Nagios Support Forum

Hi Support,
My Nagios XI was working fine. But from few hours accidently its showing alert notification duration is -ve values ie (-4seconds). I have not made any configuration changes on the server. Can anyone please suggest how to fix this issue..

Thanks,
Jyoti

When you navigate to Admin -> System Profile -> Show Profile, what is the PHP Time and System Time set to? They will need to be in sync.

Additionally, what is the result of df -h?

Hi Please find the output

What version of the Operation Center are you running? You can find this under the Admin --> System Extensions --> Manage Components menu.

Operation centers version is 1.0.2.
This issue is not just with Operations center, Home -> Details ->Service details and Home -> Details ->host details also shows time duration in -Ve value.

Let's see these three commands ran around the same time:

[root@nagios~]# date
Tue Jan 19 09:57:16 PST 2016
[root@nagios~]# mysql -unagiosxi -pn@gweb -e "SELECT NOW();"
ERROR 1045 (28000): Access denied for user 'nagiosxi'@'localhost' (using password: YES)
[root@nagios~]# php -r "echo date('r').PHP_EOL;"

Few days back we have offloaded the DB to remote server. is this issue due to this offloading?

It's certainly a possibility. is there a lot of latency between the two locations?

How can I check the latency between these 2 locations?

With the ping command.
