Nagios Support Forum

Good Morning,

I have Centos 7 with Nagios Core 4.4.1 and 0.626 pnpnagios with 60 hosts between Windows computers, servers, switches, etc; but I have the problem for a long time that when a computer is turned off or disconnected from the network .. I receive the notification and see on my map by the nagvis of the fall of the computer, but in my pnpnagios the sector of lost packages does not show any activity.

I would be grateful if you would confirm me if I would be well installed by supporting me in confirming your configuration.

I have already reinstated in pnpnagios twice in two different ways, but I always have the same result, when a computer is disconnected there is no activity in the second graphic of packages lost.

I have also followed the following link without success:

If a host is down there is no data for the graphing to log

Dear Scottwilkerson, I was referring to the second graphic of lost packets .. when the host loses connectivity you should see activity in this part ..

I would want to see the output from the host detail page for this check, specifically these 3 lines

Dear Scottwilkerson,

Best regards,

I guess I was referring to what is reported in the Performance Data: field during the time when you don't have any performance data.

I am guessing, that for some reason the check is timing out before it can get the data.

This maybe can be rectified by adjusting the check to make sure it doesn't timeout before the 30 second limit

This is the configuration my host has .. you could confirm which field I should change please.

define host{
use servers,host-pnp
host_name host
alias host
address 192.168.1.204
check_command check-host-alive
check_interval 2
check_period 24x7
max_check_attempts 1
retry_interval 1
notifications_enabled 1
notification_period 24x7
notification_options d,u,r,s
contact_groups admins
}

Can you show the command definition for check-host-alive?

It is attached as requested:

define command {

command_name check-host-alive
command_line $USER1$/check_ping -H $HOSTADDRESS$ -w 3000.0,80% -c 5000.0,100% -p 5
}

Are you sure this is the same host?

I ask because in the state history you showed earlier it showed the check timed out after 30 seconds but check_ping default plugin timeout is 10 seconds if one isn't specified with -t
