Disk IO not configured properly

Elastic Stack Beats
1

Hello Team,

I'm trying to add disk IO to metricbeat in system.yml. I'm using AWS EC2. The only option that is causing the problem is DiskIO, when I comment it, metricbeat starts.

Here is my config:

- module: system
  period: 10s
  metricsets:
    - cpu
    - load
    - memory
    - network
    - process
    - process_summary
    #- core
    - diskio:
        include_devices: ["nvme1n1","nvme0n1","nvme2n1p1"]
    #- socket
  process.include_top_n:
    by_cpu: 5      # include top 5 processes by CPU
    by_memory: 5   # include top 5 processes by memory

- module: system
  period: 1m
  metricsets:
    - filesystem
    - fsstat
  processors:
  - drop_event.when.regexp:
      system.filesystem.mount_point: '^/(sys|cgroup|proc|dev|etc|host|lib)($|/)'

- module: system
  period: 15m
  metricsets:
    - uptime

Please help me out here. Please give the exact change that I need to make as I'm new to this.

Regards,
Ash.

Could you share your log file when you start with diskio enabled?

Hello Ruflin,

Here is my metricbeat log:

I hope this helps, I'm sure there is some other way around this.

Hello Ruflin,

I figured it out. Using the command metricbeat test modules, it gave me an error:

Error getting metricbeat modules: error loading config files: invalid config: yaml: line 14: mapping values are not allowed in this context

So, I commented the diskio in that section and created a new one, here is my new system.yml:

# Module: system
# Docs: https://www.elastic.co/guide/en/beats/metricbeat/6.5/metricbeat-module-system.html

- module: system
  period: 10s
  metricsets:
    - cpu
    - load
    - memory
    - network
    - process
    - process_summary
    #- core
    #- diskio
    #    include_devices: nvme1n1
    #- socket
  process.include_top_n:
    by_cpu: 5      # include top 5 processes by CPU
    by_memory: 5   # include top 5 processes by memory

- module: system
  period: 1m
  metricsets:
    - filesystem
    - fsstat
  processors:
  - drop_event.when.regexp:
      system.filesystem.mount_point: '^/(sys|cgroup|proc|dev|etc|host|lib)($|/)'

- module: system
  period: 15m
  metricsets:
    - uptime
    #- diskio
     
- module: system
  metricsets: ["diskio"]
  diskio.include_devices: ["nvme0n1", "nvme1n1","nvme2n1"]

Regards,
Ash.
