To run the Xentop utility open an SSH console with the XenServer host or go to the Console tab in XenCenter.
Run the xentop command in the console. The console displays information about this server in a table.
Available Parameters
You can use the following parameters to configure the output for the xentop command:
- –delay=SECONDS – Set the number of seconds between updates
- -n – Output the VIF network data
- -x – Output the VBD block device data
- -r – Repeat the table header before each domain
- -v – Output the vCPU data
- -i – Number of iterations (updates) to display before xentop exits
- -f – Output the full domain name instead of a truncated name
Use the -h parameter to see more available parameters for the xentop command.
Columns Description
The Xentop utility displays the following columns in the console: CPU(sec) – Prints domain CPU usage in seconds
CPU(%) – Prints cpu percentage statistic
VCPUS – Prints number of virtual CPUs
NETS – Prints number of virtual networks
MEM – Prints current memory
MAXMEM(k) – Prints maximum domain memory statistic in KB
MAXMEM(%) – Prints memory percentage statistic, ratio of current domain memory to total node memory
NETTX – Prints number of total network tx bytes statistic/1024
NETRX– Prints number of total network rx bytes statistic/1024
VBDS – Prints number of virtual block devices
VBD OO – Prints number of total VBD OO requests. This shows the number of times that the VBD has encountered an out of requests error. When that occurs, I/O requests for the VBD are delayed.
Shows number of total VBD requests statistic:
- VBD_RD number of read requests
- VBD_WR number of write requests
Possible virtual machine states:
- d – domain is dying
- s – domain shutting down
- b – blocked domain
- c – domain crashed
- p – domain paused
- r – domain is actively running on one of the CPU
