Understanding What Each Field Represents
Before you change GlobalScan thresholds, refer to the table below for a description of each field that you can control and the associated setting name that will be used later in this article.
| Performance Field | Description | DataStore setting name | uptime.conf setting name |
| TOT | The overall total CPU % busy. | gs_cpu_warn gs_cpu_crit | globalscan.cpu.warn globalscan.cpu.crit |
| % Used | The capacity of the file system that is most full on the element. | gs_diskfull_warn gs_diskfull_crit | globalscan.diskfull.warn globalscan.diskfull.crit |
| % Busy | The work time of the busiest spindle on the element. | gs_diskbusy_warn gs_diskbusy_crit | globalscan.diskbusy.warn globalscan.diskbusy.crit |
| Swap Used | Total swap space used. | gs_swap_warn gs_swap_crit | globalscan.swap.warn globalscan.swap.crit |
...
Each field has two setting names: one to control the warning (yellow) threshold and another to set the critical (red) threshold. Either or both settings can be modified. The setting to update for warning thresholds includes the word warn in the setting and the critical threshold setting includes the word crit in the setting name.

Changing Thresholds for all Elements
To change the current thresholds for all elements within your up.time installation, complete the following steps:
- Connect to your up.time DataStore using an ODBC or database tool. Assuming that you have installed up.time in the default location, you can access the DataStore at the command line using the following commands:
Code Block language c# «change to the up.time installation directory»
cd mysql
cd bin
./mysql -u uptime --password=uptime -P 3308 --protocol=TCP uptime
- After you login to the up.time DataStore, run a command to update the threshold that you want to use with all elements. The command format and an example are detailed below. Replace the «field» text in the example below with a value from the DataStore setting name column in the table above. Replace the «new value» text in the example below with your new threshold setting (decimal values are not permitted for thresholds).
Note: All mysql commands assume that you are using a MySQL DataStore. The format of the commands may differ slightly for Oracle or SQL Server databases.
mysql» update entity set «field»=«new value»;
Example
mysql» update entity set gs_swap_warn=50
mysql» update entity set gs_swap_crit=75 - Run the command above for each threshold value that you want to change. When you are finished, use the exit; command to be returned to the command line.
