Overmonitor
Unistellar Industries, LLC
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. -

BoxWatch
BoxWatch
BoxWatch is server monitoring that does the job of four tools at once: metrics, cron heartbeats, uptime checks, and process monitoring. One agent, one dashboard, one bill.

Metrics: CPU, memory, disk, network, load, and uptime, collected by a small open-source bash agent installed with one curl command. Trend charts, side-by-side comparison views, and disk-full prediction that warns you days before a volume actually fills. Cron heartbeats: ping a URL when a job finishes, get alerted when the ping is late or missing. Four alert types with transition-based dedup so you never get spammed. Uptime checks: HTTP, TCP, and TLS-expiry probes executed by your own deployed BoxWatch agents.Starting Price: $0 -

Prometheus
Prometheus
Power your metrics and alerting with a leading open-source monitoring solution. Prometheus fundamentally stores all data as time series: streams of timestamped values belonging to the same metric and the same set of labeled dimensions. Besides stored time series, Prometheus may generate temporary derived time series as the result of queries. Prometheus provides a functional query language called PromQL (Prometheus Query Language) that lets the user select and aggregate time series data in real time. The result of an expression can either be shown as a graph, viewed as tabular data in Prometheus's expression browser, or consumed by external systems via the HTTP API. Prometheus is configured via command-line flags and a configuration file. While the command-line flags configure immutable system parameters (such as storage locations, amount of data to keep on disk and in memory, etc.).Starting Price: Free -

Instrumental
Expected Behavior
Over and over again, we were consulting on software projects that couldn’t confidently answer “Is the application working correctly right now?” It’s not that they didn’t have monitoring tools. It’s not that they didn’t have smart people on their team. They always did. When it came down to it, the available tools just weren’t answering the right questions about the technical health of the software. “Turn-key” monitoring sounds great and it’s easy to set up, but if it doesn’t actually answer questions then it’s just wasting money. Instrumental is application and server monitoring that fits like a glove. Everything that’s unique, interesting, and important about your software is now effortless to monitor. It has a powerful query language for answering questions, incredible visualizations, first-class sharing features, and it’s affordable to both small companies and the world’s largest enterprises.Starting Price: $5.00/month -
