About Overmonitor is a cloud-based infrastructure, website, and endpoint monitoring platform built for fast setup without enterprise complexity. Monitor websites, APIs, servers, processes, Windows services, event logs, performance counters, SNMP data, uptime, response time, DNS, SSL certificates, internal endpoints, and network health from one dashboard. The lightweight 2.1 MB agent runs as an idle process, requires no inbound firewall exceptions or open ports, and sends a secure heartbeat every minute. Configure monitoring quickly through the web interface and target checks by city-level geography. Maintenance windows suppress expected noise, while configurable alerts, push notifications, and audible dashboards keep the right people informed. Multi-location endpoint checks validate incidents, reduce false alarms, expose regional problems, and reveal how availability and responsiveness differ across target markets. Distributed Monitors expand Overmonitor’s network by allowing eligible servers to opt in and check up to 10 external endpoints. Checks add negligible data to the existing heartbeat, require no extra configuration or firewall changes, execute no remote web scripts, and store no monitored data on the server. If a participating server or network becomes unavailable, its checks are automatically reassigned. Participation also earns prorated invoice credits. Trend Analysis turns historical infrastructure metrics into proactive capacity planning. Choose from thousands of performance counters, including CPU utilization, available memory, and disk space, then assign minimum and maximum thresholds. Once enough data has been collected, Overmonitor applies linear regression to estimate when a metric may cross its limits. A configurable planning horizon controls when responsible team members are alerted, helping you rebalance workloads, tune resources, or scale capacity before performance becomes an outage or unbudgeted emergency. Trend Analysis is included with every server metric at no additional charge. Overmonitor also includes process rollups, embeddable performance graphs, endpoint health visibility, flexible retention, multiple users with roles, and à la carte pricing so you pay only for the monitoring you need. Detect outages, correlate website symptoms with server health, analyze performance, track availability, and improve end-user experience before small issues become downtime.

Pricing $3.00 per month Pricing starts at $3.00/month for one basic endpoint monitor from one monitoring location with one user. Overmonitor uses flexible à la carte pricing, so costs scale based on endpoint type, number of endpoints, monitoring locations, user access, user agents, data retention, and optional features. HTTP checks, additional monitoring locations, longer retention, and expanded access can be added as needed. Discounts may be available for distributed monitoring enrollment.

		Pros & Cons from Real Users Pros The interface is very intuitive and easy to configure. PRTG supports a wide variety of sensors out of the box and can monitor almost any device or service through SNMP, WMI, API, or custom scripts. The automatic network discovery saves a lot of setup time, and the alerting system is flexible and reliable. Easy Installation & Setup: Quick to install, straightforward to add devices; PRTG auto-discovers sensors with minimal input required. User-Friendly Interface: Clean interface with intuitive navigation—great for beginners and power users alike. Automatic Device & Sensor Discovery: PRTG finds and sets up relevant sensors for new devices automatically, minimizing manual configuration. Customizable Dashboards & Alerts: Effective visualization tools and flexible alerting keep you informed about network health. Free Version Available: The free version (up to 100 sensors) is more than sufficient for most home and small lab setups. Versatile Monitoring: Supports a wide range of devices and protocols (SNMP, WMI, flow, etc.), covering most network needs. Active Community & Documentation: Lots of online help and documentation for troubleshooting and tips. PRTG is an amazingly simple tool that helps monitor all the equipment we have in our organization. With this system, in any malfunction or crisis, we can quickly diagnose the source of the problem and solve it in an instant. We have configured all the servers and equipment in the system and it knows how to give us a quick look as soon as something happens. And that way, we can diagnose the problem quickly. We've had a very positive and satisfying experience with PRTG over the years. We've been using the product for several years now, and it's proven to be the perfect solution for monitoring our network infrastructure and applications. PRTG is intuitive and well-designed, making it easy to create detailed dashboards and maps that give us a clear visual representation of the status of critical machines and services. The notification system is also very well thought out, allowing us to react quickly to any anomalies. One of PRTG’s key strengths is that it's constantly evolving, which means we regularly gain access to new sensors that we can deploy to achieve more precise and comprehensive monitoring of our systems. The user community plays an essential role as well, often helping us solve very specific sensor-related issues. On top of that, the technical support team is responsive and effective, often providing spot-on answers that help resolve complex problems. At this point, we honestly can’t imagine working without PRTG — it’s become a central part of our IT operations. The number of sensor types is outstanding. Not just SNMP but a multitude of standard sensor imputs are possible as well as custom scripts in various formats. The remote probe is great for multitenant or remote sites. Cons The web interface can become slow when handling very large environments with thousands of sensors. Some advanced reporting features require manual setup, and the mobile app, while functional, could be improved for better usability. Sensor Counting Can Be Confusing: Some users find the way PRTG counts “sensors” (one sensor per metric) a bit confusing, which can eat up your free limit quickly. Resource Use: The software can be resource-intensive on larger setups; may require better hardware to run smoothly if scaling up. Overwhelming Amount of Data: For home users, the sheer volume of information and settings might be daunting at first. Interface Feels Dated to Some: While functional, a few users feel the web UI could use a more modern look. Limited by Free Tier: Advanced features and larger environments may require a paid license. The price is very expensive and not suitable for every organization, which is a shame. If the price were more affordable, maybe more organizations would purchase it. What I like less about the software is the way lookups are managed. It could be more user-friendly — right now, you have to manually edit text files directly on the probe, which isn't very convenient. There should be a dedicated interface for this, similar to how thresholds are managed. Also, the maps feature feels a bit limited, and there's a lack of confirmation prompts when deleting items. One wrong move and you can lose everything you've built. There should be more validation steps when modifying maps, especially for deletions. Just hovering over an item and accidentally clicking the trash icon can wipe out your work in an instant… Hardware Scaling of large PRTG installations is something to plan ahead for
