DevOps Monitoring

Catch infrastructure problems before your users do

NotiLens monitors CPU trends, disk growth, deploy failures, and health check silence — giving your team the lead time to act before an incident becomes an outage.

Trend Alert — server

"CPU spike detected — jumped to 72%, more than 2× above your normal baseline."

Your server CPU spiked after a traffic surge. NotiLens detected the anomaly against your normal baseline and fired immediately — giving your team time to scale before users started timing out.

server-metrics · Spike Alert · 72% · 2× above baseline

Silence Alert — deploy

"No deploy events in 48 hours — pipeline may be broken."

Your team ships daily. Two days of silence from the deploy topic meant either the pipeline was broken or all changes were being blocked. NotiLens caught it before a broken branch sat undeployed through the weekend.

Trend Alert — disk

"Disk at 93% and growing 2% per day — full in ~3 days."

Log rotation failed silently. Disk crept up 2% per day and no threshold alert fired because it hadn't hit 95% yet. NotiLens projected it would in three days — enough time to fix log rotation before the database crashed.

Silence Alert — health check

"api-service stopped sending heartbeats — 12 minutes ago."

Your API service was supposed to ping a NotiLens topic every minute. After 5 missed pings, NotiLens fired. The container had OOM-crashed and auto-restart had silently failed. No error logs, no alerts — until NotiLens noticed the silence.

Rate Anomaly — errors

"Error rate 4× baseline — spiked 3 minutes after deploy."

A bad migration was deployed to production. Error events spiked immediately after the deploy event landed in NotiLens. The correlation was automatic — your team got an alert with the deploy timestamp and the error rate, and rolled back within 4 minutes.

Silence Alert — deploy

"Deploy failed silently at 3am — users on broken version for 6 hours."

GitHub Actions exited non-zero at 3am. The deploy didn't happen. No one was watching. Six hours later, at standup, someone noticed the version mismatch. A NotiLens silence alert on the deploy topic would have fired at 3:05am.

The Problem

Infrastructure problems give you warnings. Are you listening?

Most outages don't come from nowhere — they build slowly. CPU trending up. Disk quietly filling. A deploy that never confirmed success. The signals were there; nobody was watching.

CPU trending to 95% unnoticed

Your server CPU crept from 40% to 92% over three hours. No threshold alert fired because you'd set it to 95%. By the time it hit 95%, users were already timing out.

Deploy silently failed

The GitHub Actions workflow exited with a non-zero code at 3am. The deploy didn't happen. Users were on a broken version for 6 hours before anyone checked the pipeline.

Disk full overnight

Log rotation wasn't working. Disk usage grew 2% per day unnoticed. At 100%, the database crashed. The fix took 20 minutes — the outage lasted 4 hours.

How NotiLens Helps

Trend-aware monitoring for DevOps teams

NotiLens doesn't just watch thresholds — it tracks trends, detects silence, and projects where your metrics are heading, giving you time to intervene.

Server metric anomaly detection

NotiLens learns what normal looks like for CPU, memory, and disk on your servers. When a metric deviates significantly from its baseline, you get an alert — before it becomes an outage.

Deploy event monitoring

Track deploy events from GitHub Actions, CI pipelines, or custom scripts. Get alerted if a deploy fails, hangs, or if no deploy has landed in an unexpectedly long time.

Health check silence detection

Set a heartbeat cadence for your services. If a health check event stops arriving within your defined window, NotiLens fires an alert — even if nothing is actively erroring.

Error rate spike after deploy

Forward error events to NotiLens. When errors spike within minutes of a deploy event, NotiLens correlates them and alerts your team — so you can roll back before the incident compounds.

On-call routing & ACK

Route infrastructure alerts to the right team channel — server metrics to ops, deploy failures to eng, disk alerts to platform. Critical alerts repeat until someone acknowledges them.

Silence window scheduling

Set maintenance windows so planned restarts and scheduled downtime don't fire false alerts. NotiLens resumes alerting automatically when the window closes.

Real Alerts

What NotiLens sends your on-call team

Actionable alerts with projection data — so you know not just what's happening, but what's about to happen.

A quiet pipeline is not a healthy pipeline.

If your deploy events stop arriving, NotiLens tells you. If your health checks go silent, NotiLens tells you. Most monitoring tools can't detect silence — NotiLens is built around it.

FAQ

Common questions

How is NotiLens different from Datadog or New Relic? +

Datadog and New Relic are full observability platforms — metrics, logs, traces, dashboards. NotiLens is focused on alerting: it detects when something breaks or goes silent and tells the right person immediately. It's not a replacement for observability tooling — it's what wakes you up when your existing tools didn't.

My infra already has monitoring. Why add NotiLens? +

Most monitoring tools alert on thresholds you set in advance. They miss slow trends (disk growing 2%/day) and silence events (a service that stops sending data entirely). NotiLens specialises in exactly these gaps — trend projection and silence detection — and delivers alerts before your existing tools would have fired.

How does trend projection work? +

NotiLens calculates the rate of change for a metric over a rolling window and projects when it will cross your threshold. So instead of alerting at 95% CPU, it tells you "CPU is at 72% and will reach 95% in approximately 8 minutes" — giving your team time to act before it's a crisis.

Can I route different alerts to different teams? +

Yes. Each NotiLens topic can route to a different team member or group through the NotiLens mobile app. Server metrics go to ops, deploy failures go to engineering, disk alerts go to the platform team. Critical alerts use ACK (acknowledgement), which re-notifies every 5 minutes until someone confirms they're handling it.
