Another question is scaling, i.e. how many systems you intend to interrogate concurrently, as well as what language you wrote your code in. xCAT's IPMI stack would require that you use perl, but it can run an IPMI request against arbitrarily many systems with a single process with a single filehandle.

Ipmitool is invoked via a system() call with the command line which include redirection of stdout and stderr. We have significant investment in the parsing of the output that is generated but would like to increase the efficiency of the mechanism by creating a shared library and calling an API instead of accessing an application via forking a process. > > My review of available documentation leads me to believe there isn't an API available and if we wanted to do this, we would have to modify the source ourselves. > > Is this correct? You are correct. In my opinion from a somewhat limited perusal of the ipmitool code in the past, it's going to be very hard to convert it to an API. The fetching of data and the printing of it are all mixed together, it's not split into something where an API is going to be easy to get. It's going to be a complete rewrite. You may be better of with openipmi or freeipmi. I'm the author of openipmi and I don't know much about freeipmi, but they both provide APIs. openipmi also provides python and perl interfaces. It was designed for continuously monitoring systems, and it will be much more efficient than using ipmitool. Though it will be harder to use than simple scripting. -corey > Thanks for your time, > Dick Detweiler > ------------------------------------------------------------------------------ Colocation vs. Managed Hosting A question and answer guide to determining the best fit for your organization - today and in the future. http://p.sf.net/sfu/internap-sfd2d _______________________________________________ Ipmitool-devel mailing list Ipmitool-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/ipmitool-devel
