I'm trying to use the Percona Apache Monitoring [Cacti] Template for Memcached.
They do indeed warn that you can't use the openbsd version of the package and provide a solution for Ubuntu/Debian users, i.e.:
You need nc on the server. Some versions of nc accept different command-line options. You can change the options used by configuring the PHP script. If you don’t want to do this for some reason, then you can install a version of nc that conforms to the expectations coded in the script’s default configuration instead. On Debian/Ubuntu, netcat-openbsd does not work, so you need the netcat-traditional package, and you need to switch to /bin/nc.traditional...
Since the RHEL 6.x version indeed comes from openbsd (confirmed by
rpm -qi nc) how does one go about getting this installed on RHEL/CentOS?
Anyone else running these Percona templates on RHEL/CentOS? What did you do?
alien the Debian package?
Update 1: FWIW, I tried to use GNU netcat by compiling it from source but it doesn't seem to have the exact options required by the Cacti template either (i.e. there is no analogy for -C or -q1 so it seems)
Update 2: I alien[ed] the netcat-traditional_1.10-38_amd64.deb package to make a .tgz and it does produce a binary "nc.traditional" and that version has the -q option but no -C
Update 3: I alied[ed] netcat-openbsd_1.89-3ubuntu2_amd64.deb as suggested by cjc and although it provides the -C and -q options it does not appear to work with the template. I also removed the -q1 option from the nc_cmd as suggested by quanta. Still doesn't graph or produce output from the commandline.
Update 4: I built the source RPM as suggested by dmourati and left out the -q1 as suggested by quanta and still it doesn't graph or produce output from the commandline. Maybe the source RPM solution and/or not passing -q1 works on RHEL 5.x, I dunno. At this point I admit defeat.
