Understand Data Center Network Performance

Corvil Data Center Performance Monitoring

As Data Centers evolve and become more flexible understanding network performance has increased in difficulty. Gaining visibility into the network services that keep the data flowing is crucial to todays network engineer. Understanding and gaining real time visibility into BGP, OSPF, LDAP, DNS and DHCP is critical for keeping applications available to the end user.

BGP, LDAP, DNS Solution Demo

 

Outcomes

  • Understand BGP flapping issues and what routes are advertised
  • Find DNS errors in real time
  • Find LDAP and authentication problems before users do
  • Validate Qos for marked traffic
  • Determine what DHCP servers are oversubscribed
  • Quickly triage and get to root cause of network issues

“We are getting visibility and trust in our ability to monitor for issues we have not had before from other ‘performance’ tools. Everything from the customizations to expose an issue, to viewing the data collected in near real-time has had a profound impact on our organization”.

Problem Overview

Network Services are the basic building blocks of connectivity for the Data Center. Having visibility into these services is critical to ensure application availability. Troubleshooting of these services is difficult and requires packet level detail to understand when something goes wrong.

Challenges

  • Why are my BGP routes flapping?
  • How fast are my current DNS queries?.
  • Why is this traffic not marked EF?
  • Why is this DNS server throwing errors?
  • Customers can’t log into my application is LDAP authenticating correctly?
  • What is the advertised OSPF neighbor for this traffic?

Solution Overview

Corvil provides real-time reporting and troubleshooting of performance issues for Network Services and Data Center environments. Corvils advanced packet capture platform breaks down Network Services for the Data Center giving the network engineer visibility into these services.

Corvil passively taps into the packet data flowing in the network which contains a highly granular and accurate record of all Data Center activity. The Corvil solution uniquely mines this packet data by automatically discovering applications and protocols and reports on a number of key performance metrics. Corvil is a hybrid network probe providing both packet analytics and packet capture on one platform.

Features

  • Live microburst monitoring to help determine packet loss on the link
  • Microsecond granularity to break the 1 minute average that most utilization and flow based tools report on
  • Library of thousands of application definitions to automatically understand what’s on the WAN link.
  • Decodes for DNS, DHCP for better visibility connectivity
  • Views into BGP routes
  • Network Packet Capture only configuration for easy low cost troubleshooting
  • Perform global packet capture from all Corvil devices from a single console
  • Fully decoding LDAP and Kerberos for authentication troubleshooting

Central Management

  • Auto-discover applications and protocols at all instrumented points
  • Central real-time dashboard of all Remote Sites
  • Central search for easy root cause analysis
  • Global search of all packets

Distributed, scalable monitoring

  • Instrument strategic segments of the network
  • Simple architecture to deploy. No need for additional software to get global view
  • Optionally choose to deploy cost effect capture only appliances on remote network segments

Splunk Integration

  • Corvil connector for Splunk
  • Real-time reporting of application messages
  • Sent events and troubleshooting hotspots to Splunk
  • Click back to Corvil for detailed analysis of the event from Splunk
