Recipes with the exact ping patterns: exit codes, run duration, output capture, and the grace period that fits each job.WatchFor Team5 min read](/blog/cron-monitoring-recipes)[ReliabilityAug 23, 2026 ## How to read (and write) an SLA report that isn't lying Two companies report 99.95% uptime. One had a flawless month; the other hid a six-hour outage behind measurement tricks. Same number. Here's where SLA reports bend the truth — planned downtime, degraded time, measurement gaps, cherry-picked windows — and what an honest report discloses.WatchFor Team4 min read](/blog/honest-sla-reports)[ReliabilityAug 23, 2026 ## Maintenance windows done right: stop paging yourself for planned work Every team has planned downtime — deploys, migrations, nightly batches. Most handle it by pausing monitors or eating the false alarms. Both are wrong. Here's what a real maintenance window does: silence the noise, keep the data, and keep your SLA honest.WatchFor Team5 min read](/blog/maintenance-windows-done-right)[MonitoringAug 23, 2026 ## Who changed the monitor? Why your monitoring needs an audit trail The postmortem question that has no answer in most monitoring setups: who disabled that alert, when, and what did it look like before? Here's why an audit trail on your monitoring config is as important as one on your production data — for debugging, for teams, and for the SOC 2 auditor.WatchFor Team4 min read](/blog/monitoring-audit-trail)[MonitoringAug 23, 2026 ## Seven API monitors every SaaS should be running (with the exact assertions) Not a philosophy post — a checklist. Seven concrete API monitors, the exact assertion each one needs, and the failure it catches: the lying health endpoint, the silently expiring token, the queue that backs up on Friday night, and four more.WatchFor Team5 min read](/blog/seven-api-monitors-every-saas-needs)[MonitoringAug 23, 2026 ## The complete status page guide: from bare green dots to a page customers actually trust A status page is the most public thing your infrastructure has. This guide covers every layer of building a good one: branding and themes, components and grouping, automatic vs. manual state, third-party dependencies, maintenance announcements, visibility modes, badges and JSON — and the trust rules that make or break all of it.WatchFor Team7 min read](/blog/status-page-complete-guide)[MonitoringAug 23, 2026 ## Webhook reliability: designing deliveries that survive, and monitoring both ends Webhooks fail silently by design — the sender moves on, the receiver never knows what it missed. Here's the engineering playbook for both sides: retries and idempotency, signatures and ordering, dead letters — and the monitoring that catches a dead webhook pipeline before your data drifts.WatchFor Team4 min read](/blog/webhook-reliability-guide)[MonitoringAug 09, 2026 ## API monitoring beyond status codes: assert on the response, chart what matters A 200 OK only proves your API answered — not that the answer was right. Here's why status-only checks miss real outages, what monitoring the response actually takes, and how WatchFor's new API monitor asserts on JSON, extracts values into charts, and pages you when the body goes wrong.WatchFor Team6 min read](/blog/api-monitoring-beyond-status-codes)[ReliabilityJun 26, 2026 ## SLA vs SLO vs SLI: the reliability promise, decoded Three little acronyms quietly run every serious reliability conversation — and almost everyone mixes them up. Here's what SLA, SLO and SLI actually mean, how they fit together, and how to set ones that won't page you at 3am for nothing.WatchFor Team8 min read](/blog/sla-slo-sli)[MonitoringMay 30, 2026 ## What is 99.9% Uptime? The downtime hiding behind the nines “99.9% uptime” sounds almost perfect — until you do the maths. Here's exactly how much downtime each level of nines allows, how it's calculated, and how to pick a target you can actually hit.WatchFor Team3 min read](/blog/what-is-99-9-percent-uptime)[MonitoringMay 23, 2026 ## Website Downtime: the most common causes (and how to prevent each) Most outages aren't mysterious — they come from the same short list of causes, again and again.

Because averages lie. Here's why percentiles like p95 and p99 tell the real story of how your service feels.WatchFor Team3 min read](/blog/latency-percentiles-p99)[MonitoringApr 01, 2026 ## Rate Limiting & HTTP 429 Explained Rate limiting is how services protect themselves from too many requests — and HTTP 429 is how they say 'slow down'. Here's how it works, and how to handle it gracefully on both sides.WatchFor Team3 min read](/blog/rate-limiting-explained)[ReliabilityMar 21, 2026 ## Disaster Recovery: RTO vs RPO explained When the worst happens, two numbers decide how bad it really is: how much data you lose, and how long you're down.

Site Reliability Engineering, explained SRE is what you get when you treat reliability as an engineering problem instead of a firefighting one.
