Утречко! (какое, нафиг, утречко — час дня)

Что-то у меня сегодня совсем не задалось настроение. Виной тому то ли погода, то ли моя рассеяность, то ли электро-индастриал в колонках. Поэтому мне очень лень что-то сегодня искать. Извините 😞

Но вот есть статья из загашника со сравнением Prometheus, Sensu и TICK Stack

Она старая, но, может, кому будет интересно

#monitoring #prometheus #sensu
Ну суть, я думаю, вы уловили: вышел Prometheus 2.0

Из нового:
- переделали сторейдж. Обещают прирост производительности аж:
= CPU на 20%-40% меньше, чем в версии 1.8
= Место на диске: меньше на 33%-50% в сравнении с 1.8
= I/O и так, говорят, низкое былоек

- Staleness handling (видео презентации с PromCon 2017)

- Можно делать снэпшоты вот прямо всего хранилища

Changelog

Upgrade guide

Ну и, конечно же, бонус! Видосы c PromCon 2017

#monitoring #kubernetes #prometheus
​​​While I was on vacantion ​Cloud Native Computing Foundation (CNCF) announced open source monitoring toolkit, Prometheus, has graduated from its incubation status.

To graduate from an incubating status to a graduated status, the project had to adopt the CNCF code of conduct, under-go an independent security audit and disclose its governance structure which outlines how they plan to grow their community.

​​Trickster - Open Source Dashboard Accelerator for Time Series Databases

Trickster was developed internally in Comcast, and half-year ago made available open source. Written in Go, Trickster is a reverse proxy cache for the Prometheus HTTP APIv1 that considerably accelerates dashboard rendering times for any series queried from Prometheus. This is possible because of the delta proxy, step boundary normalization, and fast forward features.

More info can be found at github and this youtube intro

​​A list of awesome Prometheus alerts, divided by the nature. I.e. there are alerts for data bases, proxies and load balancers, storage, etc.

You can just copy-paste these into your monitoring code. Just keep in mind that the thresholds may be different for your particular case!
