Installation Steps

Transfer the opCharts tarball 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.
Make a record of where you put the tarball (root's home directory or /tmp are good locations).

  • Become root and unpack the tarball:

  • Start the interactive installer and follow its instructions:

  • 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 config 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 logfile.
  • For detailed information about the interactive installer please check the Opmantek Installer page.

Initial Configuration

  • You will need to adjust the NMIS-related settings:
    open 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):

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

  • 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 the existing users.dat file in omk/conf/ will be used, if that is not found the default users.dat file will be copied to omk/conf/. 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.
