Monitorování distribuce

Po nastavení první distribuce budete nejspíš chtít sledovat, zda funguje správně. Můžete to dělat několika způsoby.

Kontrola stavu v portálu integrací​

Aktuální stav distribuce zjistíte v portálu integrací, kde ověříte, že je distribuce zapnutá a správně nakonfigurovaná.

Po kliknutí na odkaz View & Edit uvidíte podrobnosti, jako je doba provozu (uptime) a statistiky za posledních 24 hodin. Zobrazí se i malý graf s rychlým přehledem, kolik zpráv touto distribucí za tu dobu prošlo.

Monitorování stavu přes Prometheus / OpenTelemetry​

Pokud chcete pokročilejší monitorování včetně historických dat a upozornění, můžete napojit Prometheus, který bude z našeho systému sbírat metriky. Tato funkce je dostupná všem uživatelům portálu integrací a poskytuje podrobná data o každé běžící integraci.

K vizualizaci dat doporučujeme Grafanu.

Získání URL s metrikami​

  1. Přihlaste se do portálu integrací svým účtem Dronetag, nebo si vytvořte nový.
  2. Najděte cíl distribuce, který vás zajímá, a klikněte na View & Edit.
  3. Klikněte na tlačítko Get Prometheus Metrics.
  4. Zobrazí se metriky ve formátu Prometheus/OpenMetrics.
  5. Tuto URL pravidelně stahujte nástrojem, který vám vyhovuje (podrobnosti v další sekci).

URL vypadá takto:

https://relay.dronetag.app/metrics/[[your_distribution_id]]

Poznamenejte si ID své distribuce.

Sběr metrik pomocí Promethea​

Prometheus je open-source monitorovací systém, který umí náš export metrik sbírat (scrape). Více informací a návod k instalaci najdete v oficiální dokumentaci Promethea.

Doporučená konfigurace, se kterou můžete začít naše metriky sbírat:

prometheus.yml
global:
scrape_interval: 10s
scrape_configs:
- job_name: 'dronetag_distribution_metrics'
scrape_interval: 10s
metrics_path: '/metrics/[[your_distribution_id]]'
static_configs:
- targets: ['relay.dronetag.app']

Tato konfigurace sbírá metriky každých 10 sekund z URL https://relay.dronetag.app/metrics/[[your_distribution_id]].

Dostupné metriky​

NázevPopis
relay_messages_read_totalCelkový počet zpráv přečtených na vstupu
relay_messages_distributed_totalCelkový počet distribuovaných zpráv. Může být nižší než na vstupu kvůli filtrům nebo neúspěšnému doručení.
relay_message_conversion_secondsPrůměrná doba převodu zprávy do zvoleného výstupního formátu (v sekundách)
relay_message_distribution_secondsPrůměrná doba doručení zprávy do vašeho cíle (v sekundách), z velké části odpovídá latenci serveru.

Vizualizace dat v Grafaně​

Grafana je open-source nástroj pro monitorování a analýzu dat, který umí Prometheus používat jako zdroj dat.

Jak Grafanu nainstalovat a nastavit v ní Prometheus jako zdroj dat, popisuje návod 'Get started with Grafana and Prometheus'.

Ukázkový dashboard pro Grafanu​

Připravili jsme jednoduchý ukázkový dashboard pro Grafanu. Soubor JSON můžete importovat do své instance Grafany a upravit podle svých potřeb.
