Monitoring a Netapp is important, the "unofficial" Monitoring NAbox is installed like a slice of cake.
If you never heard about it - check it out here .. https://nabox.org/
But it does not collect the "capacity" information of his objects (volumes and aggregates) without the help of a OCUM (or Active IQ Unified Manager) .
Instead of installing another Appliance you can collect the needed data from Netapp Systems running Ontap 9.6+ by NAbox itself per REST-API.
First create a authentification certificate (which is usable for Powershell too, see my next post) :
Log into the NABox with SSH - (root:NetappGrafanaVA are the default login credentials).
mkdir /opt/myontapcol/
openssl req -x509 -nodes -days 3650 -newkey rsa:2048 -keyout /opt/myontapcol/ontapkey.key -out /opt/myontapcol/ontap.pem -subj "/C=DE/ST=WONDERLAND/L=EMERALDCITY/O=IT/CN=nabox"
BE AWARE OF "CN=nabox" this will be the user which we configure in the next step.
cat /opt/myontapcol/ontap.pem
connect with a 2nd SSH Shell to the Netapp and run this command, take the output from above into clipboard, you need to paste it.
security certificate install -type client-ca -vserver mycluster
it sometimes needs 3 "enter".
security ssl modify -client-enabled true -vserver mycluster
security login create -user-or-group-name nabox -application http -authentication-method cert -role readonly -vserver mycluster
your netapp answers now REST API requests,
You can test it on the nabox shell with
curl -s --key /opt/myontapcol/ontap.key --cert /opt/myontapcol/ontap.pem -k https://ontap-a.acme.corp/api/storage/aggregates
Now lets a script feed the NABox with data, except the python extension jsonpickle the nabox have all neccesary things allready installed.
pip install -U jsonpickle
I uploaded the script here .. naboxcapacol unzip the file open up the naboxcapacol.py file with notepad.
[UPDATE - Newer NA Boxes do not use the port 2004 and use 2013 for pickles counter - find the config file with ps -au|grep carbon and grep -A 5 ^.pick /etc/go-carbon/go-carbon.conf ]
Copy the script into the file and save it.
nano /opt/myontapcol/ontapcapacol.py
#make it executable
chmod +x /opt/myontapcol/ontapcapacol.py
#and let it run every 5min
crontab -e
*/5 * * * * /opt/myontapcol/ontapcapacol.py >> ~/cron.log 2>&1
# after 1h take a look for some of the data

You can now import my "simple" capacity dashboard ontapcapacol.json from the zip or just create your own. I created this for a customer who is not using so much qtrees.
The dashboards which came with harvest are not connecting volume and aggregate together, if you want to have the data here you have to alter the script in a way that it pumps the data to this paths.
