feat(metrics): delete influxdb storage for metrics

[317787106]

What does this PR do?

Removes InfluxDB as a metrics storage backend, along with all related configuration, dependencies, and code. Prometheus remains as the sole monitoring interface.

Closes tronprotocol#6665.

Why are these changes required?

java-tron currently maintains two parallel monitoring systems: Prometheus (org.tron.common.prometheus) and MetricsUtil + InfluxDB (org.tron.core.metrics.MetricsUtil). Keeping both creates fragmented metric definitions, duplicated maintenance, and operational overhead. InfluxDB support has the following specific drawbacks:

1. Fragmented metrics: Two systems produce inconsistent metric definitions with different granularity and labelling, increasing cognitive burden for developers and operators.
2. Incomplete coverage: MetricsUtil lacks dimensions such as per-peer, per-API, chain sync, DB, and JVM metrics that Prometheus already covers.
3. Operational complexity: InfluxDB requires a separate deployment, has low community adoption compared to the Prometheus/Grafana ecosystem, and has no mature dashboards or alerting rules for java-tron.
4. Stability risk: InfluxDB write failures could affect node stability; removing the dependency eliminates this external coupling entirely.

Prometheus, combined with tron-docker, provides a production-ready monitoring solution that supersedes InfluxDB for all known use cases.

Changes:

• framework/build.gradle: Removed com.github.davidb:metrics-influxdb:0.8.2 dependency.
• MetricsUtil: Deleted the init() method and all InfluxDB reporter logic (InfluxdbReporter, InfluxdbProtocols).
• ApplicationImpl: Removed MetricsUtil.init() call from startup().
• CommonParameter: Removed metricsStorageEnable, influxDbIp, influxDbPort, influxDbDatabase, and metricsReportInterval fields.
• Args: Removed initRocksDbBackupProperty-style parsing of all METRICS_INFLUXDB_* and METRICS_STORAGE_ENABLE config keys.
• ConfigKey: Removed METRICS_STORAGE_ENABLE, METRICS_INFLUXDB_IP, METRICS_INFLUXDB_PORT, METRICS_INFLUXDB_DATABASE, METRICS_REPORT_INTERVAL constants.
• config.conf: Removed the storageEnable and influxdb { ... } block from node.metrics.
• ParameterTest: Removed assertions for the deleted InfluxDB parameter fields.

Configuration change: The following config block is no longer read and should be removed from node config files:

node.metrics {
  storageEnable = false
  influxdb {
    ip = ""
    port = 8086
    database = ""
    metricsReportInterval = 10
  }
}

Follow up

Operators currently using InfluxDB for metrics should migrate to Prometheus. The tron-docker metric_monitor provides a ready-to-use Prometheus + Grafana setup.

Extra details

The /wallet/monitor/getstatsinfo HTTP endpoint remains available as an auxiliary interface (served by MetricsUtil counters/meters/histograms via dropwizard metrics-core), but it is no longer the recommended primary monitoring path.

📝 Walkthrough

Walkthrough

Removed InfluxDB/metrics storage integration: config keys, CommonParameter fields, reporter initialization and dependency were deleted; Prometheus-related metrics remain unchanged.

Changes

Cohort / File(s)	Summary
Parameter Definitions common/src/main/java/org/tron/common/parameter/CommonParameter.java	Deleted InfluxDB/metrics storage fields (metricsStorageEnable, influxDbIp, influxDbPort, influxDbDatabase, metricsReportInterval) and their accessors.
Config Keys & Loading framework/src/main/java/org/tron/core/config/args/ConfigKey.java, framework/src/main/java/org/tron/core/config/args/Args.java	Removed InfluxDB-related ConfigKey constants and removed assignments that loaded those InfluxDB/metrics storage values from config.
Metrics Utility & Startup framework/src/main/java/org/tron/core/metrics/MetricsUtil.java, framework/src/main/java/org/tron/common/application/ApplicationImpl.java	Removed MetricsUtil.init() and all InfluxDB reporter setup; removed call to initialize metrics reporter from application startup.
Build & Defaults framework/build.gradle, framework/src/main/resources/config.conf	Removed metrics-influxdb dependency and deleted the node.metrics.storageEnable and node.metrics.influxdb { ... } configuration block.
Tests framework/src/test/java/org/tron/common/ParameterTest.java	Removed assertions and setters validating the removed InfluxDB/metrics storage fields; remaining tests for other metrics fields unchanged.

Poem

🐰 I hopped through code with nimble feet,

Cleared the Influx weeds from every sheet,
Prometheus stays in morning light,
The code feels lighter — hop, delight! 🥕
