This brief report highlights some significant commits to the [scylla-cluster-tests.git master](https://github.com/scylladb/scylla-cluster-tests) from the past week, covering commits in the d311c6c1…cf79ff75 range.

During this period, 24 non-merge commits were made by 5 software engineers in test and 1 software engineer, with some notable changes:

We have resolved an issue regarding the restoration of monitoring when ports were occupied. Now, [in such cases, a random port is chosen.](https://github.com/scylladb/scylla-cluster-tests/commit/67d5c7b8536aab8d6241b4ba503b6ec456952f64)

The [upgrade of scylla-bench](https://github.com/scylladb/scylla-cluster-tests/commit/318e4beb6c9bacb211d582592abacd85d59dc516) with gocql support for tablets was [reverted](https://github.com/scylladb/scylla-cluster-tests/commit/cf79ff757eb5b3431035e688ede85c4ea1dae417) due to a [scylla-bench issue](https://github.com/scylladb/scylla-bench/issues/134).

Support for `RackAwareRoundRobinPolicy`, introduced in [scylladb/java-driver#227](https://github.com/scylladb/java-driver/pull/227), [was added to the cassandra-stress thread](https://github.com/scylladb/scylla-cluster-tests/commit/8bf92af3e17695ace91db6d20b8ff5c48de6706d). This is automatically used when we set up multiple racks, allowing the loader to spread across multiple AZs. A [new test](https://github.com/scylladb/scylla-cluster-tests/commit/da811fe368f1673458d9c0f140b8e4ee7ed45c7f) was added to fully utilize this feature.

The [network interface configuration](https://github.com/scylladb/scylla-cluster-tests/commit/2c2369dd228cdef9c326007ebe1f0e2345da43b6) has been refined to better test Scylla networking with multiple NIC/IP combinations. Now, it’s easier to define which Scylla endpoint is mapped to which interface and IP.

The subject of the cloud resources usage email [has been reverted back to static](https://github.com/scylladb/scylla-cluster-tests/commit/ad5ecf16a2afcc1c1fd63fc6dddbe69ab3aafe29). Please ensure you correctly assign the “important” label when your name is listed, so you don’t overlook any lingering resources.

Metrics from the sct-runner revealed an issue with high CPU usage that could lead to a ‘Bad packet length’ problem. To combat this, [we updated the sct-runner instance](https://github.com/scylladb/scylla-cluster-tests/commit/9d383b7a3cbbcdadf5fb9c8a29be6ff6282d3e9a) and began to [trim db log lines longer than 5K](https://github.com/scylladb/scylla-cluster-tests/commit/076d89acb215908f2b1b07426f619c60c3df2229) to prevent searches and regexes from taking too much time.

Finally, the new `tablets_initial_scale_factor` scylla.yaml option [is now supported](https://github.com/scylladb/scylla-cluster-tests/commit/ec9cbf7124b1c53b80706d3bffeb22ca685fde87) and can be used in the `append_scylla_yaml` test configuration.

Stay tuned for the next issue of last week in scylla-cluster-tests.git master!
