There is example code here https://sdkdocs.roku.com/display/sdkdoc/roSystemLog
which copied simply causes a crash;

Current Function:

120:                  i = msg.GetInfo()
121:                  If i.LogType = "http.error" or i.LogType = "http.connect"
122:                      If i.LogType = "http.error"
123:                          metrics.errorCount = metrics.errorCount + 1
124:                          print "http error: "; i.HttpCode; "URL: ";i.Url
125:                      End If

Obviously the 'httpIpAddrs' object needs to be initialized, but what is the point of this object, is it explained elsewhere?

It looks like they're just trying to maintain a list of ip addresses for their own logging purposes, but as you noted they have not initialized the object. You don't need that part; you can do whatever you want with the log data. Obviously, their code wasn't tested (I don't think the compiler will like CeateObject either).
