[op5-users] Passive checks with op5 Monitor

[Mattias Ryrlén]

Hi, this is a english list :)

I have another funny solution for distributed sync.

Using syslog to send data to Master server. this doesn't include sync of
config but you get the passive data.

Then you have to have some checks of freshness and stuff like that to.


******** Scripts ********
- sync_udp_parser.sh (can be obtained, reading from the pipe and copy to
nagios pipe, prob need to redo this script since i have seen it die on
my installation some times, prob a simple loop will do it.)
- sync_udp_send.sh (can be obtained, more or less using logger with
preformatted nagios PASSIVE HOST/SERVICE format)

******** ServerA (Poller) ********
The server doing the actual polling.

******** Config ********
* Place sync_udp_send.sh to passive directory
/opt/monitor/op5/passive/

** nagios.cfg
  - obsess_over_services=1
  - obsess_over_hosts=1
  - ocsp_command=sync_send_udp_service
  - ochp_command=sync_send_udp_host
(you may also need to verify that you have obsess_over_[services/hosts]
enabled in your specific templates)

** misccommands.cfg
# command 'sync_send_udp_host'
define command{
    command_name                   sync_send_udp_host

command_line                   /opt/monitor/op5/passive/sync_udp_send.sh
host $TIMET$ $HOSTNAME$ $HOSTSTATE$ '$HOSTOUTPUT$'
    }

# command 'sync_send_udp_service'
define command{
    command_name                   sync_send_udp_service

command_line                   /opt/monitor/op5/passive/sync_udp_send.sh
service $TIMET$ $HOSTNAME$ $SERVICESTATE$ '$SERVICEOUTPUT$'
'$SERVICEDESC$'
    }

* syslogd
edit /etc/syslog.conf
local6.*                    @<ip of ServerB>

service monitor configtest

if everything went ok.
service monitor reload







******** ServerB (Master) ********
The server that recive the passive result

******** Config ********
* Create pipe for passive syslog udp messages.
mknod /opt/monitor/op5/passive/sync_udp.pipe p
chmod 600 /opt/monitor/op5/passive/sync_udp.pipe 

* Place pipe parser (sync_udp_parser.sh) to passive directory
/opt/monitor/op5/passive/

* Start parser
/opt/monitor/op5/passive/sync_udp_parser.sh
< /opt/monitor/op5/passive/sync_udp.pipe &

* syslogd
edit /etc/syslog.conf
local6.*                        |/opt/monitor/op5/passive/sync_udp.pipe
