Linux appmon client aborts after running successfully the first time



Anybody know why the Appmon client aborts with this message in linux?

After several try/error attempts I found the following workaround: remove these files:

cd ~/.Dynatrace/Dynatrace 7.1/client/conf

rm *salt .*bkp

Thanks in advance.

The only think I have in mind that maybe there is some problems with files permission and Dynatrace is not able to overwrite data. But it is just guessing...

As a really ugly workaround you can create short bash script that will be first cleaning this directory, and then starting dynatrace client. But I think there should be some easy solution

Try opening the client once with the option:

Something Like:
$ ./dtclient -Dclearcerts

Then, close and open it up as usual.

If doesn't solve the problem, open a support ticket and let us know the number here:


Hi Gabriel,

Thank you very much. I followed your suggestion and now is working fine.

Kind regards,
