Check system statistics

Host resource usage
To check the CPU, memory, and disk usage on a Linux machine, you can run the following command.
$ sudo echo -n "CPUs: ";cat /proc/cpuinfo | grep processor | wc -l; echo -n "Mem: ";free -h | grep Mem | tr -s " " | cut -d" " -f 2; echo -n "Disk: "; df -h / | grep -v Filesystem;
CPUs: 72 Mem: 251G Disk: /dev/sda2 160G 13G 148G 8% / 10.1.12.104 CPUs: 88 Mem: 251G Disk: /dev/sda2 208G 22G 187G 11% / 10.1.12.105 CPUs: 88 Mem: 251G Disk: /dev/sda2 208G 5.1G 203G 3% /
Generally, common tools like
iostat may be useful.
top reports high CPU usage for the
auditd process, it may have some rules auditing some system calls frequently used YugabyteDB which can significantly affect performance. You can try temporarily disabling
audit by running (on each YugabyteDB node).
$ auditctl -e 0
and check if this improves performance.
To re-enable it afterwards, run:
$ auditctl -e 1
YugabyteDB processes state
YugabyteDB provides web endpoints where the current state of each process is aggregated. This includes logs, flags as well as memory, disk, and network usage metrics. Additionally, it provides dedicated metrics endpoints for YCQL and, respectively, Redis requests.
