I can start from scratch if only there is some step-by-step tutorial, but nowhere is mentioned what i actually need to install and
configure on remote site Nagios server.
All instructions are just simple change in OMD server configuration and everything works like a charm…

Maybe I need to patch Nagios for livestatus to work?
I got information that it might be the case, I don’t know…

I did that, but now I have another error:
Unhandled exception: Malformed output. Livestatus TCP socket might be unreachable.
This is from OMD:
service livestatus
{
type = UNLISTED
socket_type = stream
protocol = tcp
port = 6557
wait = no
limit to 100 connections per second. Disable 3 secs if above.
cps = 100 3
set the number of maximum allowed parallel instances of unixcat.
Please make sure that this values is at least as high as
the number of threads defined with num_client_threads in
etc/mk-livestatus/nagios.cfg
instances = 500
limit the maximum number of simultaneous connections from
one source IP address
per_source = 250
Disable TCP delay, makes connection more responsive
flags = NODELAY
user = nagiosadmin
server = /usr/bin/unixcat
server_args = /usr/local/nagios/var/rw/live
configure the IP address(es) of your Nagios server here:
only_from = 127.0.0.1 10.0.20.1 10.0.20.2 172.16.212.9
----------------------------------------------------------
These parameters are handled and affected by OMD
Do not change anything beyond this point.
Disabling is done via omd config set LIVESTATUS_TCP [on/off].
Do not change this:
disable = no
TCP port number. Can be configure via LIVESTATUS_TCP_PORT
port = 6557
Paths and users. Manual changes here will break some omd
commands such as ‘cp’, ‘mv’ and ‘update’. Do not toutch!
user = monitoring
server = /omd/sites/monitoring/bin/unixcat
server_args = /omd/sites/monitoring/tmp/run/live
----------------------------------------------------------
}
This is from Nagios before i coppied it from OMD:
service livestatus
{
type = UNLISTED
port = 6557
socket_type = stream
protocol = tcp
wait = no
limit to 100 connections per second. Disable 3 secs if above.
cps = 100 3
set the number of maximum allowed parallel instances of unixcat.
Please make sure that this values is at least as high as
the number of threads defined with num_client_threads in
etc/mk-livestatus/nagios.cfg
instances = 500
limit the maximum number of simultaneous connections from
one source IP address
per_source = 250
Disable TCP delay, makes connection more responsive
flags = NODELAY
user = omdadmin
server = /usr/bin/unixcat
server_args = /var/lib/nagios/rw/live
configure the IP address(es) of your Nagios server here:
only_from = 127.0.0.1 10.0.20.1 10.0.20.2 10.7.11.44
disable = no
}

And now it is the same as on OMD with error I mentioned in first sentence in this post…
I can’t find what’s wrong, probably those parameters you mentioned: server, server_args or user…
Kind regards,

Hi Stjepan,
I guess you don’t have livestatus configured in xinetd on Nagios server, do you?
You can take the content of (on your OMD server) ~/etc/mk-livestatus/xinetd.conf, paste it to a xinetd conf file on your Nagios server (e.g. /etc/xinted.d/livestatus) and tweak it to your needs (at least port, user, server and server_args).
After a xinetd restart the connection to livestatus should work - as long as there are no other stones on your network way, e.g. lokal or network firewalls, routing, whatever…
HTH,
Marcel

Hello,
I am having trouble setting up OMD Distributed monitoring multisite.
On one server I have clean instalation of OMD, on other server I have Nagios instalation with couple of devices being monitored.
What do I need to set up or install on Nagios Server for Distributed monitoring to work?!
What do I need to set up or install on OMD Server for Distributed monitoring to work?!
I did everything from OMD side (enable distributed monitoring, set up TCP port towards Nagios server IP address and port 6557, but every time get error:
Nagios server - Livestatus error
Cannot connect to ‘tcp:ipaddress_of_host:6557’: [Errno 103] Software caused connection abort
I am trying to make this work for couple of weeks, been installing check_mk, livestatus, etc. But nothing helps, every time sam error and no second nagios hosts in OMD.
Checking for TCP connection between OMD and Nagios host works just fine, I have tested it.
This is configuration part on OMD server
multisite.mk
sites = {
connect to local Nagios
“monitoring” : {
“alias” : “monitoring”
},
connect to remote site
“scnag”: {
“alias”: “Nagios Server”,
“socket”: “tcp: ipaddress_of_host:6557”,
“url_prefix”: “http:// ipaddress_of_host /”,
},
}

Stjepan
