| # filetime collector | ||
|
|
||
| The filetime collector exposes modified timestamps of files in the filesystem. | ||
|
|
||
| The collector | ||
|
|
||
| ||| | ||
| -|- | ||
| Metric name prefix | `filetime` | ||
| Enabled by default? | No | ||
|
|
||
| ## Flags | ||
|
|
||
| ### `--collectors.filetime.file-patterns` | ||
| Comma-separated list of file patterns. Each pattern is a glob pattern that can contain `*`, `?`, and `**` (recursive). | ||
| See https://github.com/bmatcuk/doublestar#patterns for an extended description of the pattern syntax. | ||
|
|
||
| ## Metrics | ||
|
|
||
| Name | Description | Type | Labels | ||
| -----|-------------|------|------- | ||
| `windows_filetime_mtime_timestamp_seconds` | File modification time | gauge | `file` | ||
|
|
||
| ### Example metric | ||
|
|
||
| ``` | ||
| # HELP windows_filetime_mtime_timestamp_seconds File modification time | ||
| # TYPE windows_filetime_mtime_timestamp_seconds gauge | ||
| windows_filetime_mtime_timestamp_seconds{file="C:\\Users\\admin\\Desktop\\Dashboard.lnk"} 1.726434517e+09 | ||
| ``` | ||
|
