gatus - ⛑ Gatus - Automated service health dashboard

•    Go

---

Gatus is a health dashboard that gives you the ability to monitor your services using HTTP, ICMP, TCP, and even DNS queries as well as evaluate the result of said queries by using a list of conditions on values like the status code, the response time, the certificate expiration, the body and many others. The icing on top is that each of these health checks can be paired with alerting via Slack, PagerDuty, Discord and even Twilio. Neither of these can tell you that there’s a problem if there are no clients actively calling the endpoint. In other words, it's because monitoring metrics mostly rely on existing traffic, which effectively means that unless your clients are already experiencing a problem, you won't be notified.

automatron - Infrastructure monitoring framework turning DevOps runbooks into automated actions

•    Python

---

Automatron is a framework for creating self-healing infrastructure. Simply put, it detects system events & takes action to correct them. The goal of Automatron is to allow users to automate the execution of common tasks performed during system events. These tasks can be as simple as sending an email to as complicated as restarting services across multiple hosts.

goss - Quick and Easy server testing/validation

•    Go

---

Note: For some Docker/Kubernetes healthcheck, health endpoint, and container ordering examples, see my blog post here. Goss is a YAML based serverspec alternative tool for validating a server’s configuration. It eases the process of writing tests by allowing the user to generate tests from the current system state. Once the test suite is written they can be executed, waited-on, or served as a health endpoint.

AppMetrics - App Metrics is an open-source and cross-platform

•    CSharp

---

App Metrics is an open-source and cross-platform .NET library used to record metrics within an application. App Metrics can run on .NET Core or on the full .NET framework also supporting .NET 4.5.2. App Metrics abstracts away the underlaying repository of your Metrics for example InfluxDB, Graphite, Elasticsearch etc, by sampling and aggregating in memory and providing extensibility points to flush metrics to a repository at a specified interval.App Metrics provides various metric types to measure things such as the rate of requests, counting the number of user logins over time, measure the time taken to execute a database query, measure the amount of free memory and so on. Metrics types supported are Gauges, Counters, Meters, Histograms and Timers and Application Performance Indexes Apdex.
