# useradd -c "LPAR2RRD user" -m lpar2rrd # chmod 755 /home/lpar2rrd
- Increase limits for user lpar2rrd and the WEB server user (under root)

RHEL 8: enable the codeready-builder-for-rhel-8-*-rpms repository
# ARCH=$( /bin/arch ) # subscription-manager repos --enable "codeready-builder-for-rhel-8-${ARCH}-rpms" -
CentOS 8: enable the PowerTools repository
# yum config-manager --set-enabled PowerTools or # dnf config-manager --set-enabled powertools
You can also just open /etc/yum.repos.d/CentOS-Linux-PowerTools.repo with a text editor and set enabled= to 1 instead of 0

Follow this for installing perl-PDF-API2 on RHEL/CentOS 8

Note that rrdtool-perl and epel-release (this is necessary only for PDF reporting) might not be in your RedHat base repository especially for RHEL 6.x and olders.
Install CentOS package instead rrdtool-perl-1.4.8-9.el7.x86_64.rpm and epel-release-7-11.noarch.rpm

Apache start / restart
-
Command depends on Apache version, one of these should work:
# apachectl restart # /opt/freeware/apache/sbin/apachectl restart # /etc/init.d/httpd restart # service apache2 restart
# firewall-cmd --add-service=http --permanent # firewall-cmd --add-service=https --permanent # firewall-cmd --add-port=8162/tcp --permanent # firewall-cmd --reload
Test web pages
-
Point your web browser to
http://<your lpar2rrd host>/lpar2rrd/ as soon as you configure LPAR2RRD
Do not forget to ensure that Apache starts after the OS reboot (there must be a starting script in /etc/rc.... )

Configure httpd.conf, it might be in different locations (depends of distribution)- /etc/httpd/httpd.conf
- /etc/httpd/conf/httpd.conf
- /etc/opt/freeware/apache/httpd.conf (AIX)
- /opt/freeware/etc/httpd/httpd.conf (AIX)
- /opt/freeware/etc/httpd/conf/httpd.conf (AIX)
- /etc/apache2/apache2.conf
- Verify alias_module and cgi_module is loaded (uncommented it, the path can be different)
LoadModule alias_module /opt/freeware/lib/httpd/modules/mod_alias.so LoadModule cgi_module /opt/freeware/lib/httpd/modules/mod_cgi.so
- cgi_module could depend on mpm_prefork_module like here.
Allow it as well (uncomment it) and disable mpm_worker_module, mpm_event_moduleLoadModule mpm_prefork_module /opt/freeware/lib/httpd/modules/mod_mpm_prefork.so # LoadModule mpm_worker_module /opt/freeware/lib/httpd/modules/mod_mpm_worker.so # LoadModule mpm_event_module modules/mod_mpm_event.so <IfModule mpm_prefork_module> LoadModule cgi_module /opt/freeware/lib/httpd/modules/mod_cgi.so </IfModule> - Append this at the end of httpd.conf

SELinux changes
You need to disable the SELinux service protection to be able to utilize basic web services.
You must do it in case you get "(13)Permission denied:" in Apache error_log.
You have 2 options:
- Disable SELinux only for Apache
Step 1. Query for the Boolean value you need to change: # getsebool -a | grep httpd_dis httpd_disable_trans --> off Step 2. Disable the SELinux protection: # setsebool -P httpd_disable_trans=1 Step 3. Verify that the Boolean has changed: # getsebool -a | grep httpd_dis httpd_disable_trans --> on
- Globally disable SELinux
# setenforce Permissive # vi /etc/sysconfig/selinux SELINUX=disabled
- Disable SELinux only for Apache
LPAR2RRD is able to monitor stand-alone MS Windows servers and MS Hyper-V performance metrics.
Implementation is done through single Windows OS agent running on any Windows host in the Windows domain.
This OS agent gets all required configuration from the AD and performance data of monitored hosts through WMI.
It passes such data to LPAR2RRD server where data is saved and presented.
LPAR2RRD Windows OS agent works everywhere where is available PowerShell 3 and higher
It does not directly depends on Windows version, if you are able to upgrade PowerShell to 3.0+ on older machines then it will work.
Installation summary
- Allow TCP connection initiated from Windows LPAR2RRD Hyper-V agent server to LPAR2RRD server on port 8162
- PowerShell version 3 and higher only is supported on Windows hosts
User creation
- Create LPAR2RRD user in the AD with membership in these groups:
- Event Log Readers
- Hyper-V Administrators
- Performance Log Users
- Performance Monitor Users
- Set rights in GPO and AD using this manual
- Give local admin rights to the LPAR2RRD user on the Win server where LPAR2RRD Hyper-V agent will be running.
Add him into Domain Users group.
- Assign read-only rights for monitored Hyper-V clusters to LPAR2RRD user
OS agent installation
Unzip LPAR2RRD-Win-agent-1.3.3.zip |
| Unblock these files by right clicking them and checking "Unblock" Setup.vbs, Configuration.vbs, LPAR2RRD-agent.ps1 LPAR2RRD-agent-Configuration.ps1, LPAR2RRD-agent-Installer.ps1  |
Run Setup.vbs |
Select installation directory  |
Put hostname of the LPAR2RRD server  |
Test connection to the LPAR2RRD server  |
Put user which will run LPAR2RRD OS aget on this machine  |
Select monitored mode (agent v1.3.3+)  |
-
You can also use manuall OS agent installation
In case of a cluster: add there cluster name and names of all nodes as well like: cluster1,node1,node2,cluster2,node...
- Wait about 30 minutes, then Ctrl-F5 in your LPAR2RRD UI and you should see Hyper-V folder in the main menu
Monitored modes
-
The agent can run in these modes:
- leave it in default mode and monitor just the server where it is installed
- monitor all visible servers from AD
- monitor only specific servers (recommended), added into cfg file
for monitoring of cluster - add its name to servers/nodes too like: cluster1,node1,node2,cluster2,node...
Mode configuration is selected during installation or run whenever Configuration.vbs in the agent install dir.
Win OS agent release notes
Skip it in case of configuring Virtual Appliance
Install LPAR2RRD server
-
Definitelly use the latest available version (6.10+ at least)
- Install it:
# su - lpar2rrd $ tar xvf lpar2rrd-7.XX.tar $ cd lpar2rrd-7.XX $ ./install.sh $ cd /home/lpar2rrd/lpar2rrd
- Schedule to run it from lpar2rrd crontab (it might already exist there)
Add if it does not exist as above$ crontab -l | grep load.sh $
$ 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 (/etc/cron.allow on CentOS 8) 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 Hyper-V in place (upgrade script might do it automatically)
Skip it on the Virtual Appliance, it is already there.Add it if it does not exist like above$ crontab -l | grep "load_hyperv.sh" $
$ crontab -e # MS Hyper-V support 0,20,40 * * * * /home/lpar2rrd/lpar2rrd/load_hyperv.sh > /home/lpar2rrd/lpar2rrd/load_hyperv.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
S2D prerequisites
- WinServer 2019
- Performance history enabled (enabled by default) docs.microsoft.com/en-us/windows-server/storage/storage-spaces/performance-history
Just install the latest Windows OS agent and upgrade to LPART2RRD 7.30+ to get S2D statistics.
