Gatus is a developer-oriented 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, Teams, PagerDuty, Discord, Twilio and many more.
I personally deploy it in my Kubernetes cluster and let it monitor the status of my
core applications: https://status.twin.sh/

## Why Gatus?
Before getting into the specifics, I want to address the most common question:
> Why would I use Gatus when I can just use Prometheus’ Alertmanager, Cloudwatch or even Splunk?
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.
Gatus, on the other hand, allows you to configure health checks for each of your features, which in turn allows it to
monitor these features and potentially alert you before any clients are impacted.
A sign you may want to look into Gatus is by simply asking yourself whether you'd receive an alert if your load balancer
was to go down right now. Will any of your existing alerts be triggered? Your metrics won’t report an increase in errors
if no traffic makes it to your applications. This puts you in a situation where your clients are the ones
that will notify you about the degradation of your services rather than you reassuring them that you're working on
fixing the issue before they even know about it.
## Features
The main features of Gatus are:
- **Highly flexible health check conditions**: While checking the response status may be enough for some use cases, Gatus goes much further and allows you to add conditions on the response time, the response body and even the IP address.
- **Ability to use Gatus for user acceptance tests**: Thanks to the point above, you can leverage this application to create automated user acceptance tests.
- **Very easy to configure**: Not only is the configuration designed to be as readable as possible, it's also extremely easy to add a new service or a new endpoint to monitor.
- **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, Google chat 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.
- **[Badges](#badges)**:  
- **Dark mode**

## Usage
Quick start
```console
docker run -p 8080:8080 --name gatus twinproduction/gatus
```
You can also use GitHub Container Registry if you prefer:
```console
docker run -p 8080:8080 --name gatus ghcr.io/twin/gatus
```
If you want to create your own configuration, see [Docker](#docker) for information on how to mount a configuration file.
Here's a simple example:
```yaml
endpoints:
- name: website # Name of your endpoint, can be anything
url: "https://twin.sh/health"
interval: 5m # Duration to wait between every status check (default: 60s)
conditions:
- "[STATUS] == 200" # Status must be 200
- "[BODY].status == UP" # The json path "$.status" must be equal to UP
- "[RESPONSE_TIME] < 300" # Response time must be under 300ms
- name: make-sure-header-is-rendered
url: "https://example.org/"
interval: 60s
conditions:
- "[STATUS] == 200" # Status must be 200
- "[BODY] == pat(*
Example Domain
*)" # Body must contain the specified header
```
This example would look similar to this:

By default, the configuration file is expected to be at `config/config.yaml`.
You can specify a custom path by setting the `GATUS_CONFIG_PATH` environment variable.
If `GATUS_CONFIG_PATH` points to a directory, all `*.yaml` and `*.yml` files inside said directory and its
subdirectories are merged like so:
- All maps/objects are deep merged (i.e. you could define `alerting.slack` in one file and `alerting.pagerduty` in another file)
- All slices/arrays are appended (i.e. you can define `endpoints` in multiple files and each endpoint will be added to the final list of endpoints)
- Parameters with a primitive value (e.g. `metrics`, `alerting.slack.webhook-url`, etc.) may only be defined once to forcefully avoid any ambiguity
- To clarify, this also means that you could not define `alerting.slack.webhook-url` in two files with different values. All files are merged into one before they are processed. This is by design.
> 💡 You can also use environment variables in the configuration file (e.g. `$DOMAIN`, `${DOMAIN}`)
>
> See [examples/docker-compose-postgres-storage/config/config.yaml](.examples/docker-compose-postgres-storage/config/config.yaml) for an example.
If you want to test it locally, see [Docker](#docker).

### Endpoints
Endpoints are URLs, applications, or services that you want to monitor. Each endpoint has a list of conditions that are
evaluated on an interval that you define. If any condition fails, the endpoint is considered as unhealthy.
You can then configure alerts to be triggered when an endpoint is unhealthy once a certain threshold is reached.

### External Endpoints
Unlike regular endpoints, external endpoints are not monitored by Gatus, but they are instead pushed programmatically.
This allows you to monitor anything you want, even when what you want to check lives in an environment that would not normally be accessible by Gatus.
For instance:
- You can create your own agent that lives in a private network and pushes the status of your services to a publicly-exposed Gatus instance
- You can monitor services that are not supported by Gatus
- You can implement your own monitoring system while using Gatus as the dashboard
| Parameter | Description | Default |
|:-------------------------------|:-----------------------------------------------------------------------------------------------------------------------|:--------------|
| `external-endpoints` | List of endpoints to monitor. | `[]` |
| `external-endpoints[].enabled` | Whether to monitor the endpoint. | `true` |
| `external-endpoints[].name` | Name of the endpoint. Can be anything. | Required `""` |
| `external-endpoints[].group` | Group name. Used to group multiple endpoints together on the dashboard.
See [Endpoint groups](#endpoint-groups). | `""` |
| `external-endpoints[].token` | Bearer token required to push status to. | Required `""` |
| `external-endpoints[].alerts` | List of all alerts for a given endpoint.
See [Alerting](#alerting). | `[]` |
Example:
```yaml
external-endpoints:
- name: ext-ep-test
group: core
token: "potato"
alerts:
- type: discord
description: "healthcheck failed"
send-on-resolved: true
```
To push the status of an external endpoint, the request would have to look like this:
```
POST /api/v1/endpoints/{key}/external?success={success}&error={error}
```
Where:
- `{key}` has the pattern `_` in which both variables have ` `, `/`, `_`, `,` and `.` replaced by `-`.
- Using the example configuration above, the key would be `core_ext-ep-test`.
- `{success}` is a boolean (`true` or `false`) value indicating whether the health check was successful or not.
- `{error}`: a string describing the reason for a failed health check. If {success} is false, this should contain the error message; if the check is successful, it can be omitted or left empty.
You must also pass the token as a `Bearer` token in the `Authorization` header.
### Conditions
Here are some examples of conditions you can use:
| Condition | Description | Passing values | Failing values |

#### Placeholders
| Placeholder | Description | Example of resolved value |
|:---------------------------|:------------------------------------------------------------------------------------------|:---------------------------------------------|
| `[STATUS]` | Resolves into the HTTP status of the request | `404` |
| `[RESPONSE_TIME]` | Resolves into the response time the request took, in ms | `10` |
| `[IP]` | Resolves into the IP of the target host | `192.168.0.232` |
| `[BODY]` | Resolves into the response body. Supports JSONPath. | `{"name":"john.doe"}` |
| `[CONNECTED]` | Resolves into whether a connection could be established | `true` |
| `[CERTIFICATE_EXPIRATION]` | Resolves into the duration before certificate expiration (valid units are "s", "m", "h".) | `24h`, `48h`, 0 (if not protocol with certs) |

#### Functions
| Function | Description | Example |
|:---------|:------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|:-----------------------------------|
| `len` | If the given path leads to an array, returns its length. Otherwise, the JSON at the given path is minified and converted to a string, and the resulting number of characters is returned. Works only with the `[BODY]` placeholder. | `len([BODY].username) > 8` |
| `has` | Returns `true` or `false` based on whether a given path is valid. Works only with the `[BODY]` placeholder. | `has([BODY].errors) == false` |
| `pat` | Specifies that the string passed as parameter should be evaluated as a pattern. Works only with `==` and `!=`. | `[IP] == pat(192.168.*)` |
| `any` | Specifies that any one of the values passed as parameters is a valid value. Works only with `==` and `!=`. | `[BODY].ip == any(127.0.0.1, ::1)` |
> 💡 Use `pat` only when you need to. `[STATUS] == pat(2*)` is a lot more expensive than `[STATUS] < 300`.
### Storage
| Parameter | Description | Default |
|:------------------|:---------------------------------------------------------------------------------------------------------------------------------------------------|:-----------|
| `storage` | Storage configuration | `{}` |
| `storage.path` | Path to persist the data in. Only supported for types `sqlite` and `postgres`. | `""` |
| `storage.type` | Type of storage. Valid types: `memory`, `sqlite`, `postgres`. | `"memory"` |
| `storage.caching` | Whether to use write-through caching. Improves loading time for large dashboards.
Only supported if `storage.type` is `sqlite` or `postgres` | `false` |
The results for each endpoint health check as well as the data for uptime and the past events must be persisted
so that they can be displayed on the dashboard. These parameters allow you to configure the storage in question.
- If `storage.type` is `memory` (default):
```yaml
# Note that this is the default value, and you can omit the storage configuration altogether to achieve the same result.
# Because the data is stored in memory, the data will not survive a restart.
storage:
type: memory
```
- If `storage.type` is `sqlite`, `storage.path` must not be blank:
```yaml
storage:
type: sqlite
path: data.db
```
See [examples/docker-compose-sqlite-storage](.examples/docker-compose-sqlite-storage) for an example.
- If `storage.type` is `postgres`, `storage.path` must be the connection URL:
```yaml
storage:
type: postgres
path: "postgres://user:password@127.0.0.1:5432/gatus?sslmode=disable"
```
See [examples/docker-compose-postgres-storage](.examples/docker-compose-postgres-storage) for an example.
### Client configuration

the client used to send the request.
| Parameter | Description | Default |
|:---------------------------------------|:----------------------------------------------------------------------------|:----------------|
| `client.insecure` | Whether to skip verifying the server's certificate chain and host name. | `false` |

| `client.tls.renegotiation` | Type of renegotiation support to provide. (`never`, `freely`, `once`). | `"never"` |
| `client.network` | The network to use for ICMP endpoint client (`ip`, `ip4` or `ip6`). | `"ip"` |
> 📝 Some of these parameters are ignored based on the type of endpoint. For instance, there's no certificate involved
> in ICMP requests (ping), therefore, setting `client.insecure` to `true` for an endpoint of that type will not do anything.
This default configuration is as follows:
```yaml
client:
insecure: false
ignore-redirect: false
timeout: 10s
```
Note that this configuration is only available under `endpoints[]`, `alerting.mattermost` and `alerting.custom`.
Here's an example with the client configuration under `endpoints[]`:
```yaml
endpoints:
- name: website
url: "https://twin.sh/health"
client:
insecure: false
ignore-redirect: false
timeout: 10s
conditions:
- "[STATUS] == 200"
```
This example shows how you can specify a custom DNS resolver:
```yaml
endpoints:
- name: with-custom-dns-resolver
url: "https://your.health.api/health"
client:
dns-resolver: "tcp://8.8.8.8:53"
conditions:
- "[STATUS] == 200"
```
This example shows how you can use the `client.oauth2` configuration to query a backend API with `Bearer token`:
```yaml
endpoints:
- name: with-custom-oauth2
url: "https://your.health.api/health"
client:
oauth2:
token-url: https://your-token-server/token
client-id: 00000000-0000-0000-0000-000000000000
client-secret: your-client-secret
scopes: ['https://your.health.api/.default']
conditions:
- "[STATUS] == 200"
```
This example shows how you can use the `client.identity-aware-proxy` configuration to query a backend API with `Bearer token` using Google Identity-Aware-Proxy:
```yaml
endpoints:
- name: with-custom-iap
url: "https://my.iap.protected.app/health"
client:
identity-aware-proxy:
audience: "XXXXXXXX-XXXXXXXXXXXX.apps.googleusercontent.com"
conditions:
- "[STATUS] == 200"
```
> 📝 Note that Gatus will use the [gcloud default credentials](https://cloud.google.com/docs/authentication/application-default-credentials) within its environment to generate the token.
This example shows you how you can use the `client.tls` configuration to perform an mTLS query to a backend API:
```yaml
endpoints:
- name: website
url: "https://your.mtls.protected.app/health"
client:
tls:
certificate-file: /path/to/user_cert.pem
private-key-file: /path/to/user_key.pem
renegotiation: once
conditions:
- "[STATUS] == 200"
```
> 📝 Note that if running in a container, you must volume mount the certificate and key into the container.
### Alerting
Gatus supports multiple alerting providers, such as Slack and PagerDuty, and supports different alerts for each
individual endpoints with configurable descriptions and thresholds.
Alerts are configured at the endpoint level like so:
| Parameter | Description | Default |
|:-----------------------------|:-------------------------------------------------------------------------------|:--------------|
| `alerts` | List of all alerts for a given endpoint. | `[]` |
| `alerts[].type` | Type of alert.
See table below for all valid types. | Required `""` |
| `alerts[].enabled` | Whether to enable the alert. | `true` |
| `alerts[].failure-threshold` | Number of failures in a row needed before triggering the alert. | `3` |
| `alerts[].success-threshold` | Number of successes in a row before an ongoing incident is marked as resolved. | `2` |
| `alerts[].send-on-resolved` | Whether to send a notification once a triggered alert is marked as resolved. | `false` |
| `alerts[].description` | Description of the alert. Will be included in the alert sent. | `""` |
| `alerts[].provider-override` | Alerting provider configuration override for the given alert type | `{}` |
Here's an example of what an alert configuration might look like at the endpoint level:
```yaml
endpoints:
- name: example
url: "https://example.org"
conditions:
- "[STATUS] == 200"
alerts:
- type: slack
description: "healthcheck failed"
send-on-resolved: true
```
You can also override global provider configuration by using `alerts[].provider-override`, like so:
```yaml
endpoints:
- name: example
url: "https://example.org"
conditions:
- "[STATUS] == 200"
alerts:
- type: slack
provider-override:
webhook-url: "https://hooks.slack.com/services/**********/**********/**********"
```
> 📝 If an alerting provider is not properly configured, all alerts configured with the provider's type will be
> ignored.

[ntfy](https://github.com/binwiederhier/ntfy) is an amazing project that allows you to subscribe to desktop
and mobile notifications, making it an awesome addition to Gatus.
Example:
```yaml
alerting:
ntfy:
topic: "gatus-test-topic"
priority: 2
token: faketoken

```
#### Configuring PagerDuty alerts
| Parameter | Description | Default |
|:---------------------------------------|:-------------------------------------------------------------------------------------------|:--------|
| `alerting.pagerduty` | Configuration for alerts of type `pagerduty` | `{}` |
| `alerting.pagerduty.integration-key` | PagerDuty Events API v2 integration key | `""` |

| `alerting.pagerduty.overrides[].group` | Endpoint group for which the configuration will be overridden by this configuration | `""` |
| `alerting.pagerduty.overrides[].*` | See `alerting.pagerduty.*` parameters | `{}` |
It is highly recommended to set `endpoints[].alerts[].send-on-resolved` to `true` for alerts
of type `pagerduty`, because unlike other alerts, the operation resulting from setting said
parameter to `true` will not create another incident but mark the incident as resolved on
PagerDuty instead.
Behavior:
- By default, `alerting.pagerduty.integration-key` is used as the integration key
- If the endpoint being evaluated belongs to a group (`endpoints[].group`) matching the value of `alerting.pagerduty.overrides[].group`, the provider will use that override's integration key instead of `alerting.pagerduty.integration-key`'s
```yaml
alerting:
pagerduty:
integration-key: "********************************"
# You can also add group-specific integration keys, which will
# override the integration key above for the specified groups
overrides:
- group: "core"
integration-key: "********************************"
endpoints:
- name: website
url: "https://twin.sh/health"
interval: 30s
conditions:
- "[STATUS] == 200"

failure-threshold: 3
success-threshold: 5
send-on-resolved: true
description: "healthcheck failed"
