I’ve only ever grepped log files. 9 years into my career now so not sure which side of the spectrum I’m on (i’m definitely on the spectrum)
I’m grepping log since the 80s/90s, still do
Here we are all on the spectrum my friend.

Good luck connecting to each of the 36 pods and grepping the file over and over again
I’m running Grafana Loki for my company now and I’ll never go back to anything else. Loki acts like grep, is blazing fast and low maintenance. If it sounds like magic it kind is.
I saw this post and genuinely thought one of my teammates wrote it.
I had to manage an ELK stack and it was a full time job when we were supposed to be focusing on other important SRE work.
Then we switched to Loki + Grafana and it’s been amazing. Loki is literally k8s wide grep by default but then has an amazing query language for filtering and transforming logs into tables or even doing Prometheus style queries on top of a log query which gives you a graph.
Managing Loki is super simple because it makes the trade off of not indexing anything other than the kubernetes labels, which are always going to be the same regardless of the app. And retention is just a breeze since all the data is stored in a bucket and not on the cluster.
Sorry for gushing about Loki but I genuinely was that rage wojak before we switched. I am so much happier now.
We do Grafana + Prometheus for most of our clients but I think that adding Loki into the mix might be necessary. The amount of clients that are missing basic events like “you’ve run out of disk space…two days ago”, is too damn high.
