From a24d6af2a496b97bffba6fb43093e5f312059e57 Mon Sep 17 00:00:00 2001 From: Marco Braga Date: Thu, 14 May 2026 00:35:25 -0300 Subject: [PATCH 1/6] feat: add interactive etcd metric charts with split-pane layout MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Embed etcd Prometheus metric charts inline on the etcd page using Chart.js, replacing the previous Plotly-based approach for lighter rendering (~200KB vs ~3.5MB). Layout: - Split-pane with draggable divider (70% tables / 30% charts default) - Independent scroll on each panel - v-if/v-else ensures non-etcd pages use full-width layout unchanged Chart features: - Drag-to-select time range zoom on X axis (chartjs-plugin-zoom) - Reset zoom button per chart - Expand button opens chart in fullscreen overlay with zoom support - Responsive sizing, auto-resize on panel drag Charts displayed: - etcd fsync WAL/DB duration p99 - etcd peer round trip time - etcd total leader elections - etcd request duration p99 Data source: reuses existing Plotly JSON files already generated at metrics/ directory during report processing — no backend changes.

Changes: 1. Fix metrics processor to export all charts (NaN handling): - Added NaN/Inf filtering in processMetricV2 to prevent JSON marshalling errors - Previously, API and etcd request duration charts failed with 'unsupported value: NaN' - Now all 6 etcd/API charts are successfully exported to index.json 2. Add missing charts to web UI etcd tab: - Added chart-5: Kube API request p99 (HTTP verb breakdown) - Chart-4 (etcd request duration p99) was already defined - Web UI now displays all 6 etcd/API performance charts 3. Remove legacy metrics pages (pre-1.0 deprecation): - Removed metrics.html generation (echarts-based standalone page) - Removed index.html generation (Plotly-based standalone page) - Removed index.js generation (only used by index.html) - Cleaned up unused template constants and imports - Keep index.json and chart JSON files (used by web UI) Chart inventory: - etcd fsync WAL p99 - etcd fsync DB p99 - etcd peer round trip time - etcd total leader elections - etcd request duration p99 (operations: create/delete/get/list/update) - Kube API request p99 (verbs: GET/POST/PUT/PATCH/DELETE/APPLY/LIST) All charts use Chart.js with interactive features: drag-to-zoom, fullscreen expand, and split-pane layout. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 --- data/templates/report/report.html | 1 + internal/openshift/mustgathermetrics/main.go | 19 +--- .../openshift/mustgathermetrics/plotly.go | 89 +++---------------- 3 files changed, 15 insertions(+), 94 deletions(-) diff --git a/data/templates/report/report.html b/data/templates/report/report.html index bf68ec6c..365c47ea 100644 --- a/data/templates/report/report.html +++ b/data/templates/report/report.html @@ -225,6 +225,7 @@ { id: "etcd-chart-2", path: "./metrics/query_range-etcd-peer-round-trip-time.json.gz.json", title: "etcd peer round trip" }, { id: "etcd-chart-3", path: "./metrics/query_range-etcd-total-leader-elections-day.json.gz.json", title: "etcd total leader elections" }, { id: "etcd-chart-4", path: "./metrics/query_range-etcd-request-duration-p99.json.gz.json", title: "etcd req duration p99" }, + { id: "etcd-chart-5", path: "./metrics/query_range-api-kas-request-duration-p99.json.gz.json", title: "Kube API request p99" }, ], }; }, diff --git a/internal/openshift/mustgathermetrics/main.go b/internal/openshift/mustgathermetrics/main.go index 7d321bbf..af914ed5 100644 --- a/internal/openshift/mustgathermetrics/main.go +++ b/internal/openshift/mustgathermetrics/main.go @@ -158,8 +158,6 @@ func (mg *MustGatherMetrics) read(buf *bytes.Buffer) (*tar.Reader, error) { func (mg *MustGatherMetrics) extract(tarball *tar.Reader) error { keepReading := true - metricsPage := newMetricsPage() - reportPath := mg.ReportPath + mg.ReportChartFile // Walk through files in tarball. for keepReading { @@ -170,20 +168,15 @@ func (mg *MustGatherMetrics) extract(tarball *tar.Reader) error { // no more files case err == io.EOF: - err := SaveMetricsPageReport(metricsPage, reportPath) - if err != nil { - log.Errorf("error saving metrics to: %s\n", reportPath) - return err - } - // Ploty Page - log.Debugf("Generating Charts with Plotly\n") + // Generate index.json and individual chart JSON files for web UI + log.Debugf("Generating chart JSON files for web UI\n") err = mg.page.RenderPage() if err != nil { - log.Errorf("error rendering page: %v\n", err) + log.Errorf("error rendering chart data: %v\n", err) return err } - log.Debugf("metrics saved at: %s\n", reportPath) + log.Debugf("Chart data saved to %s\n", mg.ReportPath) return nil // return on error @@ -231,10 +224,6 @@ func (mg *MustGatherMetrics) extract(tarball *tar.Reader) error { continue } - // charts with - for _, line := range chart.NewCharts() { - metricsPage.AddCharts(line) - } log.Debugf("Metrics/Extractor/Processing/Done %v", header.Name) } diff --git a/internal/openshift/mustgathermetrics/plotly.go b/internal/openshift/mustgathermetrics/plotly.go index 627e7375..5db92932 100644 --- a/internal/openshift/mustgathermetrics/plotly.go +++ b/internal/openshift/mustgathermetrics/plotly.go @@ -1,14 +1,11 @@ package mustgathermetrics import ( - "bytes" "encoding/json" "fmt" "math" "os" - "sort" "strconv" - "text/template" "time" log "github.com/sirupsen/logrus" @@ -21,37 +18,6 @@ type ChartPagePlotly struct { UriPath string } -const indexHTML = ` - - - OPCT Charts - - - - - -

Removed Plotly format conversion (was: Prometheus → Plotly → Chart.js) - Now: Prometheus JSON → Chart.js directly - Chart.js consumes Prometheus query_range API responses natively - Eliminated 150 lines of format transformation code 2. Deleted obsolete files (dead code from metrics.html removal): - charts.go (199 lines) - 100% unused echarts integration - plotly.go (178 lines) - Plotly format conversion, now direct Prometheus - Consolidated everything into main.go (270 lines, down from 609) 3. Externalized chart configuration: - Created charts-config.json with chart metadata - Embedded via go:embed for zero-config deployment - Easy to add new charts without code changes **Code Reduction:** - Before: 609 lines across 3 files - After: 270 lines in 1 file + 30 lines config - Savings: 58% code reduction (-356 lines) **Functional Changes:** 1. Simplified API: - NewMustGatherMetrics(reportPath, data) - removed unused params - Process() extracts and saves Prometheus JSON directly 2. Better NaN/Inf handling: - Filter at processing time (not per-chart) - Aggregate stats logged once (was: per-datapoint debug spam) - Example: "Filtered 12 NaN/Inf datapoints from 1850 total (0.6% invalid)" 3. Web UI updates (data/templates/report/report.html): - Parse Prometheus JSON format in renderEtcdCharts() - Extract labels from metric.metric{} object - Convert Unix timestamps to JS Date objects - Removed unused parseMetricTimestamp() method **Dependency Cleanup:** Removed unused dependencies: - github.com/go-echarts/go-echarts/v2 (echarts charts) - k8s.io/utils/ptr (pointer helpers for echarts) **File Changes:** Modified: - internal/openshift/mustgathermetrics/main.go - Complete rewrite - data/templates/report/report.html - Prometheus JSON parser - internal/opct/summary/result.go - Updated caller - pkg/cmd/adm/parsemetrics.go - Updated caller and messages Added: - internal/openshift/mustgathermetrics/charts-config.json - Chart metadata Deleted: - internal/openshift/mustgathermetrics/charts.go - Dead code - internal/openshift/mustgathermetrics/plotly.go - Unnecessary conversion **Testing:** Validated with real OPCT archive: - ✅ All 6 charts generate correctly - ✅ Prometheus JSON format preserved - ✅ NaN/Inf filtering works (no JSON marshalling errors) - ✅ index.json created with correct IDs - ✅ Web UI parses Prometheus format (needs browser test) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 --- data/templates/report/report.html | 42 +- go.mod | 1 -

Standardized Y-axis units to milliseconds for all duration metrics to improve readability and cross-chart comparison. Changes: - Added metrics.html with grid layout (3-4 columns, responsive design) - Implemented click-to-expand modal for full-size chart viewing - Converted duration metrics from seconds to milliseconds - Added Y-axis labels showing units (ms/count) - Limited etcd tab to 2 core fsync charts (WAL and DB) - Added info banner in etcd tab linking to full dashboard - Renamed "Metrics" tab to "Dashboard" - Reordered tabs: OPCT → Dashboard → Tests → Events → CAMGI - Auto-generated files: index.html (redirect), metrics.html (dashboard) Dashboard Features: - Grid layout with 3-4 columns of chart widgets - Click any chart to open full-size interactive modal - All 6 charts: etcd fsync WAL/DB p99, peer round trip, leader elections, etcd request duration p99, Kube API request duration p99 - Chart.js with zoom/pan controls in both views - Responsive design for mobile/desktop Metric Improvements: - Duration metrics now show milliseconds (5 ms vs 0.005 s) - Y-axis labeled with unit (ms or count) - Consistent units across all charts for easy comparison - Applied to grid dashboard, modal, and etcd tab Files Modified: - internal/openshift/mustgathermetrics/main.go - HTML embedding and generation - data/templates/report/report.html - etcd charts ms conversion, tab reordering - internal/openshift/mustgathermetrics/metrics.html - new grid dashboard (embedded) - internal/openshift/mustgathermetrics/index.html - redirect (embedded) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 --- data/templates/report/report.html | 31 +- .../openshift/mustgathermetrics/index.html | 10 + internal/openshift/mustgathermetrics/main.go | 21 + .../openshift/mustgathermetrics/metrics.html | 397 ++++++++++++++++++ 4 files changed, 447 insertions(+), 12 deletions(-) create mode 100644 internal/openshift/mustgathermetrics/index.html create mode 100644 internal/openshift/mustgathermetrics/metrics.html diff --git a/data/templates/report/report.html b/data/templates/report/report.html index fa394f0d..053438a5 100644 --- a/data/templates/report/report.html +++ b/data/templates/report/report.html @@ -25,12 +25,11 @@
