How to log/save all commands in CentOS One of the easy ways to log/save/record all issued commands by users is setup logger. I use rsyslog. 1. Add at the end of /etc/bashrc export PROMPT_COMMAND='RETRN_VAL=$?;logger -p local6.debug "$(whoami) [$$]: $(history 1 | sed "s/^[ ]*[0-9]\+[ ]*//" ) [$RETRN_VAL]"' if you want to log also IP use this (I know it is not perfect if there are few the same users connected from different IPs) export PROMPT_COMMAND='RETRN_VAL=$?;logger -p local6.debug "$(w -i -h| grep -Eo "[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}" ) : $(history 1 | sed "s/^[ ]*[0-9]\+[ ]*//" ) [$RETRN_VAL]"' Output will be like this: date time server-name user-name: IP address : command Jul  7 13:36:45 server1 root: 192.168.0.5 : 07/07/16 13:36:38 ls -la [0] 2.  Create new config file at: /etc/rsyslog.d/bash.conf and put inside: local6.*    /var/log/logger.log 3. Restart syslog systemctl

Graphs shows no data - Observium Probably cron does not work. Manual recommends using these: 33 */6 * * *   root    /opt/observium/discovery.php -h all >> /dev/null 2>&1 */15 * * * *   root    /opt/observium/discovery.php -h new >> /dev/null 2>&1 */15 * * * *   root    /opt/observium/poller-wrapper.py 2 >> /dev/null 2>&1 it will not work when edited using crontab -e Create new file in /etc/cron.d/observium and paste there. If still does not work try this: 33 */6 * * *   root    cd /opt/observium/ && ./discovery.php -h all >> /dev/null 2>&1 */15 * * * *   root    cd /opt/observium/ && ./discovery.php -h new >> /dev/null 2>&1 */15 * * * *   root    cd /opt/observium/ && ./poller.php -h all >> /dev/null 2>&1 If still does not work, try to add above cron entries into /etc/crontab and restart cron service.
