Subject: Using service dependencies

Hi,

 

I'm trying to use service dependencies as part of my nagios config.

 

Basically, I want to do 2 checks, the primary check connects to a database. The secondary check is for RAM usage.

However, if the primary check fails I don't want nagios to try and attempt the secondary check as there is no point if

a system is down. I still want to see Nagios alert via the web front-end but not be notified via email when the primary check

is in a Unknown or Critical state.

 

(The plugins on their own all work fine thru nagios as do they via the command-line. )

 

I've defined below what I understand to be the way to configure dependencies but i'm not convinced its right even though

it works fine. Could someone take a look and just sanity check this for me and let me know if i'm doing the right/wrong thing ?

 

thx

PS All of the lines below currently sit in my services.cfg until I know it works and then i'll split the dependency to a different cfg file.

Its easier to make changes that way!

 

 

# device1 Primary check
define service{
        use                     generic-service            ; Name of host template to use

        host_name               ngcp4
        service_description     device1 DB Check
        is_volatile                     0
        check_period                    24x7
        max_check_attempts              3
        normal_check_interval           5
        retry_check_interval            1
        contact_groups                  linux-admins
        notification_interval           20
        notification_period             24x7
        notification_options            u,c,r
        check_command           check_wx2_conn!dummy$!device1
        }

 

# device1 Secondary check
define service{
        use                     generic-service
        host_name               ngcp4
        service_description     DB RAM checks for device1
        is_volatile             0
        check_period            24x7
        max_check_attempts      3
        normal_check_interval   5
        retry_check_interval    1
        contact_groups          linux-admins
        notification_interval   5
        notification_period     24x7
        notification_options    u,w,c,r
        check_command           check_wx2_ram!$HOSTALIAS$
        }

 

# device1 dependency checks
define servicedependency{
        host_name                       ngcp4
        service_description             DB RAM checks for device1
        dependent_host_name             ngcp4
        dependent_service_description   device1 DB Check
        execution_failure_criteria      u,c
        notification_failure_criteria   u,c
        }
