Kadiska monitoring helps Leroy Merlin reduce problem resolution time from weeks to hours, and optimize SaaS retail apps, GCP cloud and SD WAN performance



Leroy Merlin is a leading multinational home renovation, decoration and gardening supply retailer with over 250 stores in 15 countries across Europe, Brazil and South Africa, supported by over 30,000 employees.

Leroy Merlin transformed their retail operations to launch a multi-channel sales model, increase in-store services and to optimize customer experience, employee productivity and store efficiency. In this context, many in-store services were digitized and shifted to the cloud. Services delivered from SaaS and cloud platforms are integrated with private data centers and third-party services.


A New Essential: Store to SaaS and Cloud Connectivity

The network performance between stores, digital retail applications and cloud-hosted business systems has a direct impact on the usability of self-service checkouts and employees’ ability to stock shelves and serve customers. It also impacts in-store advertising, supply chain efficiency and each store’s ability to reach their monthly sales objectives.

To assure success, Leroy Merlin ‘s IT organization decided to adopt an analytics-driven reliability engineering approach to proactively optimize the performance of business applications and SD WAN connectivity.

However, they discovered that existing monitoring solutions were unable to detect and diagnose network performance issues between stores, clouds, data centers, SaaS apps and third-party services.



Leroy Merlin needed a new level of monitoring to eliminate visibility gaps induced by SD-WAN, 3rd party services and SaaS/cloud applications to:

  • Optimize store connectivity to clouds and SaaS services
  • Reduce incident impact and resolution time
  • Effectively collaborate with vendors and service providers
