grafana prometheus

Is there a way to get all the failed targets that Prometheus knows about?

发布于 2020-12-03 09:30:13

Hi i'm working on a solution that needs to know how many targets failed to be fetched. I'm currently running a node-exporter job with static configuration, so all the hosts are known from the get go. What i would like to display in Grafana is something like "2/3 hosts are up". But i can't really seem to find a metric that contains the same numbers as shown in the image.

enter image description here

All help is much appreciated, right now i'm searching for keywords in the metrics page of whatever exporter is containing metrics, if there is an easier way of finding the correct data please let me know.

count(up == 0) by (job)

should give you "1" for "node-exporter", while:

count(up) by (job)

should give you "3".

Mamba is a new state space model architecture showing promising performance on information-dense data such as language modeling, where previous subquadratic models fall short of Transformers. It is based on the line of progress on structured state space models, with an efficient hardware-aware design and implementation in the spirit of FlashAttention.
