Register an application

The Office365 Management API use Azure AD to authenticate against Office365. To access the Office365 Management API, you need to register your application in Azure AD. Application is here used by Microsoft as a conceptual term, referring not only to the application software, but also to the Azure AD registration and role in authentication/authorization "conversations" at runtime.

FAQ

How can I test the Plugin in the CLI and what do the main parameters stand for ?

Once the Centreon Plugin installed, you can test it directly in the CLI of the Centreon poller by logging with the centreon-engine user:

/usr/lib/centreon/plugins//centreon_office365_exchange_api.pl \
  --plugin=cloud::microsoft::office365::exchange::plugin \
  --mode=email-activity \
  --tenant='abcd1234-5678-90ab-cd12-34567890abcd' \
  --client-id='9876dcba-5432-10dc-ba98-76543210dcba' \
  --client-secret='8/RON4vUGhAcg6DRmSxc4AwgxSRoNfKg4d8xNizIMnwg='

Expected output:

OK: Active mailboxes on 2019-03-10 : 141/1532 (9.20%) - Total (active mailboxes)
Send Count: 9478, Receive Count: 62197, Read Count: 24401 |
'active_mailboxes'=141mailboxes;;;0;1532
'total_send_count'=9478;;;0;
'total_receive_count'=62197;;;0;
'total_read_count'=24401;;;0;

The available thresholds as well as all of the options that can be used with this Plugin can be displayed by adding the --help parameter to the command:

/usr/lib/centreon/plugins//centreon_office365_exchange_api.pl \
  --plugin=cloud::microsoft::office365::exchange::plugin \
  --mode=email-activity \
  --custommode='graphapi'\
  --help

You can display all of the modes that come with the Plugin with the command below:

/usr/lib/centreon/plugins//centreon_office365_exchange_api.pl \
  --plugin=cloud::microsoft::office365::exchange::plugin \
  --list-mode

Why do I get the following error:

UNKNOWN: 500 Can't connect to ...:443

This error message means that the Centreon Plugin couldn't successfully connect to the Office365 Management API. Check that no third party device (such as a firewall) is blocking the request. A proxy connection may also be necessary to connect to the API. This can be done by using the --proxyurl option in the command.

UNKNOWN: 501 Protocol scheme 'connect' is not supported |

When using a proxy to connect to the Office365 Management API, this error message means that the Centreon Plugin library does not support the proxy connection protocol.

In order to prevent this issue, use the curl HTTP backend by adding the following option to the command: --http-backend='curl'.
