Hello,

Mariadb.log is throwing loads of the following message:

00205 15:06:39 [Warning] Unsafe statement written to the binary log using statement format since BINLOG_FORMAT = STATEMENT. INSERT...

Hello @exp-user1,

Thanks for posting the log, let's run the repair script to fix any corrupted tables. Log into the shell as root and run the following script:

Code: Select all

/usr/local/nagiosxi/scripts/repair_databases.sh

If the issue still persists, send us your system profile for us to review and further troubleshoot. Thanks.

To send us your system profile.
Login to the Nagios XI GUI using a web browser
Click the "Admin" > "System Profile" Menu
Click the "Download Profile" button
Save the profile.zip file and share this in a private message and then reply to this post to bring it up in the queue.

Hello,

I did DB repair but the problem persists.
Could you specify certain things that can help you in your investigation other than system profile?

Thanks

Hello @exp-user-1,

It's a warning message, are you noticing any other issues (i.e performance loss)? Do you have database replication configured on this system?

Let us know. It would be helpful to review the my.cnf file from the server.

Hello,

we do have DB replication, here is my.cnf

[mysqld]
query_cache_size=16M
query_cache_limit=4M
tmp_table_size=64M
max_heap_table_size=64M
key_buffer_size=32M
table_open_cache=32
innodb_file_per_table=1

# include all files from the config directory

!includedir /etc/my.cnf.d

Another thing, logentries is NULL. DB repair fixes this but the next day it gets NULL again.

echo "SELECT table_name AS 'Table', round(((data_length + index_length) / 1024 / 1024), 2) 'Size in MB' FROM information_schema.TABLES WHERE table_schema IN ('nagios', 'nagiosql', 'nagiosxi');" | mysql -uroot -pnagiosxi --table |grep logentries
| nagios_logentries | NULL |

Any help?

Hello @exp-user1,

Can you disable the replication and test to confirm whether or not the issue with logentries table is resolved? Let me know.
