I am working with a real time system written in C++. We are looking to use either boost or pantheios for logging. The system has some standard logging requirements which I’m confident can be met by either framework, but in addition we want to be capable of logging all input captured by this system. This input will be captured by multiple threads, including some threads that have real-time constraints and can not afford significant delays from inefficient logging. This should result in a high throughput of data to be logged.

I primarily want to know whether either framework can be trusted to manage such high throughput logging from multiple threads without delaying my time critical threads. In addition we may need to do some data scrubbing which would require adding some sort of hook which is capable of identifying the capture inputs which have secure data, run our data scrubbing hook, and maintain a buffer containing mappings of values that were already scrubbed.

I believe both logging platforms can do this, but it’s not clear to me with a quick glance at their API. Can anyone who has used either of these logging tools give me some feedback on how efficient they are in this context, how easy it would be to implement what I described, or their preference between the two logging frameworks? Really any information would useful.

Thanks

    I am using the Boost logging library written by Jon Torjo and this one offers to do all writing to log files from a dedicated thread, so you have no I/O delays on the thread doing the logging. This has the disadvantage thought, that when the system crashes some log statements might not be logged, as it makes use of an internal queue.

    But generally this library is performing very well, gives you a lot of different options and I think could be a good option for you, if you’re willing to sacrifice on messages.

    If that is not an option, you’ll have to do I/O from the thread needing to log, which is really not ideal on a real-time system.

    If you’re running on Windows, you know it is not a RT OS, right?
