How well does it scale? strange udp sync setup.

[Mattias Ryrlén]

Hi,

I have a strange solution setup for a Master/Poller setup. was wondering
if someone can see any performance issue with this setup.

You are only allowed to poll one-way udp, so i thought.. why not use
syslog/logger to send the data.

using centos syslog (not syslog-ng).

******** Scripts ********
- sync_udp_parser.sh (can be obtained, reading from the pipe and copy to
nagios pipe)
- 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 $TIMET$ $HOSTNAME$ $SERVICESTATE$ '$SERVICEOUTPUT$' '$SERVICEDES
C$'
    }

* 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
