-Once you've installed FusionAuth and your applications use it for authentication, you'll want to ensure FusionAuth remains online and operational. An ecosystem of tools, protocols, and paid services are available to monitor applications and provide telemetry (remote measurement) to help you maintain FusionAuth's availability and performance.

 This overview article will introduce you to various metrics (measurements) you can extract from FusionAuth and common monitoring tools to process, store, and visualize them.

 ### What Is Prometheus?
 
-[Prometheus](https://prometheus.io/docs/introduction/overview) is a monitoring and alerting toolkit with a built-in time series database designed to efficiently store metrics and provide data through a custom query language. Prometheus offers instrumentation tools to collect metrics from networks, machines, and some [programming languages](https://prometheus.io/docs/instrumenting/clientlibs/). While Prometheus includes basic charting capabilities, more advanced dashboards require integration with Grafana. You can use the Prometheus [Alertmanager](https://github.com/prometheus/alertmanager) to handle alerts.

 Prometheus can be used for all activities in the monitoring chain, though some at a very basic level, but should [not be used to store logs](https://prometheus.io/docs/introduction/faq/#how-to-feed-logs-into-prometheus).

 - Email: You will probably need to subscribe to a mail sender service to receive email alerts, unless your internet provider allows you access to the SMTP protocol.
 - Computer chat apps: Computer chat apps like Slack and Discord can receive alert messages in a specific channel for free. Slack and Discord clients can be installed on your phone to be sure you never miss an alert.
+- Public notification web apps: There are public websites, like https://ntfy.sh and https://webhook.site that allow anyone to send messages to named channels for free. ntfy also has a mobile app that will notify you when a channel receives a message. Since these services are public, you should never send secrets to them.
 - Phone chat apps: For example, WhatsApp and Threema. WhatsApp requires a phone number to sign up. Threema does not need a phone number but requires you to buy the mobile app for a small one-time fee. Both services charge a fee for businesses to send messages to users.
 
 Grafana's OnCall tool consolidates and redirects multiple alerts from various systems. This might be a good option for you if you have support staff that monitor an alert system in shifts rather than wait to receive an email.

 There are other paid and hosted monitoring services that aren't discussed in this article, like Splunk (integration guide with FusionAuth [here](/docs/operate/secure-and-monitor/splunk)) and Datadog, which have their own tools and typically implement the OpenTelemetry Protocol.
