Challenges
Difficulties in Troubleshooting Application Performance Issues
Critical business applications have become the life-blood of today’s enterprises. Delivered across high-speed networks, these services support sales, customer service, financial reporting, and many other core business functions. When any of these applications, or the hundreds or thousands like them, become slow or unresponsive, employees, customers and the business bottom line are affected.
Enterprises now rely on applications hosted across private and public clouds, third-party web developers, and SaaS/UCaaS environments, accessed by users at headquarters, remote offices, and contact centers. With virtually limitless digital paths connecting users to applications, IT teams have less physical control, which slows troubleshooting, especially when IT staff or observability is limited in critical locations.
Outcomes That Matter
Overcoming Application Performance and Observability Challenges
Minimize Service Downtime
Quickly identify and resolve issues with virtually any application with actionable insights that reduce MTTR, improve reliability, and protect business continuity.
Gain Proactive and Predictive Capabilities
Use comprehensive observability that discovers and pinpoints the source of slowdowns before users even realize there is an issue.
Reduce Business Risks
Protect revenue, avoid added costs, maintain productivity, and safeguard compliance and reputation by preventing application slowdowns before they impact the business.
Eliminate War Rooms
Resolve application issues faster with a unified, packet-based source of truth that removes guesswork and accelerates root cause analysis, reducing costly war room escalations.
