[Thinlinc-technical] How to list sessions ?

[Carsten John]

Hi Philippe,

I have a few command line scripts here, that may fit your needs (all quick-and-dirty hacks):

------------------------------------------------------------------------------------------------------------------------
count_connected_session.sh:

#!/bin/bash
# make sure $HOME is set as wget reads ~/.netrc for login/password
export HOME=/root/
COUNT=0
OOSERS=$(ps -efa | grep "[t]l-session: " | awk '{print $9}' | sort | uniq )
for OOSER in $OOSERS
do
    DISCONNECTED=$(wget --quiet -O - https://login.mpi-bremen.de:8080/status/sessions?details=$OOSER#anchor | grep -c "disconnected")
    if [[ $DISCONNECTED -eq 0 ]]
    then
        COUNT=$((COUNT + 1))
        echo "$OOSER  is connected"
    fi  
done
echo $COUNT 



---------------------------------------------------------------------------------------------------------------------------
count_disconnected_session.sh

#!/bin/bash
# make sure $HOME is set as wget reads ~/.netrc for login/password
export HOME=/root/
COUNT=0
OOSERS=$(ps -efa | grep "[t]l-session: " | awk '{print $9}' | sort | uniq )
for OOSER in $OOSERS
do
    DISCONNECTED=$(wget --quiet -O - https://login.mpi-bremen.de:8080/status/sessions?details=$OOSER#anchor | grep -c "disconnected")
    if [[ $DISCONNECTED -eq 1 ]]
    then
        COUNT=$((COUNT + 1))
        echo "$OOSER is disconnected"
    fi  
done
echo $COUNT 

---------------------------------------------------------------------------------------------------------------------------------------------

kill_idle_session.sh:

#!/bin/bash
# if a session is disconnected and no application is started licenses are needlessly eaten up 
# make sure $HOME is set as wget reads ~/.netrc for login/password
export HOME=/root/
OOSERS=$(ps -efa | grep "[t]l-session: " | awk '{print $9}' | sort | uniq)
for OOSER in $OOSERS
do
    # make sure user is disconnected (might just have logged in and still not started an application)
    # so far there is no easy way to get session state, but the webgui
    DISCONNECTED=$(wget --quiet -O - https://login.mpi-bremen.de:8080/status/sessions?details=$OOSER#anchor | grep -c "disconnected")
    if [[ $DISCONNECTED -eq 1 ]]
    then
        # all our wrapper script live in /usr/local/bin
        # if there are no pprocesses started from there, the session is idle
        if [[ $(ps -f -u $OOSER | grep "/usr/local/bin/") = "" ]]
        then
            TLPID=$(ps -efa | grep "[t]l-session: " | grep $OOSER |awk '{ print $2}')
            echo "$OOSER has idle session $TLPID, killing"
            kill $TLPID
        fi
    fi  
done
