mongod process taking more CPU. Getting below message in var/log/splunk/mongod.log. Where should I run this command?
Is there any alternate solution?

WARNING: You are running on a NUMA machine.
We suggest launching mongod like this to avoid performance problems:
numactl --interleave=all mongod [other options]

bash-4.1$ pwd
/export/apps/splunk/bin
bash-4.1$ ls -lrt mongod
-r-x------ 1 a_splnkd 5001 24168096 Mar 26 12:45 mongod
bash-4.1$ numactl --interleave=all mongod
numactl: execution of `mongod': No such file or directory

as its saying, `mongod': No such file or directory, please try -

numactl --interleave=all ./mongod

numactl --interleave=all /export/apps/splunk/bin/mongod

mongod process taking more CPU -- maybe, its a mongodb related issue. please verify.

We are not using any mongodb on the system. Warnings is from splunk mongod.log. Do you know why this mongod coming in picture. We are using HF for DB2 connect for ORACLE DATABASE.

/export/apps/splunk/var/log/splunk/mongod.log

bash-4.1$ numactl --interleave=all ./mongod
