Bulk Installation of Linux Server Monitoring agent using Chef

Unattended installation can be performed by following the below steps:

The Chef cookbook is available in the following links

Chef community - http://community.opscode.com/cookbooks/site24x7

Github - https://github.com/site24x7/chef-site24x7

Download Site24x7 cookbook into your chef-repo/cookbooks.site24x7 directory. The name of the cookbook directory should be site24x7
```
https://github.com/site24x7/chef-site24x7 
```
Set your DEVICE KEY. Edit site24x7/attributes/default.rb and replace YOUR_USER_DEVICE_KEY with your unique Site24x7 DEVICE Key.
```
* 'default[:Site24x7][:DEVICEkey]' = "YOUR_USER_DEVICE_KEY"
```
Device key can be obtained from Admin > Developer > Device Key.

Set proxy attribute if necessary

* 'default[:Site24x7][:proxy]' = "user:password@proxyhost:proxyport"

Upload the cookbook to your chef server or hosted chef
```
* 'knife cookbook upload site24x7'
```
Include recipe[site24x7] in the run_list for all of your servers
```
* 'knife node run_list add NODES 'recipe[site24x7]''
```
Run the chef-client on your nodes in either of the two ways described below,
```
* 'sudo chef-client -i 3600 -s 600' or a batch job.
```

This will ensure automatic installation of the agent in your server.
