### 4.3. Textfile Metrics
|
||||||
|
|
||||||
|
For more flexibility the exporter also allows exporting metrics collected from a text file.
|
||||||
|
|
||||||
|
To enable textfile metrics:
|
||||||
|
1. Enable the collector with `-collector.textfile=true`
|
||||||
|
2. Provide the directory to read files from with the `-collector.textfile.directory` flag
|
||||||
|
|
||||||
|
Metrics collected from these files will be exposed directly alongside the other metrics without any additional processing.
|
||||||
|
This means that it is the responsibility of the file creator to ensure the format is correct.
|
||||||
|
|
||||||
|
By exporting textfile metrics, an extra metric is also exported with an error count for each file:
|
||||||
|
|
||||||
|
```
|
||||||
|
# HELP textfile_error Checks for errors while reading text files
|
||||||
|
# TYPE textfile_error gauge
|
||||||
|
textfile_error{path="file.prom"} 0
|
||||||
|
```
|
||||||
|
|
||||||
|
**NOTE:** Only files ending with `.prom` will be considered.
