telegraf-btrfs-exec

Python script that can be used to capture BTRFS information in telegraf

What does it capture

Currently it captures the following information for all the pools mounted at the time of running

$btrfs device stat

  • write_io_errs
  • read_io_errs
  • flush_io_errs
  • corruption_errs
  • generation_errs

$btrfs filesystem df

  • Data (total, used, free)
  • System (total, used, free)
  • Metadata (total, used, free)
  • GlobalReserve (total, used, free)

$btrfs filesystem usage

  • Device_size
  • Device_allocated
  • Device_unallocated
  • Device_missing
  • Used
  • Free_(estimated)
  • Data_ratio
  • Metadata_ratio
  • Global_reserve
  • Data (Per Device)
  • Metadata (Per Device)
  • System (Per Device)
  • Unallocated (Per Device)

Usage

  1. Install and place btrfs.read.py in location accessible by telgraf. For example /etc/telegraf/btrfs.read.py
  2. Grant telegraf permission to sudo btrfs command without password by adding the following to /etc/sudoers
telegraf ALL=(root) NOPASSWD: /usr/local/bin/btrfs
  1. Update /etc/telegraf/telegraf.conf to call the script
 [[inputs.exec]]
   commands = [
     "python /etc/telegraf/btrfs.read.py"
   ]
   timeout = "5s"
   data_format = "influx"

  • python
