Stop repeating the timestamp and level in runtime log lines

[yaseemarusiru]

Purpose

Fixes wso2/product-integrator#456

Each row on the Runtime Logs page shows the timestamp and level, then the log line, which starts with time=… level=… again. For BI logs, the row timestamp is also the time Fluent Bit ingested the line, not the time it was logged.

Approach

All changes are in opensearch_adapter_service.bal:

• constructLogEntry no longer puts time= and level= in LogEntry. They are already returned as TimeGenerated and LogLevel. Copy and download in the console already prefix both, so they stop repeating them too.
• TimeGenerated is now the log's own time, falling back to @timestamp. The BI Fluent Bit parser doesn't use time as its time key, so @timestamp is the ingest time for BI logs.
• The query sorts and filters on time (falling back to @timestamp for documents without it). The console pages by passing the last row's timestamp back as endTime, so the sort, the filter and the returned timestamp need to use the same field.

Tests

Tested locally with the OpenSearch observability stack, a BI runtime and an MI 4.7.0 runtime:

• Log lines no longer start with time=… level=…, for both BI and MI.
• Rows are ordered by log time for BI, MI and a project view that mixes both.
• Paging through the console's cursor logic returns rows in order with no duplicates.

📝 Summary

Updated log entries to omit timestamps and levels already shown in separate columns. Log searches now prefer time for returned timestamps, time-range filtering, and sorting, with @timestamp as a fallback when time is absent.

Walkthrough

The OpenSearch adapter sorts log searches by time when that field is present and nonempty. Time-range queries match time, or use @timestamp when time is absent. Returned timestamps prefer a nonempty time value and otherwise use @timestamp. Formatted log-entry strings no longer include time or level; they retain the other assembled fields.

Priority: ⬇️ Low

Severity of issue fixed: Low

Merge Risk: ⚪ Minimal · up to 8019b

Log lines stop repeating the timestamp and level, and searches sort and filter by the same timestamp the console shows. No outstanding issue blocks merging.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 8019b

Timestamp-based searching and paging change, while existing user access checks remain in place. No new security finding was established, but deployment-level access restrictions have not been fully verified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The normal user path remains limited to authorized runtime IDs. If a valid service-token holder can reach the adapter directly, an empty runtime list can search without runtime restriction across the selected BI, MI, or combined index families. This capability predates the PR; its deployed reachability is unresolved.

Trust Boundaries and Controls

• observed — Per-user runtime authorization is enforced upstream through storage:hasAccessToRuntime. The downstream request uses a generated service bearer token, and the adapter configures issuer, audience, and HMAC signature validation. The adapter logs resource does not use its declared API-key parameter, so that parameter is not an additional control in the inspected path.
