In process_signals in the v_monitor table, i'd like to know what the signal_number means.
In particular, signal 10, but also a lookup for the numbers.
thanks!,

Re: SIGNAL_NUMBER
I'm guessing that v_monitor.process_signals contains linux process signals. You can find more documentation on those here:
http://www.kernel.org/doc/man-pages/onl ... nal.7.html
According to the linux documentation, a signal of 10 corresponds to "User Defined." I'm sorry, that's not very helpful.
The v_monitor.process_signals table also contains a SIGNAL_UID column which is the ProcessID of the sending process. Perhaps you could look up the corresponding Process for that ProcessID?

Re: SIGNAL_NUMBER
Vertica uses this user-defined signal during log rotation to signal the vertica process to start a new log file.
