# vmware_exporter
VMWare VCenter Exporter for Prometheus.

Get VMWare VCenter information:
- Current number of active snapshots
- Snapshot Unix timestamp creation date
- Datastore size and other stuff
- Basic VM and Host metrics

## Usage

- install with `$ python setup.py install` or `$ pip install vmware_exporter`
- Create a `config.yml` file based on the `config.yml.sample` with at least a `default` section.
- Run `$ vmware_exporter -c /path/to/your/config`
- Go to http://localhost:9272/metrics?target=vcenter.company.com to see metrics

Alternatively, if you don't wish to install the package, run using `$ vmware_exporter/vmware_exporter.py`

### Prometheus configuration

You can use the following parameters in prometheus configuration file. The `params` section is used to manage multiple login/passwords.

```
- job_name: 'vmware_vcenter'
metrics_path: '/metrics'
static_configs:
- targets:
- 'vcenter.company.com
relabel_configs:
- source_labels: [__address__]
target_label: __param_target
- source_labels: [__param_target]
target_label: instance
- target_label: __address__
replacement: localhost:9272

- job_name: 'vmware_esx'
metrics_path: '/metrics'
file_sd_configs:
- files:
- /etc/prometheus/esx.yml
params:
section: [esx]
relabel_configs:
- source_labels: [__address__]
target_label: __param_target
- source_labels: [__param_target]
target_label: instance
- target_label: __address__
replacement: localhost:9272
```

## Current Status

- VCenter and ESXi 6 and 6.5 have been tested.
- VM information, Snapshot, Host and Datastore basic information is exported, i.e:
