The textfile collector exposes metrics from files written by other processes.
Metric name prefix | textfile |
Classes | None |
Enabled by default? | Yes |
The directory containing the files to be ingested. Only files with the extension .prom
are read. The .prom
file must end with an empty line feed to work properly.
Default value: C:\Program Files\wmi_exporter\textfile_inputs
Required: No
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 |

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.
