Periodic Maintenance Procedures
• diskmonitor.SoftLimit—Specifies the operation that the system performs when the system reaches
the threshold number of days that is specified for the diskmonitor.Limit parameter. If this parameter
is set to true, the disk monitor decrements the value in the diskmonitor.Limit parameter one day at
a time (that is, from 7 to 6 to 5, and so on) until the disk utilization level drops below the percentage
of disk set by the diskmonitor.Threshold parameter. If this parameter is set to false, the disk monitor
closes when the system saves files continuously for the number of days set for the diskmonitor.Limit
parameter or when disk usage reaches the percentage of use set for the diskmonitor. Threshold
parameter. When disk monitor stops, the system generates a DISK alarm. The files can then be
deleted manually. The default value is false.
• diskmonitor.CoreRmDays—Specifies the number of days to keep core dump files. The default value
is 1, which means that core dump files are kept for one day before disk monitor removes them
automatically.
• diskmonitor.CfgRmDirs—This parameter specifies the maximum number of configurations that can
be stored in the configuration library. This parameter is not present in the XECfgParm.dat file
initially. The valid values are the range of integers from 3 through 64. The default value is 64.
Entering a value outside of the range of valid values disables monitoring of the number of entries
that are stored in the configuration library. To change the value of this parameter, enter it manually
into the XECfgParm.dat file.
• diskmonitor.PreserveCDRs—This parameter affects the performance of the disk monitor in
coordination with the diskmonitor.Threshold, diskmonitor.Limit, and diskmonitor.SoftLimit
parameters. If diskmonitor.PreserveCDRs is set to true, the system saves the CDR files during each
stage of the disk monitor process. If diskmonitor.PreserveCDRs is set to false, the system manages
the CDR files according to the settings of the diskmonitor.Threshold, diskmonitor.Limit, and
diskmonitor.SoftLimit parameters. That is, the system will stop saving the CDR files when disk
usage surpasses the percentage of use set by the diskmonitor.Threshold parameter.
Disk monitor performs the following steps in its inspection of disk utilization levels:
1. Verify that the standard and optional partitions, as defined in diskmonitor.OptFileSys, have not
exceeded the thresholds for disk utilization or the configuration library, as defined in
diskmonitor.Threshold and diskmonitor.CfgRmDirs, respectively.
a. If neither threshold is exceeded, disk monitor exits.
b. If the disk utilization threshold is exceeded, the disk monitor attempts to trim the files according
to the number of days defined by the diskmonitor.Limit parameter. For instance, if
diskmonitor.Limit is set to 7, the disk monitor deletes any files older than 7 days.
c. If the configuration library threshold is exceeded, disk monitor trims the number of
configuration files to match the setting in the diskmonitor.CfgRmDirs parameter, starting with
the oldest.
2. Once files are trimmed, disk monitor verifies again that the standard and optional partitions have not
exceeded the thresholds for disk utilization and the configuration library.
a. If neither threshold is exceeded, disk monitor exits.
b. If the disk utilization threshold is exceeded, and diskmonitor.SoftLimit is set to false, the system
exits disk monitor and raises a DISK alarm.
c. If the disk utilization exceeds the threshold, and diskmonitor.SoftLimit is set to true, the disk
monitor begins decreasing the number of days for which logs can be stored (the value that is
defined in diskmonitor.Limit), and stops as soon as disk utilization drops beneath the threshold
specified by the diskmonitor.Threshold parameter.
d. If the configuration library threshold is exceeded, disk monitor trims the number of
configuration files to match the setting in the diskmonitor.CfgRmDirs parameter, starting with
the oldest.
