Restore NagVis maps from the backups...

So, It finally happened that someone broke a NagVis map while trying to update it. It got really messed up.
In the file /usr/local/nagiosxi/scripts/backup_xi.sh the NagVis tool was missing for a while, but is now included.
It is even included in /usr/local/nagiosxi/scripts/restore_xi.sh too. It was missing from those in earlier versions.
Since it is now there for us to run manually, I thought... well...
So I decided to look in the file created by "Admin" -> "Scheduled Backups" and pull out a copy of the file from before it degraded. It turns out that of all the files in that tar.gz file there was no NagVis. So, I tried to look at the php code and add it. Nope. Not gonna happen... That code is part of the special stuff the end users are not able to change. (SourceGuardian)
So, can someone please look in /usr/local/nagiosxi/html/includes/components/scheduledbackups and make sure that NagVis gets included when scheduled backups run?
NagVis is part of the Nagios XI install... It should be included in the Nagios XI backups.
If it is already there, then tell me I'm crazy... If not, Please add it.
I did get the file restored from an OS backup but I should not have had to take that route.
Thanks

H-m-m, I grepped for "nagvis" the "backup_xi.sh" & "restore_xi.sh" script, and it seems NagVis is being backup up...
Code: Select all
[root@localhost scripts]# pwd
/usr/local/nagiosxi/scripts
[root@localhost scripts]# grep -i nagvis backup_xi.sh
echo "Backing up Nagvis..."
tar czfp $mydir/nagvis.tar.gz /usr/local/nagvis
[root@localhost scripts]# grep -i nagvis restore_xi.sh
# Nagvis
if [ -f $backupdir/nagvis.tar.gz ]; then
echo "Restoring Nagvis backups..."
rm -rf /usr/local/nagvis
cd $rootdir && tar xzfps $backupdir/nagvis.tar.gz
chown -R apache.apache /usr/local/nagvis

When you run those files manually, sure, it is being backed up. I said that in my post.
But, what about the items I asked about? The scheduled backups. On the Admin tab, Scheduled backups, FTP, SSH, or Local.
I was very specific I thought.

The Scheduled Backups component is using the same script to do the backups (backup_xi.sh). We don't have a "separate" script for scheduled backups...

BTW, one way to verify what I said, is to run a tail on the "cmdsubsys.log" while scheduled backup is running.

When I was unable to read the php I thought there was something special happening in the component that was a secret. So I did not chase it any further. I Appreciate the response. I'll go thru the tar file again and make sure not to miss the information this time. In case it happens again.
Thank you for clearing that up for me. My apologies...

No problem, Steve. I am glad I was able to help! Is it ok if we lock this topic or you want us to keep it open for the time being?
