using the client without a server for integration testing

[Arikael]

Hi

I need to integration test a system/application and while doing that collecting metrics about it (latency, throughput etc.).
Since we use gitlab I use the OpenMetrics format for those tests.

Now to make my live easier I don't want to write this report manually (if I don't have to), since I would only need to collect the metrics for a single test run and export it as file so gitlab can read it I thought maybe it's possible to use the client without connecting to a server.

So the client collects my metrics and exports it to a file.

Can I use the client without connecting to a server'

Hello, yes this is supported. You can generate the output using openmetrics.exposition.generate_latest and then persist that to a file if you want to specifically use the OpenMetrics format. There is also write_to_textfile which will write metrics to a file in an atomic manner suitable for use with the node_exporter textfile collector. Note that this is in the Prometheus text format, not OpenMetrics.
