I got error high CPU,
Cat file config as follow:
storage:
dbPath: /var/lib/mongodb
journal:
enabled: true
wiredTiger:
engineConfig:
cacheSizeGB: 5
systemLog:
destination: file
logAppend: true
#path: /var/log/mongodb/mongod.log
path: /storage/mongodb/log/mongod.log
logRotate: reopen
net:
port: 27017
#bindIp: 127.0.0.1
bindIp: 0.0.0.0
processManagement:
timeZoneInfo: /usr/share/zoneinfo
Looks like there are a lot of python3 processes running on this host and they are taking up all the CPU (mongod process has mere 6.5%) so you may need to look at those rather than your MongoDB set-up.

The first, thank you for your feedback!
That right, I had a lot of python3 processes in my server.
My script are simple, Initiate connection to, then update a lot of field in collection of db, then close session. I schedule them every 1 hour and I observed CPU increase over time. CPU goes down when I restart mongod service. Looking at the htop result, mongodb are taking up all the CPU.
Did I do something wrong in my script?
Is there a way to limit CPU for mongod service?
Or show me how to test and solve this problem.
Thanks for the help!
