Application Performance Monitoring in Cardiff
Instrumenting Cardiff organisations' applications so slow and failing requests can be traced to a cause. The constraint nobody mentions at purchase is cost: these tools price on data volume, and a thorough instrumentation left unmanaged produces bills that arrive as a genuine shock.
Why this comes up
The problem
Users report the application being slow, the servers look healthy, and diagnosing it means adding logging and waiting for it to happen again.
What you get
What we deliver
- Tracing across services, so a slow request can be followed to where the time went
- Database queries surfaced, since these dominate most application slowness
- Errors grouped and prioritised by how many users they affect
- Sampling configured to keep cost proportionate to the value of the data
- Attribute cardinality controlled, as unbounded values drive both cost and slowness
- Alerts based on what users experience rather than on server-side averages

Working in Cardiff
Wales
Cardiff has a significant broadcast and media sector alongside a large public-sector presence, and Welsh-language provision is a genuine requirement on public-facing work here rather than a nice-to-have.
Public sector and broadcast work is common, and bilingual provision is usually a requirement rather than an option.

Application Performance Monitoring in Cardiff — common questions
- How does this differ from server monitoring?
- It looks inside the application rather than at the machine. Infrastructure monitoring reports processor and memory; this reports which endpoint is slow, which query is responsible and which users are affected. Servers frequently look entirely healthy while the application is failing people.
- Why do these tools get expensive?
- Because pricing follows data volume, and instrumentation is easy to add. Full tracing on high-traffic services, verbose logging and high-cardinality attributes multiply quickly. Sampling and deliberate attribute choices keep the value while removing most of the cost.
- What is the cardinality problem?
- Attaching values with unlimited possibilities — user identifiers, request identifiers, full URLs — to metrics. Each distinct value creates a separate series, and a handful of such attributes can multiply storage enormously, degrading both the bill and the tool's performance.
- Should we use an open standard?
- Instrumenting with an open standard is generally worth it. It keeps the instrumentation independent of the vendor you send it to, so changing supplier becomes a configuration change rather than a re-instrumentation project. Given how much these tools cost, that optionality is valuable.
- Do you work with businesses across Cardiff?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout Wales, including Cardiff and the surrounding Cardiff area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Cardiff businesses do you usually work with?
- Public sector and broadcast work is common, and bilingual provision is usually a requirement rather than an option. Beyond that we work across Media & Broadcasting, Financial Services, Public Sector, Higher Education and Sport.
- Do you cover the areas around Cardiff?
- Yes — we work throughout Wales, including Bristol, Swansea. Cardiff is an urban area of roughly 490,000+, and we take on work across the wider Cardiff region rather than the city boundary alone.
