Skip it in case of configuring Virtual Appliance

Apache download

  • Linux CentOS, RedHat 
    # yum install httpd
  • Linux Debian, Ubuntu 
    # apt-get install httpd

Apache configuration

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

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.... )

Apache configuration per platform and version

  • Linux CentOS, RedHat


    Append at the end of /etc/httpd/conf/httpd.conf following 
    # vi /etc/httpd/conf/httpd.conf

AddHandler cgi-script .sh
# DocumentRoot  "/home/lpar2rrd/lpar2rrd/www/"

</Directory>

  • Linux Debian, Ubuntu : Apache2 (2.4+)


    Enable CGI-BIN 
    # a2enmod cgi
    Append this at the end of /etc/apache2/apache2.conf 
    # vi /etc/apache2/apache2.conf

  • Apache 2.4+ generally


    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)

    1. 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
    2. cgi_module could depend on mpm_prefork_module like here.
      Allow it as well (uncomment it) and disable mpm_worker_module, mpm_event_module 
      LoadModule 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>
    3. Append this at the end of httpd.conf 
      AddHandler cgi-script .sh
Alias /lpar2rrd  "/home/lpar2rrd/lpar2rrd/www/"
<Directory "/home/lpar2rrd/lpar2rrd/www/">
    Options Indexes FollowSymLinks 
    Require all granted
</Directory>
# CGI-BIN
ScriptAlias /lpar2rrd-cgi/ "/home/lpar2rrd/lpar2rrd/lpar2rrd-cgi/"
<Directory "/home/lpar2rrd/lpar2rrd/lpar2rrd-cgi">
    AllowOverride None
    SetHandler cgi-script
    Options ExecCGI FollowSymLinks
    Require all granted
</Directory>
      Sometimes appears necessary to remove "Require all granted" lines in both directives.

  • Apache 1.3 - 2.3


    Configure httpd.conf, it might be in different locations (depends of distribution)
    • /etc/httpd/httpd.conf
    • /etc/httpd/conf/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

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.

Hyper-V schema

Installation summary

  1. Allow TCP connection initiated from Windows LPAR2RRD Hyper-V agent server to LPAR2RRD server on port 8162
  2. Make sure your LPAR2RRD daemon is running on LPAR2RRD server

User creation

  1. Create LPAR2RRD user in the AD with membership in these groups:
    • Event Log Readers
    • Hyper-V Administrators
    • Performance Log Users
    • Performance Monitor Users
    This must be done for all Hyper-V nodes and MS Windows servers that are supposed to be monitored (this can be set globally in AD).
    Use this manual for user creation and assigning rights in the AD.

  2. 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.

  3. Assign read-only rights for monitored Hyper-V clusters to LPAR2RRD user
    Hyper-V cluster rights 1
    Hyper-V cluster rights 2

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
    Hyper-V OS agent install

    Run Setup.vbs

    Select installation directory
    Hyper-V OS agent install

    Put hostname of the LPAR2RRD server
    Hyper-V OS agent install

    Test connection to the LPAR2RRD server
    Hyper-V OS agent install

    Put user which will run LPAR2RRD OS aget on this machine
    Hyper-V OS agent install

    Select monitored mode (agent v1.3.3+)
    Hyper-V OS agent install
  • Wait about 30 minutes, then Ctrl-F5 in your LPAR2RRD UI and you should see Hyper-V folder in the main menu

Monitored modes (agent version 1.3.2+)

    Older agent versions trying to get and monitor all servers in AD which are visible for the user.
    Since v1.3.2 there is a change and the agent monitors just the server where it is installed.

    Version 1.3.2 brings configuration file where is possible to define what will be monitored.
    There are these options:
    1. leave it in default mode and monitor just the server where it is installed
    2. monitor all visible servers from AD
    3. monitor only specific servers, manually added into cfg file

    Mode configuration is selected during installation or run whenever Configuration.vbs in the agent install directory.
    Mode configuration in agent v1.3.2 is possible only manually by editing agent_config.txt in the agent install directory.


Skip it in case of configuring Virtual Appliance

Install LPAR2RRD server

  • Definitelly use 6.02-19 version which fixes a few issues of 6.02.
    Install or upgrade to that version before you start.
  • Install it: 
    # su - lpar2rrd
$ tar xvf lpar2rrd-6.XX.tar
$ cd lpar2rrd-6.XX
$ ./install.sh
$ cd /home/lpar2rrd/lpar2rrd
  • 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 * * * * /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 Hyper-V in place (upgrade script might do it automatically)
    Skip it on the Virtual Appliance, it is already there. 
    $ crontab -l | grep "load_hyperv.sh"
$
    Add it if it does not exist like above 
    $ 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>/stor2rrd/
