Linux RedHat, CentOS

    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
    
    # yum install perl rrdtool rrdtool-perl httpd
    # yum install epel-release ed bc sharutils
    # yum install perl-TimeDate perl-XML-Simple perl-XML-SAX perl-XML-LibXML perl-Env perl-CGI perl-Data-Dumper perl-LWP-Protocol-https perl-PDF-API2 perl-libwww-perl libxml2 perl-Time-HiRes
    
    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-7-9.noarch.rpm

Linux Debian, Ubuntu

    # umask 0022
    # apt-get install apache2 perl rrdtool ed bc
    # apt-get install librrdp-perl libxml-sax-perl libxml-simple-perl libtimedate-perl libenv-sanctify-perl libcgi-pm-perl libdata-dumper-simple-perl libpdf-api2-perl libxml2-utils
    # apt-get install liblwp-protocol-https-perl=6.04-2 libcrypt-ssleay-perl libio-socket-ssl-perl libmozilla-ldap-perl libxml-parser-perl
    
    Note that liblwp-protocol-https-perl must be exactly at version 6.04-2!
    Other available versions like 6.07-2, 6.06-2 or 6.02-1 have a bug which prevents working it with HMC v9+.
    Only Debian based Linux distributions are affected.
    If you do not have access to the internet then get it from liblwp-protocol-https-perl 6.04-2
    Prevent updating it in operating system
    # apt-mark hold liblwp-protocol-https-perl
      liblwp-protocol-https-perl set on hold.
    

AIX

    Install RRDTool 1.4.8 with all prerequisites for AIX
    If you use yum on AIX then do not use rrdtool-1.7.0-4, it has a bug, use rrdtool-1.7.0-3 instead

Solaris

    # /opt/csw/bin/pkgutil -y -i pm_xml_simple pm_libxml_perl pm_xml_sax rrdtool
    
You have 2 options how to connect the HMC.
  • HMC REST API: it brings you physical adapter stats, enhanced configuration in compare to CLI access,
    it uses read-only user on the HMC with a password authentification
  • HMC CLI: it uses ssh-key based authorisation on HMC, read-only account

HMC CLI

  • Allow access from the LPAR2RRD host to all HMCs on port 22 TCP
    You might either verify it manually from command line or run "test" in the UI after HMC addition.
    $ perl /home/lpar2rrd/lpar2rrd/bin/conntest.pl 192.168.1.1 22
      Connection to "192.168.1.1" on port "22" is ok
    
  • Assure you can connect to the HMC via ssh. If not then:
    • Enable remote cmd execution:
      HMC UI (classic) ➡ HMC management ➡ Remote Command Execution ➡ Enable
    • Assure that HMC firewall allows incoming ssh conections :
      HMC UI (classic) ➡ HMC management ➡ Change net settings ➡ LAN adapters ➡ Select open interface ➡ Firewall ➡ Select SSH ➡ Allow incoming

Allow data collection on the HMC

    Allow utilization data collection (either via the HMC UI or globally via following cmd as hscroot)
    $ ssh hmc1 -l hscroot 
    hscroot@hmc1:~> chlparutil -r config -s 60
    hscroot@hmc1:~> lslparutil -r config  -F name,sample_rate
    PWR6A-9117-MMA-SN103AXXX,60
    PWR6B-9117-MMA-SN103BXXX,60
    
    Use padmin account for IVM, or sysadmin for SDMC/FLEX
    Repeat that for all your HMCs/IVMs/SDMCs.

Allow password less access to the HMC

    Create ssh keys (type enter when you are prompted for passphrase) under lpar2rrd user on LPAR2RRD server
    $ who am I
      lpar2rrd    pts/0       Jan 10 10:13     (192.168.1.240)

Connectivity test

  • test the connection between the LPAR2RRD hosted server and HMC
    (should not request password any more) as lpar2rrd user:
    $ ssh -l lpar2rrd hmc1
      The authenticity of host 'hmc1 (9.138.236.97)' can′t be established.
      RSA key fingerprint is 97:e1:a5:c2:58:3c:c6:0c:d1:6f:4d:6e:62:9c:68:4b.
      Are you sure you want to continue connecting (yes/no)? yes
    lpar2rrd@hmc1:~> 
    
  • if you use a commercial SSH distribution (like F-Secure ssh) which supports only SSH2 format (above example was for OpenSSH format), then you need to convert public keys onto OpenSSH format before uploading the keys into HMC. Convert SSH2 to OpenSSH format and after that use it in mkauthkeys:
    $ ssh-keygen -i -f your-ssh2.pub > your-openssh.pub
    
  • Configure HMC from LPAR2RRD UI (v6.00+)

  • Allow "real-time" refresh on demand, WEB user (apache, nobody) needs to have access to SSH keys
    • find out WEB user
      $ ps -ef|egrep "apache|httpd"|grep -v grep|awk '{print $1}'|grep -v "root"|head -1 
        nobody
      
    • under root user copy SSH keys and change ownership to the WEB user
      # cp /home/lpar2rrd/.ssh/id_rsa /home/lpar2rrd/.ssh/realt_rsa  
      # chown nobody /home/lpar2rrd/.ssh/realt_rsa  
      # chmod 600 /home/lpar2rrd/.ssh/realt_rsa
      
  • Assure you have enough of disk space on the fs where is LPAR2RRD installed
    Roughly you might count 5MB/lpar (10MB/lpar in dual HMC setup) == 1GB/100lpars (without the OS agent)
    $ df -g /home # AIX
    $ df -h /home # linux
    
  • Schedule alerting
    $ crontab -e  
    
    0,10,20,30,40,50 * * * * /home/lpar2rrd/lpar2rrd/load_alert.sh > /home/lpar2rrd/lpar2rrd/load_alert.out 2>&1
    
  • Schedule job for getting network IVE (HEA) statistics if you use it in your IBM Power servers
    $ crontab -e
    
    0,5,10,15,20,25,30,35,40,45,50,55 * * * * /home/lpar2rrd/lpar2rrd/load_hea.sh > /home/lpar2rrd/lpar2rrd/load_hea.out 2>&1

Apache download

  • AIX
    Apache 2.4.18 from IBM AIX Toolbox for Linux Applications
    Apache 2.4.4 from M. Perlz's archive.

  • 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
    
    If you have firewall enabled then enable LPAR2RRD communication by:
    # 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.... )

  • 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 either "(13)Permission denied:" or "AH00132: file permissions deny server access" 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
      

OS agent is add-on feature for monitoring from operating system level.
It is monitoring CPU, memory utilization, paging, LAN and SAN traffic on all adapters.
It requires the OS agent deployment to every monitored LPAR.
The agent is written in Perl and calls basic OS commands to obtain required statistics like vmstat, lparstat and svmon.

OS agent architecture

Additional information about the OS agent: NMON support via the OS agent
HMC monitoring via the OS agent
IBM i (AS/400) OS agent

Prerequisites

  • Perl on each LPAR (each OS already contains it, no special modules necessary)
  • Opened TCP communication between each LPAR and LPAR2RRD server on port 8162.
    Connections are initiated from LPARs.
  • Additional disk space on LPAR2RRD server (about 40MB per each monitored LPAR)
  • Create preferable dedicated user lpar2rrd on each host with minimum rights
    # useradd -s /usr/bin/ksh  -c "LPAR2RRD agent user" -m lpar2rrd
    
  • In case of VIO server do not use padmin account and mkuser cmd, that would not work!
    Create the account under root in the same way as on usual AIX (like above useradd).

OS agent installation (client)

  • Get the latest OS agent from download page

  • AIX & Linux installation under root
    # rpm -Uvh lpar2rrd-agent-6.00-0.ppc.rpm
    # rpm -qa|grep lpar2rrd-agent
      lpar2rrd-agent-6.00-0
    
    AIX 7.1+ note: you might need to specify option "--ignoreos" if you get an error:
    "package lpar2rrd-agent-5.00-0 is for a different operating system"
    # rpm -Uvh --ignoreos lpar2rrd-agent-6.00-0.ppc.rpm
    
  • Linux Debian
    # apt-get install lpar2rrd-agent_6.00-0_all.deb
      lpar2rrd-agent-6.00-0
    
  • Oracle Solaris installation under root:
    # gunzip lpar2rrd-agent-5.00-0.solaris-i86pc.tar.gz
    # tar xf lpar2rrd-agent-5.00-0.solaris-i86pc.tar
    # pkgadd -d .
      The following packages are available:
      1  lpar2rrd-agent     LPAR2RRD OS agent 5.00
                            (i86pc) 5.00
     ...
    
    Oracle Solaris upgrade under root:
    # pkgrm lpar2rrd-agent
    # pkgadd -d .
    
  • Schedule its run every minute from the crontab on every LPAR.
    This line must be placed into lpar2rrd crontab:
    # su - lpar2rrd
    $ crontab -e 
    * * * * * /usr/bin/perl /opt/lpar2rrd-agent/lpar2rrd-agent.pl <LPAR2RRD-SERVER.your-domain.com> > /var/tmp/lpar2rrd-agent.out 2>&1
    
    Replace <LPAR2RRD-SERVER> by hostname of your LPAR2RRD server.
    Use preferably FDQN in LPAR2RRD hostname, hostname only might have a problem with resolving.

  • You might need to add lpar2rrd user into /var/adm/cron/cron.allow under root user if above "crontab -e" fails.
    # echo "lpar2rrd" >> /var/adm/cron/cron.allow
    

LPAR2RRD server (daemon)

  • Edit etc/lpar2rrd.cfg and set following (if it is not already set):
    $ vi /home/lpar2rrd/lpar2rrd/etc/lpar2rrd.cfg
    
    LPAR2RRD_AGENT_DAEMON=1
    
  • The daemon is started when load.sh starts
    $ ./load.sh
      Starting LPAR2RRD daemon on port:8162
      ...
    
  • Assure it is running and listening on port 8162:
    $ ps -ef|grep lpar2rrd-daemon
      lpar2rrd 10617010 1 0 Mar 16 - 0:00 /usr/bin/perl -w /home/lpar2rrd/lpar2rrd/bin/lpar2rrd-daemon.pl
    $ netstat -an| grep 8162
      tcp4  0  0  *.8162   *.*   LISTEN
    
  • OS agent data graphs will appear in the UI, use Ctrl-F5 to refresh your web browser

Troubleshooting

  • Client (agent) side:
    • Test if communication through the LAN is allowed.
      $ telnet  <LPAR2RRD-SERVER> 8162
        Connected to 192.168.1.1   .
        Escape character is '^]'.
      
      This is ok, exit either Ctrl-C or ^].

    • Check following agent files:
      data store: /var/tmp/lpar2rrd-agent-*.txt
      error log: /var/tmp/lpar2rrd-agent-*.err
      output log: /var/tmp/lpar2rrd-agent.out

    • run the agent from cmd line:
      $ /usr/bin/perl /opt/lpar2rrd-agent/lpar2rrd-agent.pl -d <LPAR2RRD-SERVER>
        ...
        Agent send     : yes : forced by -d 
        Agent send slp: sending wait: 4
        OS/HMC agent working for server: <LPAR2RRD-SERVER>
        store file for sending is /var/tmp/lpar2rrd-agent-<LPAR2RRD-SERVER>-lpar2rrd.txt
      
      It means that data has been sent to the server, all is fine
      Here is example when the agent is not able to sent data :
      $ /usr/bin/perl /opt/lpar2rrd-agent/lpar2rrd-agent.pl -d <LPAR2RRD-SERVER>
        ...
        Agent send     : yes : forced by -d 
        Agent send slp: sending wait: 1
        OS/HMC agent working for server: <LPAR2RRD-SERVER>
        store file for sending is /var/tmp/lpar2rrd-agent-<LPAR2RRD-SERVER>-lpar2rrd.txt
        Agent timed out after : 50 seconds /opt/lpar2rrd-agent/lpar2rrd-agent.pl:265
      
      It means that the agent could not contact the server.
      Check communication, port, above telnet example, DNS resolution of the server etc.

  • Server side:
    • test if the daemon on LPAR2RRD server is running, and checking the logs
      $ ps -ef|grep lpar2rrd-daemon
        lpar2rrd 10617010 1 0 Mar 16 - 0:00 /usr/bin/perl -w /home/lpar2rrd/lpar2rrd/bin/lpar2rrd-daemon.pl
      $ cd /home/lpar2rrd/lpar2rrd
      $ tail logs/error.log-daemon
      $ tail logs/daemon.out
        new server has been found and registered: Linux (lpar=linuxhost01)
        mkdir : /lpar2rrd/data/Linux/no_hmc/linuxhost01/
      
      It means that new OS agent has been registered from linuxhost01 (Linux stand-alone example)

    • Test if OS agent data is being stored on the LPAR2RRD server and have actual timestamp:
      $ cd /home/lpar2rrd/lpar2rrd
      $ ls -l data/<server name>/*/<lpar name>/*mmm
        -rw-r--r-- 2 lpar2rrd staff  7193736 Mar 17 16:16 data/<server name>/<hmc name>/<lpar name>/cpu.mmm
        -rw-r--r-- 2 lpar2rrd staff  7193736 Mar 17 16:16 data/<server name>/<hmc name>/<lpar name>/lan-en1.mmm
        -rw-r--r-- 2 lpar2rrd staff 10790264 Mar 17 16:16 data/<server name>/<hmc name>/<lpar name>/mem.mmm

        -rw-r--r-- 2 lpar2rrd staff  7193736 Mar 17 16:16 data/<server name>/<hmc name>/<lpar name>/san-vscsi0.mmm
        -rw-r--r-- 2 lpar2rrd staff  3597208 Mar 17 16:16 data/<server name>/<hmc name>/<lpar name>/san_resp-vscsi0.mmm
      $ find data -name mem.mmm -exec ls -l {} \;
        ...

LPAR2RRD IBM i agent

  • Download the latest OS agent for IBM i (R6.1.0+).
    After unzipping you get LPAR2RRD.savf in save file format.

  • Open TCP communication on your network between each IBM i LPAR with the OS agent installed and LPAR2RRD server on port 8162. Connections are initiated from the agent side (IBM i).

  • Create User Profile LPAR2RRD This user profile will be owner of all restored objects in library LPAR2RRD and this user profile is the name of the user profile for the agent being submitted.
    Parameters of CRTUSRPRF command depend on AS400 security policy you have in place.

  • Create save file destination:
    CRTSAVF FILE(QGPL/LPAR2RRD) 
    
  • Execute that only if you installing Enterprise Edition of LPAR2RRD IBM i OS agent.
    It contains ASP latency monitoring.

        Connecting to remote host 192.168.1.2 using port 8162
      
      If you get after 15 seconds "No response from remote host system within open time-out." then it is wrong!.
      Either LPAR2RRD server daemon is not running or TCP connection is filtered on the network by a firewall.
      If connection hanging (it times out in 10 mins) then it is ok, you can interrupt it by:
         SysRq ➡ Enter ➡ 2. End previous request

  • Configure LPAR2RRD server host
    Change Monitor Server Name or IP addr (IPADR) to your running LPAR2RRD server
    This step must be done, because default server IP address for sending data is LOOPBACK.
    • Using hostname:
      CHGCMDDFT CMD(LPAR2RRD/RTV_SYSSTS) NEWDFT('IPADR(LPAR2RRD-SERVER.SERVER.COM)')
      
    • Using IP address:
      CHGCMDDFT CMD(LPAR2RRD/RTV_SYSSTS) NEWDFT('IPADR(''192.168.1.2'')')

Notes

  • LPAR2RRD agent uses dlpar_get_info API - service program QPMLPMGT in QSYS.
    When user profile LPAR2RRD under which LPAR2RRD agent being submitted is not authorized to this service program, obtain authority to this service program e.g. by command:
    GRTOBJAUT OBJ(QSYS/QPMLPMGT) OBJTYPE(*SRVPGM) USER(LPAR2RRD) AUT(*USE)
    
    Be careful if you upgrade your i5/OS. Service program QPMLPMGT is into QSYS library.

Troubleshooting

  • Communication problem: repeated connections with failures.
    This is a bug in v1.1.0 agent version which might very rare occure, upgrade to v1.1.1+.
    AS400 agent bug

  • Communication problem: errors when the agent connecting the server
    If you see into SND_SYSSTS eny errno > 0 message: AS400 screenshot 4

    There is a communication error.
    It might have 2 reasons:
    • IP address or port is wrong. (check above how to change it)
    • IP connection between LPAR2RRD server and IBM i is not allowed on port 8162.
    Execute ping and telnet tests mentioned above to verify network accesibility

    Stop the agent and correct IP address/port or firewall setup. Start it up as soon as it is fixed.

Feel free to comment our implementation or discuss issues on our web forum
You have 2 options how to connect the HMC.
  • HMC REST API: it brings you physical adapter stats, enhanced configuration in compare to CLI access,
    it uses read-only user on the HMC with a password authentification
  • HMC CLI: it uses ssh-key based authorisation on HMC, read-only account

HMC REST API

It supports HMC v8+, use HMC CLI (ssh) in case of older HMCs
You can use HMC CLI on older HMCs and HMC REST API on newer HMCs in single LPAR2RRD instance

Configuration

  • Allow access from the LPAR2RRD host to all HMCs on port 12443 TCP
    You might either verify it manually from command line or run "test" in the UI after HMC addition.

      Connection to "192.168.1.1" on port "12443" is ok
    
  • AIX: These 2 packages are mandatory on AIX, assure they are installed (on LPAR2RRD server only):
    # rpm -qa | egrep -i "Crypt-SSLeay|Net_SSLeay"
      perl-Crypt-SSLeay-0.57-2
      perl-Net_SSLeay.pm-1.55-3
    
    Download it from sourceforge.net or lpar2rrd.com
    # rpm -Uvh perl-Crypt-SSLeay-0.57-2.aix6.1.ppc.rpm
    
    Download it from sourceforge.net or lpar2rrd.com
    # rpm -Uvh --nodeps --replacefiles perl-Net_SSLeay.pm-1.55-3.aix6.1.ppc.rpm
    
  • Create lpar2rrd user on each HMC with read-only role, with password.

  • Allow remote access via the web:
    HMC ➡ Manage User Profiles and Access ➡ select lpar2rrd ➡ modify ➡ user properties ➡ Allow remote access via the web
    IBMPower REST API remote access


  • LPAR2RRD requires HMC LongTermMonitor enabled. It is part of Performance Monitoring in HMC Workplace.
    HMC Management ➡ Operations ➡ Change Performance Monitoring Settings ➡ All On
    This performance monitoring can store up to 366 days of data. LPAR2RRD uses performance data only 30 minutes old so you can set the minimum number of days to store performance data (1 day).

  • Configure HMC access in the LPAR2RRD UI, start at the settings button on the top right.

  • If you use IVM (Integrated Virtualization Manager) as data source then they must excluded as they have no REST API
    It must be configured for HMC CLI access (lslparutil).
    Edit etc/lpar2rrd.cfg and place all IVMs into new entry:
    IVM_LIST="ivm1 ivm2 ..."
    
  • Assure you have a cron job for HMC REST API in place (upgrade script might do it automatically)
    Skip it on the Virtual Appliance, it is already there.
    # su - lpar2rrd
    $ crontab -l | egrep "load_hmc_rest_api.sh"
    $
    
    Add if they do not exist like above
    $ crontab -e
    
    # IBM Power Systems - REST API
    0,20,40 * * * * /home/lpar2rrd/lpar2rrd/load_hmc_rest_api.sh > /home/lpar2rrd/lpar2rrd/load_hmc_rest_api.out 2>&1
    
  • Wait about 30 minutes, then refresh the web browser cache by Ctrl-F5

Migration from older HMC CLI

If you already use LPAR2RRD with usage CLI (lslparutil via SSH) then you can simply migrate to REST API access.
Just follow same steps as above.
Once you connect the first HMC then all communications will be switched to REST API.
Original HMC CLI (lslparutil) will be disabled.
Connect all your HMCs then to do not lose data.

Examples

Check our live demo site where all IBM Power servers data came through REST API.

Issues

Some older IBM Power Systems models (firmwares) might report warnings when is enabled "Data Collection" on the HMC.
It is not connected to LPAR2RRD!
Both issues we have seen were confirmed by IBM support as informative only, no real problem.

    To avoid that you can disable "Data Collection" on the HMC for that particular server.
    This server can be further disabled even in LPAR2RRD REST API processing and it will continue via HMC CLI (lslparutil)
    Let us know, UI form for that is not implemented yet, however manually it is possible ...

Install LPAR2RRD server

  • 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
    
  • 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 job for HMC REST API in place (upgrade script might do it automatically)
    Skip it on the Virtual Appliance, it is already there.
    $ crontab -l | grep "load_hmc_rest_api.sh"
    $
    
    Add it if it does not exist like above
    $ crontab -e
    
    # HMC REST API support
    0,20,40 * * * *  /home/lpar2rrd/lpar2rrd/load_hmc_rest_api.sh > /home/lpar2rrd/lpar2rrd/load_hmc_rest_api.out 2>&1 
    
  • Initial start from cmd line:
    $ cd /home/lpar2rrd/lpar2rrd
    $ ./load.sh
    
  • Go to the web UI: http://<your web server>/lpar2rrd/
