Nagios Support Forum

Hi
we have nagios XI 5.6.14 on oel 6.10. we want to migrate centos 7.8 then nagios xi 5.7.4.
we are following "Backing Up And Restoring Your Nagios XI System". we have installed new centos 7.8 and installed nagios xi 5.6.14 on it..

we have backed up our oel system successfully using backup_xi.sh script

restore part:
/usr/local/nagiosxi/scripts/restore_xi.sh /store/backups/nagiosxi/16043001044.tar.gz
it warned us about migration from el6 to el7. that is OK (according to doc)
but also it said:

restoring nagios core
tar: usr/local/nagios: cannot open: file exists
tar: exiting with failure status due to previous errors
tar: usr/local/nagios/libexec/*.*: not found in archive
tar: exiting with failure status due to previous errors
restoring nagios xi
....

after restore finishes, nagios service did not start. it says "can not open main configuration file nagios.cfg for reading"

moreover we are using an internal network which do not access internet.

we needed to have offline restore_repair package. is that possible?..or what are the requirements for this file to run successfully?
i have changed the main script so that it can run offline. but in the running part it searched for gcc and some perl packages.. i need to have all prerequisite packages..

TIA

Are you sure you're backup is good? Can you manually extract it? Send us the output of these commands:
Yes, you'll need to run the restore_repair script after restoring (it needs to be successful restoring first).

Also try doing it this way instead to see if it helps (you must run it as root/sudo):
Send us the full output from all commands so we can see everything that is occurring on the restore.

Thanks for assistance..

Yes I think there is a problem with nagios.tar.gz. there is no /data/nagios directory..
how can we solve it?

Moreover i need to have restore_repair script's all prerequisites. we are running nagios in an isolated network..

It's likely because the backup is not following the symlink to your customized installation.

You'll need to modify your backup script to do it:
Change this:
To this:
NOTE: Before restoring you'll need to make sure the symlink is in place and the data directory exists (for example, if it was a fresh install of XI):

Hi

Thank you for your support. Now we are in el7...

but i also want to summarize what happened during restore_repair.sh process as we are running in an isolated environment
1- restore_repair.sh must be revized. i have read the script, manually downloaded tarball, untarred it and changed script according to this.
2- i have encountered many problems . mostly they are required packages and utils. i have installed the following
yum install patch libmcrypt libmcrypt-devel mysql-devel gcc perl-ExtUtils-MakeMaker

after this, script has run successfully..
as a minor problem, after restore, i encountered host-perfdata and service-perfdata file can not be opened. i have deleted the old ones and nagios created new ones..

Do you have the logs from the restore repair script so we can see what actually occurred? We would need the logs to see where it was failing in order to submit it to development for revising.

Hi

we have lost performance graphs. my rrds files are not updated after migration.

as a solution:
i have restarted npcd, nagios
i have restarted performance grapher
i have deleted host-perfdata and service-perfdata files and they are recreated by nagios..
npcd.log and perfdata.log styas in the migration date. i.e not updated

but no one worked!

Moreover;
we have lost host&service critical durations. for example before migration we had a 200 days critical host. but now GUI shows only 2 days of critical state. how can we bring those real critical durations..

Hi

now i have noticed that i do not have rrdcached service according to this doc:

https://assets.nagios.com/downloads/nag ... ios-XI.pdf

do i need to follow that guide? we have migrated from oel6 to centos7. our host runs in an internal LAN

Yes, follow that RRDCacheD guide to set it up.

Once you're done, wait 15 minutes and then see if they are showing up. If they are not, PM me a FRESH copy of your profile from the new system so I can see the latest configs/logs.

i have sent PM
waiting for your reply..
