...

• available here).
• All licenses are added/updated at https://<hostname>/omk/opLicense .

Preparation

• If you do not yet have a working installation of NMIS in your server, please follow the procedure in the NMIS 8 Installation Guide.
• Download opCharts from the Opmantek website.

Installation

opCharts is distributed in a self-extracting download format that simplifies the installation process. More information on running the installer can be found on The Opmantek Installer page.

Transfer the opCharts installer file onto the server in question, either by direct download from the Opmantek website, or from your desktop with scp or sftp or a similar file transfer tool.

• Start the interactive installer and follow its instructions:

  Code Block
  sudo sh ./opCharts-Linux-x86_64-3.0.7.run ... ++++++++++++++++++++++++++++++++++++++++++++++++++++++ opCharts (3.0.7) Installation script ++++++++++++++++++++++++++++++++++++++++++++++++++++++ ... This installer will install opCharts into /usr/local/omk. To select a different installation location please rerun the installer with the -t option.

  
  

• The installer will interactively guide you through the steps of installing opCharts. Please make sure to read the on-screen prompts carefully.
• When the installer finishes, opCharts is installed into /usr/local/omk, and the default configuration files are in /usr/local/omk/conf, ready for your initial adjustments.
• A detailed log of the installation process is saved as /usr/local/omk/install.log, and subsequent upgrades or installations of other Opmantek products will add to that log file.

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. 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 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 /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.

Where to go from 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.
