Device check-time reset on process restart

[NagAlf]

Hi!
I've in Nagios list one (server) device (first in host detail list as by name) which control-times is always reset when I restart Nagios processes. Something I missed?
More thanks, Alar.

control-times

Could you clarify?

Hi and thanks!
Ok, I'm trying to.
When I click on Host Detail (in Monitoring section on left side) then all hosts appear nicely and 4-th column is as Duration. I see there some servers 83 days up (since I start using Nagios), some ws's just a few hours after morning start etc. And this does not change (for most of hosts) when I restart Nagios service. That's ok. But there is one server (which is up 24x7) which Duration starts from 0 every time I restart Nagios service. It's listed as first (alphabetically). Don't know why this happen in Nagios with this host.
More thanks, Alar.

So basically all of your hosts but one, properly show uptime, or last state change times. However one of them seems to reset to 0 every time you restart the nagios daemon.

Have you done any optimizations such as creating an objects.precache file?
What type of a host check is the problematic host using to verify uptime?
Are any other hosts\services doing this same check?
If so are they also having the same effect?

Hi and thanks!
Yes, all but one. Nope, no optimization, at least I'm aware of. In description it should and does check only device up/down, no services to check. Yes, I've also other devices described in such a way (most of those), no problems.
More thanks, Alar.

Can you post the check and the command definitions of a check that does work, and one that doesn't?

[NagAlf]

Hi and thanks!
Nothing much, really. First one does work wo clearing time, another not. Changed positions, same. (I've changed names and IP's etc. below.)
define host{
use linux-server ; Name of host template to use
host_name IPtrykk
alias iTrykk
address <ip>
}
define hostextinfo{
host_name IPtrykk
action_url http://<>
icon_image x.png
}

define host{
use linux-server ; Name of host template to use
host_name FAILER
alias Failer
address <ip>
}
define hostextinfo{
host_name FAILER
action_url http://<>
icon_image x.png
}
More thanks, Alar.

Hmm, so nothing different between them there, just for completeness, could you post the linux-server template. Also what version of core are you running?

[NagAlf]

Hi and thanks!
define host{
name linux-server ; The name of this host template
use generic-host ; This template inherits other values from the generic-host template
check_period 24x7 ; By default, Linux hosts are checked round the clock
check_interval 5 ; Actively check the host every 5 minutes
retry_interval 1 ; Schedule host check retries at 1 minute intervals
max_check_attempts 10 ; Check each Linux host 10 times (max)
check_command check-host-alive ; Default command to check Linux hosts
notification_period workhours ; Linux admins hate to be woken up, so we only notify during the day
; Note that the notification_period variable is being overridden from
; the value that is inherited from the generic-host template!
notification_interval 120 ; Resend notifications every 2 hours
notification_options d,u,r ; Only send notifications for specific host states
contact_groups admins ; Notifications get sent to the admins by default
register 0 ; DONT REGISTER THIS DEFINITION - ITS NOT A REAL HOST, JUST A TEMPLATE!
}
Ja-jaa, I'm using Nagios version 3.0.6, bundled with SLES 11. Jah, I know. =)
More thanks, Alar.

Hi again!
Well, tried to rename this host (in cfg-file), changed IP-address, changed template to use, even moved it to another group file (into windows.cfg) etc., but still ... .Odd!
