# Perfdata collector
|
|
|
|
The perfdata collector exposes any configured metric.
|
|
|
|
| | |
|
|
|---------------------|-------------------------|
|
|
| Metric name prefix | `perfdata` |
|
|
| Data source | Performance Data Helper |
|
|
| Enabled by default? | No |
|
|
|
|
## Flags
|
|
|
|
|
|
### `--collector.perfdata.objects`
|
|
|
|
Objects is a list of objects to collect metrics from. The value takes the form of a JSON array of strings. YAML is also supported.
|
|
|
|
The collector supports only english named counter. Localized counter-names are not supported.
|
|
|
|
#### Schema
|
|
|
|
YAML:
|
|
```yaml
|
|
- object: "Processor Information"
|
|
instances: ["*"]
|
|
instance_label: "core"
|
|
counters:
|
|
"% Processor Time": {}
|
|
- object: "Memory"
|
|
counters:
|
|
"Cache Faults/sec":
|
|
type: "counter"
|
|
```
|
|
|
|
JSON:
|
|
|
|
```json
|
|
[
|
|
{"object":"Processor Information","instance_label": "core","instances":["*"],"counters": {"% Processor Time": {}}},
|
|
{"object":"Memory","counters": {"Cache Faults/sec": {"type": "counter"}}}
|
|
]
|
|
```
|
|
|
|
#### name
|
|
|
|
ObjectName is the Object to query for, like Processor, DirectoryServices, LogicalDisk or similar.
|
|
|
|
The collector supports only english named counter. Localized counter-names are not supported.
|
|
|
|
#### instances
|
|
|
|
The instances key (this is an array) declares the instances of a counter you would like returned, it can be one or more values.
|
|
|
|
Example: Instances = `["C:","D:","E:"]`
|
|
|
|
This will return only for the instances C:, D: and E: where relevant. To get all instances of a Counter, use `["*"]` only.
|
|
|
|
Some Objects like `Memory` do not have instances to select from at all. In this case, the `instances` key can be omitted.
|
|
|
|
#### counters
|
|
|
|
The Counters key (this is an object) declares the counters of the ObjectName you would like returned, it can also be one or more values.
|
|
|
|
Example: Counters = `{"% Idle Time": {}, "% Disk Read Time": {}, "% Disk Write Time": {}}`
|
|
|
|
This must be specified for every counter you want the results. Wildcards are not supported.
|
|
|
|
#### counters Sub-Schema
|
|
|
|
##### type
|
|
|
|
This key is optional. It indicates the type of the counter. The value can be `counter` or `gauge`.
|
|
If not specified, the windows_exporter will try to determine the type based on the counter type.
|
|
|
|

## Metrics
|
|
|
|
The perfdata collector returns metrics based on the user configuration.
|
|
The metrics are named based on the object name and the counter name.
|
|
The instance name is added as a label to the metric.
