+# Thresholding:
+#
+# This feature is used to reduce the number of logged alerts for noisy rules.
+# Thresholding commands limit the number of times a particular event is logged
+# during a specified time interval.
+#
+# The syntax is the following:
+#
+# threshold gen_id <gen_id>, sig_id <sig_id>, type <limit|threshold|both>, track <by_src|by_dst>, count <n>, seconds <t>
+#
+# event_filter gen_id <gen_id>, sig_id <sig_id>, type <limit|threshold|both>, track <by_src|by_dst>, count <n>, seconds <t>
+#
+# suppress gen_id <gid>, sig_id <sid>
+# suppress gen_id <gid>, sig_id <sid>, track <by_src|by_dst>, ip <ip|subnet>
+#
+# The options are documented at https://docs.suricata.io/en/latest/configuration/global-thresholds.html
+#
+# Please note that thresholding can also be set inside a signature. The interaction between rule based thresholds
+# and global thresholds is documented here:
+# https://docs.suricata.io/en/latest/configuration/global-thresholds.html#global-thresholds-vs-rule-thresholds
+
+# Limit to 10 alerts every 10 seconds for each source host
+#threshold gen_id 0, sig_id 0, type limit, track by_src, count 10, seconds 10
+
+# Limit to 1 alert every 10 seconds for signature with sid 2404000 per destination host
+#threshold gen_id 1, sig_id 2404000, type limit, track by_dst, count 1, seconds 10
