Pure Storage FlashArray and FlashBlade Storage Performance Monitoring

Installation

Pure Storage installation

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 REST API interface natively provided by the storage to get all necessary data.

Storage connectivity

Allow access from the STOR2RRD host to the 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)
STOR2RRD v2.60+:
Add storage into configuration from the UI:
Settings icon ➡ Storage ➡ New ➡ Vendor:device ➡ Pure Storage FlashArray

STOR2RRD v2.50 and olders:

Uncomment (remove the hash) example line and adjust it:

$ vi /home/stor2rrd/stor2rrd/etc/storage-list.cfg

#
# Pure Storage
#
# Storage Alias:PURE:IP or hostname:storage user:encrypted password:VOLUME_AGG_DATA_LIM:VOLUME_AGG_IO_LIM:SAMPLE_RATE_MINS
# to encrypt password use: perl ./bin/spasswd.pl
#purestorage-alias01:PURE:pure_host.example.com:stor2rrd:KT4mXVI9N0BUPjZdVQo=:1024:10:
#purestorage-alias01:PURE:pure_host.example.com:stor2rrd:KT4mXVI9N0BUPjZdVQo=

purestorage-alias01:PURE:192.168.1.1:stor2rrd:KT4mXVI9N0BUPjZdVQo=

Above shows the storage with IP 192.168.1.1 which will be visible in the UI as purestorage-alias01

Use encrypted password in storage line above, encrypt it like this:

$ cd /home/stor2rrd/stor2rrd
$ perl bin/spasswd.pl 

  Encode password for storage authentication:
  -------------------------------------------
  Enter password: 
  Re-enter password: 

  Copy the following string to the password field of the corresponding line in etc/storage-list.cfg:

  KT4mXVI9N0BUPjZdVQo=

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
```

Check storage connectivity

$ 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
```
