Disable new plugins by default

[Haw Loeung]

Hi,

Just upgraded the telegraf charm in one of our environments deployed to a public cloud and found that it was spamming us with sudo errors, LP:1891781. On inspection, it seems like a bunch of new plugins have been enabled:

buddyinfo.conf
netns.conf
ovs_dpctl.conf
ovs_dump_flows.conf
socket_listener.conf
sockstat6.conf
sockstat.conf
softnet_stat.conf
zoneinfo.conf

Half of that are OpenStack related, buddyinfo and zoneinfo for NUMA, OVS for OpenvSwitch. Can we please disable all new plugins by default to avoid future surprises? These additional plugins can be enabled via something like enable_plugins config option. I understand there is currently a 'disabled_plugins' but this means every time we roll out the latest charm, we need to check and disable any new plugins.

It might make sense to gate these on a relation to another application, for example to enable the OVS plugins one might add a relation to neutron-openvswitch.

Workaround to disable all these new telegraf_exec_metrics ones:

| juju config telegraf-u-r-c disabled_plugins="buddyinfo:netns:ovs_dpctl:ovs_dump_flows:sockstat:sockstat6:softnet_stat:zoneinfo"

Please see https://bugs.launchpad.net/charm-telegraf/+bug/1919262 - we've disabled a bunch of checks in LXD which overwork lxcfs. Does the associated change also fix this, or do we have a separate issue?

OVS is gated on whether OVS is available on the host, so that shouldn't be an issue if you don't have it.
