ESXi Commands

Command	Action
`/etc/init.d/dcism-netmon-watchdog status`	check status of iSM
`esxtop`	"top" command for ESXi - press `n` to get networking information Press `p` (for power) then `f` (for fields) and then `f` for 'APERF%'. Shows current clock as a % of base clock if > 100%, core is boosted
`esxcfg-vmknic -l`	List vmkernel interfaces
`tcpdump-uw -i vmk{X} -s 9014 -B 9 -w /var/tmp/vmk{X}.pcap`	Legacy, see `pktcap-uw` below Create a pcap file with the following properties: `-i vmk{X}` Capture packets on vmkernel interface 'X' `-s 9014` Capture packets with jumbo frames (use `-s 1514` for standard frames) `-B 9` tcmpdump-uw by default only permits maximum of 8138 bytes. This allows capture up to 9014 bytes `-w /var/tmp/vmk{X}.pcap` What file and path to capture to - be careful not to fill the root drive
`pktcap-uw --uplink vmnic0 --dir 2 -o /tmp/lengtherror.pcap`	The pktcap-uw tool is an enhanced packet capture and analysis tool that can be used in place of the legacy tcpdump-uw tool. The pktcap-uw tool is included by default in ESXi 5.5 and later versions. This article provides information on using the pktcap-uw tool for packet capture and analysis. NOTE: pktcap defaults to inbound traffic only. 2. In vSphere 6.5 and earlier, specify the direction of traffic using --dir 0 for inbound and --dir 1 for outbound. You can’t specify traffic going both ways at the same time. However, in Sphere 6.7 and later, you can specify the direction of traffic using --dir 0 for inbound, --dir 1 for outbound, or --dir 2 for both. 3. Two (or more) separate traces can be run in parallel but need to be merged later in wireshark.
`esxcli network nic stats get -n vmnic0`	Get NIC stats for vmnic0
`_esxcli system wbem set –e true` `/etc/init.d/sfcbd-watchdog start_`	Ensure that host name is pushed to iDRAC
`esxcfg-vmknic -l`	Check NIC config (including MTU). This can also be viewed in SupportBundle/commands/esxcfg-vmknic_-l.txt
`esxcfd-vswitch -l`	Check vSwitch config (including MTU). This can also be viewed in SupportBundle/commands/esxcfg-vswitch_-l.txt
`/sbin/esxcli hardware platform get`	Gather hardware info, including service tag
