Monitoring JVM Metrics with Signoz in Kubernetes Cluster
TLDR Ragul had trouble monitoring JVM metrics in their Kubernetes cluster with Signoz using Helm. Srikanth advised modifying the scrape config in values.yaml and checking the `host:port/path`.

Tue, 06 Jun 2023 07:47:30 UTCThe default one from values.yaml doesn’t scrape the metrics exposed by general applications. You need to configure it with the endpoints where you applications emit metrics.

Srikanth
Tue, 06 Jun 2023 11:24:20 UTCYes, you need to add an additional scrape config in values.yaml. It would look like following. ```otelCollectorMetrics: config: receivers: # prometheus scrape config prometheus: config: scrape_configs: ... <existing_configs_here> - job_name: 'applications-metrics' scrape_interval: 10s metrics_path: <your probe endpoint> static_configs: - targets:```

Tue, 06 Jun 2023 16:59:18 UTCI added this above config in values.yaml , and upgraded helm using the command -> helm -n platform upgrade my-release signoz/signoz -f values.yaml . but still i am not getting those above mentioned metrics

Tue, 06 Jun 2023 17:01:45 UTCfor cross check in signoz clickhouse i tried with -> SELECT name FROM ( SELECT DISTINCT JSONExtractString(labels, '__name__') AS name FROM signoz_metrics.time_series_v2 ) AS tmp1 WHERE name ILIKE '%jdbc%' with this query
Ragul
