f5networks.f5_modules.bigip_monitor_snmp_dca module – Manages BIG-IP SNMP data collecting agent (DCA) monitors

Note

This module is part of the f5networks.f5_modules collection (version 1.18.0).

You might already have this collection installed if you are using the ansible package. It is not included in ansible-core. To check whether it is installed, run ansible-galaxy collection list.

To install it, use: ansible-galaxy collection install f5networks.f5_modules.

To use it in a playbook, specify: f5networks.f5_modules.bigip_monitor_snmp_dca.

New in version 1.0.0: of f5networks.f5_modules

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

Comments

agent_type

string

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

Choices:

  • UCD

  • WIN2000

  • GENERIC

community

string

Specifies the community name the system must use to authenticate with the host server through SNMP. When creating a new monitor, the default value is public. This value is case sensitive.

cpu_coefficient

string

Specifies the coefficient 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 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 the frequency, in seconds, 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 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

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.

Default: “/Common/snmp_dca”

partition

string

Device partition to manage resources on.

Default: “Common”

provider

dictionary

added in 1.0.0 of f5networks.f5_modules

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.

no_f5_teem

boolean

If yes, TEEM telemetry data is not sent to F5.

You may omit this option by setting the environment variable F5_TELEMETRY_OFF.

Previously used variable F5_TEEM is deprecated as its name was confusing.

Choices:

  • no ← (default)

  • yes

password

aliases: pass, pwd

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.

server

string / required

The BIG-IP host.

You may omit this option by setting the environment variable F5_SERVER.

server_port

integer

The BIG-IP server port.

You may omit this option by setting the environment variable F5_SERVER_PORT.

Default: 443

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

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

Choices:

  • rest ← (default)

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

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.

Choices:

  • no

  • yes ← (default)

state

string

When present, ensures the monitor exists.

When absent, ensures the monitor is removed.

Choices:

  • present ← (default)

  • absent

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

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

Choices:

  • v1

  • v2c

Notes

Note

  • Requires BIG-IP software version >= 12

  • This module does not support the variables option because it 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 f5networks.f5_modules.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.
