RRD error: Could not save png to '' - Proxmox 5

[BelCloud]

Hello

I'm getting the following error on proxmox 5, when trying to access rrd.

pvesh get /nodes/jx213-s20/lxc/105/rrd -ds cpu -timeframe day

RRD error: Could not save png to ''

It's working well on proxmox 4.

I've just dist-upgrade today, but did not solve the issue.

Anyone's got an idea?

hmm, it seems something has changed in the perl rrd modules,
can you please open a bugreport on https://bugzilla.proxmox.com/

 

[dcsapak]

but a question, do you really need the pngs ? you can get the data directly via /rrddata and then use them as input for whatever you want

They are very usefull, as i don't need to write my own graphing system

Will open a bug report now.
