## Flags
|
|

|
|
|
|
The directory containing the files to be ingested. Only files with the extension `.prom` are read.

|
|
Required: No

## Metrics
|
|
|
|
Metrics will primarily come from the files on disk. The below listed metrics
|
|
are collected to give information about the reading of the metrics themselves.
|
|
|
|
Name | Description | Type | Labels
|
|
-----|-------------|------|-------
|
|
`wmi_textfile_scrape_error` | 1 if there was an error opening or reading a file, 0 otherwise | gauge | None
|
|
`wmi_textfile_mtime_seconds` | Unix epoch-formatted mtime (modified time) of textfiles successfully read | gauge | file
|
|
|
|

# Example use
|
|
This Powershell script, when run in the `collector.textfile.directory` (default `C:\Program Files\wmi_exporter\textfile_inputs`), generates a valid `.prom` file that should successfully ingested by wmi_exporter.
|
|
|
|
```Powershell
|
|
$alpha = 42
|
|
$beta = @{ left=3.1415; right=2.718281828; }
|
|
|
|
Set-Content -Path test1.prom -Encoding Ascii -NoNewline -Value ""
|
|
Add-Content -Path test1.prom -Encoding Ascii -NoNewline -Value "# HELP test_alpha_total Some random metric.`n"
|
|
Add-Content -Path test1.prom -Encoding Ascii -NoNewline -Value "# TYPE test_alpha_total counter`n"
|
|
Add-Content -Path test1.prom -Encoding Ascii -NoNewline -Value "test_alpha_total ${alpha}`n"
|
|
Add-Content -Path test1.prom -Encoding Ascii -NoNewline -Value "# HELP test_beta_bytes Some other metric.`n"
|
|
Add-Content -Path test1.prom -Encoding Ascii -NoNewline -Value "# TYPE test_beta_bytes gauge`n"
|
|
foreach ($k in $beta.Keys) {
|
|
Add-Content -Path test1.prom -Encoding Ascii -NoNewline -Value "test_beta_bytes{spin=""${k}""} $( $beta[$k] )`n"
|
|
}
|
|
```
