Configuring System Logging
ESXi hosts run the syslog service (vmsyslogd), which writes messages from the VMkernel and
other system components to log files and can forward messages to syslog collectors in the
network.
You can configure the amount and location of the logs. You can also create and apply log filters to
modify the logging policy of an ESXi host.
Configure Syslog on ESXi Hosts
You can use the vSphere Client, the VMware Host Client, or the esxcli system syslog
command to configure the syslog service.
For information about using the esxcli system syslog command and other ESXCLI
commands, see
Getting Started with ESXCLI
. For details how to open the ESXi firewall for the
port specified in each remote host specification, see ESXi Firewall Configuration.
Procedure
1 Browse to the host in the vSphere Client inventory.
2 Click Configure.
3 Under System, click Advanced System Settings.
4 Click Edit.
5 Filter for syslog.
6 To set up logging globally and configure various advanced settings, see ESXi Syslog Options.
7 (Optional) To overwrite the default log size and log rotation for any of the logs:
a Click the name of the log that you want to customize.
b Enter the number of rotations and the log size you want.
8 Click OK.
Results
Changes to the syslog options take effect.
Note Syslog parameter settings that you define by using the vSphere Client or VMware Host
Client are effective immediately. However, most settings you define by using ESXCLI require an
additional command to take effect. For more details, see ESXi Syslog Options.
