Re: [Nagios-devel] Nagios and Gearman - huge environment performance problem

[Rodney R. <rod...@gm...>]

Hi Sven. Thank you again. I´m pretty sure that my check interval is 15 min,
for both, hosts and services. I´ve set this in the templates.cfg file (see
below). I sending too the nagiostats output. I agree with you that if we
divide 100 k checks / 15 min ~ 111 checks/sec, but the problem is that
Nagios does not make these checks smoothly during the time. Thats the
problem.

define host{
        name                            generic-host
        ...
        check_interval          15
        ....
}

define service{
        name                            generic-service
        ...
        normal_check_interval           15
        ....
}
