Message : UXMON: Too many instances: ntpd . ARGS: -p /var/run/ntp/ntpd.pid -x -g -u ntp:ntp -i /var/lib/ntp -c /etc/ntp.conf
Msg Group : OS

Instruction : No

When there are two ntp processes, review your /etc/ntp.conf file. There must be an unreachable NTP server

root@linux:~ # ps -ef | grep ntp
root 24639 24476 0 10:22 pts/0 00:00:00 grep ntp
ntp 26152 1 0 Sep11 ? 00:00:06 /usr/sbin/ntpd -p /var/run/ntp/ntpd.pid -x -g -u ntp:ntp -i /var/lib/ntp -c /etc/ntp.conf

Review your /etc/ntp.conf file and restart NTP

root@linux:~ # service ntp stop

root@linux:~ # ps -ef | grep ntp

Enable NTP statistics

Edit file /etc/ntp.conf

#Enable NTP statistics
statsdir /var/log/ntpstats/
statistics loopstats peerstats clockstats
filegen loopstats file loopstats type day enable
filegen peerstats file peerstats type day enable
filegen clockstats file clockstats type day enable

Restart ntp service. If it shows the following message, the directory /var/log/ntpstats has wrong permissions

May 21 14:56:40 linux ntpd[11202]: can’t open /var/log/ntpstats/peerstats.20150521: Permission denied

ntpd is running under user ntp

root@linux:~ # ps -ef | grep ntp
ntp 31445 1 0 15:05 ? 00:00:00 ntpd -u ntp:ntp -p /var/run/ntpd.pid -g

Change the permission as needed

root@linux:~ # ls -ld /var/log/ntpstats

Took a look at the log file and it was showing that is a problem with NTP

Apparently it is not synchronizing with more than one peer

Restart NTP

Then checking again the results
