Hi,

On all my graphs it seems that nagios is lagging. For example the time is now 17:00

But its only showing up until 16:15... the updates on this is to poll every 5 mins. its happening to all my graphs on my dashboard. The VM nagios is running on seems fine. No issues with the monitoring engine.

Any ideas?

Is your nagios server setup on ntp? Are the scheduled checks that are being scheduled now, also at this lagged time? Can you run the commands below please.

cat /etc/localtime
grep -i 'date.timezone' /etc/php.ini

Thing is its ok now, but towards the end of day this happens. For instance at this moment it looks ok, just gets further and further behind.

LMTBSTGMTBDST
GMT0BST,M3.5.0/1,M10.5.0

[root@nagios ~]# grep -i 'date.timezone' /etc/php.ini

date.timezone = Europe/London

2 possible things:

1. there will be a lag if you have setup RRDCACHED

2. If not we should check the following when you are experiencing this

Code: Select all

ll /usr/local/nagios/var/spool/xidpe | wc -l
ll /usr/local/nagios/var/spool/perfdata | wc -l
tail /usr/local/nagios/var/npcd.log
tail /usr/local/nagios/var/perfdata.log

I've never knowingly enable it so I did what you said. The logs were massive so I zipped them up.

[root@nagios ~]# ll /usr/local/nagios/var/spool/xidpe | wc -l
3

[root@nagios ~]# ll /usr/local/nagios/var/spool/perfdata | wc -l
8
