Server state
OxPHP serves this site itself. Below are the readings of the machine that answered your request, as they stand right now. Nothing is stored: the charts start the moment you open the page.
Since the last deploy
The server keeps these counters itself, from the moment it starts. Every deploy is a restart, so the count runs from the deploy.
Right now
The memory scale is absolute: it runs from zero to the whole memory of the machine and never rescales. Requests and response time scale to their own peak.
Workers
Each worker keeps the application loaded between requests. If its PHP memory grows past 128 MB, the server replaces it with a fresh one, and its row starts counting again.
Worker mode is off, so no worker lives longer than one request and there is no table to show.
oxphp_worker_memory_bytes · oxphp_worker_uptime_seconds · oxphp_worker_requests_count · oxphp_worker_request_fibers_active
The “now” column is approximate, since the reading and the count of streams held by this page are not taken in one step.
Where the numbers come from
The counters and histograms come from the built-in internal server of OxPHP, the same /metrics endpoint you get on your own machine. Memory comes from the Linux kernel. The server runs in a gVisor sandbox with a kernel of its own, so the chart shows the memory of the whole container, from /proc/meminfo. Memory and response time include the work of this page itself. There is no CPU chart. Inside gVisor the process sees only a small part of the CPU time the platform counts (0.8% against 4.3% on production), and a number nobody can vouch for has no place here.
The deploy clock is the moment the container started, read as btime from /proc/stat. On DigitalOcean that is a deploy or a move to another machine, and a move resets it too. It is not confirmed whether the platform restarts a crashed server in the same container, where this page would say the server restarted, or in a new one, where the crash would look like a deploy. Only numbers leave the machine. Configuration, paths and addresses stay on it. The stream is plain SSE, served by a PHP worker like this page, and while it waits for the next step that worker serves everyone else.
