The CDF Doctor can be used to perform a series of diagnostic checks at the cluster and node level
On any node, run the following command to perform the diagnostic checks:
- $CDF_HOME/tools/cdf-doctor/cdf-doctor cluster check

CDF doctor can be used to generate a dump file containing cluster and node information.
On any node run the following command to generate a dump file:
- $CDF_HOME/tools/cdf-doctor/cdf-doctor cluster dump

You can configure the parameters that can configure certain diagnostic checks.
To configure diagnostic check parameters, edit the following file:
- $CDF_HOME/tools/cdf-doctor/cfg/checkpoint_cdf.json

Default: $CDF_HOME = /opt/cdf/bin
