"Elf-Disclosure" for October 2023

Most apps consume almost no CPU while idle - the larger consumers are streamers doing transcoding, and download clients doing download/unpack operations.

Average CPU utilization increased roughly 30% from last month.

Last month (Sep 2023)'s for comparison:

This graph represents memory usage across the entire cluster. By far the largest consumers of RAM is rook-ceph. Like CPU utilization, there appears to be no month-on-month growth this month, but this data was recorded after deprovisioned accounts were pruned, so it's likely that actual used RAM has increased.

I'm not sure these stats are accurate, they've likely overly high because pods on the host network (like metallb, ceph, etc) will end up counting all traffic on each host, rather than the pod itself. However, the graph still gives a good indication of network usage compared to the previous month.

The network graphs indicate a 3-4 x increase in network usage, which is consistent with the much higher traffic graphs for October, compared to September.

Last month (Sep 2023)'s for comparison:

These are the traffic stats for egress from Hetzner. They exclude any traffic to/from Hetzner Storageboxes.

Network traffic increased 100% from the previous period, although it's notable that the large spike from Oct 15 to Oct 25^th was the likely cause, rather than a steady-state increase.

Last month (Sep 2023)'s for comparison:

Ceph provides our own storage ("[ElfStorage][elfstorage]"), typically used for long-term slow storage and seeding. While the read/write IOPS and throughput gauges below are useless for trending (they're just a single point in time, I'm working on adding better metrics), the capacity graph indicates that we've consumed 100% more capacity compared to the previous month.
