   Table 1 Alarm handling methods

   Parameter	Description
   Action	Mark as handled For a manually handled event, you can add remarks to record the details about the event. Ignore Ignore the current alarm. Any new alarms of the same type will still be reported by HSS. Add to alarm whitelist Add false alarmed items to the login whitelist. HSS will no longer report alarm on the whitelisted items. A whitelisted alarm will not trigger alarms. After adding an alarm to the alarm whitelist, you can customize a whitelist rule. The custom rule types vary depending on the alarm types, including the file path, process path, process command line, remote IP address, and user name. By default, HSS automatically fills in the rule based on the alarm summary. You can modify the rule as required. If a detected alarm event hit the rule you specified, HSS does not generate an alarm. Isolate and kill If a program is isolated and killed, its executable file status will change to read-only, and the program will be terminated immediately. To avoid impact on services, exercise caution when performing this operation. Isolated source files of programs or processes are displayed on the Isolated Files slide-out panel and cannot harm your servers. You can click Isolated Files on the upper right corner to check the files. For details, see Managing Isolated Files.
   Batch Handle	If this option is selected, the same alarms triggered at different time are handled in batches. If no duplicate alarm is displayed after you select it, it indicates no duplicate alarms have been generated.
   Remarks	You can add remarks for convenient backtracking.
