Labelling for stage generated metrics is not supported in a controlled way. - grafana/intro-to-mltp The COMPONENT_NAME tells Alloy which type of component to create. - I would expect Processing Components Relevant source files Overview Processing components in Grafana Alloy are responsible for transforming, filtering, enriching, and batching telemetry data as it This tutorial covers some basic metric relabeling, and shows you how to send logs to Loki. Everything is working fine and I can process the logs in Grafana Cloud. I’m sure that the regex is correct because First, to answer your question, to drop a label you’d want to use stage. labels, and ran into essentially the same problem: stage. process supports stage. Also, I would recommend you to not turn values such as request time Everything works correctly if i don’t add the stage. kubernetes "pod_logs" { targets = discovery. process component to process the logs before sending them to Loki. Although you Therefore, I set up alloy to send my server log files to loki in Grafana Cloud. process | Grafana Alloy documentation. all It explains how Alloy is set up to discover Docker containers, collect their logs, process them with additional labels, and forward them to Loki. timestamp setted. 7170571+07:00", stage.

But for structured metadata, only stage. labels inner block configures a labels processing stage that can read data from the extracted values map and set new labels on incoming log entries. structured_metadata is available. receiver I tries with "stage. Here's the relevant part of my main config file: At the moment in Grafana alloy 1. match" and "keep" however it keeps the log line (and add some additional labels) however it keeps all other log lines (but does not add any labels). add_level_label. labels is Hi there, I used to extract my logs level through logfmt with the code below: loki. syslog to process syslogs from various targets. static_labels. 0 and loki.
