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
blacklist specific log events entirely.
Log filters affect all log events that are processed by the ESXi host vmsyslogd daemon, whether they are
recorded to a log directory or to a remote syslog server.
When you create a log filter, you set a maximum number of log entries for the log messages. The logs
messages are generated by one or more specified system components and that match a specified
phrase. You must enable the log filtering capability and reload the syslog daemon to activate the log filters
on the ESXi host.
Important Setting a limit to the amount of logging information, restricts your ability to troubleshoot
potential system failures properly. If a log rotate occurs after the maximum number of log entries is
reached, you might lose all instances of a filtered message.
Procedure
1 Log in to the ESXi Shell as root.
2 In the /etc/vmware/logfilters file, add the following entry to create a log filter.
numLogs | ident | logRegexp
where:
n
numLogs sets the maximum number of log entries for the specified log messages. After reaching
this number, the specified log messages are filtered and ignored. Use 0 to filter and ignore all the
specified log messages.
n
ident specifies one or more system components to apply the filter to the log messages that these
components generate. For information about the system components that generate log
messages, see the values of the idents parameters in the syslog configuration files. The files
are located in the /etc/vmsyslog.conf.d directory. Use a comma-separated list to apply a filter
to more than one system component. Use * to apply a filter to all system components.
