Description Miroslav Lichvar 2020-01-29 09:06:38 UTC 
Description of problem:
The iptables plugin of collectd doesn't seem to work on RHEL8. I guess this is related to the switch to nftables and its iptables emulation.

With a Chain6 specified in the configuration, the plugin fails with an error on each read.

# cat /etc/collectd.conf 
LoadPlugin iptables

<Plugin iptables>
  Chain "filter" "INPUT" "foo"
  Chain6 "filter" "INPUT" "foo"
</Plugin>

# collectd -T
plugin_load: plugin "iptables" successfully loaded.
iptables plugin: ip6tc_init (filter) failed: iptables who? (do you need to insmod?)
read-function of plugin `iptables' failed.
Error: one or more plugin read callbacks failed.
Exiting normally.
collectd: Stopping 5 write threads.

If I remove the Chain6 line, there is no error, but it doesn't seem to collect any data. The same configuration works on RHEL7.
