Implement- Reset System Restore Disk Space Usage
Implementation Steps
- 
Obtain the group ID(s) of the group(s) that the remote monitor should be applied to. 
- 
Copy the following query and replace YOUR COMMA SEPARATED LIST OF GROUPID(S) with the Group ID(s) of the relevant groups: (The string to replace can be found at the very bottom of the query, right after WHERE) INSERT INTO groupagents
 SELECT '' as `AgentID`,
 `groupid` as `GroupID`,
 '0' as `SearchID`,

 FROM mastergroups m
 WHERE m.groupid IN (2,144)

- 
Now execute your query from a RAWSQL monitor set. 
- 
Locate your remote monitor by opening the group(s) remote monitors tab, then apply the appropriate alert template.
