How each platform builds operational context

Selector collects raw telemetry and operational context together from every vendor, normalizes and enriches it before any model runs, and establishes causation with purpose-built ML before agents act. A typical DIY approach combines open-source and cloud components, such as Telegraf or gNMIc collectors, Kafka, Prometheus or InfluxDB, OpenSearch or Elasticsearch, Grafana, custom Python correlation logic, and LLM APIs, integrated and maintained by an internal team.

Foundry agents

Rosetta, Loom, TicketMaster, Artist, Herald, Sculptor; MCP and A2A.

Collaboration

Natural language, dashboards, ChatOps, ITSM workflows, query-backed APIs.

Knowledge

Anomaly detection, correlation, causation, forecasting, knowledge graph.

Data Hypervisor

ML schema inference, enrichment, ELT raw preservation, routing.

Collection

Horizontal engines near the source; push and pull; independent scaling.

Sources

Any vendor’s devices, cloud, CMDB, IPAM, ITSM, tools, and files.

LLM scripts

Custom agents or chat interfaces built on LLM APIs.

Dashboards and alerts

Grafana dashboards and Alertmanager rules.

Custom correlation

Python rules, scripts, and models written in-house.

Data stores

Prometheus, InfluxDB, OpenSearch, and Kafka.

Collectors

Telegraf, gNMIc, Logstash, flow collectors, custom scripts.

Sources

Whatever the team integrates and keeps working.

Where a DIY stack falls short architecturally:

Every layer is the team’s to build and maintain: Collection, normalization, storage, correlation, and agents each need engineering, upgrades, and on-call ownership. Selector delivers all of them as one maintained platform.

Causation is the hardest part to build: Dashboards and alert rules are straightforward; deterministic, topology-aware causation across vendors is not. Selector’s patented models deliver it.

LLM-first shortcuts are fragile: LLM scripts over raw data can hallucinate and give different answers to the same question. Selector uses LLMs only to explain deterministic findings.

Use case 1: Observability

Multivendor data collection

Open-source collectors can gather most data types, but each needs integration and upkeep. Selector collects everything into one pipeline as a maintained product.

Data type
DIY Stack
Metrics
Telegraf, gNMIc, and exporters; each integration built and maintained in-house.
SNMP, gNMI and model-driven streaming telemetry, Prometheus-compatible sources, REST APIs.
Logs
Logstash or Fluent Bit with authored parsers.
Syslog from any device, infrastructure, or application, structured by ML; Splunk, Logstash, TACACS.
Flow
Open-source flow collectors such as pmacct or GoFlow.
NetFlow, sFlow, IPFIX from devices or collectors, enriched with application, owner, and criticality.
Routing
BMP collectors such as OpenBMP, integrated in-house.
BGP, BMP/OBMP, and IGP state ingested from customer devices.
Configuration
Oxidized or scripts for backups. Drift correlated with impact must be built.
Running and intended config via NETCONF and CLI; drift correlated with impact.
Topology
Topology modeling must be built.
From SNMP, CDP/LLDP, configuration, and telemetry, across all vendors; digital twin.
Context
Custom CMDB and NetBox integrations.
ServiceNow CMDB, NetBox, Nautobot, Infoblox; owner, site, circuit, criticality.
Hybrid & multicloud
Cloud exporters and APIs per provider.
AWS, Azure, Google Cloud APIs, flow logs, transit gateways, VPCs, correlated with on-prem.
Digital experience
Blackbox exporters and custom probes.
ICMP and UDP probes, ThousandEyes, traceroute, custom tests.
Files / streams
Kafka and scripts.
Kafka, CSV, Excel, Google Sheets.

DIY gaps

Every collector, integration, and upgrade is owned by the internal team.

Topology and dependency modeling must be built from scratch.

Coverage drifts as vendors, firmware, and APIs change.

Selector value

Streaming telemetry, flow, routing, configuration, and context from any vendor in one pipeline.

Routing changes tied to the services they affect, from BMP and IGP state on the customer’s own devices.

Ingestion from files and streams for data with no API.

Use case 1: Observability

Data normalization and enrichment

Selector normalizes and enriches every signal before any model runs. In a DIY stack, every parser, schema, and enrichment rule is written and maintained by the team.

Capability
DIY Stack
Data Hypervisor
Schema inference
Hand-written parsers per source.
ML infers structure from free-form logs, syslog, traps, and CLI output; no parsing templates.
Entity resolution
Must be built.
Named-entity and clustering models group events across vendor and format variations.
Enrichment
Custom enrichment scripts.
Topology, dependency, owner, site, maintenance state, and criticality added before analysis.
Data fidelity
Depends on storage design and retention budget.
ELT: raw data lands with original timestamps; transformation follows.
Noise suppression
Alertmanager rules and inhibition.
Duplicate, flapping, and irrelevant signals removed before the intelligence layer.
Business logic
Rules files and scripts.
Maintenance windows, provider notices, suppression, and criticality in YAML via DevOps workflows.
Customization
Unlimited, at the cost of engineering time.
S2ML tunes enrichment, labeling, noise rules, prioritization, and LLM output.
Data access
Multiple query languages across stores.
Every view is a query and can be exposed as an API endpoint; MCP server.

DIY gaps

Parsers, schemas, and enrichment logic are written and maintained by hand.

Data spreads across several stores with different query languages.

Raw-data replay of network state must be designed and built.

Selector value

Learned normalization: no parsing templates or rules to maintain.

Raw records retained with original timestamps for replay and re-analysis.

One enrichment layer applies topology, ownership, maintenance, and criticality to every signal.

Use case 1: Observability

AI-powered operational analytics

Selector models every time series individually and correlates across domains automatically. A DIY stack starts with thresholds and requires custom data science for anything more.

Capability
DIY Stack
Anomaly detection
Static thresholds or custom models.
Self-supervised, statistical, and regression models. A model per time series, retrained every 30 minutes, with seasonality.
Log analysis
Search and authored rules.
Small language models. Log semantics interpreted, clustered across vendors, and turned into structured events.
Prediction
Requires custom models.
Forecasting and predictive models. Capacity forecasting and optical transceiver failure prediction.
Cross-domain analysis
Requires custom correlation logic.
One model across domains. Correlation runs automatically across network, cloud, and application signals.
Natural language
LLM scripts over data, built in-house.
Rosetta. Plain-language questions answered with every claim linked to source data.

DIY gaps

Anomaly detection must be built, tuned, and retrained.

Cross-domain correlation requires custom models.

Prediction requires data science investment.

Selector value

Per-series models retrained every 30 minutes detect anomalies no threshold would catch.

Automatic correlation across network, cloud, and application signals in one model.

Optical failure prediction and capacity forecasting before impact.

Use case 2: Event intelligence

Event correlation and root cause

Correlation and causation are the hardest parts of a DIY stack. Selector delivers deterministic, topology-aware causation as a product.
Capability
DIY Stack
Inputs
Alerts from Alertmanager and other tools.
Alerts and the raw telemetry, logs, flow, and configuration behind them, correlated together.
Correlation method
Rules and scripts written in-house.
Contextual embeddings and clustering by shared devices, interfaces, IP addresses, topology, and time.
Noise reduction
Inhibition rules and deduplication.
Up to 99.9% of irrelevant noise removed before correlation.
Root cause
Requires building causal models.
Deterministic causation from topology and domain logic: reboot, then link failure, then BGP flap.
Symptom vs. cause
Must be engineered.
Downstream effects labeled as consequences, not separate faults, across every domain.
Change correlation
Must be built.
Configuration diffs and change events correlated directly with degradation.
Evidence and replay
Depends on in-house design.
Every finding links to source data; Network DVR replays past network state.

Selector example

The Loom agent resolved 214 alerts across six tools to a single fiber cut on one long-haul span, labeled routing reconvergence and cloud failover as consequences, and flagged the secondary path at 78% utilization as the next risk.

The DIY reality

A Grafana alert storm during a fiber cut produces many alerts with no named cause. Building logic that names the cut and labels the rest takes sustained engineering.

DIY gaps

Correlation is rules and scripts unless causal models are built.

Symptom-versus-cause labeling must be engineered.

LLM-based analysis can return different answers for the same data.

Selector value

Alert floods collapse into one incident with a named cause, consequences, and next risk.

Telemetry, logs, flow, and configuration correlated with alerts in one model.

Every finding is traceable and reproducible with Network DVR.

Selector value

Sculptor builds governed agents from the team’s own playbooks, acting only on verified findings.

MCP server shares insights and governed actions with other agent platforms.

Every Foundry agent is available now, in every deployment model.

Functionality gained with Selector

Capabilities a team gets on day one with Selector instead of building and maintaining them in-house.

1. One maintained platform

Collection, normalization, storage, correlation, and agents delivered and maintained as one product, instead of a stack the team must own.

2. Deterministic diagnosis

Root cause comes from deterministic topology and domain models, so the same data yields the same answer.

3. Detection beyond thresholds

Per-series models retrained every 30 minutes find conditions no static threshold or rule would catch.

4. Streaming and routing depth

gNMI streaming telemetry and BMP/OBMP and IGP analytics from the customer’s own devices, plus optical failure prediction.

5. Full-fidelity history

Raw data preserved with original timestamps; Network DVR replays past network state so findings can be verified and re-run.

6. No templates to maintain

Learned normalization infers structure across vendors and formats, replacing hand-written parsers and enrichment scripts.

7. Your playbooks as agents

Sculptor turns the team’s own runbooks into governed agents with approved tools, triggers, approval points, and audit.

8. Governed action through MCP

Selector’s MCP server exposes insights, recommendations, and actions to other agent platforms under OAuth2 and RBAC.

9. Custom outcomes with engineers

Forward deployed engineers build integrations, data models, views, and agents on the customer’s own data.

10. Reuse what you have

Selector ingests from existing collectors, Kafka, Prometheus, and InfluxDB, so prior DIY investment carries forward.

The bottom line

Building in-house gives full control and works well for dashboards and alerting, but collection upkeep, normalization, correlation, causation, and agent governance become long-term engineering commitments.

Selector delivers those capabilities as a maintained platform, with patented causation, raw-data replay, governed agents, and forward deployed engineers, so the team spends its time operating the network instead of building tools.
