Configuration Example For Outputting Logs To A Linux Log Host - HPE FlexFabric 5700 Series Network Management And Monitoring Configuration Manual

# Device configuration messages
local4.info /var/log/Device/info.log
In this configuration, local4 is the name of the logging facility that the log host uses to
receive logs. info is the informational level. The UNIX system records the log information
that has a severity level of at least informational to the file /var/log/Device/info.log.
NOTE:
Follow these guidelines while editing the file /etc/syslog.conf:
• Comments must be on a separate line and must begin with a pound sign (#).
• No redundant spaces are allowed after the file name.
• The logging facility name and the severity level specified in the /etc/syslog.conf file must
be identical to those configured on the device by using the info-center loghost and
info-center source commands. Otherwise, the log information might not be output
properly to the log host.
d. Display the process ID of syslogd, kill the syslogd process, and then restart syslogd using
the –r option to make the new configuration take effect.
# ps -ae | grep syslogd
147
# kill -HUP 147
# syslogd -r &
Now, the device can output FTP logs to the log host, which stores the logs to the specified file.

Configuration example for outputting logs to a Linux log host

Network requirements
Configure the device to output to the Linux log host 1.2.0.1/16 FTP logs that have a severity level of
at least informational.
Figure 26 Network diagram
Configuration procedure
Before the configuration, make sure the device and the log host can reach each other. (Details not
shown.)
1. Configure the device:
# Enable the information center.
<Device> system-view
[Device] info-center enable
# Specify the log host 1.2.0.1/16, and specify local5 as the logging facility.
[Device] info-center loghost 1.2.0.1 facility local5
# Disable log output to the log host.
[Device] info-center source default loghost deny
To avoid outputting unnecessary information, disable all modules from outputting log
information to the specified destination (loghost in this example) before you configure an
output rule.
