SysAdmin's Journey

Compiling Nagios Plugins and NRPE on Solaris 10 With Sun Studio

We have some Sun T1000’s running Solaris 10 that we are going to deploy as web servers. By compiling Apache from source using the Sun Studio compilers, you get a huge boost in performance because of the compiler’s built-in optimizations for the Niagra processor. Before deploying them, I needed to get NRPE setup, which requires that the Nagios plugins be installed. Once setup on the client side, I can point our Nagios server at the webserver and get notified of hardware issues, disk usage, load averages and what not. Installing NRPE and the plugins using gcc is a no brainer. I thought using Sun Studio wouldn’t be too much harder, but after 5 hours of banging my head against the wall, I figured out how to make them compile… To compile the two, first set your PATH variable so that it can find Sun Studio, and the Sun make binary:

export PATH

Now, the tricky part. Everything I did was failing with SSL issues. Once I fixed that, check_procs wasn’t working properly. Turns out you need to set some CFLAGS and tell configure how to run ps:

CFLAGS='-DSSL_EXPERIMENTAL -DSSL_ENGINE -xO4' ./configure --with-ps-command="/usr/bin/ps -eo 's uid pid ppid vsz rss pcpu etime comm args'" --with-ps-format='%s %d %d %d %d %d %f %s %s %n' --with-ps-cols=10 --with-ps-varlist='procstat,&;procuid,&;procpid,&;procppid,&;procvsz,&;procrss,&;procpcpu,procetime,procprog,&pos;'

Then make, su, make install as usual. Wash, rinse, and repeat for NRPE.
