Installing (or Upgrading) opEvents

As of February 2016, opEvents is distributed in a self-extracting download format that simplifies the installation process quite a bit. More information on running the installer can be found HERE: The Opmantek Installer

Transfer the opEvents tarball installer onto the server in question, either by direct download from the Opmantek website (using wget as demonstrated below), or from your desktop with scp or , sftp or a similar file transfer tool.
Make a record of where you put the tarball installer (we recommend using root's home directory or /tmp are as good locations).

• Become root and unpack the tarball:Remember, you must have root access to run the installer, so either use sudo or log in as root.

• Start the interactive installer and follow its instructions. The installer now fully covers both initial installations as well as upgrades from earlier versions of opEvents.

• 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.

Initial Configuration

• If the interactive installer installed MongoDB it will also configure opEvents to connect to it. However, if you did not instruct the installer to install mongoDB, or if yoy want to point opEvents to use mongoDB on another server, you will need to adjust the MongoDB-related settings:open 

  • Open /usr/local/omk/conf/opCommon.nmis in an editor, go to the database section and change the server, username and password to reflect your MongoDB installation.

  • The

  result

  • example below is from a default installation with a local MongoDB installed by the opEvents installer. Your entries should look similar to the following (but there might be extra settings related to other products):

    Code Block
    'database' => {

  • 'db_admin_port' => '28017', 'db_connection_timeout' => 20000, 'db_name' => 'nmis', 'db_

• For opEvents versions before 1.2.2 Only 

/usr/local/omk/bin/opeventsd.pl act=setup
# you can also get an overview of opeventsd's capabilities by running opeventsd.pl --help

• After completing your configuration changes you'll need to restart both the opEvents daemon (opeventsd) as well as the Opmantek daemon (omkd).
  Simply run the following commands as root:

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