Summary
An outage costs money every second, and in most data centers, root cause analysis (RCA) means a manual hunt for answers across multiple systems and stitching solutions together by hand. Put every reading from every system on one timeline, with its asset context attached, and that hunt becomes a single unified query. Your team sees what failed first, triages failures in real-time with AI assistance, and answers a customer billing dispute with the same data. Telegraf, InfluxDB 3 Enterprise, and InfluxDB Cloud unify that timeline.

Why RCA takes so long in a modern data center
A GPU server started running hot, and the DCIM threw up the first alarm, followed by the BMS reporting a cooling unit failure and the EPMS logging a power dip. Unfortunately, none of the three alarms alerted the team that these incidents happened in tandem. To work out which came first, a tech opens every system, exports data, and lines up the timestamps by hand.
If you work in data center operations, you’ve probably been the one lining up those timestamps, or the one waiting on them. The data that explained that incident was already sitting in all three systems before anyone went looking; the slow part was getting three systems’ records into one place, in the right order.
Keeping cooling, power, and IT in separate systems makes sense, because the BMS, EPMS, and DCIM were each built for one part of the facility. A single incident, though, shows up in all three at the same time, and each system holds one key part of the story. Today, finding the root cause means hunting down those parts and stitching the records together by hand.
That stitching is one of the largest points of cost runaway during an outage. In Uptime Institute’s 2025 annual survey, 57% of respondents said their most recent major outage cost more than $100,000. Nobody can start the fix until they know what failed first, so every minute spent reconciling timestamps adds another minute of outage, and the cost keeps climbing.
AI is compounding those stitching difficulties as demand pushes data centers to get bigger, denser, and more distributed, adding three new pressures on the data behind root cause analysis:
- Volume grows with every rack, sensor, and power source a facility adds. Where grid capacity is constrained, operators are adding on-site generation and battery storage, each with its own telemetry stream.
- Velocity rises with throughput. More demand means more hardware to track, more readings to capture, and more usage to bill, while denser AI racks leave less margin for error. Catching a fast-moving cooling issue before it causes real damage requires much tighter intervals between readings.
- Fragmentation comes with building across more sites. Land, power, water, latency, and disaster recovery all push new capacity into new locations. When each site reports its data differently, comparing sites is difficult, and so is consolidating a customer’s usage across them.
Six things to eliminate timeline stitching
When our data center customers described what would have shortened their time to resolution, six things came up consistently.
| Requirement | Where it breaks down today | What an operational telemetry layer provides |
|---|---|---|
| Data frequency | Interval polling in BMS and EPMS can drop the readings that explain a fast-moving event. | Every reading is collected at the frequency the equipment produces it, across mission-critical components. |
| Scale without cost | More sites, racks, and power capacity add more management and a bigger stitching problem. | Predictable costs as sites are added, without a rip-and-replace of existing systems. |
| Reachable data | Analytics, AI, and engineering teams can't easily use data that's already been collected. | One place where every team can query, with secure access designed for enterprise teams. |
| Reliability | Gaps in the record can't be explained to a customer or an incident review. | High availability and read replicas in InfluxDB 3 Enterprise keep the record reliable and queryable through a failure. |
| Reduced dependence | Every question routes through whichever system happens to own the data. | Telemetry in an interoperable data layer runs alongside BMS, EPMS, and DCIM systems. |
| Flexibility | Proprietary formats keep teams reconciling between platforms. | SQL, open APIs, and open formats connect to the tools each team uses today and the ones it adopts next. |
Time ties everything together
Every row in that table comes back to being able to hunt and find out if the server, the cooling unit, or the power feed failed first. The faster your team answers that question, the sooner the fix starts and the outage ends. Each system already timestamps every record, so putting them on one timeline enables a very different workflow.
Building that timeline takes a purpose-built time series foundation that gets four things right:
- High-resolution, real-time data keeps early warnings visible. Downsampling averages readings away, and compressed or delayed data hides the deviations that grow into outages. An 8-second GPU spike past its threshold vanishes into a 1-minute trend.
- No gaps means every reading from every piece of equipment is there when someone has to explain an incident or an invoice.
- Cardinality and context turn readings into an explanation. Metadata on each point, like the asset, its location, and its customer, is what tells the story of an incident. Without it, a team has the numbers but can’t say which equipment or customer they belong to.
- Interoperability puts every system’s readings on one time index, served through SQL and open APIs, without touching facility infrastructure.
From the rack to the fleet
Meeting those four requirements comes down to how each reading travels from the equipment to the people who need it. The diagram below follows one reading from the overheating GPU server at the start of this post, from the rack where it’s collected to a fleet-wide view. The path is the same whether you run colocation, AI infrastructure, or enterprise facilities.
Source Systems
Accelerators
Nodes
PDUs
UPS
CRAH
Chillers
Switches
Optics
Training Jobs
Telegraf
Telegraf collects data from each source using its native protocol
Telegraf Controller
Maintains and manages your agents and configs in a free dashboard
InfluxDB: Enterprise
Organize and measure every rack and its sensors in real time
InfluxDB: Cloud
Cross center comparisons, deeper analysis and total fleetwide awareness
- Every source reports into one timeline. Telegraf, InfluxData’s open source agent, collects from accelerators, PDUs, UPS units, CRAHs, chillers, switches, and training jobs over native protocols. Telegraf Controller manages up to 100 agents and 20 configurations for free, and Telegraf Enterprise runs larger fleets.
- Existing assets and systems become tags. The BMS, EPMS, and DCIM stay in place, and their asset data and hierarchies come into InfluxDB as tags, so every reading arrives already tied to the right asset, location, and customer.
- Each site gets its own real-time record. With every rack and sensor captured in real-time in InfluxDB 3 Enterprise, teams can query recent data for troubleshooting, maintenance, or billing. Deployments include high availability, read replicas, 24/7 support, and SOC 2 Type II, ISO 27001, and ISO 27018 certification. That same full-context history also drives ML and AI training data.
- Benchmark the fleet. InfluxDB Cloud brings data from every site together for cross-facility comparison, deeper root cause analysis, and fleet-wide awareness, so you can compare one site or rack against another with a single query.
Enabling AI-assisted triage
With every site’s readings on one tagged timeline, the first pass of root cause analysis can start from the complete record instead of three screens, and an AI assistant can take that on. The InfluxDB MCP server gives Claude direct access to live telemetry, with no custom middleware to build. As a triage assistant, Claude can help a team diagnose alerts and issues as they occur, understand the cause, and even resolve them, with a clear risk assessment of the proposed solution.
Because the asset, location, and customer arrive already attached as tags, Claude reads power, cooling, and IT telemetry in context and can work out which alarms came first and how severe each one is. To see the same setup yourself, explore the public data center demo.
The RCA telemetry also defends billing disputes
A billing dispute always comes back to the same “what happened and when” question. Proving a charge means showing when power was used and which customer used it. Today, that usually means manually matching a customer’s usage in the DCIM to the power consumption captured in the EPMS—without proper time-stamped data, disputing that claim is difficult.
With DCIM context stored as tags in InfluxDB 3 Enterprise, the usage history behind every invoice is already time-stamped, easily attributed to the right customer, and auditable. A disputed charge gets answered with evidence down to nanosecond precision, pulled from the same record the operations team uses to find the root cause.
Data center operators already running InfluxDB
Colocation providers, AI infrastructure operators, and enterprises running their own facilities around the world already keep their records in InfluxDB, including Stack infrastructure and Data4Group.
The list also includes IBM in AI infrastructure and Kuehne + Nagel, which runs its own facilities for internal workloads. Tthese four operators cover every kind of data center this post set out to help, from colocation providers that answer to many customers, to AI infrastructure running dense GPU racks, and enterprises keeping their own systems up. quipment and scale maydiffer, but the job underneath stays the same. When something fails, each of these teams needs to know what failed first, and with every reading already on one tagged timeline, they have the record to answer that question.
Where to start
Start by adding a trial of InfluxDB 3 Enterprise to an existing site. Pick one site, ideally the one whose last incident review took longest, and use Telegraf to collect its telemetry into InfluxDB 3 Enterprise alongside the BMS, EPMS, and DCIM. The next time a server overheats, the BMS shows a cooling unit failure, and the EPMS shows a power dip, all three events land in one timeline in InfluxDB, already tagged before anyone opens a second screen.
Getting that first site running takes one install command and an email address. On Linux or macOS, install InfluxDB 3 Enterprise with:
curl -O https://www.influxdata.com/d/install_influxdb3.sh && sh install_influxdb3.sh enterprise
Start the server, enter your email when prompted, and choose the trial license. Once you confirm the verification email, your 30-day InfluxDB 3 Enterprise trial is active, and you can point Telegraf at that first site.
Then pull up your last major incident review. Count the systems the team opened to rebuild the timeline, and the hours that passed before everyone agreed on what failed first. The repair waited through every one of those hours while the outage cost kept climbing.
Now picture that same incident in InfluxDB. The overheating GPU server, the failed cooling unit, and the power dip arrive on one timeline in the order they happened, each one already tagged with its asset, location, and customer. Claude reads that record through the InfluxDB MCP server, works out which alarm came first, and proposes a fix with a clear risk assessment. When a customer disputes a charge, the evidence comes from the same history, down to nanosecond precision. As more sites come online, InfluxDB Cloud Solutions brings them together so one query compares any site or rack against the rest of the fleet. Throughout, the BMS, EPMS, and DCIM keep doing the jobs they were built for.
The readings that explain your next outage are already being collected. Give them one timeline in your trial, or see it working first in the public data center demo, and your next incident review begins with what failed first.
