Hello. Please, take a look at the following possibilities:
* `LogExporterSpi#setExportFilter` method which allows to set filter and print only specific values. * https://github.com/nizhikov/ignite-http-metrics-exporter - this exporter allows to you to export specific subset of metrics in prometheus format via HTTP. > 8 июля 2023 г., в 15:53, Greg Sylvain <greg.m.sylv...@gmail.com> написал(а): > > Hi, > > I am trying to figure out the best (most efficient, least impactful) way to > join and dynamically query a running Ignite cluster for ThreadPool metrics > and AtomicSequence Reserve size?
