Thread-topic: [Xen-tools] about XenMon



Not sure what you mean by Try recompiling it or something. Maybe re-install windows


I am running RHEL xenunstable version (latest one).

Neither xenmon nor xenbaked work


This was all freshly compiled on a new system

Since setsize printed "current tbuf size: 0x1000" that means that the trace buffers have already been allocated, and the size is 1 page (kinda small). You can't re-allocate the trace buffers except by rebooting.

As for tbctl core dumping, that can't happen. ;) Try recompiling it or something. Maybe re-install windows. Or maybe update to a newer xen version, where tbctl doesn't exist anymore. Or maybe you already are running a recent xen, in which case your tbctl was built on an older installation. Anyway, you don't need tbctl anymore since xenbaked enables/disables tracing automatically for you.
