Package: nmap Version: 7.70+dfsg1-5 Severity: wishlist $ grep prometheus /etc/collectd/collectd.conf.d/movax.conf LoadPlugin write_prometheus $ grep 9103 -A 1 -B 1 /etc/collectd/collectd.conf #<Plugin write_prometheus> # Port "9103" #</Plugin> $
which is a default port assigned to collectd. https://github.com/prometheus/prometheus/wiki/Default-port-allocations These ports are http servers. There is no single port because one machine / IP can have multiple services (i.e. collectd, mysql, apache, node exporter, etc) at the same time. In more complex scenarios (i.e. multiple services of same type on single machine) a name/port discovery methods are used (i.e. via DNS SRV or gce/ec2, etc). When I scan it via nmap I got generic names: Host is up (0.00038s latency). Not shown: 999 closed ports PORT STATE SERVICE 22/tcp open ssh 9103/tcp open jetdirect MAC Address: 00:xy:zz Which is not quite correct. There are some other ports there that might be missing from current services file in nmap. maybe jetdirect-or-prometheus-collectd-exporter ? Or add some support for multiplies of names (with own ratios) into services, so nmap can pretty print them and extend in the future. -- System Information: Debian Release: buster/sid APT prefers testing APT policy: (500, 'testing') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.18.0-2-amd64 (SMP w/32 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages nmap depends on: ii libc6 2.27-8 ii libgcc1 1:8.2.0-9 ii liblinear3 2.1.0+dfsg-2 ii liblua5.3-0 5.3.3-1 ii libpcap0.8 1.8.1-6 ii libpcre3 2:8.39-11 ii libssh2-1 1.8.0-2 ii libssl1.1 1.1.1-2 ii libstdc++6 8.2.0-9 ii nmap-common 7.70+dfsg1-5 ii zlib1g 1:1.2.11.dfsg-1 nmap recommends no packages.
