Usage of lvalert_admin

  • get a list of existing nodes
    $ lvalert_admin -s lvalert-playground.cgca.uwm.edu --get-nodes
  • create a test node
    $ lvalert_admin -s lvalert-playground.cgca.uwm.edu --create --node test_k1det
    Creating node test_k1det
    Successfully completed operation
  • subscribe a node
    $ lvalert_admin -s lvalert-playground.cgca.uwm.edu --subscribe --node test_k1det
    Successfully subscribed to node test_k1det
  • remove a note
    $ lvalert_admin -s lvalert-playground.cgca.uwm.edu --delete --node test_k1det
  • check current subscriptions
    $ lvalert_admin -s lvalert-playground.cgca.uwm.edu --subscriptions
  • unsubscribe
    • This works only a node which you created.
      $ lvalert_admin --username hirotaka.yuzurihara -s lvalert-playground.cgca.uwm.edu --node "tagoshi-testnode"

Usage of lvalert_listen and lvalert_send

  • launch the lvalert_listern
    • this should run in the background
    % lvalert_listen -s lvalert-playground.cgca.uwm.edu -c /users/yuzu/work/lvalert/setting/my_l
    isten.ini -r listener1 &
  • prepare the dummy alert
    • the real alert will be sent as JSON format. (But, I don't know the actual keys.)
    $ cat test1.txt
    {"uid": "G12345", "alert_type": "new", "far": 1e-8, "gps_time": 1301640384}
    $ cat test2.txt
    {"uid": "G12345", "alert_type": "new", "far": 1e-8}
  • prepare configuration file
    • when we got the alert, the following shell script will run. (Note that this shell script can't use option.)
    • the details of shell script at /users/yuzu/work/lvalert in the Kamioka workstation.

    • the details of configuration files at /users/yuzu/work/lvalert/setting in the Kamioka workstation.

    $ cat my_listen.ini
    executable = ./run_test_k1det.sh
  • send the test alert
    • Although test1.txt has gps_time, test2.txt has no gps_time.
    $ lvalert_send --username hirotaka.yuzurihara -s lvalert-playground.cgca.uwm.edu -n test_k1det --file test1.txt
    $ lvalert_send --username hirotaka.yuzurihara -s lvalert-playground.cgca.uwm.edu -n test_k1det --file test2.txt
