10 **trapd** runs as a single (python) process inside (or outside) the container. You can monitor it using the commands documented below.
12 *NOTE:* Familiarity with docker environments is assumed below - for example, if you stop a running instance of snmptrapd that was started using the default snmptrapd docker configuration, the container itself will exit. Similarly, if you start an instance of snmptrapd inside a container, it will not run in the background (this is a dependency/relationship between docker and the application -> if the command registered to run the service inside the container terminates, it is assumed that the application has failed and docker will terminate the container itself).
20 The **trapd** service can be started by running the command:
22 ``/opt/app/snmptrap/bin/snmptrapd.sh start``
24 Output from this command will be two-fold. First will be the textual response:
28 2018-10-16T15:14:59,461 Starting snmptrapd...
29 2018-10-16T19:15:01,966 ONAP controller not present, trying json config override via CBS_SIM_JSON env variable
30 2018-10-16T19:15:01,966 ONAP controller override specified via CBS_SIM_JSON: ../etc/snmptrapd.json

33 2018-10-16T19:15:02,048 snmptrapd.py : ONAP SNMP Trap Receiver version 1.4.0 starting

37 *NOTE:* This command will remain in the foreground for reasons explained above.
42 The **trapd** container can be monitored for status by running this command from inside the container:
44 ``/opt/app/snmptrap/bin/snmptrapd.sh status``
46 If **SNMPTRAPD** is present/running, output from this command will be:
50 2018-10-16T15:01:47,705 Status: snmptrapd running
51 ucsnmp 16109 16090 0 Oct08 ? 00:07:16 python ./snmptrapd.py
53 and the return code presented to the shell upon exit:
55 0 -> if command executed successfully and the process was found
56 1 -> if the command failed, and/or the process is not running
62 If **trapd** is not present, output from this command will be:
66 2018-10-16T15:10:47,815 PID file /opt/app/snmptrap/tmp/snmptrapd.py.pid does not exist or not readable - unable to check status of snmptrapd
67 2018-10-16T15:10:47,816 Diagnose further at command line as needed.
69 and the return code presented to the shell upon exit:
79 **trapd** can be stopped by running the command:
81 ``/opt/app/snmptrap/bin/snmptrapd.sh stop``
83 Output from this command will be two-fold. First will be the textual response:
87 2018-10-16T15:10:07,808 Stopping snmptrapd PID 16109...
88 2018-10-16T15:10:07,810 Stopped
90 Second will be the return code presented to the shell upon exit:
92 0 - if command executed successfully
93 1 - if the request to stop failed
