Monitoring Architecture
Multiple globally distributed probes check your endpoints and report results to Bleemeo Cloud for correlation and alerting.
Globally Distributed Probes
Bleemeo operates 7 probe locations across 3 continents. By default, European monitors use 3 EU probes (Frankfurt, Milan, Paris), but you can select any combination of locations per monitor. Each probe independently checks your endpoint every 60 seconds and records availability, response time, HTTP status code, and TLS certificate details. Selecting probes close to your user base ensures you measure the experience your actual customers have.
Private Probes for Internal Monitoring
Any Glouton agent installed on your infrastructure can act as a private uptime probe. This extends monitoring to services behind firewalls, VPNs, and internal networks — staging environments, intranet applications, internal APIs, and pre-production systems. Private probes run the same check protocols (HTTP, TCP, DNS, ICMP) at the same 60-second intervals as public probes. There is no limit on the number of private probes per account.
Advanced Content Validation
Beyond simple status code checks, Bleemeo validates response content to catch silent failures. Configure "text must be present" rules to verify that a page contains expected content (e.g., a product name or API version string). Configure "text must be absent" rules to detect error pages that return HTTP 200 (e.g., a maintenance page). For advanced scenarios, custom Blackbox Exporter modules support TLS version enforcement, HTTP basic auth, bearer tokens, and custom request headers.
Per-Location Response Time Analysis
Every check records response time from each probe location independently. Compare latency across regions to detect CDN misconfigurations, DNS propagation delays, or regional backend performance issues. If your Frankfurt probe shows 50ms latency while your Singapore probe shows 2 seconds, you immediately know there is a routing or CDN issue affecting Asian users — without waiting for user reports.

What Is Uptime Monitoring?
Uptime monitoring is the practice of continuously checking whether your websites, APIs, and online services are available and responding correctly to user requests. It involves sending automated checks from multiple geographic locations at regular intervals and alerting your team the moment a service becomes unreachable or starts behaving abnormally.
Downtime is expensive. Studies estimate that the average cost of IT downtime ranges from $5,600 to over $9,000 per minute for enterprise organizations. Even for smaller businesses, an outage during peak traffic can mean lost sales, frustrated customers, and long-term damage to brand reputation. Beyond revenue, downtime erodes customer trust — users who encounter repeated outages will switch to competitors without warning.
For organizations with Service Level Agreements (SLAs), uptime monitoring is not optional — it is a contractual obligation. An SLA promising 99.9% availability allows only 8 hours and 45 minutes of downtime per year. Without continuous monitoring, you cannot prove compliance, detect violations early, or respond before penalties apply. Bleemeo's uptime monitoring gives you sub-minute detection, multi-location verification, and historical SLA reports to keep your commitments on track.
How Bleemeo Uptime Monitoring Works
Configure Your Monitors
Add the URLs, IPs, or hostnames you want to monitor. Choose the protocol (HTTP/HTTPS, TCP, DNS, or ICMP), select your monitoring locations, and optionally configure advanced validation rules such as expected response codes, body content checks, or custom HTTP headers for API authentication.
Probes Check Every 60 seconds
From each selected location, Bleemeo sends a check to your endpoint every 60 seconds. Each check records whether the service responded, the HTTP status code, response time in milliseconds, and whether any validation rules passed or failed. SSL certificate expiration and domain WHOIS data are also collected automatically for HTTPS monitors.
Majority-Vote Prevents False Positives
A single failed check from one location does not trigger an alert. Bleemeo uses a majority-vote algorithm: an alert is raised only when the majority of your selected probes report a failure simultaneously. This eliminates false positives caused by transient network routing issues, regional DNS propagation delays, or a single probe's connectivity blip.
Instant Alert Notification
When a real outage is confirmed, Bleemeo immediately sends notifications through your configured channels — email, SMS, webhooks, Slack, PagerDuty, OpsGenie, or Microsoft Teams. The alert includes the affected monitor, the failing locations, the error type, and response details so your on-call team has actionable context from the first notification.
Dashboard and Historical Analysis
The Bleemeo dashboard shows real-time status, response time graphs per location, and historical availability percentages. You can compare latency across geographic regions, identify performance degradation trends, and generate SLA compliance reports for stakeholders. All data is retained for long-term trend analysis and capacity planning.

Advanced Capabilities
Private Probes
Use any Glouton agent installed on your servers as a monitoring probe. Monitor internal APIs, staging environments, intranet applications, and services behind firewalls that are not accessible from the public internet. Private probes run the same checks as public probes — same protocols, same validation rules, same 30-second intervals — but from inside your network. You can have unlimited private probes connected to your account.
SSL & Domain Expiration Tracking
For every HTTPS monitor, Bleemeo automatically tracks SSL certificate expiration. You receive a warning alert 20 days before expiration and a critical alert 10 days before. Domain name expiration is also monitored via WHOIS lookups with the same 20/10 day thresholds. This dual tracking ensures you never let a certificate or domain lapse — a surprisingly common cause of outages that is entirely preventable with automated monitoring.
HTTP Content Validation
A 200 OK status code does not always mean your service is healthy — error pages, maintenance pages, and degraded responses can all return 200. Bleemeo lets you validate the response body: specify text that must be present (e.g., a version string or a specific JSON field) and text that must be absent (e.g., "error", "maintenance"). This ensures your checks verify actual functionality, not just reachability.
Use Cases
E-Commerce Platforms
Monitor product pages, checkout flows, and payment gateway endpoints. Detect outages during flash sales or holiday traffic peaks before they cost revenue. Track response times to ensure fast page loads that reduce cart abandonment.
SaaS Applications
Monitor API endpoints, login pages, and webhook delivery. Verify that authentication services respond correctly and that API rate limits are not silently failing. Generate uptime reports to satisfy enterprise customer SLA requirements.
Internal Tools & Staging
Use private probes to monitor internal dashboards, staging environments, and pre-production APIs. Detect issues in staging before they reach production. Verify that internal services like CI/CD, wikis, and ticketing systems are available for your team.
Staging & Pre-Production
Catch deployment-related regressions by monitoring staging environments alongside production. Compare response times across environments and detect configuration drift that might cause production incidents after the next release.
DNS Health Monitoring
Monitor DNS resolution from multiple locations to detect propagation issues, NXDOMAIN responses, and incorrect record values. Ensure your domain resolves correctly worldwide — especially important during DNS migrations or CDN changes.
SSL Certificate Management
Track SSL certificate expiration across all your domains from a single dashboard. Get early warnings for certificates nearing expiry, even for wildcard and multi-domain certificates. Prevent the embarrassing and costly outage caused by an expired certificate.
Uptime Monitoring Best Practices
Monitor From Multiple Locations
A service that appears healthy from one location may be unreachable from another due to DNS issues, CDN misconfigurations, or regional network outages. Always select at least 3 monitoring locations across different geographic regions. Bleemeo's majority-vote algorithm then filters out single-location false positives while still detecting real regional outages.
Use Sub-60-Second Check Intervals
The faster you detect an outage, the faster you can respond. With Bleemeo's 60-second check intervals, you detect most outages within one minute of occurrence. For critical services, this sub-minute detection can mean the difference between a brief blip that users barely notice and a prolonged outage that generates support tickets and social media complaints.
Validate Content, Not Just Status Codes
An endpoint returning HTTP 200 does not guarantee it is working correctly. Configure response body validation to check for specific content that confirms real functionality — a product name on a product page, a JSON success field in an API response, or the absence of error strings. This catches issues like empty responses, cached error pages, and partial content delivery.
Set Up Alert Escalation
Not every alert needs to wake someone up at 3 AM. Configure escalation rules: start with a Slack notification for warnings, escalate to email for persistent issues, and trigger SMS or PagerDuty for critical outages exceeding a time threshold. This prevents alert fatigue while ensuring that real emergencies get immediate human attention.
Track Response Time Trends
An outage is the final symptom of a degrading service. Before going down, most services show gradually increasing response times. Monitor response time trends over weeks and months to catch performance regressions early. Set warning-level alerts on response time thresholds (e.g., P95 above 2 seconds) so you can investigate and fix issues before they escalate to full outages.

Everything you need to know about Bleemeo's uptime monitoring
What protocols does your uptime monitoring support?
Bleemeo's uptime monitoring supports HTTP/HTTPS for websites and APIs (with custom headers, status code validation, and response body checks), TCP for any port-based service (databases, custom applications), ICMP (Ping) for basic host reachability and latency, and DNS for domain resolution validation. For HTTPS monitors, we also automatically check SSL certificate validity and expiration dates.
How often do you run uptime checks?
Bleemeo performs uptime checks every 60 seconds from each selected monitoring location. This sub-minute frequency ensures you detect outages almost immediately, minimizing the time between an issue occurring and your team being notified. The check frequency is the same across all protocols (HTTP, HTTPS, TCP, ICMP, DNS).
Can I monitor internal services that aren't publicly accessible?
Yes, Bleemeo supports private probes. You can use any Glouton agent installed on your servers as a monitoring probe, allowing you to monitor URLs and services accessible only from your internal network. This is perfect for monitoring internal APIs, staging environments, intranet applications, or services behind firewalls. You can have unlimited private probes connected to your account.
Where are your monitoring locations?
Bleemeo operates monitoring probes from 7 global locations: Paris (France), Milan (Italy), Spain, Stockholm (Sweden), and Frankfurt (Germany) in Europe, plus Singapore in Asia and Ohio (USA) in North America. By default, European probes are enabled. You can select which locations to monitor from based on where your users are located.
How do I get notified when a service goes down?
An alert is raised when the majority of your selected probes fail to reach the service, preventing false positives from network routing issues. Notifications can be sent via email, SMS, or webhooks. You can also integrate with Slack, PagerDuty, OpsGenie, Microsoft Teams, and other notification platforms. Alert rules are customizable to match your incident response workflow.
What happens when my SSL certificate is about to expire?
For all HTTPS monitors, Bleemeo automatically tracks SSL certificate expiration. You'll receive a warning alert 20 days before expiration and a critical alert 10 days before expiration. We also monitor domain name expiration via WHOIS lookups (where available), with the same 20/10 day warning thresholds. This gives you ample time to renew certificates and domains before they impact your users.
Can I customize what constitutes a "successful" check?
Yes, Bleemeo offers advanced validation options. For HTTP/HTTPS monitors, you can specify: expected response codes (e.g., only 200, or any 2xx), text that must be present in the response body, text that must be absent (to detect error pages), and custom HTTP headers for authentication or API versioning. This ensures the check validates not just availability, but correct functionality.
Do you support response time monitoring?
Yes, Bleemeo tracks response time (latency) from each monitoring location on every check. You can view response time graphs in the monitor dashboard to identify performance degradation, compare latency across geographic locations, and set up alerts when response times exceed your thresholds. Historical latency data is retained for trend analysis and SLA reporting.
What is your uptime monitoring SLA?
Bleemeo provides detailed uptime statistics and SLA reports for your monitored services. The dashboard shows current status, response time trends, and historical availability percentages. You can track your services against internal SLA targets and generate reports for stakeholders. Our monitoring infrastructure itself is designed for high availability with redundant probes.
Can Bleemeo monitor APIs and web applications?
Yes, Bleemeo is well-suited for API monitoring. You can monitor REST APIs using GET, POST, and PUT methods, add custom HTTP headers for authentication (API keys, Bearer tokens), validate response codes and response body content, and track response times. Combined with multi-location monitoring, this gives you a comprehensive view of your API's global availability and performance.
