Skip Prerequisites, Web and LPAR2RRD tabs in case of configuring
Virtual Appliance,
Docker or a
Container
Follow installation procedure for your operating system platform
Implementation is agentless, all data is gathered from Oracle VM Manager.
Supported is OVM 3.3 and 3.4.
Oracle VM Manager host connectivity
Users access
You have to use the
admin user, because Oracle VM does not support role based access
You can create a different user if you wish (eg. 'lpar2rrd'), but it must have admin rights anyway.
Attach Oracle VM Manager hosts
-
LPAR2RRD UI ➡ Settings icon ➡ Oracle VM ➡ New :
Make sure that connection test passes without errors or warnings.
- Make sure cron jobs for Oracle VM Manager are 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_oraclevm.sh"
$
Add following lines to crontab if necessary
$ crontab -e
# OracleVM support
0,20,40 * * * * /home/lpar2rrd/lpar2rrd/load_oraclevm.sh > /home/lpar2rrd/lpar2rrd/load_oraclevm.out 2>&1
- Wait 30 minutes and then go to the web UI: http://<your web server>/lpar2rrd/
Use Ctrl-F5 to refresh the web browser cache.
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-6.XX.tar
$ cd lpar2rrd-6.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
su - lpar2rrd
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 /var/adm/cron/cron.allow if crontab command fails
Allow it for lpar2rrd user as root user.
# echo "lpar2rrd" >> /var/adm/cron/cron.allow
- Assure you have a cron jobs for OracleVM in place (upgrade script might do it automatically)
Skip it on the Virtual Appliance, it is already there.
$ crontab -l | grep "load_oraclevm.sh"
$
Add it if it does not exist like above
$ crontab -e
# OracleVM support
0,20,40 * * * * /home/lpar2rrd/lpar2rrd/load_oraclevm.sh > /home/lpar2rrd/lpar2rrd/load_oraclevm.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
