## Modified attributes

Introduction

Several attributes of hosts, services, and contacts can be changed during runtime, e.g. when disabling notifications through the webinterface, thus overriding the local configuration default. The core will always use the modified attributes in the first place.

If "retain_state_information" is enabled (this is the default) these changes will be saved across restarts. If you choose to disable this setting the changes will only last until the next restart.

Apart from changing them automatically via several commands in the classic UI you can alter the values using external commands.

List of external commands to modify attributes (for details see the list of external commands)

- change host attributes: `CHANGE_HOST_MODATTR;`<host_name>;<value>

- change service attributes: `CHANGE_SVC_MODATTR;`<host_name>;<service_description>;<value>

- change contact attributes: `CHANGE_CONTACT_MODATTR;`<contact_name>;<value>

- change contact attributes: `CHANGE_CONTACT_MODHATTR;`<contact_name>;<value>

- change contact attributes: `CHANGE_CONTACT_MODSATTR;`<contact_name>;<value>

The value is a logical OR of the different values from the table at the end of this section. "Logical OR" means that you have to add the values and use the result.

Example

The following lines show a general example how to submit external commands to the command file.

     #!/bin/sh
     # Adjust variables to fit your environment as necessary.

     now=`date +%s`
     commandfile='/usr/local/icinga/var/rw/icinga.cmd'

     /bin/printf "[%lu] CHANGE_HOST_MODATTR;Host1;11\n" $now > $commandfile

The above command will modify several attributes on "Host1":

    enable notifications      1
    enable active checks      2
    enable the eventhandler   8
                             --
                             11
