How to Write a Blameless Postmortem (Small-Team Edition)

The enterprise postmortem template assumes a dedicated SRE org you don't have. Here's a blameless postmortem process built for teams of two to ten: short enough to actually finish, honest enough to fix the real cause, and structured so the same outage never pages you twice.

Landing Page Monitoring: Protect Your Ad Spend

A broken landing page doesn't just lose conversions — it keeps charging you for clicks the whole time it's down. Here's how to monitor the pages your paid traffic lands on, including form submissions and tracking pixels, so a silent break doesn't quietly burn your ad budget.

How to Monitor MCP Servers for Uptime and Reliability

An MCP server is an API your AI agents depend on — and when it goes down, the failure shows up as a vague 'the agent can't do that anymore' instead of a clear outage. Here's how to monitor remote MCP servers for availability, tool-call health, and the transport quirks (SSE, streaming) that standard uptime checks miss.

How to Monitor AI APIs and LLM Features (OpenAI, Anthropic, and Your Own Endpoints)

AI features fail in ways traditional monitoring misses: the provider degrades without going down, rate limits throttle you at peak, streams die mid-response, and latency quietly triples. Here's how to monitor LLM providers and your own AI endpoints so you know before your users do.

Uptime Monitoring vs APM vs Logging: What You Actually Need (and in What Order)

Observability vendors will sell you all three at once. Most teams need them in a specific order: uptime monitoring first, error tracking second, logs third, APM when you have the headcount to act on it. Here's what each layer actually answers, what it costs, and when to add it.

How to Set the Right Timeouts and Response-Time Thresholds for Uptime Monitors

A monitor's timeout is your operational definition of 'down' — and most teams never set it, inheriting a 30-second default that calls a 25-second login page healthy. Here's how to derive timeouts from real baselines, set them per endpoint class, and tune out false positives without going blind.

Uptime Monitoring for Multi-Region Architectures (Active-Active vs Active-Passive)

You deployed to multiple regions so one region's failure wouldn't take you down — but if your monitoring only checks the global endpoint from one place, you can't see a region die, a failover misfire, or a standby that quietly rotted. Here's how to monitor active-active and active-passive architectures properly.

How to Monitor Message Queues (RabbitMQ, SQS, Kafka) for Backlog and Availability

A message queue rarely goes down loudly — the broker stays reachable while a queue quietly backs up, consumers vanish, or messages age past their usefulness. This guide shows how to surface RabbitMQ, SQS, and Kafka health through HTTP endpoints and monitor broker availability, queue depth, and message age externally with CronAlert.

Uptime Monitoring for Multi-Tenant SaaS (Per-Tenant Health)

In a multi-tenant SaaS, 'the app is up' can be true while your biggest customer is completely down — a broken shard, an expired custom-domain certificate, or a failed tenant migration only hits some tenants, and aggregate monitoring averages them away. Here's how to monitor per-tenant health without creating a monitor for every tenant.

How to Monitor Redis and ElastiCache Endpoints

Redis rarely returns a 500 — it just gets slow, runs out of memory, starts evicting keys, or loses a replica, all while your app keeps returning 200. This guide shows how to surface Redis and ElastiCache health through an HTTP endpoint and monitor it externally with CronAlert before a degraded cache becomes an outage.

OAuth and Identity Provider Uptime Monitoring

When your login goes down, everyone is locked out — but your homepage keeps returning 200, so a normal uptime check never notices. This guide shows what to monitor in an OAuth flow and identity provider (Auth0, Okta, Cognito, Google, Entra ID), including JWKS and certificate expiry, and how to watch it all with CronAlert.

How to Monitor Webhook Receivers (Inbound, Not Outbound)

A broken webhook receiver fails silently: Stripe, GitHub, and Twilio keep POSTing, your endpoint keeps 500-ing or timing out, and you lose payments, deploys, and messages with no error on your own dashboards. This guide shows how to monitor the inbound webhook endpoints in your app with CronAlert.

CronAlert vs Freshping: Free Tier and Feature Comparison

Freshping is Freshworks' free uptime monitor — generous on the free tier, but tied to the Freshworks suite and its product roadmap. CronAlert is focused uptime on Cloudflare's edge with a free tier of its own and cheap paid plans. Here's a feature-by-feature comparison, a free-tier-vs-free-tier breakdown, and when each one is the right call.

How to Monitor Postgres Replication Lag

Replication lag is the silent failure that serves stale data, breaks read-after-write consistency, and turns a failover into data loss. This guide shows how to measure Postgres replication lag, expose it through a health endpoint, and monitor it externally with CronAlert.

Uptime Monitoring for Shopify Apps

A Shopify app has more failure surfaces than a normal web app: the embedded admin, the OAuth install flow, webhook receivers, the App Proxy, and Shopify's API rate limits. When any of them goes down, merchants churn and your listing is at risk. This guide covers what to monitor and how.

Background workers fail silently because nobody is watching them. Web servers throw obvious errors when they go down; queue consumers just stop draining the queue, jobs back up, and customers notice hours later. Here's how to monitor background workers and queue consumers — Sidekiq, Celery, BullMQ, RabbitMQ consumers, SQS workers — with heartbeats, queue-depth checks, and lag monitoring.

Uptime Monitoring for Nonprofits and Education: FERPA, Donor Portals, and LMS Reliability

Nonprofits and educational institutions run mission-critical systems on small budgets and smaller IT teams — donor portals, learning management systems, financial-aid applications, student information systems. Downtime costs donations, blocks coursework, and erodes trust. Here's how to monitor uptime cost-effectively, stay aligned with FERPA, and protect the systems your community depends on.

How to Monitor gRPC Endpoints for Uptime and Errors

gRPC endpoints fail in ways HTTP monitors cannot see — every framing is HTTP/2, errors live in trailers, and a healthy TCP connection can still be returning UNAVAILABLE on every call. Here's how to monitor gRPC services correctly: health-check protocol, streaming RPCs, TLS, and how to wire it into a normal uptime monitoring setup.

CronAlert vs Healthchecks.io: Heartbeat Monitoring and the Full Uptime Picture

Healthchecks.io is a focused heartbeat monitor for cron jobs and background tasks. CronAlert covers the same ground plus URL uptime, content monitoring, SSL, and status pages. Here's how the two compare on heartbeat features, pricing, and when a single tool actually wins.

How to Monitor WebSocket and Real-Time Endpoints for Uptime

WebSocket connections fail in ways HTTP monitors cannot see — the upgrade handshake succeeds, then the connection silently dies, drops messages, or stalls. Here's how to monitor WebSocket endpoints for uptime, latency, and message delivery without building a custom monitoring system from scratch.

CronAlert vs Pingdom: A Modern Alternative to a Legacy Tool

Pingdom is one of the oldest names in uptime monitoring, but its pricing, feature pacing, and ownership history have left teams looking for alternatives. Here's a feature-by-feature comparison of CronAlert vs Pingdom — what each does well, what they charge, and when to choose each.

Uptime Monitoring for Fintech: PCI-DSS, SOC 2, and Payment Reliability

Fintech systems can't fail silently — every minute of payment downtime is a regulatory event, a chargeback risk, and a customer-trust event. Here's how to monitor fintech apps in line with PCI-DSS and SOC 2, what to log (and what to never log), and how to keep monitoring vendors out of cardholder scope.

DNS Monitoring: Catch Resolution Failures, Propagation Delays, and Hijacks

DNS is the invisible failure mode behind a lot of 'site is down' incidents that aren't actually about the site. Here's how to monitor DNS for resolution failures, propagation delays, expiring records, and hijacks — and how to wire DNS checks into a normal HTTP uptime monitoring setup.

Uptime Monitoring for Healthcare and HIPAA Compliance

Healthcare apps have stricter uptime requirements than most SaaS — patient portals, EHR integrations, and telehealth platforms can't fail silently. Here's how to monitor healthcare systems without violating HIPAA, what to log, and how to handle BAAs with monitoring vendors.

How to Read and Use Uptime Reports (Without Drowning in Numbers)

Uptime reports are full of percentages, response times, and incident counts that look meaningful but rarely change behavior. Here's how to read uptime reports, what to ignore, what to act on, and how to turn the numbers into engineering decisions.

How to Monitor Your Staging Environment (and Why It Matters More Than You Think)

Staging environments break silently because nobody is watching. When staging is down, deploys get blocked, integrations stop testing, and engineers waste hours chasing ghosts. Here's how to monitor staging without paging anyone at 3am.

Uptime Monitoring for Mobile App Backends (iOS, Android, React Native)

Mobile app outages look different from web outages — users can't refresh, error states are buried in the app, and a backend regression takes weeks to roll back through the App Store. Here's how to monitor mobile app backends so you find problems before your users do.

How CronAlert's Edge Network Reduces False Positive Alerts

False positives train you to ignore real alerts. See how consecutive-check verification, multi-region quorum, and Cloudflare's edge network keep CronAlert alerts trustworthy.
