Initial Configuration

• You will need to adjust the NMIS-related settings:
  open /usr/local/conf/opCommon.nmis in an editor, go to the nmis section and change the nmis_dir to reflect your NMIS installation. 
  The result should look similar to the following (but there might be extra settings related to other products):

  Code Block
  'nmis' => { 'nmis_dir' => '/usr/local/nmis8',  'nmisConf' => 'Config', '<nmis_logs>' => '/usr/local/nmis8/logs', 'nmis_host_base' => 'http://localhost', 'nmis_cgi_url_base' => '/cgi-nmis8', 'prefer_local_nmis' => 'false' },

  
  

• After completing your configuration changes you'll need to restart the opCharts daemon.
  Simply run Run the following commands as root: 

  Code Block
  # don't forget to become root, using sudo sh or su service opchartsd restart service omkd restart # to verify the status of the daemons: service opchartsd status service omkd status

  
  

• Authentication
  The installer will backup /usr/local/omk/conf/users.dat and then create a symlink to users.dat in your NMIS directory if it was found during installation.  If
  If the NMIS users.dat file could not be found during installation the existing users.dat file in /usr/local/omk/conf/ will be used, if that .
  If /usr/local/omk/conf/users.dat is not found the default users.dat file will be copied to /usr/local/omk/conf/ from /usr/local/omk/install/.
  Default credentials can be found here.

First you should test opCharts: open up a web browser, and point it to "http://<yourserverip>/omk/opCharts"; , you will have to enter your license first, then you will see opCharts' main dashboard. See the authentication bullet point above for user/password info.
