NetApp-Harvest 1.6.1 updater + some news about Harvest 2.0

[vachagan_gratian]

Dear Harvest users,

First of all, apologies for not responding to your questions lately, I was too busy but I'll try to get back to unanswered messages during the next week. Here is some good news: we released a Harvest updater to fix some issues in Harvest 1.6 and add some requested features. We don't go for an official release, since that would take a lot (more) time. The updates include:

• Support for SSL authentication in Harvest Extensions
• Fixing bug in the extension snapmirror_replications.py
• New extension to collect capacity counters (without OCUM)
• Caching resolved Graphite hostname (previously sending metrics to Graphite could add pressure on your DNS if caching was not configured in your server/network).

Here is how to run the updater:

• Download the updater package here
• Verify MD5 checksum:

$ md5sum harvest_updater_161.tar.gz 
> 1923977dee44366080ca19e724ad4650  harvest_updater_161.tar.gz

• Unextract the package somewhere on your Harvest server, e.g.:

$ tar -xzvf harvest_updater_161.tar.gz -C /tmp/

• Stop all harvest pollers
• Run the updater:

$ cd harvest_updater_161/
$ ./harvest_updater

• Restart Harvest

The updater adds three Grafana dashboards which you'll need to manually import in the Grafana webgui to use/update them:

/opt/netapp-harvest/grafana/db_netapp-detail-nfs-connections.json
/opt/netapp-harvest/grafana/db_netapp-detail-snapmirror.json
/opt/netapp-harvest/grafana/db_netapp-detail-volume-capacity.json

Reversing the update. Before the updater changes any files, it will create a backup in /opt/netapp-harvest/backup/harvest_updater_16100/, so if something goes wrong, you can reverse the update by:

$ ./harvest_updater --reverse

Second of all, many of you are asking about Harvest 2.0 and about replacing Graphite. We are well aware of the scalability issues of Graphite, and while we will continue supporting Graphite, our main backend in Harvest 2.0 will be (most likely) Prometheus. Unfortunately I can't give estimation of a release date, since at the moment we are trying to get more manpower behind this project, but I can tell you that Harvest 2.0 is our main focus at the moment.

Finally if by any chance you have written a Python module to send performance metrics to Prometheus and you want to contribute to an open-source project (Harvest 2.0 will be on Github!), please get in touch with me.

Cheers,

Vachagan

And it's expired again.

I'll do the 1.6 update anyway (9.7 update broke our old 1.4 install) but either 1.6.1 needs to be rounded up into the normal download package or... 1.7?

(I know this is rough, since time is better spent getting 2.0 ready!)

@vachagan_gratian  The download link for 1.6.1 has expired again. You may want to make a full release or host the file elsewhere as this isn't working well...But regardless, can you post an updated link? Maybe also update the link in the first post so users who find the thread get a working link to start with without having to spelunk through the replies?

[vachagan_gratian]

@cprivitere Thanks for alerting and sorry for the inconvenience. I updated the link and it should work now again.

Few questions here.

1. If backed of harvest 2.0 is moved to Prometheus, are you providing any tools to migrate existing data from whisper to Prometheus? We have metrics for last one year and don't want to miss these metrics if we plan to move to Prometheus.

2. Will harvest 2.0 continue to utilize/use netapp-harvest.conf file for polling clusters? Will this file continue to be source of harvest poller service? 

[vachagan_gratian]

Hi,

1. we are still looking for solutions, there are some tools available for migrating from Graphite to Prometheus, but frankly, we did not had the time to investigate this thoroughly.

2. yes, the configuration set-up will be very similar to what we had before: one configuration file that defines your targets and exporters and template files that define what metric objects/ counters  to collect.

Sorry, the link has expired.
The link was set to expire after a certain amount of time. Please contact the person who shared this link with you.

Any chance you can repost the files to update to 1.6.1?
Any news on release date for 1.7?

[cprivitere]

@vachagan_gratian  The 1.6.1 download link is expired again. Can you please update it and the follow up patches you posted in the thread? 

[unixadmins]

Hi,

      can someone share the harvest 1.6.1 or it will be uploaded in the support site section https://mysupport.netapp.com/site/tools/tool-eula/netapp-harvest/download ?

Thanks

Harvest 1.6.x is not supported and has been removed from the tool chest. Please use Harvest 2.0 instead.
