FLAGSHIP CASE STUDY
Cdiscount & Peaksys: Azure observability integrated into Zabbix with SenHub
Peaksys, Cdiscount’s tech subsidiary, runs all of the group’s infrastructure — 5,000 servers across Bordeaux and Paris, 17 million unique visitors per month, 1 billion searches per year. When the team moved part of its API management to Azure APIM, the challenge arrived: how do you bring the monitoring of cloud resources into a legacy Zabbix platform painstakingly shaped over years?
The answer: SenHub. The iPaaS platform dedicated to IT monitoring, built by Sensor Factory, let Peaksys monitor its Azure resources (APIM, log analytics, network resources next) without changing its core tooling. 2 years on, the partnership is well established.
“We now have full visibility into our Azure building blocks, and they are integrated into our on-call and operations processes — where before our run teams had no information at all. Azure is operated here just like our internal infrastructure.”
The context
Cdiscount consistently favors in-house development and self-hosting. Around fifty people manage this technical foundation. Zabbix, in place for years, drives operations with roughly 5,500 hosts and over 100,000 triggers that alert the on-call teams and connect to the ITSM.
But when the group moved its API management (essential to its B2B offering) to Azure APIM, Zabbix offered no native Azure metrology. Replacing Zabbix was out of the question: too many years of technical investment and operational procedures to preserve.
The challenge
At decision time, the Peaksys team had two options: build an in-house interface to bring Azure into the run (with zero FTE to spare), or find an external solution that integrates natively with Zabbix.
And the scope went beyond APIM metrology: they also needed to monitor the behavior of the APIs themselves, whose changes (shipped by the CI/CD pipeline every 3 minutes on average) can introduce side effects that must be caught without delay.
The SenHub solution
Thibault Mori discovered SenHub through a LinkedIn post. The platform offered an out-of-the-box Azure resources connector, maintained by a team of DevOps dedicated to IT monitoring. SenHub was designed precisely for this: building on the monitoring tool already in place, pulling metrics (and soon logs) from cloud resources to expose them to legacy tools.
Once permissions were set on the target Azure tenant, Zabbix queries SenHub, which bridges the two. The integration is as simple as importing into Zabbix the configuration file SenHub generates automatically.
To meet the emerging need to monitor APIs beyond their infrastructure, Sensor Factory co-developed a new Azure log analytics connector that turns logs into usable metrics — giving business teams error-code and performance tracking right inside Zabbix.
“Having error-code and performance metrics surfaced back into Zabbix for the business teams is a major gain, with real impact on day-to-day operations.”
Outcome and outlook
After 2 years, the verdict is clear: Azure resources are no longer a blind spot in monitoring. Every technical incident is handled by teams alerted through Zabbix, in the same processes as an on-premise resource.
What comes next is already underway: a rebuild of the Azure tenant into landing zones and a hub-and-spoke architecture (network resources, load balancers, firewalls monitored via the Azure filtered metrics connector), and the integration of Kubernetes platforms and Azure Monitor — without rolling back the 600+ alerts already automated. SenHub is API-first: its configuration is fully driven from Terraform and the Peaksys CI/CD pipeline.
On the horizon: integrating Azure OpenAI and Azure ML instances — to apply the same industrialization logic to the AI stack being rolled out at Cdiscount.

LNA Santé: monitoring 89 healthcare facilities from Nantes, with no IT on site
In healthcare, an application going down is never a mere technical incident: it directly affects patient care. At LNA Santé, that requirement comes with an unusual constraint — no IT staff are present on the sites. The group’s 89 facilities (10,658 beds and places, 9,000 employees, across France, Belgium and Poland) are run from a single data center at headquarters in Nantes.
Making such a model work demands blind-spot-free visibility across the whole estate — and a partner able to build it for the long haul. Since 2017, that has been Sensor Factory’s role: not to deliver a tool, but to design, adapt and sustain the monitoring that lets the IT department see everything, and act before users do.
The context
LNA Santé built its IT on a defining choice: a centralized, shared infrastructure. A single data center at headquarters hosts the applications and delivers them to every facility via Citrix; the most sensitive health data lives with an HDS-certified host, as the regulations require.
This model has a direct consequence: everything is run remotely, with no local technical relay. The slightest drift — a saturated link, an unresponsive application, an overheating server — has to be seen from Nantes, immediately. The free open-source monitoring tool used until then could no longer keep up: impossible to maintain properly against a continuously growing estate.
The stakes
The IT department’s need came down to one sentence: complete, real-time visibility into the availability of every building block — networks, servers, telephony, business applications — across all the remote sites.
But the tool was not enough. They needed someone to install it close to real usage, to cover the specific applications no off-the-shelf solution monitors natively, and to pass the mastery of the whole setup on to the teams. In short: an operations partner, not a license vendor.
Sensor Factory's answer
In 2017, LNA Santé chose Sensor Factory, a Nantes-based monitoring specialist, and deployed the solution best suited to its context (PRTG) with it. The tool is only a starting point: the value lies in how it is tailored to LNA.
“Beyond simply integrating a monitoring solution, we absolutely needed to be supported by a true partner — one able to help our teams optimize how the solution is operated and to put highly operational processes in place. Sensor Factory won us over with its rigor and expertise.”
Covering the 20% that matter. The standard base meets 80% of the needs. For the rest — in-house applications, specific components, devices not natively recognized — Sensor Factory develops custom sensors, until it monitors what the tool alone ignored.
Two readings of the same reality. Technicians work from finely tuned alerts and detailed dashboards; management tracks the health of the IT estate at headquarters and across the 89 sites on real-time maps shown on big screens, where each facility turns green or red at a glance.
A single window onto the whole IT estate. Physical equipment, applications, VMware Cloud Director consoles: Sensor Factory consolidated heterogeneous sources into one view — work that, along the way, helped LNA map its own information system more clearly.
The results
9 years on, monitoring has changed in nature.
The IT department has shifted from reactive to preventive: most incidents are detected, and resolved, before a single user notices. The time saved on resolution has been reinvested in higher-value projects. And the drop in downtime shows up in black and white in the monthly satisfaction surveys run among care staff.
And the essential point, in a field where technical teams turn over: continuity of know-how. By staying alongside the IT department year after year, Sensor Factory preserves a fine-grained knowledge of the estate and is now helping LNA take the next step — scenario-based application monitoring and formalized SLAs.
