## Purpose

Triggers an alert when vWAF has denied more requests within a given period of time than a given limit allows. You can also specify that only denials of a certain severity are taken into account, and you can determine the range of IP addresses that vWAF looks at.

:::hint{type="info"}
[Denied Requests Per Minute Event Source](docId\:y635lgN0nFG_Nwny5Z1jw) is a corresponding event (all denied requests instead of requests denied from a specific IP).

| timeframe  | vWAF can continuously analyze the most recent 1, 5, 30, or 60 minutes.<br />Period of time that vWAF looks at.                                                                                                                                                                                                                                                                                                                                                                                                                                     |
| limit      | Number of denials that are needed to trigger the event.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            |
| ip4range   | Determines the size of the IPv4 range that vWAF looks at.<br />- /0 sets a global limit.<br />This means that an alert is triggered as soon as there are more denied requests for all IP addresses combined than the given limit allows.<br />- /8 to /24 specifies a range of IP addresses (See [Specifying IP Addresses](docId\:rUMDSCo5lBgjtOsOUsY1-)).<br />- /32 sets a limit per IP address.<br />This means that an alert is only triggered if there have been more denied requests on the same IP address than allowed by the given limit. |
| ip6range   | Determines the size of the IPv6 range that vWAF looks at.<br />- /0 sets a global limit.<br />This means that an alert is triggered as soon as there are more denied requests for all IP addresses combined than the given limit allows.<br />- /16, /24, /32, /48 and /56 specifies a range of IP addresses.<br />- /64 sets a limit per network.<br />- /128 sets a limit per IP address.<br />This means that an alert is only triggered if there have been more denied requests on the same IP address than allowed by the given limit.        |
| severity   | When counting the number of denied requests, vWAF only takes into account the denials that had at least the given severity.<br />The default setting here is LOW, which means that all denied requests are counted.<br />For details on severity, see [Severity of Events Triggered by Handlers](docId\:ZAdDmUem6-P614MEP_3aQ).                                                                                                                                                                                                                    |
| msg prefix | Here you can enter some text, which is added to the beginning of the issued alert.<br />The default text is "requests per client ip per severity for this application are over the configured limit:".                                                                                                                                                                                                                                                                                                                                             |
