I would like to find out when Datameer service was brought up/down last time, is there a way?
Take a look at the file jetty.state located under <Datameer_Home> directory.
If the last line starts with STARTED, the last action was the service was brought up.
If the last line starts with STOPPED, the last action was the service was brought down.
Timestamp of the file itself shows the time at which the above action was taken.
