These parameters are set in the gpperfmon.conf file located at $MASTER_DATA_DIRECTORY/gpperfmon/conf directory.
1. warning_disk_space_percentage: This should be a percentage between 0 and 100 and should be less than the error_disk_space_percentage. If a filesystem’s disk space used percentage equals or exceeds this value a warning will be logged and a warning email/snmp trap may be sent. If this configuration is set to 0 or not specified, no warnings are sent.
warning_disk_space_percentage = 80
2. error_disk_space_percentage: This should be a percentage between 0 and 100 and should be greater than the warning_disk_space_percentage. If a
filesystem’s disk space used percentage equals or exceeds this value an error will be logged and a error email/snmp trap may be sent. If this configuration is set to 0 or not specified, no errors are sent.
error_disk_space_percentage = 90
3. disk_space_interval: This is the interval in minutes that limits the number of error/warning messages that are sent. The minimum value for this configuration is 1. Setting this to 0 or not specifying this configuration results in it getting set to the minimum.
disk_space_interval = 60
4. max_disk_space_messages_per_interval: This is the maximum number of error/warning messages that will be sent in the disk_space_interval. The maximum value for this configuration is 50. The minimum value for this configuration is 1. Setting this configuration to greater than 50 or not specifying this configuration results in it getting set to the maximum.
max_disk_space_messages_per_interval = 10
