[omd-users] Migrate from nagios/Checkmk to OMD
OMD omd-2.11.20161004-labs-edition Nagios 3.5 Checkmk 1.2.6p12 Hello Community, Where trying to migrate from our Nagios/Check_mk system to OMD. I think the most business is done with copy&paste some config files. Here is my approach: Change to instance OMD[mysite] with sudo su - mysite Nagios Files: Cfg Files: Copy all cfg Files and the ( nagios.cfg) from old nagios folder /etc/mysite to /etc/nagios/ and ~conf.d Plugins: Copy all PLugins from usr\local\nagios\libexec to ~/local/lib/nagios/plugins Change the owner to omd standard mysite:mysite check_mk Files: OMD[mysite]:~/etc/check_mk i don't know exaclty which i should replace and which should be kept. I will be great if someone can give me some advices which files are crtitical or shouldnt replaced with the old ones. regards john ___ omd-users mailing list omd-users@lists.mathias-kettner.de http://lists.mathias-kettner.de/mailman/listinfo/omd-users

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.

Hello Andreas First of all ... thanks for the infos how do you merge ? with rsync ? i would like a tool which i can choose to keep the original ones unmodified. > do you have so many classical configured Nagios checks? jep we have many classic checks. >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 Beside the fact the we don't have many checkmk checks ( it's still for supporting nagios.. may to replace some checks in future ) i think i can skip these step. >copy your Nagios state files to the site that the system is starting with >the last state from the old system. The state file is also not critical... what it counts is the actual state but i think i still copy these one .. it's the status.dat .. am I right ? > ~/local/lib/nagios/plugins where i can see the standard plugins from omd to compare thes ones with my old nagios instance ? > replace all $USER1$ with $USER2$ if the plugin is inside the ~/local/folder what do you mean with this statment .. may you could describe a little bit more exactly .. where i have to set these variable ...in the command.cfg or could i change this in the resource.cfg ?. regards john ___ omd-users mailing list omd-users@lists.mathias-kettner.de http://lists.mathias-kettner.de/mailman/listinfo/omd-users

Hi John > > how do you merge ? with rsync ? > i would like a tool which i can choose to keep the original ones > unmodified. > Manual merge or use a diff tool, the problem is that you want some of the newer / actual settings inside your migrated site. You can also add the newer rules first to your ".mk" files and then overwrite the existing ones. > > do you have so many classical configured Nagios checks? > > jep we have many classic checks. > > Then it would be good to migrate the classical configuration first inside WATO before you start with your migration. Or other question from my side - at the moment do you define the hosts all inside WATO in your manual Nagios/Check_MK setup? > >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 > Beside the fact the we don't have many checkmk checks ( it's still for > supporting nagios.. may to replace some checks in future ) i think i can > skip these step. > > > >copy your Nagios state files to the site that the system is starting with > >the last state from the old system. > > The state file is also not critical... what it counts is the actual state > but i think i still copy these one .. it's the status.dat .. am I right ? > Yes - you have to check the naming of the files - it is sometimes different in manual Nagios installations then OMD. > > > ~/local/lib/nagios/plugins > > where i can see the standard plugins from omd to compare thes ones with my > old nagios instance ? > > OMD delivered plugins are inside ~/lib/nagios/plugins > > replace all $USER1$ with $USER2$ if the plugin is inside the ~/local/folder > > what do you mean with this statment .. may you could describe a little bit > more exactly .. where i have to set these variable ...in the command.cfg or > could i change this in the resource.cfg ?. > Inside your current resource.cfg there is the user macro defined for the standard plugin path ($USER1$) inside OMD you have two paths for plugins the standard one and the local on ($USER2$). As you have plugins in two paths you need to change the configuration to reflect this situation.
