I have already setup nagios which is working fine. It can monitor my
localhost and window box perfectly with default configs provided.
Can anyone help me to setup/monitor unix host? I have these things ready
with me
template.cfg,
define host{
name redhat-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!
}
redhat5.cfg,
define host{
use redhat-server
host_name redhat5.remotehost.com
alias Redhat5 Remote Host
address 172.17.38.201
contact_groups admins
}
# HOST GROUP DEFINITION
# Define an optional hostgroup for Linux machines
define hostgroup{
hostgroup_name redhat-servers ; The name of the hostgroup
alias Linux Servers ; Long name of the group
members redhat5.remotehost.com ; Comma separated list
of hosts that belong to this group
}
define service{
use generic-service
service_description Root Partition
contact_groups admins
check_command check_nrpe!check_disk
}
define service{
use generic-service ; Name of
service template to use
host_name redhat5.remotehost.com
service_description Current Users
check_command check_nrpe!check_users!20!50
}
Thanks,
Nilesh
