Performance data collection issue with ONTAP 9.3

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:

    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.

    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 ..
