bigip_monitor_snmp_dca – Manages BIG-IP SNMP data collecting agent (DCA) monitors

New in version 2.5.

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).

Requirements

The below requirements are needed on the host that executes this module.

  • f5-sdk >= 3.0.16

Parameters

Parameter Choices/Defaults Comments
agent_type
-
    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
-
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
-
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
-
Specifies the maximum acceptable CPU usage on the target server. When creating a new monitor, the default is 80 percent.
description
-
Specifies descriptive text that identifies the monitor.
disk_coefficient
-
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
-
Specifies the maximum acceptable disk usage on the target server. When creating a new monitor, the default is 90 percent.
interval
-
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
-
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
-
Specifies the maximum acceptable memory usage on the target server. When creating a new monitor, the default is 70 percent.
name
- / required
Monitor name.
parent
-
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
-
Default:
Common
Device partition to manage resources on.
password
- / 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
provider
-
added in 2.5
Default:
None
A dict object containing connection details.
password
- / 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
- / required
The BIG-IP host.
You may omit this option by setting the environment variable F5_SERVER.
server_port
-
Default:
443
The BIG-IP server port.
You may omit this option by setting the environment variable F5_SERVER_PORT.
ssh_keyfile
-
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
-
Default:
10
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
- / required
    Choices:
  • rest
  • cli ←
Configures the transport connection to use when connecting to the remote device.
user
- / 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.
server
- / required
The BIG-IP host.
You may omit this option by setting the environment variable F5_SERVER.
server_port
-
added in 2.2
Default:
443
The BIG-IP server port.
You may omit this option by setting the environment variable F5_SERVER_PORT.
state
-
added in 2.5
    Choices:
  • present ←
  • absent
When present, ensures that the monitor exists.
When absent, ensures the monitor is removed.
time_until_up
-
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
-
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.
user
- / 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
added in 2.0
    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.
version
-
    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 the f5-sdk Python package on the host. This is as easy as pip install f5-sdk.
  • 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.
