# textfile collector
|
|
|
|
The textfile collector exposes metrics from files written by other processes.
|
|
|
|
|||
|
|
-|-
|
|
Metric name prefix | `textfile`
|
|
Classes | None
|
|
Enabled by default? | Yes
|
|
|
|
## Flags
|
|
|
|
### `--collector.textfile.directory`
|
|
:warning: DEPRECATED Use `--collector.textfile.directories`
|
|
|
|
<br>
|
|
|
|
### `--collector.textfile.directories`
|
|
One or multiple directories containing the files to be ingested.
|
|
|
|
E.G. `--collector.textfile.directories="C:\MyDir1,C:\MyDir2"`
|
|
|
|
Default value: `C:\Program Files\windows_exporter\textfile_inputs`
|
|
|
|
Required: No
|
|
|
|
> **Note:**
|
|
> - If there are duplicated filenames among the directories, only the first one found will be read. For any other files with the same name, the `windows_textfile_scrape_error` metric will be set to 1 and a error message will be logged.
|
|
> - Only files with the extension `.prom` are read. The `.prom` file must end with an empty line feed to work properly.
|
|
|
|
|
|
|
|
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
|
|
-----|-------------|------|-------
|
|
`windows_textfile_scrape_error` | 1 if there was an error opening or reading a file, 0 otherwise | gauge | None
|
|
`windows_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.directories` (default `C:\Program Files\windows_exporter\textfile_inputs`), generates a valid `.prom` file that should successfully ingested by windows_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"
|
|
}
|
|
```
