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 either follow IBM docu or below points:
- 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 ➡ OK ➡ OK

Allow data collection on the HMC

$ 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

Allow password less access to the HMC

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

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
```
Follow SELinux configuration in case you want to enable SELinux with our tools

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.

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)

                        (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 (/etc/cron.allow on CentOS 8) 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

Notes

OS agent upgrade

Further docu

Installation

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.

Use Grant Object Authority (GRTOBJAUT) command to grant *USE authority for APIs QPMWKCOL and QPMLPFRD:
```
GRTOBJAUT OBJ(QSYS/QPMLPFRD) OBJTYPE(*PGM) USER(LPAR2RRD) AUT(*use)
GRTOBJAUT OBJ(QSYS/QPMWKCOL) OBJTYPE(*PGM) USER(LPAR2RRD) AUT(*use)
```

Transfer LPAR2RRD.savf to IBM i system from your PC via ftp.

Test network connectivity
For example if hostname of LPAR2RRD server is LPAR2RRD-SERVER.SERVER.COM.
- ping:
```
PING RMTSYS('LPAR2RRD-SERVER.SERVER.COM') 
  Verifying connection to host system LPAR2RRD-SERVER.SERVER.COM at address 192.168.1.2.
  Connection verification statistics: 5 of 5 successful (100 %). 
```
- telnet:
```
TELNET RMTSYS('LPAR2RRD-SERVER.SERVER.COM') PORT(8162) RMTUSER(TESTSTRING) INZWAIT(15)
  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'')')
```
Recommendation: Change User profile LPAR2RRD PASSWORD to *NONE to forbid remote LPAR2RRD user access.
```
CHGUSRPRF USRPRF(LPAR2RRD) PASSWORD(*NONE)
```

Agent is licensed to free use for 1 year. You will have to re-accept license in the same way next year.
You can see expiration dates of all agents in the LPAR2RRD UI ➞ menu ➞ LPAR2RRD ➞ Data check ➞ IBM i

Start of the agent

You can start LPAR2RRD agent in two ways.

As a command RTV_SYSSTS.

CHGJOBD JOBD(LPAR2RRD/LPAR2RRD) TEXT('RTV_SYSSTS') RQSDTA(*NONE) 
RMVAJE SBSD(LPAT2RRD/LPAR2RRD) JOB(LPAR2RRD)
ADDLIBLE LPAR2RRD
GO MENU
  Option 1. Set up parameters to start client as RTV_SYSSTS (opt.10)
    Accept all default parameters for command CHGJOBD and RMVAJE.
  Option 10. RTV_SYSSTS

As an autostart job entry in LPAR2RRD subsystem.

CHGJOBD JOBD(LPAR2RRD) TEXT('STRSBS SBSD(LPAR2RRD/LPAR2RRD)') RQSDTA('RTV_SYSSTS')  
ADDAJE  SBSD(LPAR2RRD/LPAR2RRD) JOB(LPAR2RRD) JOBD(LPAR2RRD/LPAR2RRD)
ADDLIBLE LPAR2RRD
GO MENU
  Option 2. Set up parameters to start client as STRSBS LPAR2RRD (option 11)
    Accept all default parameters for command CHGJOBD and ADDAJE.
  Option 11. STRSBS LPAR2RRD

You can start LPAR2RRD agent from command line or from your CL program as a command RTV_SYSSTS or STRSBS LPAR2RRD.
Option 1 and Option 2 is used only once or when you decide to change the way the program starts.
Use F1 as a help for RTV_SYSSTS command.

Status of the agent.
```
GO MENU
  Select: Option 50
```
On the SND_SYSSTS line ➞ type 5 ➞ type 10 ➞ F10 and you have to see:

You have to see this message after 10 - 20 minutes from the agent start:
It says that connection to LPAR2RRD server has been established and some data has been already sent out.
```
IF: C_SNDSTS  - connection Established()
```
LPAR2RRD UI
You will see IBM i data in the UI after first load.sh run on the server (it usually runs once an hour).
Go to the UI, follow the server and lpar. (Ctrl-F5 is necessary to refresh the UI)

Stop of the agent

ADDLIBLE LPAR2RRD 
GO MENU
 Select: 13. END_SYSSTS ➞  Enter ➞ Enter

On the job log you will see:

WRKJOB 	
 ➞ option 10 ➞ Display job log, if active, on job queue, or pending
  F10, F18 ...
                
  IN: END_SYSSTS No active jobs in subsystem LPAR2RRD    
  Ending of subsystem LPAR2RRD in progress.              
  IN: END_SYSSTS EndSbs LPAR2RRD   *Immed                
  EN: END_SYSSTS - *ALL.                
      
GO MENU
 Select: option 50 ➞  WRKSBSJOB LPAR2RRD

See above that subsystem LPAR2RRD is not active.

if you create your user profile LPAR2RRD set JOBD parameter as a Job description which includes in INLLIBL LPAR2RRD library too (QTEMP,LPAR2RRD).
```
CRTUSRPRF USRPRF(LPAR2RRD)  ..... JOBD(LPAR2RRD/LPAR2RRD) ......
CHGJOBD JOBD(LPAR2RRD/LPAR2RRD) ....  INLLIBL(LPAR2RRD QTEMP)     ....
```

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+.
Communication problem: errors when the agent connecting the server
If you see into SND_SYSSTS eny errno > 0 message:

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.

In case of a problem check our forum or contact us via support@lpar2rrd.com

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

HMC 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.
```
$ perl /home/lpar2rrd/lpar2rrd/bin/conntest.pl 192.168.1.1 12443
  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 HM, read-only role, with password.
Use HMC local user account, not the domain one.
Allow remote access via the web:
HMC ➡ Manage User Profiles and Access ➡ select lpar2rrd ➡ modify ➡ user properties ➡ Allow remote access via the web
LPAR2RRD requires HMC LongTermMonitor enabled. It is part of Performance Monitoring in HMC Workplace.
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).
- Setup on newer HMC:
  HMC Management ➡ Console Settings ➡ Change Performance Monitoring Settings ➡ All on
  Note: in case of HMC v10 you need to go into the "user settings", and switch to the old UI: Switch to old dashboard. After switching to the old UI, you’re able to navigate to the corresponding settings.
- Setup on older HMC:
  HMC Management ➡ Operations ➡ Change Performance Monitoring Settings ➡ All On

LPAR2RRD Configuration

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

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
http://<your web server>/lpar2rrd/

Migration from older HMC CLI

If you already use LPAR2RRD with usage HMC CLI (via SSH) then you can simply migrate to REST API access.
Just follow same steps as above.
Original HMC CLI will be disabled, data will continue via REST API, no data lose

Examples

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

Type	Source	Sample rate	Data download
CMC	CMC REST API	1 minute	20 mins
HMC
	HMC REST API	1 minute	20 mins
	HMC CLI	1 minute	1 hour
OS agent
	AIX	1 minute	~20 mins

Install LPAR2RRD server

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

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 (/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 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/
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
