Dear Xen users,
I use munin to monitor xen servers and munin uses xentop command to gather
information:
$ xentop -b -f -i2
In rare cases the output of this command gives too high (it seems buggy)
values for CPU(sec) and CPU(%), this destroys the munin graphs.
I tested this command from cli. After 50.000 cycle of run i got 72 case of
too high value.
Example normal values:
NAME STATE CPU(sec) CPU(%) MEM(k) MEM(%) MAXMEM(k) MAXMEM(%) VCPUS NETS NETTX(k) NETRX(k) VBDS VBD_OO VBD_RD VBD_WR VBD_RSECT VBD_WSECT SSID
