service checks interval

[crsurf]

Re: [Nagios-users] service checks intervalI´m interested to know the problem
before users notify this for me or to administrator, and in some criticial
services for business, in most cases the users notify the administrator
before monitoring system, in case of this services are being checked at an
interval of 5 or 10 minutes.
I not see correlation in service check interval with time to correct a
problem, a problem correction depends of the problem, in some cases a
service restart is sufficient to solve a problem, but when a disk crash, the
time to resolve this problem is much largest.

  I have to ask. What could you possibly do in 5 seconds to correct any
failure situation that you might discover monitoring at that frequency.
IMHO, you interval sould never be shoerter than the minimum time to correct
a problem.

  What could you possibly be interested in at 5 second intervals?

  Hello

          I already read and re-read documentation about the parameters
  service_interleave_factor, normal_check_interval, freshness_treshould,
  status_update_interval, command_check_interval, sleep_time,
  inter_check_delay_method, service_reapear_frequency,
  freshness_check_interval and other timeouts parameters.

          I test with some values based on number of services and hosts and
I test
  too using "s" (smart) in inter_delay_check_method and
  service_interleave_factor. But the interval in which a service was checked
  are some variant values betwen 10 and 20 seconds.

          I´m suposing a hipotetical situation that I have to monitoring
critical
  services in a LAN enviroment and I using Nagios in a box with P4-1.8GHz
  processor with 128 MB of RAM, the minumum interval of fresh information in
  theory is the status_update_interval parameter, that have a minimum of 5
  seconds, I´m correct or wrong about this?

          What values I have to use to guarantee this minimum interval of 5
seconds
  or at least 10 seconds,?

          This is possible?


          Sorry about my poor english, I´m trying to improve it and not
sleep. :)
