- write a debugging message to the system log
cc [flags…] -I /usr/cluster/include file -L /usr/cluster/lib -l dsdev #include <rgm/libdsdev.h> void scds_syslog_debug(int debug_level, constchar *format...
The scds_syslog_debug() function writes a debugging message to the system log. It uses the facility returned by the scha_cluster_getlogfacility(3HA) function.
All syslog messages are prefixed with: SC[<resourceTypeName>,<resourceGroupName>,<resourceName>,<methodName>
If you specify a debug_level greater than the current debugging level being used, no information is written.
The DSDL defines the maximum debugging level, SCDS_MAX_DEBUG_LEVEL, as 9. The scds_initialize(3HA) function, which the calling program must call before scds_syslog_debug(), retrieves the current debugging level from the file: /var/cluster/rgm/rt/<resourceTypeName>/loglevel.
Caution - Messages written to the system log are not internationalized. Do not use gettext() or other message translation functions in conjunction with this function.
The following parameters are supported:
Debugging level at which this message is to be written. Valid debugging levels are between 1 and SCDS_MAX_DEBUG_LEVEL, which is defined as 9 by the DSDL. If the specified debugging level is greater than the debugging level set by the calling program, the message is not written to the system log.
Message format string, as specified by printf(3C)
Variables, indicated by the format parameter, as specified by printf(3C)
Example 1 Display All Debugging Messages
To see all debugging messages for resource type SUNW.iws, issue the following command on all nodes of your cluster
echo 9 > /var/cluster/rgm/rt/SUNW.iws/loglevel
Example 2 Suppress Debugging Messages
To suppress debugging messages for resource type SUNW.iws, issue the following command on all nodes of your cluster
echo 0 > /var/cluster/rgm/rt/SUNW.iws/loglevel
