At work we use the syslog log driver for docker. Essentially any container stdout gets pushed in to the system syslog that then gets ingested into splunk through one of their forwarders. We needed more than just container logs so that’s the reason for that. For a home setup I’d probably do the same but use the ELK stack instead of splunk.
The key item here is that “combat losses” is what is being tracked. This means KIA as well as Wounded in Action. The actual Russian death count is definitely lower from my understanding but the result is the same. ~300k Russians troops are no longer able to participate in this war.
To add to this I think Russia not too long ago accidentally leaked something close to the actual number deaths. It was around 120k I believe.
