Collectd-swap: no graphical representation

I'm running Openwrt 21.02.1 on an Archer C7 V5. Everything okay so far.

I've installed zram-swap to ease the small amount of RAM (128 MB). In order to watch the usage of the swap device I installed collectd-mod-swap.

But nothing happened. Under Statistics/Setup there's no entry for the swap plugin nor under Statistics/Graphs a graph.

As next step I created the file /etc/collectd/conf.d/swap.conf with the following content:

LoadPlugin swap

<Plugin swap>
	ReportByDevice true

Now the swap plugin is loaded,
Dec 5 14:42:39 daemon.err collectd[7905]: plugin_load: plugin "swap" successfully loaded.
but furthermore I have no entry under Statistics/Setup nor a graph under Statistics/Graphs.

I verified, that collectd is collecting data for the swap device,

-rw-r--r-- 1 root root 70604 05.12.2021 14:54:30 /tmp/rrdata/H2O-PIANO/swap-dev_zram0/swap-free.rrd
-rw-r--r-- 1 root root 70604 05.12.2021 14:54:30 /tmp/rrdata/H2O-PIANO/swap-dev_zram0/swap-used.rrd

but there is no graphical representation.

I suspect, that I'm missing something, but I don't know what. Can anybody give me a helping hand?

Support for that plugin has never been implemented in LuCI statistics.
It is so rare.

What a pity! :frowning_face:

You can try adding support for it.
The addition requires in practice that you have the swap plugin database for testing, and you have it now.

Here is example, how I added chrony plugin a while ago.

I tried to follow the link, but get an error, when accessing it:

Is github being hacked? Or is there any other reason?

No idea what you are talking about. The page opens quite normally...

Same here with firefox, the error appeared in chromium. :frowning_face:

Thanks for your feedback.
