Nagios check_icmp For Servers

[abdelhafeth.mzahem]

Dears

We have about 200 windows servers , we put them in one host group Named Win-Servers, we applied a service that monitor the servers ping status named Win-Servers-Ping applied on Win-Servers Host group with specific check settings to send alert to Data center administrators.

We have 2 windows servers in the Win-Servers host group, we add them to other Host Group named Domain-Win-Servers, we applied a service that monitor the ping status of these 2 servers named Domain-Win-Servers-Ping applied on Domain-Win-Servers Host group with same check settings of other ping status service to send alert only to Domain administrator.

We are using check_icmp following command to monitor Servers status for both services command.


$USER1$/check_icmp -H $HOSTADDRESS$ -w $ARG1$,$ARG2$ -c $ARG3$,$ARG4$ -p 5


We make reboot for one of domain servers.

We received that server ping is critical from the service Domain-Win-Servers-Ping but not from Win-Servers-Ping ( Alert sent to Domain admins but not to data center admins).

may the number of devices in host group affect the check status and time ? how check_icmp work on servers in host group ? is it run on host group servers parallel or server by server ?

why alert not received from one service and received from other ?

we tried reboot other time and 2 alerts received , we tried third but only one alert received.

seems some times work and some times not work

please your help.

Can you show us a "sanitized" version of the "Win-Servers" & "Domain-Win-Servers" hostgroup's configs, "Win-Servers-Ping" & "Domain-Win-Servers-Ping" service's configs?

CCM->Host Groups->View Text Config
CCM->Services->View Text Config

Also, show us the configs for the contacts/contactgroups, assigned to these services.

Dear Sir,


the exact Names are as following :

Win-Servers ==>JAW-DC-Win
Domain-Win-Servers ==> SMS-ADV-Win

Data Center Admin Contact Group :- Win_DC_Admins
Server Administrator Contact Group :- SMS-ADV-Admins

[lmiltchev]

The "Ping" service (from the services.txt) is added to only one of the two hostgroups (SMS-ADV-Win)

Code: Select all

define service {
	service_description		Ping
	hostgroup_name			SMS-ADV-Win
	display_name			Ping
	check_command			check-host-alive!

which you received notifications for. My understanding was that the "Ping" service was added to both hostgroups. Can you clarify?

Also, you said:

We make reboot for one of domain servers.

We received that server ping is critical from the service Domain-Win-Servers-Ping but not from Win-Servers-Ping ( Alert sent to Domain admins but not to data center admins).

What is the host that you rebooted? Can you show us the host's config? You don't have any members, listed under the two hostgroups:

Code: Select all

define hostgroup {
	hostgroup_name                		JAW-DC-Win
	alias                         		JAWWAL Windows Servers
	}
	
define hostgroup {
	hostgroup_name                		SMS-ADV-Win
	alias                         		SMS-ADV-Win
	}

Most probably you have these hostgroups added in the host configs...

Code: Select all

define host{
	host_name	host_name
	...
	hostgroups	<hostgroup_names>
	...
   	}
