Grafana and netapp-harvest error

Johann_ohne_Land

Hello,

 

I followed the instructions in the IAG  and installed

Netapp harvest 1.6.1

Grafana 7.3.6

Latest Graphite and Carbon-cache from GIT.

Installtion worked fine up to running 

 

/opt/netapp-harvest/netapp-manager -import

here I get the following errors

 

"[OK ] Line [29] is Section [global]

Harvest is running fine, I can see the data in Grapite webapp itself, the wsp files and other data files get updated properly.

I don't see anything in Grafana though, the Netapp Dashboards are not there, and of cause no data.

 

Anyone a hint what I'm missing and what the error means.

 

Thanks

Quick update

 

I manually imported the json files to Grafana and can see all the data now.

 

If someone has an idea why the netapp-manager import failed, please let me know.

x.y.z.a is you replacing the server name in the logs right ?

 

I'm assuming in [global] section there is an error in grafana_url.

This should be an actual URL, not just an ip address or host name (with http(s):// and all...)

Hello x.y.z.a is a replacement for the correct IP.

I actually tried http://x.y.z.a:3000 and https://x.y.z.a:3000 as well localhost:3000, same results.

Manually importing the json files worked though.

i will do some further checking and keep you posted.

For reference, this is the relevant portion of code :

 

        if ($conf{global}{grafana_url} =~ m!^(([^:/?#]+):)?(//([^/?#]*))?([^?#]*)(\?([^#]*))?(#(.*))?!)
	{
		$addr = $4;
		$port = 80 if ($2 eq 'http');
		$port = 443 if ($2 eq 'https');
		if ($addr =~ /(.*):(\d{1,5})/)
		{
			($addr, $port) = ($1, $2);
		}
	}

It looks like $addr is undefined, so the regexp matched but group $4 is empty for some reason.

 

In the logs you posted it makes sense because you didn't put protocol://

Let's do the same thing with http://grafana-ip:3000/ instead.
