+Available options:
+build - locally builds simulator image from existing code
+start - starts simulator and netopeer2 containers using remote simulator image and specified model name
+compose - customize the docker-compose and configuration based on arguments
+trigger-simulator - starts sending PNF registration messages with parameters specified in config.json
+stop-simulator - stop sending PNF registration messages
+stop - stops both containers
+status - prints simulator status
+clear-logs - deletes log folder
+
+Starting simulation:
+- Setup the instance of this simulator by:
+ - ./simulator.sh compose IPGW IPSUBNET I URLVES IPPNFSIM IPFILESERVER TYPEFILESERVER PORTSFTP PORTFTPS IPFTPS IPSFTP
+ where IPGW and IPSUBNET will be used for docker network
+ where I is the integer suffix to differentiate instances
+ where URLVES is the URL of the VES collector
+ where IPPNFSIM, IPFILESERVER, IPFTPS, IPSFTP are the IP addresses for containers
+ where TYPEFILESERVER is the type of fileserver, i.e., FTPS or SFTP
+ where PORTSFTP, PORTFTPS are the SFTP and FTPS ports
+ e.g. ./simulator.sh compose 10.11.0.65 10.11.0.64 3 http://10.11.0.69:10000/eventListener/v7 10.11.0.2 10.11.0.66 ftps 2001 2002 10.11.0.67 10.11.0.68
+
+- Setup environment with "./simulator.sh start". It will download required docker images from the internet and run them on docker machine
+- To start the simulation use "./simulator.sh trigger-simulator", which will start sending PNF registration messages with parameters specified in config.json
+
+To stop simulation use "./simulator.sh stop-simulator" command. To check simulator's status use "./simulator.sh status".
+If you want to change message parameters simply edit config.json, then trigger the simulation with "./simulator.sh trigger-simulator" again
+Logs are written to logs/pnf-simulator.log.
+
+If you change the source code you have to rebuild image with "./simulator.sh build" and run "./simulator.sh start" again
