Can you run the following as root on the Nagios server and post the output?

Code: Select all

echo 'desc nagios_logentries;' |mysql -u root -pnagiosxi nagios -t
I am thinking you have a check that is returning a lot of data and overflowing the MYSQL table.
Do you know if you have a check defined like that?

All of the info you have posted is after the failure happened, we would need to see the log entry when the error first happens and some entries before that.
Can you check through all of the messages files in the /var/log folder to find the first error for the nagios_logentries table and post it here?

Code: Select all

[root@NAGIOS ~]# echo 'desc nagios_logentries;' |mysql -u root -pnagiosxi nagios -t
ERROR 144 (HY000) at line 1: Table './nagios/nagios_logentries' is marked as crashed and last (automatic?) repair failed
I looked through logs for a good while, unfortunately I don't really know what I am looking for. I don't have any checks like you're describing. Most of checks are very basic, there are hundreds of them, but they are basic.

I can replicate this issue.. If you have certain log files you would like me to watch, I can fix the database using the script, then watch it closely and wait for it to break again?

Go ahead and repair the database and then run this command again and post the output.

Code: Select all

echo 'desc nagios_logentries;' |mysql -u root -pnagiosxi nagios -t
What you have to look for is when you start to see this error message.

Code: Select all

./nagios/nagios_logentries' is marked as crashed and last (automatic?) repair failed
or this error message

Code: Select all

NAGIOS ndo2db: Error: mysql_query() failed for 'INSERT INTO nagios_logentries SET instance_id='1'
in the /var/log/messages file.

Hopefully some lines before those errors, you will see something that could be causing the issue and you can post it here so we can view it.

I will keep a close eye on it and keep you updated. Thanks for the help

Thanks for the output.
The logentry_data field is fairly small ant I thing when a plugin runs and returns more data then the size of that field, it corrupts the table.
Lets increase the size of that field by running the following command as root on the XI server.

Code: Select all

echo "use nagios;alter table nagios_logentries modify logentry_data varchar(65535) not null;" | mysql -pnagiosxi
Hopefully this will solve the recurring corrupted table issue.
