3-You can run nmon for your Linux Distrubition here without installation.
Press key you want to monitor.
Note : Press dot ( . ) to not see free resource.
For example press d for Disk and then . to see only working disks. Same for all other resources.
Sample Screen
Press m ( Memory ) + n (Network) + d (Disks ) + . ( dot)
I have prepared NMON Performance data collection steps which will collect nmon performance data every day. this will help us to see past server performance report.
sudo rpm -ivh /tmp/nmon-16g-3.el7.x86_64.rpm
sudo mkdir -m 755 -p /var/nmon/data
sudo touch /var/nmon/nmon_cron.sh
echo ‘#!/bin/sh’ |sudo tee -a /var/nmon/nmon_cron.sh
echo ‘cd /var/nmon/data’ |sudo tee -a /var/nmon/nmon_cron.sh
echo ‘nmon -f -t -s 120 -c 720’ |sudo tee -a /var/nmon/nmon_cron.sh
echo ‘#compress files older than two days’ |sudo tee -a /var/nmon/nmon_cron.sh
echo ‘find /var/nmon/data -name “*.nmon” -mtime +1 -print -exec gzip {} \;’ |sudo tee -a /var/nmon/nmon_cron.sh
sudo chmod +x /var/nmon/nmon_cron.sh
sudo sh /var/nmon/nmon_cron.sh
sudo crontab -u splunk -l >>/tmp/crontab-bkp
sudo crontab -u root -l >>/tmp/crontab-bkp
sudo crontab -u splunk -l | { cat; echo “01 00 * * * sudo sh /var/nmon/nmon_cron.sh 2>/dev/null”; } | crontab
