Unfortunately, CentOS 6.10, with rrdtool-1.3.8-10.el6.x86_64.  I didn’t realize rrdtool had changed that much.  I’m already in the long-slow process of migrating Observium to CentOS 7 now.

Subject: Re: [Observium] rrdtool PREDICT error

 

Hi Adam,

 

What distribution is this running on, and where did the rrdtool binary come from (and what version is it)?

 

This looks like the specific rrdtool binary involved doesn't have PREDICT support. 

 

BTW, you're not missing much. It'd do a great job as a 1970s weatherman...

Hi, we’re using 19.5.9872 (7th May 2019), and are seeing an error in graph drawing: when we choose “Graph Trend” on any graph (that I’ve tried so far), I just get “Error Drawing Graph”.

Showing the RRD command also shows the error:

                RRDTool Output: ERROR: invalid rpn expression in: 586400,-7,1800,inbits,PREDICT

 

(full output shown below)

Is this a known problem?

Thanks,

-Adam
