Hello everyone, first post as I am trying to build an IDS panel leveraging on-prem (no i wont pay for the cloud, ever) grafana + loki + promtail + snort3
I have all of these working BUT promtail because it just loops and chokes itself to death
VM hosted on Proxmox VE w/ 4 cpu’s and 24GB of vRAM
Version:
promtail, version 2.8.2 (branch: HEAD, revision: 9f809eda7)
build user: root@b7e9ca0bf6e0
build date: 2023-05-03T11:13:57Z
go version: go1.20.4
platform: linux/amd64
The Issue:
- Regardless if its 8GB, 64GB of RAM, as soon as the promtail service starts, the leaks/runs away until complete lockup (under 20 seconds)
What have I tried:
- Different vCPU (now on host cpu, EPYC 7551P, which has AVX2 encoding, to be safe)
- Different RAM
- Various bandwidth limits in the .yaml file (no change in end result)
Current Configs:
- Promtail .service file
