In the Nagios XI interface, the Status Information shown for a service stops at 256 characters (anything after is cut off). When you look at the service in Nagios Core you can see the entire Status Information.
In Nagios XI, that data is stored in a database as opposed to Core. When XI stores it in the database, the database has a limit as to how much data can be stored.
The database can be updated so that it can store more information.
Open an SSH session to your XI server and execute the following commands:
echo "use nagios;alter table nagios_servicestatus modify output varchar(65535) not null;alter table nagios_servicestatus modify long_output TEXT not null;alter table nagios_servicestatus modify perfdata TEXT not null;" | mysql -pnagiosxi
echo "use nagios;alter table nagios_hoststatus modify output varchar(65535) not null;alter table nagios_hoststatus modify long_output TEXT not null;alter table nagios_hoststatus modify perfdata TEXT not null;" | mysql -pnagiosxi
echo "use nagios;alter table nagios_servicechecks modify output varchar(65535) not null;alter table nagios_servicechecks modify long_output TEXT not null;alter table nagios_servicechecks modify perfdata TEXT not null;" | mysql -pnagiosxi
echo "use nagios;alter table nagios_hostchecks modify output varchar(65535) not null;alter table nagios_hostchecks modify long_output TEXT not null;alter table nagios_hostchecks modify perfdata TEXT not null;" | mysql -pnagiosxi
Note:
These are long commands
The commands end with -pnagiosxi where nagiosxi is the default password. If you have changed your database password you'll need to change the command to reflect this.
