From indexer_stats.log, the num_requests stat is "0" for all the indexes on the node. This means that indexer node did not receive the scan request.
From test logs, cbindexperf started around 2021-11-26T09:34:41

From then on, we can see continuous errors from gometa

Vikas Chaudhary , The cbindexperf command line does not contain enabling TLS for client machine. Hence, the gometa errors. 172.23.100.118 is the client machine. cbindex command line has "-use_tls -cacert ./root.pem" option but not cbindexperf. Please re-run the test with tls enabled for cbindexperf

Vikas Chaudhary , Good that you raised this bug. From the test logs, the rows throughput is "0" for the test with TLS=all enabled. This means that none of the indexes are getting scanned.
