Unit 3: Using Operating System



            The following table explains the different logging levels that can be configured using the   Notes
            various bit fields.

             Log Level   Bit Code    Messages Logged

             EMERG       0x0001      Information about the system being unusable

             NOTICE      0x0020      Information related to normal functioning which is significant
             INFO        0x0040      Informative messages about normal functioning
             DEBUG       0x0080      Verbose debug-level messages, useful in troubleshooting

                                     shooting


                          Levels  DEBUG  and  TRACE  generate  a  lot  of  detailed  messages  and  are
                          designed for troubleshooting. These levels are not recommended for
                          production usage.


            3.6.3 How to Configure the Hardware Management Agent Logging Level

             (a) Depending on the host operating system that the Hardware Management Agent is running
                 on, open the hwagentd.conf file from the path shown in the following table. You can use
                 any text editor to modify this file.
             (b) Find the hwagentd_log_levels parameter and enter the decimal number calculated using the
                 instructions above.

             (c) Save the modified hwagentd.conf file.
             (d) Choose one of the following options to make the Hardware Management Agent reread the
                 hwagentd.conf file:
                  • On Linux and Solaris operating systems, you can manually restart (Solaris operating
                    system: refresh) the Hardware Management Agent, which forces the hwagentd.conf
                    to be reread. Depending on the host operating system that the Hardware Management
                    Agent is running on, restart the Hardware Management Agent.
                  • On Windows operating systems, you can restart the service using the Microsoft
                    Management Console Services snap-in.
                 The Hardware Management Agent rereads the hwagentd.conf file with the modified
                 hwagentd_log_levels parameter.

            3.6.4 Configuring your Host Operating System’s SNMP
            The Hardware Management Agent uses SNMP for network communications. For the Hardware
            Management Agent to be able to use SNMP correctly on host operating systems, you must ensure
            that SNMP is configured correctly. On Linux and Solaris operating systems, the snmpd.conf
            file controls network access to the Hardware Management Agent. On Windows operating
            systems the SNMP service controls network access to the Hardware Management Agent.
