Installation

Synology storage installation

In case of usage of Virtual Appliance
  • Use local account lpar2rrd for hosting of STOR2RRD on the virtual appliance
  • Use /home/stor2rrd/stor2rrd as the product home
The product obtains all data from storage SNMP interface.

Install Prerequisites (skip that in case of Virtual Appliance)

  • AIX
    Download Net-SNMP packages and install them.
    Do not use the latest packages on AIX, it does not work, use net-snmp-5.6.2.1-1!
    # umask 0022
    # rpm -Uvh net-snmp-5.6.2.1-1 net-snmp-utils-5.6.2.1-1 net-snmp-perl-5.6.2.1-1
    
    Make sure
    • you use PERL=/opt/freeware/bin/perl in etc/stor2rrd.cfg
    • PERL5LIB in etc/stor2rrd.cfg contains /opt/freeware/lib/perl5/vendor_perl/5.8.8/ppc-thread-multi path

  • Linux
    # umask 0022
    # yum install net-snmp
    # yum install net-snmp-utils
    # yum install net-snmp-perl
    
    Note you might need to allow optional repositories on RHEL to yum can find it
    # subscription-manager repos --list
    ...
    # subscription-manager repos --enable rhel-7-server-optional-rpms
    
    Use rhel-7-for-power-le-optional-rpms for Linux on Power etc ...

  • Linux Debian/Ubuntu
    % umask 0022
    % apt-get install snmp libsnmp-perl snmp-mibs-downloader
    
    Assure that this line is commented out in /etc/snmp/snmp.conf
    #mibs :
    
    If apt-get does not find snmp-mibs-downloader package then enable contrib and non-free repositories.

Allow network access

  • Allow access from the STOR2RRD host to the storage (EVS IP) on port 161 UDP .
    Test if port is open:
    $ perl /home/stor2rrd/stor2rrd/bin/conntest_udp.pl 192.168.1.1 161
      Connection to "192.168.1.1" on port "161" is ok
    

Storage SNMP configuration

    Open storage UI ➡Terminal & SNMP:
    Storage management

STOR2RRD storage configuration

    Add storage into configuration from the UI:
    Settings icon ➡ Storage ➡ New ➡ Vendor:device ➡ Synology
    Storage management

  • Assure you have enough of disk space on the filesystem where is STOR2RRD installed
    Roughly you might count 2 - 30 GB per a storage (it depends on number of volumes, 30GB for 5000 volumes)
    $ df -g /home   # AIX
    $ df -h /home   # Linux
    
  • Schedule to run storage agent from stor2rrd crontab (lpar2rrd on Virtual Appliance, it might already exist there)
    $ crontab -l | grep load_synologyperf.sh
    $
    
    Add if it does not exist as above
    $ crontab -e
    
    # Synology
    0,5,10,15,20,25,30,35,40,45,50,55 * * * * /home/stor2rrd/stor2rrd/load_synologyperf.sh > /home/stor2rrd/stor2rrd/load_synologyperf.out 2>&1
    
    Assure there is already an entry with the UI creation running once an hour in crontab
    $ crontab -e
    
    # STOR2RRD UI (just ONE entry of load.sh must be there)
    5 * * * * /home/stor2rrd/stor2rrd/load.sh > /home/stor2rrd/stor2rrd/load.out 2>&1
    
  • Let run the storage agent for 15 - 20 minutes to get data, then:
    $ cd /home/stor2rrd/stor2rrd
    $ ./load.sh
    
  • Go to the web UI: http://<your web server>/stor2rrd/
