This example shows how to list the records
in the system event log (SEL) of a managed server. This example also shows how
to clear the records from the SEL. Clearing the log entries can save on disk
space and reduce clutter from old records in the SEL.
You can locate the instance of CIM_RecordLog
that represents the SEL by enumerating all instances
of CIM_RecordLog
and filtering out other logs by name. The log records are
associated to the CIM_RecordLog
instance.
Listing Records of the System Event
Log
shows the relationships of the CIM objects involved.
Note:
This discussion assumes that the managed
server is a single-node system.
Figure 1. Listing Records of the System Event
Log
This example shows how to get the log entries
from the Implementation namespace, assuming you already know its name. The
pseudocode in this topic depends on the pseudocode in
Make a Connection to the CIMOM.
To list and clear the System Event Log
Procedure
Connect to the server URL.
Specify the Implementation namespace,
supplied as a parameter, for the connection.
The actual namespace you will use depends on
your installation.
use wbemlib
use sys
use connection renamed cnx
connection = Null
params = cnx.get_params()
if params is Null
sys.exit( -1 )
connection = cnx.connect_to_host( params )
if connection is Null
print 'Failed to connect to: ' + params['host'] + ' as user: ' + params['user']
sys.exit( -1 )
Enumerate instance names of CIM_RecordLog.
instance_names = connection.EnumerateInstanceNames( ’CIM_RecordLog’ )
if len( instance_names ) is 0
print 'Error: No logs found on managed server.'
sys.exit( -1 )
Iterate over the log instances, rejecting
all log instances that are not named
"IPMI SEL".
for instance_name in instance_names
instance = connection.GetInstance( instance_name )
if instance[’ElementName’] is ’IPMI SEL’
print_log_entries( instance_name )
clear_log_entries( instance_name )
From the log instance that represents the
SEL, traverse the CIM_LogManagesRecord
association to reach the entries that belong to the log.
function print_log_entries( instance_name )
instances = connection.Associators( instance_name,
AssocClass = ’CIM_LogManagesRecord’ )
for instance in instances
for prop in [ ’MessageTimestamp’, ’RecordData’ ]
print ’ %28s %s’ % ( prop, instance[prop] )
On the log instance that represents the SEL,
invoke the ClearLog()
method with no parameters.
