Recently I had to setup our TPC Server to collect data from the storage devices that I'm responsible for during IBM ISV and Business Partner engagements here at the Hursley IIC. The process for setting up collections for each of the storage units within Tivoli Productivity Centre is pretty much the same but I intend to write a number of Blogs that outline the process for setup and use of this product so that you too can analyse you logical volume performance characteristics.
Firstly you need to setup the servers log information Retention Parameters. These are kind of global to the TPC server and detemine settings for all storage units and volumes being targeted
On the left pane you need to select "Configuration" / "Resource History Retention" and then complete the parts for the Probes and the Monitors. The Probe (which we'll setup later) is the job that goes and interrogates the current configuration of the storage unit , whereas a monitor is actual performance data of volumes. You can see above that I elected to save Probes for a relatively short period of time since I intended to probe on a daily basis because our environment gets ripped down and re-deployed on a regular basis. As for the Monitor data you can see that I only keep the detailed data for each monitor task for 30 days with the hourly averages remaining for longer and the weekly average information for 6 months.
That is it for the retention.
Now to add a Storage Subsystem to be monitored
You need to select the Drop-down for the Device Type of storage you are adding, but before we proceed with this, I should explain that the Subsystem I was adding had to be configured with an SSH session, so I used PuttyGen to generate a key pair and saved and uploded them to a directory on the TPC Server. When generating the V7000 user , I elected to access and download the SSH Public key when generating the V7000 user, in my case "tpcuser".
Here you can see that we elected to access the Public SSH Key for tpcuser.
Now we can proceed with the Storage Unit addition on the TPC Server. In the dropd-own I selected IBM Storewize V7000 , the IP Address of the V7000 (the same as the one you would use for browser access within the V700 GUI) and lastly selected the private key that we uploaded that pairs with the public on the V7000. See the image below.
You will see that there are currently No Connections defined. Click add and your new Storage subsystem will appear. See below.
To complete the process and you need to Click Next -> you can check the logs produced by selecting the magnifying glass beside each on the Discovered Storage Subsystems panel.
The Storage Subsystem has now been discoverd , click next once more to continue to Specifying Data collection. You will have to add it to a Standard collection group initially to complete the process, but we will remove it and create a separate probe later.
Click next to accept the Standard Monitor Group. You'll then proceed to a summary page below.
Select Next to confirm addition of your Subsystem. You will , finally receive the pane below which indicates successful addition of the Subsystem and gives you a message indicating that an initial Background Probe will run when you click the finish button to complete the process.
This has now added a Subsystem to the TPC Server and will have run an initial probe. See my later blogs in the series to get more information on probes, monitors and volume operational statistics.
