Changing the level of detail to capture in the IBM Spectrum Symphony multicluster logs

You can change the level of detail captured in the IBM® Spectrum Symphony multicluster logs for the multicluster primary and multicluster member clusters. By default the logging level for these logs is to show informational messages. You can change the logger classes defined in the smc.master.log4j.properties (for the SMCM service) and smc.proxy.log4j.properties (for the SMCP service) files, or for a specific SMCM or SMCP service logger, using the smcadmin log command. Once run, the log level change is effective immediately and remains in effect until you restart the host, or until affected processes are closed.

Before you begin

To be able to change the multicluster, you must have SMC_LOG_CONTROL permission.

Procedure

To change the level of detailed captured for the multicluster primary cluster logs, run:
```
smcadmin log smcm -logger {smcm_all | smcm_logger} -level log_level
```
For example, to change the logging level for the multicluster primary cluster to capture debugging information for all SMCM service loggers, run:
```
smcadmin log smcm -logger smcm_all -level LOG_DEBUG
```
To change the logging level for the multicluster primary cluster to capture error messages for the smc.master.daemon SMCM service logger, run:
```
smcadmin log smcm -logger smc.master.daemon -level LOG_ERROR
```
To change the level of detailed captured in the multicluster member cluster logs, run:
```
smcadmin log smcp -logger {smcp_all | smcp_logger} -level log_level -c cluster1[,cluster2]...
```
For example, to change the logging level to capture debugging information for a multicluster member cluster (called MyCluster), for all SMCP service loggers, run:
```
smcadmin log smcp -logger smcp_all -level LOG_DEBUG -c MyCluster
```
To change the logging level to capture debugging information for two multicluster member cluster (called MyCluster1 and MyCluster2), to capture error messages for the smc.proxy.daemon SMCP service logger, run:
```
smcadmin log smcp -logger smc.proxy.daemon -level LOG_ERROR -c MyCluster1,MyCluster2
```
