Instead of being a boolean value (on/off), it can take a range of integer values.
Other tasks are then triggered when the meter reaches a certain value.
Ecf Script¶
We will create new tasks (t5, t6 and t7) that will be triggered
when the meter in task t1 reaches certain values.
To notify ecflow_server, the task ( t1 in the example below) must call
the ecflow_client –meter. This is also one of the child command‘s.
%include <head.h>
echo "I will now sleep for %SLEEP% seconds"
sleep %SLEEP%
n=1
while [[ $n -le 100 ]] # Loop 100 times
do
sleep 1 # Wait a short time
ecflow_client --meter progress $n # Notify ecFlow
(( n = $n + 1 ))
done
%include <tail.h>
Text¶
# Definition of the suite test.
suite test
edit ECF_INCLUDE "$HOME/course" # replace '$HOME' with the path to your home directory
edit ECF_HOME "$HOME/course"
family f1
edit SLEEP 20
task t1
meter progress 1 100 90
task t2
trigger t1 eq complete
event a
event b
task t3
trigger t2:a
task t4
trigger t2 eq complete
complete t2:b
task t5
trigger t1:progress ge 30
task t6
trigger t1:progress ge 60
task t7
trigger t1:progress ge 90
endfamily
endsuite
Python¶

What to do:
- Edit the definition file or python to add the modifications.
- Edit t1.ecf to call ecflow_client –meter
- Copy t4.ecf to t5.ecf, t6.ecf and t7.ecf
- Replace the suite
- Observe the tasks in ecflowview.
- See the triggers by selecting progress and clicking on the Triggers icon.
- Move the mouse pointer over then with the right mouse button, choose Edit...
- Modify the value of the meter and click on the Apply icon
