I made a monitoring page for this: https://trusted-seemly-ceres.glitch.me/
You’ll see boxes representing the latency over time. Most recent measurements are on top. Occasionally the latencies are extremely high, so it’s plotted on a log scale.
This tests the latency on the projects drive with this command:
dd if=/dev/urandom of=.data/scratch.dat bs=32 count=1 oflag=sync
This makes a small write and waits for it to complete. The monitor runs this periodically and times how long this operation takes.
I’m not running this as an always-on project. I only run it when I’m using Glitch. Different runs are separated by the word “gap.”
@glitch_support, could you please add a projects disk latency monitor to status.glitch.com
