$(data \format\)-01.log files

Hello.
I have Nagios® Core™ Version 3.4.1 installed from debian repository. May be it's too old, but I don't want to reinstall it till I'll be sure that this is version issue.
The problem is that nagios can't find log files earlier than 3 days from now.
I mean that nagi is looking in that order:
today: /var/log/nagios3/nagios.log
yesterday: /var/log/nagios3/archives/nagios-10-29-2014-00.log
the day before yesterday: /var/log/nagios3/archives/nagios-10-28-2014-00.log
...
/var/log/nagios3/archives/nagios-10-26-2014-01.log
all previous logs are search with 01.log index. And I receive an error that this file can not be found. That's right! There is no such file over there... I have only
20K -rw-r--r-- 1 nagios adm 19K Oct 25 23:57 nagios-10-26-2014-00.log
Should I write a bash script that renames all old log files? Or may be I should install the last version? (I don't really want to do it)
I have nagios installed since 2012 and even first files has 00.log index. I don't use log reports very often, but some time ago I was able to watch all archive files for sure.
Thanks for help.

Interesting, so you are saying you cant even manually find the archived logs properly? Do you have something running on the system such as rsync, or a cron that moves .log files to a central location? Something that might explain this in that capacity?

I have only nagios logrotate configured that puts logs daily in archive folder. No problem with that.
Problem is that when I try to watch logs through web interface, it tries to find log file with this strange index. I don't have any files with ...-01.log index, in archive folder.
As an example
I want to see logs for 10-27-2014 through web interface. When I come to this date, nagi tries to find file with name nagios-10-27-2014-00.log. Here is no problem.
But when I want to see logs for 10-26-2014, web interface says that there is no nagios-10-27-2014-01.log file. And it's right! there is no such file. I have nagios-10-27-2014-00.log file.

I am going to have to look at the changelog and possibly how the code handles that portion of it. It sounds like logrotate moving them into the archive dir and not naming them in our convention is what is causing the issue though. Could you post the logrotate config you have, while I check a few things?

Oh, that didn't cross my mind to look in to changelog. Thanks for clue.
logrotate option from nagios.cfg file
Code: Select all
# LOG ROTATION METHOD
# This is the log rotation method that Nagios should use to rotate
# the main log file. Values are as follows..
# n = None - don't rotate the log
# h = Hourly rotation (top of the hour)
# d = Daily rotation (midnight every day)
# w = Weekly rotation (midnight on Saturday evening)
# m = Monthly rotation (midnight last day of month)
log_rotation_method=d
# LOG ARCHIVE PATH
# This is the directory where archived (rotated) log files should be
# placed (assuming you've chosen to do log rotation).
log_archive_path=/var/log/nagios3/archives
Thank you.

Well that looks correct, but something in your rotation configs must be appending the date as well, unless its configured to remove the file, in which case nagios will probably create a new one and break the logging that way. Also out of curiosity, is there a reason you are not using the default nagios rotation within nagios.cfg and instead are using logrotate on its own?

Are you using anything else along with nagios, that can have impact on log rotation, i.e. mk_livestatus?

Code: Select all
$ sudo dpkg -L check-mk-livestatus
dpkg-query: package 'check-mk-livestatus' is not installed
Code: Select all
ls /etc/logrotate.d/
apache2 aptitude clamav-freshclam dpkg exim4-paniclog mysql-server nginx rsyslog
apt bacula-common consolekit exim4-base fail2ban nagiosgrapher php5-fpm
I dont think that I have something else configured to rotate logs, at least I didn't configure it.
As nagios documentation says daily rotation perform at midnight.
Code: Select all
ls -lsct /var/log/nagios3/archives

Creation time is midnight. But I guess another log rotate program create daily rotation at midnight too, and this doesn't proof anything.
My first log files ever created by nagios are

With this index 00 too. I read changelog and didn't find there any necessary information.
I can only guess where is the problem. Is it in nagi web interface scripts, that tries to parse wrong files? Or in is in log rotation from the very beginning? Do you have 01-index in your file names?

None of the archived logs should include "01-index" ion the name. They should be named:

Thaks a lot. I'll try to find why nagios web interface is looking for index 01 file. If I'll succeed I'll answer here.
