There are a few monitoring server configuration settings that you might
want to change from the default values. Consider changing the following settings
to ensure a smooth running environment even as your environment scales.
KDS_NCSLISTEN
This is the number of active listening threads and the default is 10.
This must be extended.
Recommendation: 255 threads for large environments. Because there is a
memory impact using a large setting, reduce this number for smaller environments.
KDCFC_RXLIMIT
This is the buffer used for return queries, specified in KB. The default
value is 2048 KB (equivalent to 2 MB). A value of 8192 KB (equivalent to 8
MB) seems to work well for most users.
Recommendation: 8192 KB
DEPOTHOME
The location of the depot. The default location is
Windows® %CANDLE_HOME%\CMS\Depot
Linux® and UNIX® $CANDLEHOME/tables/<hub tems name>/depot
Relocating the depot directory enables you to backup
your Tivoli Monitoring environment without having to backup the very large depot
directory. In addition, relocating the depot directory ensures that the depot
will not fill up the filesystem where Tivoli Monitoring is running.
The target
directories listed below are examples:
If CANDLE_HOME on Windows is
located at C:\IBM\ITM, then relocate the depot
to D:\ITM\depot
If CANDLE_HOME on Linux and UNIX is located at /opt/IBM/ITM, then relocate the depot to /data/ITM/depot
By setting the variable in the env.config file,
it remains unchanged when maintenance is applied to your monitoring server. If you
put this into your KBBENV file, it is overwritten
when maintenance is applied.
Bind a specific IP address
KDEB_INTERFACELIST=192.100.100.100
Note:
Use this option only if the monitoring server and portal server are
on separate servers. If they are on the same computer there are going to be
problems due to the multiplexed port 1920. The tacmd command cannot find the monitoring server,
and portal cannot find the portal server.
Bind a specific host name
KDEB_INTERFACELIST=caps001
Bind the first IPV4 address associated with the current host name to be
the default interface.
KDEB_INTERFACELIST=!*
Use an IPV4 symbolic name
KDEB_INTERFACELIST=!en0
There are many other optional parameters documented in the IBM Tivoli Monitoring Administrator's
Guide. Review those parameters and determine whether any are required
for your environment. See Tivoli Enterprise Monitoring Server for information on monitoring
server parameters for performance tuning.
