# filestat Input Plugin

The filestat plugin gathers metrics about file existence, size, and other stats.

### Configuration:

```toml
# Read stats about given file(s)
[[inputs.filestat]]
  ## Files to gather stats about.
  ## These accept standard unix glob matching rules, but with the addition of
  ## ** as a "super asterisk". See https://github.com/gobwas/glob.
  files = ["/etc/telegraf/telegraf.conf", "/var/log/**.log"]
  ## If true, read the entire file and calculate an md5 checksum.
  md5 = false
```

### Measurements & Fields:

- filestat
    - exists (int, 0 | 1)
    - size_bytes (int, bytes)
    - modification_time (int, unix time nanoseconds)
    - md5 (optional, string)

### Tags:

    - file (the path the to file, as specified in the config)
