Hi I have been working on a project to off load the Cassandra database over to a dedicated database server.
Has any one come across any testing tools to help test and evaluate if the database servers and connectivity are fit for purpose?
Only asking as running DMA's in a virtual environment has raised concerns over compute and connectivity so would like to test before going live with them.
Hi Richard,
I would typically use Wireshark to trace over a period the specific communication between a DataMiner Agent and it's local database. This should give you a baseline reference on how much bandwidth this communication is currently consuming.
In most cases we know that a stable low latency (sub 30ms as latency has a impact on the accessible bandwidth), Gigabit (1 Gbps) network connection between your DataMiner node and the local database node will suffice. It's only in exceptional cases (very large datasets per DataMiner agent) that we need to deviate from these default minimum specs.
This is also explained a bit in our minimum system requirements article on our documentation site.
Hope this helps!
Thanks for that I will give that a try, wasn’t sure if there was some scripts or software we can throw at it for testing throughput. For read – write ops
