anyone faced a similar issue Unable to load PerfMon counters for host Primary\tableaudv1.rw.com\node1: The network path was not found.?

Hey @varety,

I have a couple of questions about this setup.

1. Are those 3 AWS instances in a Virtual Private Cloud (VPC)?
2. Is the computer polling TabMon data within the same domain or VPC?

Thanks,
Dan

Hello @danjrahm , the servers are currently on premise & not hosted on AWS, all the servers are hosted on the same VM cluster

Thanks

Hello @danjrahm . I am trying to setup TabMon in a machine which doesn't host Tableau server to monitor the performance of two other Tableau hosts. I am not getting any data in the postgres table setup by TabMon. This is how my config file looks like.My Tableau server version is 2019.2.2. I've followed the steps mentioned to enable the remote polling. Not sure what I am missing.

The log files says that 'Access is denied' and thus no records are written.

The user under which Tabmon is installed (bi-util-svc) is part of the 'Performance Log Users' & 'Performance Monitor Users' group on the Tableau host machine. However, the TabMon hosts has the following information for TabMon service. So, there seems to be some mismatch in the user under which TabMon is configured and the user which is being used to poll the performance metrics form remote Tableau machine. The Tabmon host is an AWS server (and also the Tableau server host) and bi-util-svc user is an admin user on the Tabmon host. Please guide me.
