I'm looking for a track/log of instance management done using CLI nova commands and from Horizon such as creation, reboot, shutdown,deletion etc.

Does anyone know where I can find the log?

Also I would like to know what application do you use for tracking such logs.

Last time I checked (about a year ago) the best way was to listen on various notifications OpenStack was publishing to RabbitMQ. From here you could parse and save relevant events to mysql,logstash,whatever.

I have used StackTach (v2) for this, it is a lightweight python app which did the job OK. StackTach v3 seemed to complex back then, an overkill for what i was trying to do.

Thank you. Is StackTach better than Logstash if you know.

I don't think i can compare them,with StackTach (which is pretty lightweight),I can easily dig trough Instance related events,find out how much time was spend executing each,etc.While Logstash would be better used to collect project wide logs as a way to monitor your complete infrastructure.

Use nova --debug your-command and you can watch out the back end process
