NetApp-Harvest cDot Poller Stop Working

mehliku — Wed, 04 Jun 2025 13:16:44 GMT

I have the current setup for NABOX:

Debian GNU/Linux 8 (jessie) (8.7) Visit Web Page

NetApp SDK v9.4
Harvest v1.4
Grafana v4.6.3
Graphite v1.2.0
Elasticsearch 5.6.5
Logstash 1:5.6.5-1

I have 7-mode and cDot data being collected.

The 7 mode pollers are working fine and collecting.

With cDot however, i have to stop/start the pollers daily, as they stop working.

The NABOX still shows them working but, when looking at the Grafana Poller screen, i can see there are no metrics being collected.

Once i stop/start the poller, i can then see them working after a few mins.

To investigate this further, i started one of the cDot pollers in verbose mode. Below ive pasted a few messages ive picked out.

This message comes up when starting the poller in verbose:

[xxxxxxxxx] key [site] is depreciated; aliasing to [group]. Rename [site] to [group] to remove this message.

The next set of messages is from /opt/netapp-harvest/log, from the cdot poller log

When the poller stops working, the last set of messages are:

[2018-09-25 17:02:08] [DEBUG ] [lun] Starting new poll data batch [0 to 8 of 8], batch size is [500]

nothing further

Check out the Harvest 1.4.1 . It contains some fixes to the collections stopping unexpectedly. I updated my Harvest with the new zip file and it was pretty painless. This also adds some additinal FlexGroup features.

Unfortunately Harvest 1.4.1 doesn't fix this issue properly (mea culpa). But I will provide a patch to fix that soon. I recommend to upgrade to 1.4.1 and stay tuned for the patch.

And if you face other issues, please let us know 🙂
