# Healthchecks
|
|
|
|
[Healthchecks](https://healthchecks.io/) is simple and Effective **Cron Job Monitoring** solution.
|
|
|
|
|
|
## Dependencies
|
|
|
|
This service requires the following other services:
|
|
|
|
- a [Postgres](postgres.md) database
|
|
- a [Traefik](traefik.md) reverse-proxy server
|
|
|
|
|
|
## Configuration
|
|
|
|
To enable this service, add the following configuration to your `vars.yml` file and re-run the [installation](../installing.md) process:
|
|
|
|
```yaml
|
|
########################################################################
|
|
# #
|
|
# healthchecks #
|
|
# #
|
|
########################################################################
|
|
|
|
healthchecks_enabled: true
|
|
|
|
healthchecks_hostname: mash.example.com
|
|
# Note: hosting under a path prefix is somewhat problematic. See below.
|
|
healthchecks_path_prefix: /healthchecks
|
|
|
|
########################################################################
|
|
# #
|
|
# /healthchecks #
|
|
# #
|
|
########################################################################
|
|
```
|
|
|
|
### URL
|
|
|
|
In the example configuration above, we configure the service to be hosted at `https://mash.example.com/healthchecks`.
|
|
|
|
You can remove the `healthchecks_path_prefix` variable definition, to make it default to `/`, so that the service is served at `https://mash.example.com/`.
|
|
|
|
**Note**: there are minor quirks when hosting under a subpath, such as:
|
|
|
|
- [Fonts not loading, because it attempts to load them from `/static` instead of `/path-prefix/static`](https://github.com/healthchecks/healthchecks/issues/822)
|
|
|
|
### Authentication
|
|
|
|
The first superuser account is created after installation. See [Usage](#usage).
|
|
You can create as many accounts as you wish.
|
|
|
|
### Email integration
|
|
|
|
To allow Healthchecks to send emails, add the following **additional** configuration:
|
|
|
|
```yaml
|
|
healthchecks_environment_variables_additional_variables: |
|
|
DEFAULT_FROM_EMAIL=healthchecks@example.com
|
|
EMAIL_HOST=smtp.example.com
|
|
EMAIL_HOST_PASSWORD=
|
|
EMAIL_HOST_USER=
|
|
EMAIL_PORT=587
|
|
EMAIL_USE_TLS=True
|
|
EMAIL_USE_VERIFICATION=True
|
|
```
|
|
|
|
### Integrating with other services
|
|
|
|
Refer to the [upstream `.env.example` file](https://github.com/healthchecks/healthchecks/blob/master/docker/.env.example) for discovering additional environment variables.
|
|
|
|
You can pass these to the Healthchecks container using the `healthchecks_environment_variables_additional_variables` variable. See [Email integration](#email-integration) for an example.
|
|
|
|
|
|
## Usage
|
|
|
|
After installation, you need to **create a superuser account**.
|
|
This is an interactive process which can be initiated by **SSH-ing into into the server** and **running a command** like this:
|
|
|
|
```sh
|
|
docker exec -it mash-healthchecks /opt/healthchecks/manage.py createsuperuser
|
|
```
|
|
|
|
After creating the superuser account, you can go to the [Healthchecks URL](#url) to log in and start setting up healthchecks.
