Pure Storage monitoring: FlashArray FlashBlade

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 uses Pure Storage FlashArray REST API interface natively provided by the storage to get all necessary data.

Storage connectivity

  • Allow access from the STOR2RRD host to the Pure Storage FlashArray storage on port 443 (https).
    $ perl /home/stor2rrd/stor2rrd/bin/conntest.pl 192.168.1.1 443
  Connection to "192.168.1.1" on port "443" is ok
  • Create user stor2rrd on the storage in read-only group .
    You have to create stor2rrd user in Active Directory as there cannot be created new users on the storage and then map it to read-only group on the storage.
    You might even use pureuser which is available on the storage locally, but it has admin rights.
    Integrating Active Directory with the Pure Storage FlashArray.

STOR2RRD storage configuration

  • All actions below under stor2rrd user (lpar2rrd on Virtual Appliance)

  • Add storage into configuration from the UI:
    Settings icon ➡ Storage ➡ New ➡ Vendor:device ➡ Pure Storage FlashArray
    PureStorage FlashArray Storage management

  • Make sure 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
  • Test storage connectivity, either from the UI or from the command line: 
    $ cd /home/stor2rrd/stor2rrd
$ ./bin/config_check.sh purestorage-alias01
  =====================
  STORAGE: purestorage-alias01 : PURE
  =====================
  connection ok
    If you get an errors like "Missing LWP::Protocol::https", "Connection reset by peer" or "500 SSL negotiation failed" then follow this.

  • Schedule to run storage agent from stor2rrd crontab (lpar2rrd on Virtual Appliance, it might already exist there) 
    $ crontab -l | grep load_pureperf.sh
$
    Add if it does not exist as above 
    $ crontab -e

# Pure Storage agent
0,5,10,15,20,25,30,35,40,45,50,55 * * * * /home/stor2rrd/stor2rrd/load_pureperf.sh > /home/stor2rrd/stor2rrd/load_pureperf.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/

  • Create user stor2rrd on the storage in read-only group .

  • Generate an API Token on the storage:
    Generate an API token through the Purity UI (System > Users > Create API Token) or through the CLI : 
    pureadmin create --api-token
  T-e7e551be-fe5d-4669-baf5-670cd8ea0560
    Do not set an expiration period when creating API token!
    Use the key in storage configuration below.
