Re: [omd-users] Migrate from nagios/Checkmk to OMD
Update ( sorry I'm not so good in debug things like that ): I only use the selfcreated localhost.cfg not any other files to exclude some migration error. /omd/sites/SBA/etc/nagios/conf.d\localhost.cfg I tried to run some other forks in my menue. It comes the following errors: checkmk: Cannot connect to 'unix:/omd/sites/SBA/tmp/run/live': [Errno 2] No such file or directory thrurk: SBA: ERROR: failed to open socket /omd/sites/SBA/tmp/run/live: No such file or directory..

Re: [omd-users] Migrate from nagios/Checkmk to OMD
Hello again, The Problem still exist i had made some steps: -Check the nagios config -Created an new instance and set only an test localhost - Checked the apache logs - checked the nagios log Could someone bring me on Track or in the right direction ?

Re: [omd-users] Migrate from nagios/Checkmk to OMD
Hello Again, Now i have a little bit time to set an test-run So what i have done so far: Give the files in /omd/sites/SBATEST/etc/nagios/conf.d the owner from the OMD User. Modified the commands.cfg and the ressource.cfg to the new variables. But i get the error again Error: Could not read host and service status information! So is this an apache problem ?: Here is an outline from the apache.conf: ServerName 127.0.0.1 # OMD OMD OMD OMD OMD OMD OMD OMD OMD OMD OMD OMD # Better do not change anything in this block or you will have to # resolve conflicts in omd cp/mv/upate: ServerRoot "/omd/sites/SBA" PidFile /omd/sites/SBA/tmp/apache/run/apache.pid DocumentRoot "/omd/sites/SBA/var/www" # Include file where TCP port number is configured.

Re: [omd-users] Migrate from nagios/Checkmk to OMD
Hi Jon, Your first step -> copy Nagios files - is not the best idea. Do you have so many classical configured Nagios checks? Migration looks at my systems this way. - integrate all files from /etc/check_mk/conf.d and /etc/check_mk/multisite.d/ to the new OMD side - at this step i don't overwrite the files, i merge these files - copy the autocheck files from /var/lib/check_mk/autochecks to your OMD if you don't want to inventories all hosts again - copy your Nagios state files to the site that the system is starting with the last state from the old system - copy only the plugins what are not included in OMD to ~/local/lib/nagios/plugins - replace all $USER1$ with $USER2$ if the plugin is inside the ~/local/ folder - generate a new check_mk configuration with cmk -R inside your OMD site and test if all is working What is not described here is the migration of PNP data. These depends on the system architecture and storage format of your PNP data. Best regards Andreas schrieb am Mi., 5.
