Configure FusionCompute in LPAR2RRD

  • LPAR2RRD UI ➡ Settings icon ➡ Huawei FusionCompute ➡ New
    FusionCompute configuration

    If you see "Please change the password to ensure account security" in the connection test, you need to log in to the FusionCompute Web Client and change the password.
    FusionCompute configuration

  • Make sure cron job for FusionCompute is in place (upgrade script might do it for you automatically)
    Skip this step if you install the Virtual Appliance - it is already taken care of.
    $ crontab -l | grep "load_fusioncompute.sh"
    $
    
    Add following lines to crontab if necessary
    $ crontab -e
    
    # Huawei FusionCompute support
    0,20,40 * * * *  /home/lpar2rrd/lpar2rrd/load_fusioncompute.sh > /home/lpar2rrd/lpar2rrd/load_fusioncompute.out 2>&1
    
  • Wait 30 minutes and then go to the web UI: http://<your web server>/lpar2rrd/

Install LPAR2RRD server (all under lpar2rrd user)

  • Download the latest LPAR2RRD server
    Upgrade your already running LPAR2RRD instance.

  • Install it:
    # su - lpar2rrd
    $ tar xvf lpar2rrd-7.XX.tar
    $ cd lpar2rrd-7.XX
    $ ./install.sh
    $ cd /home/lpar2rrd/lpar2rrd
    
  • Make sure all Perl modules are in place
    cd /home/lpar2rrd/lpar2rrd
    . etc/lpar2rrd.cfg; $PERL bin/perl_modules_check.pl
    
    If there is missing "LWP::Protocol::https" then check this docu to fix it

  • Enable Apache authorisation
    umask 022
    cd /home/lpar2rrd/lpar2rrd
    cp html/.htaccess www
    cp html/.htaccess lpar2rrd-cgi
    
  • Schedule to run it from lpar2rrd crontab (it might already exist there)
    $ crontab -l | grep load.sh
    $
    
    Add if it does not exist as above
    $ crontab -e
    
    # LPAR2RRD UI
    0,30 * * * * /home/lpar2rrd/lpar2rrd/load.sh > /home/lpar2rrd/lpar2rrd/load.out 2>&1 
    
    Assure there is just one such entry in crontab.

  • You might need to add lpar2rrd user into /etc/cron.allow (Linux) or /var/adm/cron/cron.allow (AIX) if 'crontab -e' command fails
    Allow it for lpar2rrd user as root user.
    # echo "lpar2rrd" >> /etc/cron.allow
    
  • Make sure you have a cron job for Azure is in place (upgrade script might do it automatically) Skip it on the Virtual Appliance, it is already there.
    $ crontab -l | grep "load_fusioncompute.sh"
    $
    
    Add it if it does not exist like above
    $ crontab -e
    
    # Azure support
    0,20,40 * * * *  /home/lpar2rrd/lpar2rrd/load_fusioncompute.sh > /home/lpar2rrd/lpar2rrd/load_fusioncompute.out 2>&1 
    
  • Initial start from cmd line:
    $ cd /home/lpar2rrd/lpar2rrd
    $ ./load.sh
    
  • Go to the web UI: http://<your web server>/lpar2rrd/
    Use Ctrl-F5 to refresh the web browser cache.

Troubleshooting

  • If you have any problems with the UI then check:
    (note that the path to Apache logs might be different, search apache logs in /var)
    tail /var/log/httpd/error_log             # Apache error log
    tail /var/log/httpd/access_log            # Apache access log
    tail /var/tmp/lpar2rrd-realt-error.log    # STOR2RRD CGI-BIN log
    tail /var/tmp/systemd-private*/tmp/lpar2rrd-realt-error.log # STOR2RRD CGI-BIN log when Linux has enabled private temp
    
  • Test of CGI-BIN setup
    umask 022
    cd /home/lpar2rrd/lpar2rrd/
    cp bin/test-healthcheck-cgi.sh lpar2rrd-cgi/
    
    go to the web browser: http://<your web server>/lpar2rrd/test.html
    You should see your Apache, LPAR2RRD, and Operating System variables, if not, then check Apache logs for connected errors
