Dear Expert

Yesterday we added some Hosts (without any services), showing correct status UP/DOWN but there is no uptime (no duration) as below, what could be reason?

Status Details
Host State: Up
Duration: N/A
Host Stability: Unchanging (stable)
Last Check: 16/02/2015 09:10:07
Next Check: 16/02/2015 09:15:07

I tried with Ping This Host ,, Immediate Check ,, but still no duration (no uptime).

define host {
host_name myhostname
use xiwizard_switch_host
alias myhost alias
display_name myhost displayname (192.168.55.66) myref
address 192.168.55.66
max_check_attempts 1
check_interval 5
retry_interval 1
check_period xi_timeperiod_24x7
contact_groups alert_group
notification_period xi_timeperiod_24x7
notification_options d,r,f,
notifications_enabled 1
icon_image switch.png
statusmap_image switch.png
_xiwizard switch
register 1
}

Do you see a duration if you log in Nagios Core?

Code: Select all

http://ip address/nagios

Try restarting services:

Code: Select all

service nagios stop
killall nagios
service ndo2db stop
service ndo2db start
service nagios start

If this doesn't help, post the nagios.cfg.

Dear lmiltchev

Yes, I can see duration from /nagios
Host Status:
UP
(for 0d 7h 41m 40s+)

If its well known bug, please fix it.

You have suggested to restart the services but I will not do as me afraid for something goes wrong (will try later)

However please let me know to stop/start services, killall nagios, how safe? Yes, sure, there will be some interruptions for some seconds but it cause any database corruption? This me asking as whenever we found Nagios hung, we do this, how long its safe? Any adverse affect other than some seconds interruption?

Well, the issue must be on the XI/NDO side.
Check the system date for good measure:

Code: Select all

date
grep timezone /etc/php.ini

Check /var/log/messages for failed queries:

Code: Select all

grep query /var/log/messages | tail

Any db errors?

Code: Select all

tail -25 /var/log/mysqld.log

Dear abrist

Please note UP Time showing for all the Host, except very few, DATE is correct, all performance graph, alert, notification date/time is okay.

The date of the log entry. (YYMMDD)
What was the output of the queery grep:

Code: Select all

grep query /var/log/messages | tail

Is you db offloaded? If not, try restarting mysql:

Code: Select all

service mysqld restart

We may have to increase debugging on ndo and check the queries. Are you currently logging anything from ndo?

Code: Select all

Hello

I have two servers with pretty same name.
I did compare those two servers in nagios_hostatus table and found following difference:
last_check next_check check_type last_state_change last_hard_state_change last_hard_state last_time_up last_time_down
2/19/2015 8:58 2/19/2015 9:00 0 12/15/2014 0:30 12/07/2014 9:45 0 2/19/2015 8:58 12/15/2014 0:30
2/19/2015 8:58 2/19/2015 9:00 0 12/31/1969 19:00 12/31/1969 19:00 0 2/19/2015 8:58 12/31/1969 19:00

As you can see following fields are not going update:
last_state_change last_hard_state_change last_hard_state last_time_up last_time_down

But I submitted custom passive check result with host state DOWN.
On the scheduled check it come UP with normal status of UP but starting from time of submitted passive check with DOWN state.

Looks like is some bug some where.
It is happened first time with me.

In your nagios.cfg what is the following set to

Code: Select all

log_initial_states

If it is set to 1, I believe it will resolve the issue when adding new hosts. This may not affect previously created hosts

Posted: **Thu Feb 19, 2015 9:16 am**

It has 0 value

Question.

I make some test:
I changed to have initial state in host = "d" instead of "o" and added new host - everything goes perfect and I get uptime duration right away.
Can you please confirm that my steps can resolve this issue?

Thanks
