How a Tier-1 European telecom operator beat alarm fatigue and regained control

Every day, telecom operators are hit with a relentless avalanche of alerts. Ranging from tens of thousands to millions. Most are duplicates, false positives, or just noise. And yet every single one demands attention. Teams burn out, resolution times crawl, and the alerts that actually matter get buried. 

More complexity equals more noise  

When everyone’s tech stack looks more or less the same, it’s how fast you respond—and how well you deliver—that sets you apart. So the pressure to deliver better, faster, and cheaper has never been higher. But instead of moving faster, operators are stuck in the mud, trying to make sense of a firehose of alerts.

Why? Because the platforms behind modern services are nothing short of Frankenstein-like. We’re talking thousands of resources stitched together across dozens of EMS and NMS systems—each one speaking its own language, tossing out alerts in different formats and standards.

Worse still, most teams don’t have a central playbook. They’ve got hunches. Gut checks. Maybe a spreadsheet. New team members are left trying to decode cryptic alerts, asking, “Hey, has this one popped up before?” It’s a nerve-wracking way to run a network—and a fast track to escalations and missed SLAs.

How DataMiner cuts through the noise  

One of our users—a major pan-European pay-TV operator—found themselves exactly in that spot. Their NOC team was drowning in over a million alerts per day at peak times. With 3,000+ resources spread across 25 different management systems, manual triage was simply impossible. So they brought in DataMiner. 

First came the big clean-up. Thanks to automated deduplication, correlation, and false-positive filtering, alerts stopped piling up like junk mail. But the real stars of their NOC show are the 200+ active policies, which filter for actual service impact and turn those filtered alerts into actionable incident tickets, complete with the right context.  

They also rolled out automated remediation workflows for high-priority incidents. Now, when a known critical issue hits, the system kicks into gear before anyone’s even had time to panic. And by switching to DataMiner as a Service (DaaS)—our cloud solution—they cut their infrastructure maintenance costs way down and gave global teams secure, remote access without any headaches. 

Silence is golden 

Before DataMiner, triaging an alarm was like trying to defuse a bomb with half the instructions and someone shouting in your ear. There were just too many alarms to sift through and the NOC team had to rely on tribal knowledge to do so—which worked OK until someone went on vacation or a rookie joined the rotation.  

Now, alerts come pre-triaged, context included. The team can move straight to resolution mode, without wasting time on false leads. And that means faster time to resolution, increased uptime, and happy customers.  

We believe that operators shouldn’t just survive the flood of alarms—they should own it. DataMiner empowers them to cut through the noise, focus on what really matters, and keep services running smoothly. And it gives the team time to enjoy that long-overdue cup of coffee, too.
