PromPlot

Plot Prometheus metrics in CLI/GUI

• Realtime 2D/3D plotting, in CLI and GUI
• Load Grafana dashboards locally from dashboard JSON
• Interactive GUI allows for easy filtering of data for better visualization

Demo

Grafana dashboard loaded via JSON model

Realtime CLI Plotting

Getting started

Making this application installable via krew is in the roadmap and will hopefully be the preferred method of installation in the future.

Quick Start

1. julia (start REPL)
2. ] activate .
3. ] instantiate
4. exit()
5. julia --project=. PromPlot.jl --promql "idelta((sum by (method, path) (kubelet_http_requests_duration_seconds_sum))[24h:])" --url "http://prometheus.my-cluster.k8s.internal:9090"
6. Replace the --url argument with your Prometheus server

To run a Grafana dashboard

1. julia --project=. PromPlot.jl --dashboard="./dashboards/example.json" --url "http://prometheus.my-cluster.k8s.internal:9090"

Available options:

usage: PromPlot.jl [--promql PROMQL] [--gui GUI] [--tui TUI]
                   [--limit LIMIT] [--url URL] [--is3d IS3D]
                   [--start START] [--end END] [--step STEP]
                   [--realtime REALTIME]
                   [--realtime-update REALTIME_UPDATE]
                   [--realtime-range REALTIME_RANGE] [-h]

optional arguments:
  --promql PROMQL       Prometheus PromQL Query (required)
  --gui GUI             Plot in GUI - Required for 3D Mode (type: Bool, default: false)
  --tui TUI             Plot in CLI/TUI (type: Bool, default: true)
  --limit LIMIT         Maximum number of series to plot (type: Int64, default: 25)
  --url URL             Prometheus URL (default: "http://localhost:9090")
  --is3d IS3D           Start in 3D Plotting Mode (default: false)
  --start START         Query Start Date (default = now(UTC) - 2h)
  --end END             Query End Date (default = now(UTC))
  --step STEP           Query Resolution (default: "1m")
  --realtime REALTIME   Enable realtime updates (type: Bool, default: true)
  --realtime-update     Realtime update interval (default: "5s")
  --realtime-range      Realtime update range (default: "1h")
  -h, --help            show this help message and exit
