##Requirements:

• ZENOSS 4.2+ (This will probably work with older versions)
• Apache with CGI access (other flavors would work, just not tested)
• This MUST run on the same box as the ZENOSS collector
• sudo access as root (reason: step #3, bash wrapper runs sudo -i -h zenoss)
• PHP5 (older version will probably work)
• Perl

• Time::ParseDate
• Compress::Zlib
• MIME::Base64::URLSafe
• CGI
• LWP::UserAgent

##Installing:

1. unpack files into a [webroot] of your choice (apache has been tested)

   • [webroot]/cgi-bin/.htaccess file is included to add cgi-support (AllowOverride All is needed to be set in the apache conf)

2. copy [webroot]/zenrrd.config.dist to [webroot]/zenrrd.config

   ** You must set 3 variables in the file before continuing. More details are in the config

   • renderserver_url=
   • zenoss_perf_dir=
   • zenoss_users=

3. execute [webroot]/bin/zenoss_rrd_int_csv.sh

   • you might needs to the change the first line in [webroot]/bin/get_interface_csv.py (depending on your zenoss install dir)

   I.E. #!/opt/zenoss/bin/python

   • verify it created the file "[webroot]/bin/interfaces.csv" INFO: All this does is execute a python script as the zenoss user (to access the zenoss device database) and creates the [webroot]/bin/interfaces.csv file.
   • debug: you can run '[webroot]/bin/zenoss_rrd_int_csv.sh debug' to see the output

4. ADD to crontab: (once you have verified step 3 created a [webroot]/bin/interfaces.csv)

   • this will update your interface csv

   30 * * * * root [webroot]/bin/zenoss_rrd_int_csv.sh

5. Allow graph access without the need to login to zenoss

• Visit: http://[your_zenoss_url]/zport/RenderServer/manage_access
• Allow anonymouse to 'View' -- it's close to the bottom of the page

6. Go to your website (wherever you put your [webroot])

...and explorer

##Modifying

• Feel fee to modify/update anything. If you have time to fix and add features, let me know!

• If you edit the zenrrd.js or zenrrd_zoom.js, make sure you run bin/compile_js.sh to update the minfified code or you won't see your updates. You can also of course change the includes to point at the non *.min.js files for testing.
