To optimize searches in the Event Console archive files, the Event Console uses "grep" to make a fast preselection of history entries. The grep command is used for different filters, like the "ID of rule". This allows normal logged in users with only GUI privileges to execute shell commands on the monitoring host with privileges of the user the Event Console is running with. Normally this is the sites user in OMD sites or the user nagios.
