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
  [test_k1det]
  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
