+description: Manages F5 BIG-IP LTM udp monitors.
+version_added: "2.5"
+options:
+  name:
+    description:
+      - Monitor name.
+    required: True
+    aliases:
+      - monitor
+  parent:
+    description:
+      - The parent template of this monitor template. Once this value has
+        been set, it cannot be changed. By default, this value is the C(udp)
+        parent on the C(Common) partition.
+    default: "/Common/udp"
+  send:
+    description:
+      - The send string for the monitor call. When creating a new monitor, if
+        this value is not provided, the default C(default send string) will be used.
+  receive:
+    description:
+      - The receive string for the monitor call.
+  receive_disable:
+    description:
+      - This setting works like C(receive), except that the system marks the node
+        or pool member disabled when its response matches the C(receive_disable)
+        string but not C(receive). To use this setting, you must specify both
+        C(receive_disable) and C(receive).
+  ip:
+    description:
+      - IP address part of the IP/port definition. If this parameter is not
+        provided when creating a new monitor, then the default value will be
+        '*'.
+  port:
+    description:
+      - Port address part of the IP/port definition. If this parameter is not
+        provided when creating a new monitor, then the default value will be
+        '*'. Note that if specifying an IP address, a value between 1 and 65535
+        must be specified.
+  interval:
+    description:
+      - The interval specifying how frequently the monitor instance of this
+        template will run. If this parameter is not provided when creating
+        a new monitor, then the default value will be 5. This value B(must)
+        be less than the C(timeout) value.
+  timeout:
+    description:
+      - The number of seconds in which the node or service must respond to
+        the monitor request. If the target responds within the set time
+        period, it is considered up. If the target does not respond within
+        the set time period, it is considered down. You can change this
+        number to any number you want, however, it should be 3 times the
+        interval number of seconds plus 1 second. If this parameter is not
+        provided when creating a new monitor, then the default value will be 16.
+  time_until_up:
+    description:
+      - Specifies the amount of time in seconds after the first successful
+        response before a node will be marked up. A value of 0 will cause a
+        node to be marked up immediately after a valid response is received
+        from the node. If this parameter is not provided when creating
+        a new monitor, then the default value will be 0.
+  partition:
+    description:
+      - Device partition to manage resources on.
+    default: Common
+    version_added: 2.5
+notes:
+  - Requires the f5-sdk Python package on the host. This is as easy as pip
+    install f5-sdk.
+  - Requires BIG-IP software version >= 12
+requirements:
+  - f5-sdk >= 2.2.3
