# gatus # gatus
## Overview ## Overview
The gatus Stack is a service monitor for NetGrimoire, providing real-time monitoring and visibility into the system's health. It consists of two main services: Gatus and its reverse proxy service, which exposes the Gatus application through a custom domain. The gatus stack is a NetGrimoire service monitor that provides real-time monitoring and alerts for the Gatus application. It uses Docker Swarm as its underlying infrastructure and exposes services via Caddy reverse proxies.

## Build & Configuration ## Build & Configuration
### Prerequisites ### Prerequisites
No specific prerequisites are required for this stack. To build and deploy the gatus stack, you need to have Docker Swarm installed on your manager node (znas). Additionally, ensure that you have a Caddy instance running with the required labels.

### Primary Use Cases ### Primary Use Cases
Gatus provides real-time monitoring and visibility into the system's health, allowing administrators to quickly identify issues and take corrective action. To use the gatus monitor in NetGrimoire, you need to integrate it with other services that expose their metrics via Caddy reverse proxies.
### NetGrimoire Integrations ### NetGrimoire Integrations
Gatus integrates with other services in NetGrimoire through environment variables and labels, such as authentik and crowdsec. The gatus stack integrates with other NetGrimoire services such as Crowdsec and Authentik. The `GATUS_CONFIG_PATH` environment variable is used to load the configuration from a YAML file.

## Operations ## Operations
### Monitoring ### Monitoring
Monitoring is enabled for the gatus service using Kuma monitors.
```bash ```bash
docker stack services gatus docker stack services gatus
```
To view logs, use:
```bash
docker service logs -f gatus docker service logs -f gatus
``` ```
### Backups ### Backups
Critical: /DockerVol/gatus/data Critical data is stored in the `/DockerVol/gatus/data` directory. It's essential to ensure that this volume is properly backed up regularly.
Reconstructable: /DockerVol/gatus/config
### Restore ### Restore
To restore the gatus stack from a backup, run the following command:
```bash ```bash
