Introduction

Windows Azure Monitor includes utilities to monitor different aspects of Windows
Azure. These utilities are designed to be used with Nagios and Zabbix, but could
also be used in other creative ways.

Installation

Two ways to install:

1. Download and extract the source package. Run 'python setup.py install' See 
   http://docs.python.org/2.7/install/index.html for additional information

2. Install using pip, 'pip install azuremonitor' Some distributions call pip
   pip-python.

Dependencies

* Python 2.6 or 2.7
* azure - Window Azure sdk for Python
* argparse - For Python 2.6
* OpenSSL - pyOpenSSL
* pyodbc - Connect to SQL Azure
* FreeTDS - Used by ODBC to connect to SQL Azure

Setup

Nagios

1. Create symlinks from your Nagios plugin directory to the Azure monitor utilities.
   Example::

    ln -s /usr/bin/check_azure_compute.py /usr/lib64/nagios/plugins
    ln -s /usr/bin/check_azure_ad.py /usr/lib64/nagios/plugins
    ln -s /usr/bin/check_azure_sql.py /usr/lib64/nagios/plugins
    ln -s /usr/bin/check_azure_storage.py /usr/lib64/nagios/plugins
    ln -s /usr/bin/check_azure_paas.py /usr/lib64/nagios/plugins

2. Download your .publishsettings file for your Azure account. Something like:
   https://windows.azure.com/download/publishprofile.aspx

3. Move your .publishsetttings file to a safe place and protect it. Example::

    mv azure.publishsettings /etc/nagios/private
    chmod 640 /etc/nagios/private/azure.publishsettings
    chown root:nagios /etc/nagios/private/azure.publishsettings

   Here only root and the nagios group, which nagios runs under, is allowed to
   read the file

4. Optionally set a variable in your resource.cfg (usually /etc/nagios/private/resource.cfg)
   To point to your publishsettings file

5. Setup a command in a config file as usual for nagios::

    define command{
        command_name    check_azure_compute
        command_line    $USER1$/check_azure_compute.py $HOSTADDRESS$ -p $PSFILE$
    }
    define command{
        command_name    check_azure_sql
        command_line    $USER1$/check_azure_sql.py $HOSTADDRESS$ $ARG1$
    }

    define command{
        command_name    check_azure_ad
        command_line    $USER1$/check_azure_ad.py $HOSTADDRESS$ $ARG1$
    }

    define command{
        command_name    check_azure_paas
        command_line    $USER1$/check_azure_paas.py $HOSTADDRESS$ $ARG1$
    }

    define command{
        command_name    check_azure_storage
        command_line    $USER1$/check_azure_storage.py $HOSTADDRESS$ $ARG1$
    }

6. In the service file setup appropriate parameters. Examples::

      check_command       check_azure_sql!-d azuredb -u username -p pwd  -k dbsize -vv!
      check_command       check_azure_ad!-c clientid -s secret -k listusers -vv!
      check_command       check_azure_paas!-p psfile -s storageact -k availmemory -w 3000: -c 2000: -vv!
      check_command       check_azure_storage!-p psfile --table --tx  -k percentsuccess -w 99: -c 95:!

Zabbix

1. Use these utilities as an external check: https://www.zabbix.com/documentation/1.8/manual/config/items#external_checks

2. You may need to increase the timeout for external check in yor zabbix_server.conf::

       Timeout=10

3. Also in zabbix_server.conf, uncomment the ExternalScripts location, if commented::

    ExternalScripts=/etc/zabbix/externalscripts

4. Link the utilities to that location. Example::

    ln -s /usr/bin/check_azure_compute.py /etc/zabbix/externalscripts

5. Download your .publishsettings file for your Azure account. Something like:
   https://windows.azure.com/download/publishprofile.aspx

6. Move you .publishsetttings file to a safe place and protect it. Example::

    mv azure.publishsettings /etc/zabbix
    chmod 640 /etc/zabbix/azure.publishsettings
    chown root:zabbix /etc/zabbix/azure.publishsettings

   Here only root and the zabbix group, which zabbix runs under, is allowed to
   read the file

7. Use the zabbix interface to setup the external check. Example::

       Item
       External check
       Key: check_azure_compute.py[-p /etc/zabbix/azure.publishsettings]
       Type:    Character

8. Use the zabbix interface to setup the trigger. Example::

       Trigger
       Expression:
       {<host/template>:check_azure_compute.py[-p /etc/zabbix/azure.publishsettings].str(All cool)}=0
