Update NetApp-Harvest to 1.6.1 version from 1.6

IAAS-Storage

Hello,

 

I installed the version 1.6 of NetApp Harvest but I could't make it work the new dashboards for snapmirror and nfs connections.

On the other hand I tried to update from 1.6 to 1.6.1 for getting the new capability with the added extension of capacity.

In my conf file netapp-harvest.conf I changed the next line:

template          = default

for this other:

template          = default,extension.conf                                                                                                                                                                                                                                     

 

Also I create the template file extension.conf in the dir /opt/netapp-harvest/template. I have both scripts (bash and python) for gathering the information related to snapmirror and nfs connections:

/opt/netapp-harvest/extension/snapmirror_replications.py
/opt/netapp-harvest/extension/nfs-connections.sh

 

I've checked the logs file in both cases:

For add more information, I reviewed the information which harvest gather in the location /opt/graphite/storage/whisper/netapp/perf/*group*/*Cluster*/node/*nodecluster*/ and I don't have the information which grafana usess to graph the data.

total 12

Previously of opening this issue, I have checked all topics related with this and I tried to fix it without success.


Please, could you help?

 

Thanks.

Hi,

 

For the snapmirrors extension, we are aware of the issue, but haven't fixed it yet.

If you can, I would advise to follow the suggestion here and add the following lines to the snapmirror extension script:

import ssl
try:
    _create_unverified_https_context = ssl._create_unverified_context
except AttributeError:
    # Legacy Python that doesn't verify HTTPS certificates by default
    pass
else:
    # Handle target environment that doesn't support HTTPS verification
    ssl._create_default_https_context = _create_unverified_https_context

 just before the main() function.

 

For the nfs extension, could you run it in verbose mode and see what messages you get?

Hello,

 

Thanks for your kind and quick answer.

 

I did the changes, you mention in the python file: snapmirror_replications.py which is located in /opt/netapp-harvest/extension. Is it correct?

 

After the restart of neapp-harvest service, I got the next lines in the log file:

[2020-04-29 14:50:05,475] [DEBUG] Started new session. Will poll host [23.5.16.11] for snapmirror replications

I tried to launch the bash file nfs_connections.sh before but the problem was I don´t know which information I have to add in this parameter.

      -E | --epoch            Fills environment variable _HARVEST_POLL_EPOCH

 

Thanks.

 

Hi,

 

similar problem on my side - NFS statistics doe not get's populated/shown in Grafana.

 

cheers and sorry for hijacking this post if it does not fit to the question

 

Update: I guess it's populated to graphite because I can see values there as seen in screenshot

Update:

 

It looks like that the metric which the dashboard want's to access is not populated in graphite

for example -->

 

aliasByNode(netapp.perf.$Group.$Cluster.node.*.nfsv3.nfs_connections, 5)

 

nfs_connections ... is not in graphite (screenshot attached ...) - and also the search tells me "no matching metrics" 

Hello Florian,

 

In my opinion, the problem is in the python file which doesn´t gather the nfs connections because there is some wrong in our configuration.
Maybe we did some wrong when we installed this new feature or there isn´t something well explain in the documentation file that is why I am waiting for netapp staff to provide us a respond or somebody who fixed this problem yet.

 

Thanks for join and give your inputs.

 

Hey,

 

could be the case yes - let's see 🙂

Hope dies in the end 🙂

 

Cheers
