Hello all,
I did a setup of Collectd in a VM with OpenBSD 6 installed to collect
data and write to RRD files (RRDTool).
Everything seems to be running OK, but all my attempts of generating
charts are resulting into something like this:
https://www.dropbox.com/s/uudpcujsgbbtrfe/salompas_spo_virtua_com_br_cpu-0_cpu-system.png?dl=0
It's a bit hard to describe (there is a data curve at right, small
because I'm running for a few minutes only), but it seems all strings
that were supposed to be there were replaced by rectangles. I tried
generating charts from all 3 Perl solutions available in the Collectd
contrib tarball and also with rrdscout (Python based), all producing the
same results.
If I would have to guess, I would say it is something with RRDTool libs
and/or graphic related libs. I tried to follow up all requirements from
RRDTool website, installed them over OpenBSD (even though the related
package didn't required them), but results remain the same.
That is happening for all resources I'm monitoring (CPU, load and memory).
I can share the RRD files if necessary, this is for a free software
project anyway (https://github.com/glasswalk3r/cpan-openbsd-smoker).
Please let me know if any of you already experimented this kind of problem.
Thanks in advance,
Alceu
