Outputting Log Information To A Linux Log Host - HP MSR Series Configuration Manual

# Configure an output rule to output to the log host ARP and IP log information that has a severity
level of at least informational.
[Device] info-center source arp channel loghost log level informational state on trap
state off
[Device] info-center source ip channel loghost log level informational state on trap
state off
2. Configure the log host:
The following configurations were performed on Solaris which has similar configurations to the
UNIX operating systems implemented by other vendors.
a. Log in to the log host as a root user.
b. Create a subdirectory named Device in directory /var/log/, and then create file info.log in
the Device directory to save logs from Device.
# mkdir /var/log/Device
# touch /var/log/Device/info.log
c. Edit the file syslog.conf in directory /etc/ and add the following contents.
# Device configuration messages
local4.info
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:
Be aware of the following issues while editing 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 information level specified in the /etc/syslog.conf file must be
•
identical to those configured on the device 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 system can record log information into the log file.

log host at 1.2.0.1/16.
