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.

- **Alerting**: While having a pretty visual dashboard is useful to keep track of the state of your application(s), you probably don't want to stare at it all day. Thus, notifications via Slack, Mattermost, Messagebird, PagerDuty, Twilio and Teams are supported out of the box with the ability to configure a custom alerting provider for any needs you might have, whether it be a different provider or a custom application that manages automated rollbacks.
- **Metrics**
- **Low resource consumption**: As with most Go applications, the resource footprint that this application requires is negligibly small.

To ensure that Gatus provides reliable and accurate results (i.e. response time), Gatus only evaluates one service at a time
In other words, even if you have multiple services with the exact same interval, they will not execute at the same time.

In other words, even if you have multiple endpoints with the exact same interval, they will not execute at the same time.
You can test this yourself by running Gatus with several services configured with a very short, unrealistic interval,
such as 1ms. You'll notice that the response time does not fluctuate - that is because while services are evaluated on
different goroutines, there's a global lock that prevents multiple services from running at the same time.

Unfortunately, there is a drawback. If you have a lot of services, including some that are very slow or prone to time out (the default

The interval does not include the duration of the request itself, which means that if an endpoint has an interval of 30s

While this does not prevent Gatus' from performing health checks on all other endpoints, it may cause Gatus to be unable
to respect the configured interval, for instance:
- Service A has an interval of 5s, and times out after 10s to complete
- Service B has an interval of 5s, and takes 1ms to complete
- Service B will be unable to run every 5s, because service A's health evaluation takes longer than its interval
- Endpoint A has an interval of 5s, and times out after 10s to complete
- Endpoint B has an interval of 5s, and takes 1ms to complete
- Endpoint B will be unable to run every 5s, because endpoint A's health evaluation takes longer than its interval
To sum it up, while Gatus can really handle any interval you throw at it, you're better off having slow requests with
higher interval.

There are three main reasons why you might want to disable the monitoring lock:
- You're using Gatus for load testing (each services are periodically evaluated on a different goroutine, so
technically, if you create 100 services with a 1 seconds interval, Gatus will send 100 requests per second)
- You have a _lot_ of services to monitor
- You want to test multiple services at very short interval (< 5s)

The path to generate a badge is the following:
```
/api/v1/services/{key}/uptimes/{duration}/badge.svg

```
Where:
- `{duration}` is `7d`, `24h` or `1h`
- `{key}` has the pattern `<GROUP_NAME>_<SERVICE_NAME>` in which both variables have ` `, `/`, `_`, `,` and `.` replaced by `-`.
- `{key}` has the pattern `<GROUP_NAME>_<ENDPOINT_NAME>` in which both variables have ` `, `/`, `_`, `,` and `.` replaced by `-`.
For instance, if you want the uptime during the last 24 hours from the service `frontend` in the group `core`,

# PagerDuty + Gatus Integration Benefits
- Notify on-call responders based on alerts sent from Gatus.
- Incidents will automatically resolve in PagerDuty when the service that caused the incident in Gatus returns to a healthy state.
- Incidents will automatically resolve in PagerDuty when the endpoint that caused the incident in Gatus returns to a healthy state.
# How it Works
- Services that do not meet the user-specified conditions and that are configured with alerts of type `pagerduty` will trigger a new incident on the corresponding PagerDuty service when the alert's defined `failure-threshold` has been reached.
- Once the unhealthy services have returned to a healthy state for the number of executions defined in `success-threshold`, the previously triggered incident will be automatically resolved.
- Endpoints that do not meet the user-specified conditions and that are configured with alerts of type `pagerduty` will trigger a new incident on the corresponding PagerDuty service when the alert's defined `failure-threshold` has been reached.
- Once the unhealthy endpoints have returned to a healthy state for the number of executions defined in `success-threshold`, the previously triggered incident will be automatically resolved.
