends alerts to the network monitoring console whenever there is a violation.
