Hi,

1)First and foremost: backup all the volumes on your server

2)Once you have completed your backup you can delete what you are comfortable with in /store/backups/nagiosxi. I advise
keeping the last 3 backups at a minimum. They should be saved in the *.tar.gz format to save space. That number that is in the
file or directory name is the Unix timestamp. You can decode it using a site like https://www.unixtimestamp.com/index.php

3)Everything in /tmp can be deleted, but you should only do it when Nagios xi isn't running.

Once you do the above 3 items let's see how much room you have. Go to "/" and execute:

Code: Select all

du -h -d 1

It'll come back with something like this:

Code: Select all

[root@gs-cent8-23-82 /]# du -h -d 1
143M    ./boot
0       ./dev
du: cannot access './proc/113573/task/113573/fd/4': No such file or directory
du: cannot access './proc/113573/task/113573/fdinfo/4': No such file or directory
du: cannot access './proc/113573/fd/3': No such file or directory
du: cannot access './proc/113573/fdinfo/3': No such file or directory
0       ./proc
41M     ./run
0       ./sys
25M     ./etc
70M     ./root
609M    ./var
3.2G    ./usr
12K     ./home
0       ./media
0       ./mnt
0       ./opt
0       ./srv
457M    ./tmp
0       ./store
4.5G    .

From there we can continue to drill down to find things to delete.

Thanks

Thanks GSmith

upon your point 2) , i have deleted RED COLOR files in this my first thread and now i think will give me relax till end of this year (hope so) but one question, why NAGIOSxi creating this Files (Directory?) when there is already file created .tar.gz ?

I just kept three , but why this getting created by NAGIOSxi , what is purpose or its DUPLICATE process doing this mischief ?

drwxr-xr-x 7 nagios users 4096 Apr 25 05:10 nagiosxi.1619316061

can you please let me know in general this green file is more than enough if something went wrong with nagiosxi and have to restore with any good file, if YES then same above question why above RED color DIRECTORY getting created and consuming to much space / time and process and .....

Thank for good advice to SHUT NAGIOSxi then remove ./tmp Files.

The directories in red have different time stamps, and are thus different backup operations.

Perhaps there is a bug that causes the backup process to not clean up after itself, but did you have some backups fail recently, possibly due to lack of disk space on the backup volume?

Dear dchurch

how to know backup done successfully or not? i dont have any idea to know it. plz guide.

if you see RED and GREEN , both on same date/time (nearly)... may be there is some DUPLICATE process but i found its very very random. Please make sure there is no bug in your latest release, if there is please remove.

my one of question not answered, can you please let me know if below pattern file is enough to take backup and require to restore in case of any disaster, then safe to delete any other file(s).

nagiosxi.xxxxxxxxxx.tar.gz

regards

You can test your backup archive's integrity by running "tar tf nagiosxi.1619313661.tar.gz" - if it exits with an error, then the tarball is incomplete.

As far as the bug goes, I can submit a bug report on your behalf if you'd like. Please keep in mind that the decision to implement the enhancement is at the discretion of our development team.

And yes, that pattern will work for your purposes, at least until Nov 20, 2289 when you'll have to add another "x"
