The other idea is to make fping use a popen if possible.
> who i do this?. In the codes [1]: If have to audit the code(s) and find the opportunities to use popen. You have to understand that popen in php, and other scripting languages, is not the same as popen as it is in a "C" program. You start playing around with one part of files and soon you'll find the monotonic nature of the mysql database engine, might be a bottleneck that is only resolved buy upgrading to postgresql. Lot of folks are doing this since Oracle took over mysql [2]. I've never pushed the limits of jffnms, so I cannot say this as it relates to jffnms. But, the future of opensource databases is postresql. Oracle is know as an open source killer, if you look back through their string of acquisitions. Before I move to postgresql, I'd test your installation on x86_64 hardware, with a 3.15.x linux kernel. Craig or others might be able to send you a /usr/src/linux/.config file so you can build a custom kernel tuned exclusively for linux_jffnms_mysql performance. In fact that ".config" file would be of keen interest to the wider jffnms community and maybe should be part of the jffnms website (Craig?). To begin to understand just how old (deprecated) your linux kernel is look here at your 2.6.32 kernel[3] and compare it to the current release of the linux kernel [4]. Feature and bug fixes abound; if you want those details, just read on the kernelnewbies.org website about these added features and bug fixes, for each of the dozens of versions of the linux kernel releases between your current kernel and a version of the kernel you a *should* running.

Why not put up a "Debian box" then you'd be almost as cool as my hero, Craig...... Debian is a fine distro, just not as capable as Gentoo as it is built from 100% user controlled sources. Probably a bit more than you need? ;-) hth, James ------------------------------------------------------------------------------ Want fast and easy access to all the code in your enterprise?
