Stack Monitor

Stack Monitor tracks the real-time status of hosted SaaS and developer tools, helping you stay ahead of outages and claim SLA credits when services fail to meet their uptime guarantees.

Features

Real-Time Uptime Monitoring

We continuously monitor the status of popular developer tools and SaaS services, checking every 5 minutes. When an outage is detected, we require 3 consecutive failures to confirm it's a real incident (not a transient blip).

Incident History

View detailed incident history for any tool, including:

• Start time - When the outage began
• Duration - How long the service was down
• Severity - Minor (degraded), Major (partial outage), or Critical (full outage)
• Status - Investigating, Identified, Monitoring, or Resolved

SLA Violation Detection

Stack Monitor automatically calculates uptime percentages and flags when tools fall below their published SLA targets. Most enterprise SaaS tools guarantee 99.9% or higher uptime - we help you track whether they're meeting that promise.

SLA Credit Claims

When a tool violates its SLA, you may be entitled to service credits. Stack Monitor helps you:

1. Identify violations - See which tools missed their uptime targets
2. Calculate credit amounts - Estimate credits based on severity and duration
3. Document incidents - Export incident data for your credit claim

How We Monitor

Stack Monitor uses multiple strategies to detect outages:

Confirmation Logic

To avoid false positives from transient network issues:

• Creating incidents: Requires 3 consecutive failures (2 seconds apart)
• Resolving incidents: Requires 2 consecutive successes (2 seconds apart)

This means real outages are confirmed within ~15 minutes while brief glitches are filtered out.
