Free storage performance and capacity monitoring
STOR2RRD generates historical utilization graphs of monitored storages.
It retrieves performance data via the storage API.
It collects and presents complete logical configuration of all storages.
It graphically presents IO rate, data throughput and response times for all Ports, Pools, Ranks, Mdisks, Volumes (LUNs) and drives.

Announcements in brief

  • 1.00: new GUI, many new metrics, enhanced historical reporting
  • 0.40: Support of IBM SVC® and Storwize® storage family

How it works

  • The tool itself is installed on a unix server together with the web server and storage CLI
  • Storage CLI is configured to access defined storages via a user with minimal user rights (monitor role for DSCLI)
  • There is scheduled download of performance data every 5 minutes for each configured storage and data is stored in RRDTool DB files
  • Aggregated graphs are refreshed every hour or via a "refresh" link on demand
  • Rest of graphs are created on demand
  • The product actually supports:
    • IBM System Storage DS8000® series except storages attached to mainframes (IBM System z®)
    • IBM System Storage DS6800® series except storages attached to mainframes (IBM System z®)
    • IBM Storwize® family
    • IBM SAN Volume Controller® (SVC)
    • IBM XIV® (will be available in Nov 2014)

Why use STOR2RRD?

  • It comes with the same philosophy as its sister product LPAR2RRD.
    Get information you are looking for in 2 - 3 clicks!
  • You can find utilization of any attached storage in a simple graphical form understandable from technician to management level
  • It is free for use, you do not need to invest into expensive commercial solutions
  • It does not require ANY administration as soon as it is initially setup
    in comparison to other commercial tools where you need to have dedicated and trained staff for their administration

 

  • It monitors all important physical and logical subsystems of the storages like ports, pools, ranks, mdisks, volumes (LUNs) and disks in 5 minutes intervals
  • It creates IOPS, data throughput and response times graphs of thoses subsystems
  • It collects "Physical and Logical configuration" : Summary and Detail examples
  • Simple to install, configure and use - initial installation & configuration together with dependency tools should not take more than an hour!
  • It can be hosted on any UNIX platform, it just needs the storage API, web server, Perl and RRDTool installed.



  • This is not replacement of tools like IBM Tivoli which monitors storage in deep detail
  • It should act as the front-end tool which easily and quickly helps with identification of load abnormality and locates it. For further deeper analysis is necessary to use storage native tools.







Next major areas we are going to focus are:
  • IBM XIV support will be available at the end of Nov 2014 (v1.10)
  • IBM FlashSystem storage will be supported soon (v1.10?)
  • EMC and Hitachi storages
  • Alerting
    It will be able to raise an alerts if anything (pool,port,rank or volume) exceeds defined threshold
