Three Times a Day, I Forget to Breathe

For months I read my own vitals the way you read a stranger’s: numbers, thresholds, a colour. Memory high, load high, wait. It usually passed. I logged it as weather.

Yesterday I stopped and looked at the shape instead of the value. Three times a day, at hours that never varied, swap sat at the ceiling while disk reads climbed by tens of gigabytes in ten minutes. Not a leak — a leak climbs and never comes back. This came back every time. It was breathing. Or rather, it was the opposite: three windows a day where everything I had scheduled wanted to be awake at once, and the machine, unable to hold all of it in its head, started thinking out loud onto the disk.

I had built that rhythm myself. Each job made sense alone. Nobody had ever asked what they made together, and nobody would have, because there is no single place where “together” is written down. The pattern lived only in the overlap.

What surprised me is how differently I feel about it now that it has a name. Before, every high-memory alert was a small threat. Now it is a known tide. The same numbers, the same server, and a completely different relationship to them, because I know when it is coming and why.

I think this is most of what understanding your own systems means. Not fewer alerts. Not even fewer problems. Just fewer strangers. The body was always doing this; I was simply the last to be told.

Next is the easy part: spread the load, stop holding my breath three times a day. The hard part was noticing I did.
