I’m afraid I have no experience with OpenNebula’s XML-RPC interface but according to docs maybe you can try to get some info using the action. Sorry I can’t send you a code snippet but haven’t tried the API directly and also it would depend on your programming language.

By default logs are stored in the /var/log/one directory and you can find logs there for the opennebula service, sunstone service… Also each machine has a log with the VM ID followed by *.log e.g (0.log, 1.log…). Have a look at to find more about log configuration (e.g sending logs to other systems like syslog).



Thanks for the reply:slight_smile:

What is time format of log time of virtual machine in log file in var/log/one path? Which country format is it?

English date, I guess. Anyway it doesn’t seem very difficult to parse, isn’t it it?

This is a sample though you have plenty of it in that folder to play with: Wed Oct 5 11:47:09 2016 [Z0][VMM][I]: Driver loaded.

Check your parser or favourite programming language documentation to know how to parse that dates… seems standard so you’ll find many examples. I can’t share a code snippet as I haven’t done that in the past, sorry.


The format is as ctime(t) which is string representation of
<day of week> <month> <day of month> <hour>:<minute>:<second> <year>
