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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.

UptimeRobot alerts for outages that never happened? Here's why UptimeRobot false positives happen — single-region checks, no consecutive retry defaults, WAF conflicts — and how to stop them.
GraphQL endpoints fail in ways REST monitors cannot detect — every response is a 200 OK, errors live in the body, and a single POST exposes hundreds of query paths. Here's how to monitor GraphQL APIs correctly.
Next.js on Vercel has specific failure modes — cold starts on Serverless Functions, ISR revalidation bugs, Edge runtime limits, misrouted middleware. Here's what to monitor and how to catch outages before users do.
Most outages come from the same ten causes: DNS, expired certs, deploy bugs, database overload, third-party dependencies, DDoS, cache misconfigurations, domain expiry, hosting issues, and traffic spikes. Here's how to prevent each.
Email is the universal fallback channel for uptime alerts — every team has it, every tool supports it. But it has latency, deliverability, and noise problems. Here's how to set up email alerts correctly and when to use email versus other channels.

Reporting tells you whether you hit your SLA last quarter. Compliance tells you whether you'll hit it next quarter. This guide walks through using CronAlert uptime data proactively — error budgets, SLO burn rate, per-customer SLAs, maintenance window policy, and the operational habits that turn monitoring data into reliability decisions.
Site24x7 is ManageEngine's all-in-one monitoring suite — uptime, APM, server, network, log, and cloud monitoring under one bundle. CronAlert is focused uptime on Cloudflare's edge. If you only need uptime, the bundled pricing and configuration overhead of Site24x7 is hard to justify. Here's a feature-by-feature comparison and when each one is the right call.

Long-running batch jobs — nightly ETL, dbt runs, Airflow DAGs, Spark jobs, large data exports — fail in ways short cron heartbeats can't detect. Here's how to monitor batch jobs that run for hours or days: start/finish pings, max-duration alerts, milestone monitoring, and partial-failure detection.
Server-Sent Events stream over plain HTTP but fail in ways simple HTTP monitors miss — proxies buffer the stream, connections die mid-stream, events stall while the TCP connection looks healthy. Here's how to monitor SSE endpoints for uptime, delivery, and latency with the tools you already have.
StatusCake has been around for over a decade and is one of the most familiar uptime monitoring brands. CronAlert covers the same monitoring surface — HTTP, SSL, keyword, domain, and team monitoring — at roughly one-fifth the cost, on Cloudflare's edge, with multi-region quorum included. Here's a feature-by-feature comparison.
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.
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.
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.
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.
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.
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.
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 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.
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.
Route CronAlert downtime alerts to Opsgenie for on-call escalation, deduplication, and 24/7 paging. Set up the integration via webhook, map the payload, and test the flow end-to-end.
A practical guide to HTTP health check endpoints: shallow vs deep checks, /healthz vs /readyz vs /livez, what to include and exclude, code examples for Node.js, Python, Go, and Rust, and how Kubernetes liveness and readiness probes differ from external uptime checks.
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.
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.
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.
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.
