Old question I know, still nothing easily found in docs or online...
This would be great to know in a cli or something, since we have hosts with old agents that no longer are registered on the server.
Figured out the following that may help others in resurrecting old systems.
Running version?
cat /opt/dynatrace/oneagent/agent/installer.version
1.163.277.20190318-125829
Also can see lots of versions including "main" with the following:
cat /opt/dynatrace/oneagent/agent/conf/binaries.json
{
"os": {
"main": {
"linux-x86-32": {
"version": "1.163.274.20190318-080539",
"installer-version": "1.163.277.20190318-125829",
"name": "liboneagentos.so"
},
"linux-x86-64": {
"version": "1.163.274.20190318-080539",
"installer-version": "1.163.277.20190318-125829",
"name": "liboneagentos.so"
}
}
},
...
lots of other bits of java / dotnet / sdk / plugins and their versions listed here

Closest way I know to check what is installed on linux is the following as root:
ls -alh /opt/dynatrace/oneagent/agent/bin/
total 8.0K
