Performance data collection issue with ONTAP 9.3

dhm

I have added a Netapp FAS8040 running ONTAP 9.3. All the configuration is shown, but no performance or capacity information is displayed.

The error log shows:

Stor2rrd version is 2.61

Hi,

1. do you have installed xmllint?

xmllint --version

2. send us logs

Note a short problem description in the text field of the upload form.

cd /home/stor2rrd/stor2rrd # or where is your STOR2RRD working dir

tar cvhf logs.tar logs tmp/*txt

gzip -9 logs.tar

Send us logs.tar.gz via https://upload.stor2rrd.com

Hi Pavel,

I have uploaded the logs as requested.

# xmllint --version

xmllint: using libxml version 20901

Hi,

this will not work, you have to run it every 5 minutes from crontab

# NetApp FAS : C-mode
0,30 * * * * /opt/stor2rrd/load_netappperf.sh > /opt/stor2rrd/load_netappperf.out 2>&1

-->

0,5,10,15,20,25,30,35,40,45,50,55 * * * * /opt/stor2rrd/load_netappperf.sh > /opt/stor2rrd/load_netappperf.out 2>&1

same with other storages you will not have correct results running it in different schedulle than 5 minutes

0,15,30,45 * * * * /opt/stor2rrd/load_vnxperf.sh > /opt/stor2rrd/load_vnxperf.out 2>&1

0,10,20,30,40,50 * * * * /opt/stor2rrd/load_datadomainperf.sh > /opt/stor2rrd/load_datadomainperf.out 2>&1

Hi Pavel,

Changing the Netapp cron entry to every 5 minutes has worked. I now have performance data being shown.

The VNX and DataDomain arrays do provide performance and capacity data. I may look at increasing the VNX schedule, but the DataDomains (full DD9800 with lots of mtrees), almost can't complete the data collection when running every 10 minutes.

One thing that would be potentially useful is Netapp per volume capacity data, so that a volumes capacity can be charted.

Thanks,
David

Hi,

ok, DD will work fine with 10 minute schedulle.

we do not save volume capacity data on any storage we support, might be in the future ..
