# CAAS KUBERNETES VELERO DataDog monitors
## How to use this module
```
module "datadog-monitors-caas-kubernetes-velero" {
source = "claranet/monitors/datadog//caas/kubernetes/velero"
version = "{revision}"
environment = var.environment
message = module.datadog-message-alerting.alerting-message
}
```
## Purpose
Creates DataDog monitors with the following checks:
- Velero backup deletion failure
- Velero backup failure
- Velero backup partial failure
- Velero scheduled backup missing
- Velero volume snapshot failure

### How to configure Datadog agent for these monitors ?
You can configure Datadog agent by autodiscovery pod annotations or by configuration file.
#### Configuration by autodiscovery pod annotations
Add these annotations to Velero pods:
```
podAnnotations: {
"ad.datadoghq.com/velero.check_names": '["openmetrics"]',
"ad.datadoghq.com/velero.init_configs": '[{}]',
"ad.datadoghq.com/velero.instances": '[{"prometheus_url": "http://%%host%%:8085/metrics", "namespace": "velero", "metrics": ["velero*"]}]'
}
```
#### Configuration by configuration file
Example of `openmetrics.d/conf.yaml`:
```
init_config:
instances:
## @param prometheus_url - string - required
## The URL where your application metrics are exposed by Prometheus.
#
- prometheus_url: http://velero.velero.svc.cluster.local:8085/metrics
## @param namespace - string - required
## The namespace to be prepended to all metrics.
#
namespace: "velero"
## @param metrics - list of strings - required
## List of metrics to be fetched from the prometheus endpoint, if there's a
## value it'll be renamed. This list should contain at least one metric
#
metrics:
- velero*
```
### How to monitor multiple schedule witch have different frequencies ?
If you have multiple Velero schedules with different frequencies, you must duplicate this module and disable common monitors in the others instance of module.
