Data Center Monitoring

Multi Component Transaction Tracking Across Your Data Center

Corvil Data Center Monitoring

Data Center applications depend on networks, firewalls, load balancers, servers, databases. Corvil is the only all-in-one network data analytics platform that provides precision monitoring and rapid troubleshooting for both the application operations and network management teams. Reporting application and network performance on a single platform enables teams to collaboratively troubleshoot performance issues and proactively report on service quality.

Outcomes

  • Proactively monitor and demonstrate required SLAs across applications, network infrastructure and cloud services across the Data Centre
  • Accurately interpret application and network performance degradation as it happens - allowing an immediate response
  • A single source of IT Performance Data across the Data Centre that enables application operations and network management to report aligned performance metrics

"In our day to day work, Corvil has helped isolate issues to particular data centers, etc. Corvil helps by doing a lot of work I would otherwise have had to manually perform - a slow and tedious task."

Lucas Peet, Sr. Performance Engineer, Interactive Data Corp.

Problem Overview

Data Center applications depend on networks, firewalls, load balancers, servers, databases and other services for their correct performance. When users complain of performance problems, finding the root cause can be an expensive and slow process. Operations teams need to understand how the data centre is performing at all times.

The performance of the servers, firewalls, load balancers, networks and databases can change quickly - due to extra load generated by users, updates pushed into production by application development teams, and the competing demands of other applications or services on the complex set of shared resources.

A myriad of protocols and applications are involved in delivering a service: SSL, HTTP, load balancers, middleware queues, database and storage protocols. Performance measured at the front-door will characterize the overall service but isolating problems requires visibility on the whole chain. Outages or brownouts of critical applications can have a significant business impact on the Data Center’s performance so rapid identification and remediation are essential.

Challenges

  • Data Centre Infrastructure blind-spots - focusing only on the application server's performance risks missing problems at the load balancer, the firewall, the middleware bus.
  • Full diagnosis for a misbehaving transaction involves tracking that individual transaction through each component of the infrastructure to see where along its path the problem occurred.
  • Traditional monitoring tools are siloed - producing independent reports of server load, database performance, statistics from routers. Without a transaction oriented view of the performance, it's difficult to determine which transactions are being affected and where the problem lies.

Solution Overview

Corvil analyses every component of the Data Centre in real time - producing aggregate reports on user experience and the performance of individual components or services. Granular drill-down views show the details of individual transactions at any point in the architecture - with a single click providing a multi-hop view of that transaction's path through the components.

Corvil passively monitors the packet data flowing through the network for a complete picture of the activity within the Data Centre. A library of standard and customised decoding plugins analyses the network flows seen at each hop to provide a highly accurate time-sequenced decode of every message involved in servicing a user transaction. A rich set of metrics is derived from the raw decodes - covering network performance, application error reporting, authentication failures, etc.

The decoded data and the derived metrics are categorised according to business needs - to report on infrastructural components, transaction types, geographical regions, or groups of users. In addition, Corvil ties together the individual tiers to track transactions as they move through the infrastructure to enable quick isolation of the components that are degrading the service.

Corvil offers a lightweight application agent to extend trouble-shooting to critical sections in the server processing (see here for more information).
