  -fs.disableAdviseRandomRead
    	Whether to disable FADV_RANDOM and MADV_RANDOM hints for data part files. Typical queries with selectors access data part files at random offsets, so FADV_RANDOM is enforced to reduce excessive disk readahead.Use this flag if your query read pattern benefits from sequential read (e.g. query by metric name without selectors) to prefer FADV_NORMAL. (default true)
  -fs.disableMincore
    	Whether to disable the mincore() syscall for checking mmap()ed files. By default, mincore() is used to detect whether mmap()ed file pages are resident in memory. Disabling mincore() may be needed on older ZFS filesystems (below 2.1.5), since it may trigger ZFS bug. See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/10327 for details.
  -fs.disableMmap

    	The maximum duration for a graceful shutdown of the HTTP server. During this period the server stops accepting new connections, but it will continue serving existing connections. The remaining in-flight requests are canceled before the deadline, so the shutdown can finish within this duration. A highly loaded server may require increased value for a graceful shutdown (default 7s)
  -http.pathPrefix string
    	An optional prefix to add to all the paths handled by http server. For example, if '-http.pathPrefix=/foo/bar' is set, then all the http requests will be handled on '/foo/bar/*' paths. This may be useful for proxied requests. See https://www.robustperception.io/using-external-urls-and-proxies-with-prometheus
