Network performance management: Necessities and hurdles

Today’s enterprise IT teams are bogged down by wide–spread networks and complex implementations of applications and services that drive vital business functions such as sales, finance, customer support etc... The need for an all–encompassing network performance management solution that can proactively isolate, identify and resolve impending faults is felt more than ever before.

"...We manage a complex WAN connecting over 200 credit unions across the US. OpManager helps us resolve network outages and troubleshoot performance problems even before our customers notice..." Caria Little, Network Support Supervisor,

"...OpManager and NetFlow have made a huge difference to our Network and Systems teams. Before ManageEngine, we were using a number of different monitoring systems depending on the type and brand of equipment being monitored....Now we have a single application that monitors nearly any piece of equipment we have on our network..." Andrew Harkins, Network Operations Team,

Network Performance Management: Usage Example

Supplemental Healthcare Inc., offers healthcare staffing solutions in 30 different states all over US. Incorporated in 1984 and headquartered in Park City, UT Supplemental healthcare today offers online university for healthcare education and is one of the top 10 healthcare staffing organizations in the nation. At the helm of Supplemental's network is Gordon and his team who work on the "new day-everyday" promise.

More than 500 employees accessing email and other corporate data from the headquarters cutting across 50 different kinds of routers, 40 different firewalls, more than 40 switches, and multiple T1s and T3s. Sounds simple... But imagine a user system getting infected and spiking traffic all over the WAN, or a router memory error causing a bandwidth bottleneck. All these invariably affect the end user productivity. Emails would take forever for a simple fetch... A search request on the corporate CRM could return a blank page... VoIP phones could have degraded voice quality...

A network catastrophe! Gordon however is safe from these nightmares with ManageEngine Network Performance tools...

Syslogs and SNMP Traps provide an excellent way to learn more about device performance and failures. ManageEngine solutions collect Syslog messages from multiple systems and correlate these to provide unique data points that help in root-cause analysis.

Monitor WAN link availability and performance (find latency even over your ISP’s grid)

Top^

Leveraging Cisco’s IP SLA technology, ManageEngine provides you hop-wise visibility on your WAN links’ availability and latency.

Measure network bandwidth and traffic utilization

Top^

Track the utilization of every connected interface and port. Analyze which port has maximum discards and errors.

Analyze traffic usage patterns to know which application or user is occupying bandwidth

Top^

Leveraging Flow based technologies viz. NetFlow, sFlow, IP FIX, etc. analyze network traffic usage and spot which application or user is hogging bandwidth. Isolate network security threats and make better- informed capacity planning decisions.

Enforce best practices, automate network change & configuration management across your network

Top^

Losing sleep and resources to prevent accidental changes to device configurations? With ManageEngine you can automate backup processes across switches, routers, and firewalls. You can restore, in a single click, the last known best configurations. Also get reports on configuration differences and changes and enforce work-flows for upgrading configuration changes.
