VMware technical support might request several files to help resolve technical issues. The following sections describe script processes for generating and collecting some of these files.
What to read next
Set Verbose Logging You can set the verbose log file specification
Collect vSphere Log Files You can collect vSphere log files in to a single location.
Collect ESXi Log Files You can collect and package all relevant ESXi system and configuration information, a well as ESXi log files. This information can be used to analyze the problems.
ESXi Log File Locations ESXi records host activity in log files, using a syslog facility.
Configure Log Filtering on ESXi Hosts The log filtering capability lets you modify the logging policy of the syslog service that is running on an ESXi host. You can create log filters to reduce the number of repetitive entries in the ESXi logs and to denylist specific log events entirely.
Turn Off Compression for vpxd Log Files By default, vCenter Server vpxd log files are rolled up and compressed into .gz files. You can turn off this setting to leave the vpxd logs uncompressed.
ESXi VMkernel Files If the VMkernel fails, an error message appears and then the virtual machine reboots. If you specified a VMware core dump partition when you configured your virtual machine, the VMkernel also generates a core dump and error log.
