# # Exercise 2: Service Health Check

# Create one or multiple FiLiP clients and check if the corresponding services
# are up and running by accessing their version information.

# The input sections are marked with 'ToDo'

# #### Steps to complete:
# 1. Set up the missing parameters in the parameter section
# 2. Create FiLiP ngsi_v2 clients for the individual services and check for
#   their version
# 3. Create a config object for the ngsi_v2 multi client (HttpClient),
#   create the multi client and again check for services' versions
