Implementing AIOps for IT Operations Automation

Monitoring based on static thresholds drowns in false alerts, while manual event correlation consumes hours. We implement AIOps—an approach using machine learning to analyze metrics, logs, events, and alerts. The goal is not to replace engineers but to reduce alert fatigue, detect anomalies before incidents occur, and automatically correlate events from different sources into a single picture. Experience shows that after AIOps adoption, alert volume decreases by 70% and MTTR drops by 3–5x.

The gap between theory and practice is especially wide here. “Implementing AIOps” may sound like buying a product. In reality, it’s a multi-month effort to build a data pipeline from metrics, train baseline models, tune thresholds, and integrate with incident management. We ensure your team gets not just a tool but a working system adapted to your infrastructure.

What AIOps Solves That Traditional Monitoring Cannot

AIOps is not just a trend—it’s a necessity for large infrastructures. Prometheus with alert rules relies on static thresholds: cpu > 80%. The problem: normal CPU on Monday morning is 70%, while Sunday night it’s 10%. An alert at 80% is either false (at night) or too late (on Monday, CPU may already be 90% when the alert fires).

Anomaly detection looks not at absolute values but at deviation from a seasonal baseline. If CPU is usually 70% on Monday at 10:00, but today it’s 40%—that’s also an anomaly (the service may have stopped receiving traffic). Anomaly detection is 50% more accurate than static thresholds.

The second task is noise reduction. In a large infrastructure, a single incident triggers 50–200 alerts: database unreachable → all services depending on it also alert → monitoring of those services alerts too. Event correlation groups them into one incident with a root cause.

How We Implement AIOps in Your Existing Infrastructure

Implementation begins with an audit of your current monitoring: which metrics are collected, which alerts are configured, and how the incident management process works. Then we design the data pipeline and select appropriate ML models.

Prometheus + Grafana ML Anomaly Detection

Grafana with Prophet-based forecasting via the Grafana ML plugin:

---
# Grafana datasource for ML-processed metrics
apiVersion: 1
datasources:
  - name: Grafana ML
    type: grafana-ml-datasource
    url: http://grafana-ml:3000
    jsonData:
      prometheusUrl: http://prometheus:9090

For Prometheus—metricbeat with ML jobs or VictoriaMetrics Anomaly Detection:

---
# VictoriaMetrics anomaly detection config
schedulers:
  periodic:
    class: "scheduler.periodic.PeriodicScheduler"
    infer_every: "1m"
    fit_every: "1h"
    fit_window: "14d"
    models:
      zscore:
        class: "model.zscore.ZscoreModel"
        z_threshold: 2.5
      prophet:
        class: "model.prophet.ProphetModel"
        args:
          changepoint_prior_scale: 0.05
          seasonality_mode: "multiplicative"
          yearly_seasonality: false
          weekly_seasonality: true
          daily_seasonality: true
    queries:
      cpu_usage:
        expr: "avg by (instance) (rate(node_cpu_seconds_total{mode!='idle'}[5m]))"
        step: "1m"
        model: "prophet"
      error_rate:
        expr: "rate(http_requests_total{status=~'5..'}[5m])"
        step: "1m"
        model: "zscore"

Result: an anomaly_score metric from 0 to 1. An alert fires when anomaly_score > 0.8, not when cpu > 80%. This reduces MTTR by 3x compared to manual correlation.

Alert Correlation with Moogsoft / BigPanda / Custom Code

Commercial AIOps platforms (Moogsoft, BigPanda) ingest alerts from Prometheus, PagerDuty, ServiceNow and correlate them via ML. For those who prefer open-source, we build custom correlation logic.

A simple correlation: group alerts by time window and common labels:

from collections import defaultdict
from datetime import datetime, timedelta

def correlate_alerts(alerts: list[dict], window_minutes: int = 5) -> list[dict]:
    """Groups alerts occurring within the same time window."""
    incidents = []
    used = set()
    for i, alert in enumerate(alerts):
        if i in used:
            continue
        group = [alert]
        alert_time = datetime.fromisoformat(alert['startsAt'])
        for j, other in enumerate(alerts[i+1:], i+1):
            if j in used:
                continue
            other_time = datetime.fromisoformat(other['startsAt'])
            # Alert in the same time window
            if abs((other_time - alert_time).total_seconds()) < window_minutes * 60:
                # And in the same namespace or on the same node
                if (alert['labels'].get('namespace') == other['labels'].get('namespace') or
                        alert['labels'].get('node') == other['labels'].get('node')):
                    group.append(other)
                    used.add(j)
        if len(group) > 1:
            incidents.append({
                "type": "correlated_incident",
                "root_cause_candidate": min(group, key=lambda a: a['startsAt']),
                "related_alerts": group[1:],
                "alert_count": len(group),
            })
        else:
            incidents.append({"type": "single_alert", **alert})
    return incidents

The first alert in the group is a candidate for root cause. It’s not exact, but gives the engineer a correct starting point.

Log Anomaly Detection with OpenSearch / Elasticsearch

OpenSearch ML Commons provides built-in anomaly detection for logs:

PUT _plugins/_anomaly_detection/detectors
{
  "name": "error-rate-detector",
  "description": "Detect anomalies in error log rate",
  "time_field": "@timestamp",
  "indices": ["app-logs-*"],
  "feature_attributes": [
    {
      "feature_name": "error_count",
      "feature_enabled": true,
      "aggregation_query": {
        "error_count": {
          "value_count": {
            "field": "level",
            "script": {
              "source": "doc['level.keyword'].value == 'ERROR' ? 1 : 0"
            }
          }
        }
      }
    }
  ],
  "detection_interval": {
    "period": {
      "interval": 5,
      "unit": "Minutes"
    }
  },
  "window_delay": {
    "period": {
      "interval": 1,
      "unit": "Minutes"
    }
  }
}

The detector learns from 14 days of historical data and then flags anomalous error spikes before they reach SLO thresholds.

LLM for Incident Summarization

GPT-4 or a local LLM (LLaMA via Ollama) for summarizing incidents from logs and metrics:

import openai
from datetime import datetime, timedelta

def summarize_incident(prometheus_url: str, incident_start: datetime):
    # Collect metrics for the incident period
    metrics = fetch_prometheus_metrics(prometheus_url, incident_start)
    logs = fetch_logs_from_loki(incident_start, incident_start + timedelta(hours=1))
    prompt = f"""You are a DevOps SRE. Analyze the following metrics and logs from a production incident and provide:
1. Root cause hypothesis
2. Affected services
3. Timeline of events
4. Recommended immediate actions

Metrics (last 30 min): {metrics}
Relevant log entries: {logs[:3000]}
Respond in Russian."""
    response = openai.chat.completions.create(
        model="gpt-4-turbo",
        messages=[{"role": "user", "content": prompt}],
        max_tokens=1000,
    )
    return response.choices[0].message.content

The result is sent to Slack when an incident is created—engineers get a structured summary instead of 200 lines of alerts.
