Nagios Support Forum

I am trying to test upgrade from Ubuntu 20 to Ubuntu 22.

Old Machine was nagiosclt is PHP7.4
New Machine is nagiosclt22 is PHP8.1

When I manually run the command /usr/bin/php -q /usr/local/nagiosxi/cron/sysstat.php
I get the following response below, any ideas? Compatibility issue with PHP8?


PHP Fatal error: Uncaught mysqli_sql_exception: Incorrect string value: '\xE2\x94\x94\xE2\x94\x80...' for column 'value' at row 1 in /usr/local/nagiosxi/html/db/adodb/drivers/adodb-mysqli.inc.php:788

How did you transfer the nagios data to the new host?
I guess this is nagios XI?
See the backup and restore doc for info on switching to a new OS version.

I'm not sure. But maybe it can help https://ubiq.co/database-blog/how-to-fix-incorrect-string-value-in-mysql/

@gormank - Thanks, spot on.....I completely forgot that when changing the O/S you should backup/restore the database and run the repair script to update ... the combination of the two resolved all the issues and it is running as expected now.

cd /tmp/
wget https://assets.nagios.com/downloads/nag ... _repair.sh
chmod +x restore_repair.sh
./restore_repair.sh
