Nagios XI - Status Information Cut Off At 256 Characters

Problem Description

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.

 

Explanation

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.

 

Resolving The Problem

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 varchar(65535) not null;alter table nagios_servicestatus modify perfdata varchar(65535) not null;" | mysql -pnagiosxi

echo "use nagios;alter table nagios_hoststatus modify output varchar(65535) not null;alter table nagios_hoststatus modify long_output varchar(65535) not null;alter table nagios_hoststatus modify perfdata varchar(65535) not null;" | mysql -pnagiosxi

echo "use nagios;alter table nagios_servicechecks modify output varchar(65535) not null;alter table nagios_servicechecks modify long_output varchar(65535) not null;alter table nagios_servicechecks modify perfdata varchar(65535) not null;" | mysql -pnagiosxi

echo "use nagios;alter table nagios_hostchecks modify output varchar(65535) not null;alter table nagios_hostchecks modify long_output varchar(65535) not null;alter table nagios_hostchecks modify perfdata varchar(65535) 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.

  • If our have offloaded MySQL to another server, these commands need to be executed on the offloaded server.
