Installation Steps

  • Download opTrend from the Opmantek website.
    Copy the opTrend tarball to the server in question, using scp or sftp or similar. Make a record of where you put the tarball (likely root's home directory).

  • Become root and unpack the tarball:

    Code Block
    # as root
cd /usr/local
# if the tarball was saved in a different location, adjust the ~ in the following command 
tar xzf ~/opTrend-Linux-x86_64-1.0.0.tgz
cd /usr/local/omk 
cp install/opCommon.nmis conf/
cp -r install/trend conf
cp install/users.dat conf/
  • opTrend is now unpacked into /usr/local/omk, and the default configuration files are in /usr/local/omk/conf, ready for your initial config adjustments.

  • Integrate opTrend with the web server
    become root and run the following commands:

    Code Block
    # as root
# non-debian:
cp /usr/local/omk/conf/04omk-proxy.conf /etc/httpd/conf.d/
apachectl restart
# debian/ubuntu:
cp /usr/local/omk/conf/04omk-proxy.conf /etc/apache2/conf.d/
/etc/init.d/apache2 restart

    Note: If this step is not taken, then the opTrend web GUI will only be available on port 8042 and you'll need to adjust your web browser accordingly.

  • Adjust NMIS Access list to include opTrend 

    Code Block
    cd /usr/local/omk/
perl ./install/optrend_setup.pl setup=all

  • Make the opTrend service daemons start automatically with the system
    become root, then run the  following commands:

    Code Block
    # as root
cd /usr/local/omk/install
cp omkd.init.d /etc/init.d/omkd
# non-debian:
chkconfig omkd on
# debian/ubuntu:
update-rc.d omkd defaults

  • Start the opTrend service daemons
    become root, then run the following commands:

    Code Block
    service omkd start

  • Setup the cron jobs to run data collections, create a file /etc/cron.d/optrend

    Code Block
    # opTrend "collect"
*/5 * * * * root sleep 60;/usr/local/omk/bin/optrend.exe act=collect;
0 0 * * 0 root /usr/local/omk/bin/optrend.exe act=update
