## Synopsis

- The BIG-IP has an SNMP data collecting agent (DCA) that can query remote SNMP agents of various types, including the UC Davis agent (UCD) and the Windows 2000 Server agent (WIN2000).

## Parameters

Parameter | Choices/Defaults | Comments
--- | --- | ---

agent_type
string

Choices:
- UCD
- WIN2000
- GENERIC

Specifies the SNMP agent running on the monitored server. When creating a new monitor, the default is `UCD` (UC-Davis).

community string |  | Specifies the community name that the system must use to authenticate with the host server through SNMP. When creating a new monitor, the default value is `public`. Note that this value is case sensitive.
cpu_coefficient string |  | Specifies the coefficient that the system uses to calculate the weight of the CPU threshold in the dynamic ratio load balancing algorithm. When creating a new monitor, the default is `1.5`.
cpu_threshold integer |  | Specifies the maximum acceptable CPU usage on the target server. When creating a new monitor, the default is `80` percent.
description string |  | Specifies descriptive text that identifies the monitor.
disk_coefficient string |  | Specifies the coefficient that the system uses to calculate the weight of the disk threshold in the dynamic ratio load balancing algorithm. When creating a new monitor, the default is `2.0`.
disk_threshold integer |  | Specifies the maximum acceptable disk usage on the target server. When creating a new monitor, the default is `90` percent.
interval integer |  | Specifies, in seconds, the frequency at which the system issues the monitor check when either the resource is down or the status of the resource is unknown. When creating a new monitor, the default is `10`.
memory_coefficient string |  | Specifies the coefficient that the system uses to calculate the weight of the memory threshold in the dynamic ratio load balancing algorithm. When creating a new monitor, the default is `1.0`.
memory_threshold integer |  | Specifies the maximum acceptable memory usage on the target server. When creating a new monitor, the default is `70` percent.
name string / required |  | Monitor name.
parent string | Default: "/Common/snmp_dca" | The parent template of this monitor template. Once this value has been set, it cannot be changed. By default, this value is the `snmp_dca` parent on the `Common` partition.
partition string | Default: "Common" | Device partition to manage resources on.
provider dictionary added in 2.5 |  | A dict object containing connection details.
| auth_provider string |  | Configures the auth provider for to obtain authentication tokens from the remote device. This option is really used when working with BIG-IQ devices.
| password string / required |  | The password for the user account used to connect to the BIG-IP. You may omit this option by setting the environment variable `F5_PASSWORD`. aliases: pass, pwd
| server string / required |  | The BIG-IP host. You may omit this option by setting the environment variable `F5_SERVER`.
| server_port integer | Default: 443 | The BIG-IP server port. You may omit this option by setting the environment variable `F5_SERVER_PORT`.
| ssh_keyfile path |  | Specifies the SSH keyfile to use to authenticate the connection to the remote device. This argument is only used for cli transports. You may omit this option by setting the environment variable `ANSIBLE_NET_SSH_KEYFILE`.
| timeout integer |  | Specifies the timeout in seconds for communicating with the network device for either connecting or sending commands. If the timeout is exceeded before the operation is completed, the module will error.

transport
string

Choices:
- cli
- rest ←

Configures the transport connection to use when connecting to the remote device.

| user string / required |  | The username to connect to the BIG-IP with. This user must have administrative privileges on the device. You may omit this option by setting the environment variable `F5_USER`.

validate_certs
boolean

Choices:
- no
- yes ←

If `no`, SSL certificates are not validated. Use this only on personally controlled sites using self-signed certificates.
You may omit this option by setting the environment variable `F5_VALIDATE_CERTS`.

state
string
added in 2.5

Choices:
- present ←
- absent

When `present`, ensures that the monitor exists.
When `absent`, ensures the monitor is removed.

time_until_up
integer

Specifies the number of seconds to wait after a resource first responds correctly to the monitor before setting the resource to 'up'. During the interval, all responses from the resource must be correct. When the interval expires, the resource is marked 'up'. A value of 0, means that the resource is marked up immediately upon receipt of the first correct response. When creating a new monitor, the default is `0`.

timeout
integer

Specifies the number of seconds the target has in which to respond to the monitor request. When creating a new monitor, the default is `30` seconds. 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'. When this value is set to 0 (zero), the system uses the interval from the parent monitor. Note that `timeout` and `time_until_up` combine to control when a resource is set to up.

version
string

Choices:
- v1
- v2c

Specifies the version of SNMP that the host server uses. When creating a new monitor, the default is `v1`. When `v1`, specifies that the host server uses SNMP version 1. When `v2c`, specifies that the host server uses SNMP version 2c.

## Notes

Note

- Requires BIG-IP software version >= 12

- This module does not support the `variables` option because this option is broken in the REST API and does not function correctly in `tmsh`; for example you cannot remove user-defined params. Therefore, there is no way to automatically configure it.

- For more information on using Ansible to manage F5 Networks devices see https://www.ansible.com/integrations/networks/f5.

- Requires BIG-IP software version >= 12.

- The F5 modules only manipulate the running configuration of the F5 product. To ensure that BIG-IP specific configuration persists to disk, be sure to include at least one task that uses the bigip_config module to save the running configuration. Refer to the module’s documentation for the correct usage of the module to save your running configuration.

## Examples

    - name: Create SNMP DCS monitor
      bigip_monitor_snmp_dca:
        name: my_monitor
        state: present
        provider:
          server: lb.mydomain.com
          user: admin
          password: secret
      delegate_to: localhost

    - name: Remove TCP Echo Monitor
      bigip_monitor_snmp_dca:
        name: my_monitor
        state: absent
        provider:
          server: lb.mydomain.com
          user: admin
          password: secret
      delegate_to: localhost
