Manage a high-performance IT infrastructure
The performance of an IT infrastructure is not just about its availability. It encompasses the ability to meet business needs, absorb peak loads, secure data and ensure business continuity. For CTO, DSI and infrastructure managers, tracking the right indicators is essential to make informed decisions, anticipate incidents and optimize resources. However, companies often lack a clear vision of their actual performance due to lack of tools or methods.
This article presents the main technical KPIs to follow, the risks of insufficient monitoring and the professional solutions available to implement a reliable and sustainable management.
Availability and incident rate: the basis of SLA
The first indicator tracked by any IT management is the availability rate. A critical service (website, ERP, business application) must guarantee a high SLA, generally greater than 99.9%. It is also necessary to measure:
- The average resolution time (MTTR)
- The number of monthly incidents
- The average time between failures (MTBF)
This data allows the assessment of infrastructure resilience and the identification of sensitive points. They are essential to meet commitments towards users and partners, but also to audit the quality of cloud providers or suppliers. Without these data, no structured improvement is possible.
Resource utilization: CPU, RAM, storage, network
The monitoring of physical and virtual resources is an essential condition for performance. A CPU overload, a saturated disk space or an undersized bandwidth can cause slowness, interruptions or data loss. The main indicators to be followed are:
- CPU and RAM usage
- Storage volume occupancy
- Throughput, latency and network loss rate
The goal is to detect bottlenecks before they become critical, and anticipate scalability needs. In a DevOps or hybrid cloud logic, these metrics must be centralized, logged and correlated for effective decision making.
Application response time and quality of user service
IT performance is not only measured on the server side. The end user experience is a decisive criterion, especially in critical applications (ERP, CRM, customer portal...). Key indicators include:
- Page load time
- Application error rate
- Transactional performance
- Service availability score
An application monitoring can detect structural slowdowns, often invisible in a simple monitoring system. It also provides valuable data for development, support or production teams to align technical performance and user satisfaction.
Proactive supervision, alerts and dashboards
The value of an indicator depends on its legibility and ability to alert in real time. It is therefore essential to have supervisory tools that can:
- Collect data from all IT components (servers, VMs, storage, network, cloud services)
- generate relevant alerts
- to produce readable dashboards for technical teams and management
This proactive oversight not only allows for quick action, but also enables performance to be managed over time. It supports better resource allocation, IT investment planning, and the identification of continuous optimization.
Management tools for agile and resilient IT
KPIs are not just technical data : they are indicators of health in your information system. Well-chosen, well-interpreted and well-operated, they allow you to secure your infrastructures, support team productivity and control your costs. It is also necessary to have reliable tools and appropriate support in order to implement them and extract their full value.
At UNIVIRTUAL, we support companies in the supervision, analysis and management of their IT performance. With our advanced monitoring solutions, you get a clear, centralized and actionable view of your key indicators.
