problems with distributed monitoring

[Dmitriy Kirhlarov]

Hi!

We are trying to implement distributed monitoring scheme with snmp and passive checks, in general.

For transfering passive checks results from a client to "monitoring" nagios we use nsca without crypting (BTW, nsca-2.4 can't be compiled without libmcrypt. We had be write a patch)
Data are transfered every min.

"Monitoring" nagios has oscp_command set to script, which puts data to "to_send.dump" file. Every 30 sec other script transfers accumulated data from the "to_send.dump" file to "central" nagios via nsca over ssh-forwarded port.

All work fine on the "monitoring" nagios. All services "OK".
But, on "central" nagios most part of services are in flapping and/or unknown status.
As I can see, those services was configured as active checks on "monitoring" nagios.

My templates:
on "monitoring" nagios:
-----
define service{
        name                            generic-service
        register                        0
        is_volatile                     0
        max_check_attempts              1
        normal_check_interval           1
        retry_check_interval            1
        check_period                    24x7

        notifications_enabled           0
        contact_groups                  admins
        }
define service{
        use                             generic-service
        register                        0
        name                            minfra01-active
