xmtopas is a daemon which is expected to run on the LPAR from where a remote consumer can fetch performance data. e.g. topas -C is a consumer which fetches data from all LPARs that are in the same CEC as the LPAR where topas -C is running.
topas -C contacts xmtopas on each of the LPARs that run on the same CEC via a Rsi (Remote Statistics Interface) connection, and once the connection is established, xmtopas keeps regularly sending performance metrics about its LPAR asynchronously to the remote querying (topas -C) LPAR.
So, if you dont have xmtopas running, performance data from that LPAR can not be relayed to any other remote LPAR and that LPAR will not be seen in the topas -C output.
Similar to topas -C there could be other consumers of xmtopas such as filtd, ITM and so on. All of these will not get the required data from the remote LPAR if xmtopas does not run on the remote LPAR. As long as there is no remote performance data collection, it is safe to comment out xmtopas in inetd.conf.
