Hello, I'm using Elastic Cloud and very pleased with it so far. However I've come with a requirement that I can't seem to find a solution for. Is someone able to point in the right direction? The application uses Mysql and H2, and all queries are being logged, however I don't want the H2 queries logged within a transaction, is it possible to permentently ignore certain types of spans somehow? Either in the Kibana view, or not sending them in the first place? `disable_instrumentations` allows me to disable jdbc, but I only want to disable a specific DB type. Thanks, Steven. ---

Hey and welcome to the forum! One option to deal with this is through ingestion - check out the [ingest node pipelines](https://www.elastic.co/guide/en/apm/server/7.7/configuring-ingest-node.html). The [drop processor](https://www.elastic.co/guide/en/elasticsearch/reference/7.7/drop-processor.html) should fulfil your needs. Another option is to exclude the H2 driver classes from instrumentation at the agent itself - try to set `classes_excluded_from_instrumentation` with the H2 driver base package (if you use as System property, the property name would be `elastic.apm.classes_excluded_from_instrumentation`). For example - `classes_excluded_from_instrumentation=org.h2.*` I hope this helps. ---

I corrected the example above, as the`classes_excluded_from_instrumentation` config needs to be set with wildcards in order to exclude packages. ---

Brilliant. That sorts it 👌 `classes_excluded_from_instrumentation` is a most useful addition. However, I can't find any mention of it in the docs? Is it something you don't normally want people to use? ---

Currently it's a hidden config, and by setting it you actually overrode the defaults, but if you don't get anything instrumented that you don't want - this is not a problem. We intend to expose it soon, it just requires a small change so it wouldn't override the defaults. Once we do that, it will be documented as well. Thanks for the feedback! ---
