We are pleased to announce the release of DBmarlin 5.1, the first release of 2025. This version adds a new database parameter comparison report, the ability to use your own LLM and other improvements.

Parameter Comparison

You may be aware, that DBmarlin already captures database parameters that have changed and shows them as a change event in the Event history screen and on the Activity charts so you can see if they caused a change in performance. In v5.1, we added a new Parameters screen, where you can see all the parameters for the selected database and their parameter values during the selected period.

In addition, we also added a Parameter Comparison report. This works like other comparison reports in that you can compare the same instance for different time ranges or different instances. With the Parameter comparison report, it highlights which parameters are different between the instances. Having different parameters between similar instances, (like instances that are part of a cluster), could be undesirable and an indicator that one of the instance’s parameters have drifted from their ideal settings.

Use your own LLM

You can now use your own LLM with DBmarlin.

It is 1 year since we added our DBmarlin AI Co-pilot which uses OpenAI’s GPT models to assist in database and SQL tuning. In that year, Gen-AI has seen much growth and improvement and a proliferation of different Large Language Models (LLMs) from commercial vendors and open source. Rather than building custom integrations for the many options (Microsoft Co-pilot, DeepSeek, Google Gemini, Meta LLaMA, Anthropic Claude, Alibaba Qwen, Mistral Mixtral, IBM Watson Granite, Perplexity etc) we decided to offer a ‘Copy prompt’ button so you could take the prompt normally used by DBmarlin Co-pilot and instead paste it into any LLM of your choice. We have tested with several of the options mentioned above and many of them give results as good as the OpenAI results from gpt-4o.

Other notable improvements

The Settings screen for Licences now gives a breakdown of licence usage by database type and shows how many instances are defined, how many are monitored and how many licence units they are consuming. In most cases 1 licence = 1 instance but in certain cases like CockroachDB 1 licence = 1 node.

The info icon at the top of the Host Dashboard now shows host metadata such as hostname, OS name and version.
