Users connected

[phm]

Hi,

Is there a command to know the connected users ?
And secondly, when I shutdown or run the OMERO server I have a mail from omero. However when I try to send mail to users via the web client The email does not arrive to its destination.

Hi Philippe,

Is there a command to know the connected users ?

In what context? E.g. from the CLI as the "root" OMERO user?

And secondly, when I shutdown or run the OMERO server I have a mail from omero. However when I try to send mail to users via the web client The email does not arrive to its destination.

What does the mail look like? Did you configure the new mail support? If so, can you share your configuration with us? Having the OMEROweb.log and Blitz-0.log from var/log for one failed attempt to send email would be useful.

Thanks,
~Josh.

In the web admin it will be nice, however in command line as an omero comand

Code: Select all

omero.mail.config=true
omero.mail.host=localhost
omero.mail.port=25
omero.web.admins=[["Philippe Mailly", "philippe.mailly@college-de-france.fr"]]

And nothing in OMEROweb.log

Finally, after checking my server log it was because the mail was refused by the IT service ....

Hi Josh,

And what about a command to know the connected users. It's will be very useful for shutdown the server or for maintenance. Or how to know if some people transfer images ?

Hi Philippe,

I will usually grep the Blitz log, for `user=` lines, though Josh has recommended using HQL to query the event log, as follows (replacing the date/time with whatever time you're interested in):

Code: Select all

/opt/omero/OMERO-CURRENT/bin/omero hql "select e.experimenter.omeName, count(e) from Event e where e.time > cast('2015-04-22 16:00', timestamp) group by e.experimenter.omeName" -q | egrep -v "root|sysadmin-userid|PUBLIC|guest"

Here's my Blitz log grep - but point to note, the above HQL seems to return the same users shown up in my Blitz log parse, and a few more. Since I'm not sure why that is, I usually run both.

Change the '[0-5]' to whatever minute range in the current hour you're interested in.

Code: Select all

cat /opt/omero/OMERO-CURRENT/var/log/Blitz-0.log | grep "$(date +%Y-%m-%d' '%H:)[0-5]"  | grep 'user=' | awk '{ print $8 }' | sort | cut -d',' -f1 | uniq | cut -d'=' -f2  | egrep -v '0' | xargs OMERO-CURRENT/bin/omero user info  --user-id

And I'll do a `tail` of the web server log, too, to see if there are existing sessions to OMERO.web.

Hope that's of some us.

All the best,

Kenny

Thank Kenny you for "tips" is a bit difficult to remember..... An omero command like omero who_is_online could be very nice.

Agreed, Philippe. Already added a card to add the necessary methods. Thanks for the idea.

Cheers,

Hi Philippe,

Just in case you're still watching this thread, I was just using the OMERO CLI command inspired by this thread, and thought I'd add it's help text here for reference.

This feature was implemented in the CLI and is now available with OMERO 5.1.2.

Code: Select all

[omerouser@server OMERO-CURRENT]$ bin/omero sessions who -h
usage: bin/omero sessions who [-h]

List all active server sessions

Administrators will receive a list of all active sessions
along with critical information on last activity. This is
useful for determining whether or not the server can be
restarted.

Other users will only see a list of names, i.e. users who
can be considered "online".

Optional Arguments:
  In addition to any higher level options

  -h, --help          show this help message and exit
