# ============================= X-Pack Monitoring ==============================

# reporting is disabled by default.

# Set to true to enable the monitoring reporter.
#monitoring.enabled: false

# Uncomment to send the metrics to Elasticsearch. Most settings from the
# Elasticsearch outputs are accepted here as well.
# Note that the settings should point to your Elasticsearch *monitoring* cluster.

Hi @Vivek_Chaturvedi Welcome to the community...

Hmmm line 32 and below wrongly indented YAML is code and very sensitive to proper indenting.

Look how the icmp is indented and follow that.

There are many online YAML validators perhaps you should try one

I plugged your into this one..

And showed right where the problem is with a good description

BTW I formatted your code which you should do 3 ``` before and after your code.

Thank you that helped me !!
