Hello! I’ve already asked this in the r/unraid sub but didn’t get a response, so I’m trying my luck here.
I’ve noticed some I/O spikes on my SSD, and want to figure out which Docker container is causing that. While `docker stats` shows Block I/O, it’s constantly at 0 for me, no matter where and what kind of data is written or read.
I have also tried csysdig, which requires a kernel module, which isn’t in the kernel Unraid uses. Another tool that was looked at is bcc-tools, but that needs to be run bare-metal.
My objective is to track down the I/O metrics for each disk for each container, but more specifically, I want to measure how much each container is reading from or writing to a particular drive, in this case, my SSD. Eventually, I want to store those metrics in InfluxDB to display the reads/writes in Grafana. I’m already using the telegraf docker plugin, but that doesn’t report the block I/O.
Appreciate any insight help you can offer!
