I was trying to compile collectd on a old CentOS 6 host, and ./configure complained that rrdtool couldn’t be found; e.g.
rrdtool . . . . . . . no (rrd.h not found)
I’d intended to use rrdtool to collect instance-level metrics and then graph ’em out with CGP, so it was pretty annoying. TIL that you can use the “-ql” to list the files installed by a particular binary; e.g.
$ rpm -ql rrdtool-devel
package rrdtool-devel is not installed
I installed rrdtool-devel, and then lo and behold:
rrdtool . . . . . . . yes
