Probe logos

One SVG per probe page, named after the page. They are served from here rather than hot-linked, and that is the point of the directory.

Why they live here

These marks used to be fetched from a public icon CDN at render time. Ten of them stopped resolving without warning, which is what a brand withdrawing its permission from an icon set looks like, and the pages went out with an empty space where a logo belongs. Nothing in the build noticed, because nothing in the build was looking.

Serving them ourselves removes that dependency, and three others with it: the reader's browser no longer calls a third party while reading our documentation, the site builds without network access, and a rate limit on someone else's service cannot blank a page.

What they are

Marks of the vendors whose software or hardware each probe reads, reproduced to identify that system and for no other purpose. They remain the property of their respective owners, and their presence here implies no partnership, endorsement or certification. Sources are icon sets that redistribute brand marks for identification: Simple Icons, the Iconify logos and devicon collections, and Material Design Icons for the generic ones.

Where a project or vendor publishes its own SVG (ActiveMQ, ZooKeeper, NetScaler, Varnish), that file is used in preference to an icon set. Two logos (redfish.svg, modbus.svg) exist only as official rasters; they are downscaled to 128 px high and embedded in an SVG wrapper, so the one-SVG-per-page convention holds. SOURCES.md lists the source, the owner and the origin of every logo, and names the probes that keep a generic glyph because no vector mark exists.

Two are worth knowing about. exchange_online.svg carries the Microsoft corporate mark because no Exchange product mark exists in any of those sets. swarm.svg is the Docker mark, shown on the Swarm page and on its catalogue card.

Replacing one

Drop the new file in with the same name. Keep the class on the <img> as it is: probe-page-logo-si and -wm are lightened on the dark theme while -mdi is inverted, so a wrong class makes the logo disappear for half the readers. A monochrome glyph fetched with a colour query must keep that colour baked in, since nothing recolours it here.
