Source of performance data are not storage devices themself but REST API of one of these:
  • Dell Storage Enterprise Manager
  • Dell Storage Manager Data Collector
Connection directly to the storage will not work, use one of above options.

User rights options

  • Create user xormon under admin role or use already existing admin account.
  • Admin rights give you visibility of the whole storage include items not being under any folder and system subsystems like:
    • Node (controller): CPU, IO, data, response time
    • Port: IO, data, response time

  • Create user xormon under Reporter role and assign him rights to all or specific:
    • volume folders
    • server folders
    • disk folders
    In this case will be reported utilization only for assigned folders and their items.
  • You can whenever switch from Reporter access to admin one and vice versa.
    Note: the latest DSM and Data Collector versions enabled getting all data via Reporter role.

    In both cases you have to create a user on all storage and on Enterprise Manager/Data collector where you have to attach those storage under that Reporter or admin account.

Storage connectivity

  • Install the Enterprise Manager or DSM Data Collector and attach there your Compellent boxes.

  • Create user xormon on the Enterprise Manager or DSM Data Collector under admin role.
    Unfortunatelly admin role is only the role which can get all performance data from the storage.

  • If you use web tool Unisphere central for SC series then registration there is not enough.
    You have to register storage for user in Enterprise Manager or DSM Data Collector.

  • Allow access from the XorMon NG host to the Enterprise Manager on port 3033 (HTTPS).

  • Set "Report gathering settings" of IO usage to 5 minutes.

XorMon NG storage configuration

  • Add storage into configuration from the UI:
    XorMon NG UI ➡ Settings icon ➡ Device ➡ Storage ➡ New ➡ Vendor:device ➡ Dell SC series
    Dell Compellent Dell SC-Series Storage monitoring

  • On the picture you can see 3 compellent storage in the Enterprise Manager.
    Dell Compellent monitoring schema
    Configure every storage you want to monitor, use same storage name alias as you see in the Enterprise Manager.

  • Run "Test" for configured storage device, it must show "OK"

  • Wait about 1 hour, then reload the web browser, you should see it in XorMon NG UI

Storage agent uses eithre the EMC Unisphere as data source, or the storage itself (that method works at least on 5978_711/0365 storage firmware and newer, most probaly even on olders)
EMC Unispheres 1.6.x, 8.x, 9.x and 10.x are supported.
Read why TDEVs are not monitored.

Prerequisites

  • Allow access from the XorMon NG host to the EMC Unisphere or to the storage itself depends on mode you use on port 8443 (TCP).

Troubleshooting

  • DD refuses some ssh sessions, you can find in XorMon NG log (~/xormon-ng/server-nest/log/datadomain) this:
    Error: Unable to connect to remote machine (dd01) : No such file or directory
    Error: Error command: ssh login failed  unable to load Perl module IO::Pty: Can't locate IO/Pty.pm ...
    
    Increase DataDomain parameter login-max-active, xormon ssh sessions are in conjuction with normal backup sessions.
    sysadmin@dd(active:0)# adminaccess option show login-max-active.
      Adminaccess option "login-max-active" set to "150".
    sysadmin@dd(active:0)# adminaccess option set login-max-active 500
      Adminaccess option "login-max-active" set to "500".
    
Isilon v7.x, v8.x and v9.x firmwares are supported.
When you use Isilon v9.x then just use one Management IP Address from the Cluster (do not use direct Node's IPs).
The product uses EMC Isilon REST API interface natively provided by the storage to get all necessary data.

Storage connectivity

  • Allow access from the XorMon NG host to the EMC storage on port 8080.

  • Create user xormon on the storage with new read-only role called xormon.
    $ ssh -l admin 192.168.1.1
    isilon01-1% isi auth users create xormon --enabled yes --password-expires no --password XXXXXXX
    isilon01-1% isi auth roles create --name xormon --description "Read-only role for XorMon NG"
    isi auth roles modify xormon   --add-user=xormon --add-priv-ro=ISI_PRIV_EVENT --add-priv-ro=ISI_PRIV_LOGIN_PAPI --add-priv-ro=ISI_PRIV_STATISTICS --add-priv-ro=ISI_PRIV_SMARTPOOLS --add-priv-ro=ISI_PRIV_DEVICES --add-priv-ro=ISI_PRIV_QUOTA

The product uses EMC ME4 SMI-S and WBI API interfaces natively provided by the storage.

Note: storage firmware GT280R010-01 does not provide data via SMI-S (up to GT280R009-02 it is fine), it is a confirmed issue in the storage firmware (SR #14853424). Upgrade to GT280R011-01 or use WBI access method.

Storage connectivity

  • Allow access from the XorMon NG host to the storage on ports 80 (WBI) and 5988 (SMI-S).
    If you use https and secure SMI-S then test ports 443 and 5989 instead.
    If you use storage cmd line configuration like in examples below (you can use the storage UI instead) then port 22 (ssh) must be open.

  • Make sure that secure SMI-S (port 5989) and WBI HTTPS (port 443) protocols are enabled on the storage
    • CMD line:
      $ ssh -l manage <storage_hostname>
      # show protocols
        Service and Security Protocols
