Description: Network Resource Grapher

ui_msg "\n#### To complete the NRG installation ####

1) Make an /nrg symlink in your Apache document root pointing to the ../nrg/web NRG data directory:

sudo ln -s ${prefix}/var/${name}/web /my-Apache-document-root/nrg

2) Modify your httpd.conf file for NRG graph pages:

Uncomment lines: AddHandler cgi-script .cgi
LoadModule expires_module libexec/httpd/mod_expires.so
AddModule mod_expires.c

Add directives:
Options ExecCGI



ExpiresActive On
ExpiresDefault M5


Change the Apache user and group to the NRG user and group so Apache will
have permissions to create graphs when you click an RRD file link.

User
Group

3) Change the web root variables at the top of files Makefile and Site.mconf
in directory ${prefix}/var/${name} to your Apache document root location.

4) Make NRG files and data owned by the user you'll use to run NRG

su (must be root for this operation)
find ${prefix}/var/nrg -print | xargs chown :


#### To use NRG ####

1) Set meta-configuration definitions in the Site.mconf file for each
resource you want to graph by following the example meta-configuration
definitions in ${prefix}/share/doc/nrg/examples.

2) Have NRG generate rrd files and html graph pages (and modify them after
Site.mconf changes):

cd ${prefix}/var/${name}
make rediscover
make notify

3) Schedule the script ${prefix}/var/${name}/run-nrg to run via cron every five
minutes to poll your data sources and update the rrd files.

Be sure to read the documentation in ${prefix}/share/doc/${name}/html for
creating custom graphs or for more information.\n"
