<div dir="ltr">The xymond process allocates 4k for a hostname when it reads them in from hosts.cfg.
<div><br>
<div>However, I suspect there will be other limits outside of xymond. For example, Xymon clients will be limited by their OS constraint on nodename, POSIX has a limit of 64 bytes, and the DNS also has things to say about both "A" record label limits (255)
and hostname limits (63).</div>
<div><br>
</div>
<div>The shell under which parts of Xymon run, will be OS-dependent, and might have limits on variable name lengths and filename lengths (which might limit the length of RRD file dirnames, for instance) and command-line arguments.</div>
</div>
<div><br>
</div>
<div>Also, other Xymon processes might have internal limits on the hostname length they can use, and I haven't looked any further than the xymond source code.</div>

What is the maximum allowed hostname length (excluding FQDN) in Xymon?<br>
