[uanog] Re: metrics collector

Hi colleagues, thanks a lot everyone, it seems the puzzle is assembling in my head. Will look into the VictoriaMetrics since it's a drop-in replacement for Prometheus while being more effective and faster. Push model required not just for generic pods/k8s metrics but for gathering internal pod's metrics as well, so native support for push messages in Victoria is a big plus. Appreciate your help :-) Have a nice day! On 6/11/24 16:54, Vadim Kurland wrote:

if this is for kubernetes, you could look into node-exporter. It deploys as daemonset and should automatically start on new nodes. Prometheus scrapes from node-exporter and gives you good visibility into node resources and follows them as they come up and go down

as for monitoring of containers and pods, look into cadvisor, it is embedded in the kubelet

All of this works with standard Prometheus pull. Prometheus guys do not recommend using push at any scale because it is expensive and complex.

Good overview:

Visualisation and alerts can be done with Grafana. There is also Prometheus alert manager.

All of this is very mature and well maintained. Do not reinvent the wheel

Привіт, а скажіть мені таку штуку, панове.

Я тут дивлюсь на Прометей та здається мені, що він не альо для dynamic scale in/out, бо заточений під data pulling, а коли поди в кубері автоскейляться, то стає різко незрозуміло, звідки пулити дату :)

Push типу є, але його зроблено збоку, через PushGateway, який  самим розробниками радиться to use in certain limited cases через низку причин - https://prometheus.io/docs/practices/pushing/

Тож питання наступне - а що ви знаєте на риночку таке, що вміє push natively та може бути зінтегрованим з притомною візуалізацією / алярмовкою?

Дякую
