module: rax_mon_check
short_description: Create or delete a Rackspace Cloud Monitoring check for an
existing entity.
description:
- Create or delete a Rackspace Cloud Monitoring check associated with an
existing rax_mon_entity. A check is a specific test or measurement that is
performed, possibly from different monitoring zones, on the systems you
monitor. Rackspace monitoring module flow | rax_mon_entity ->
*rax_mon_check* -> rax_mon_notification -> rax_mon_notification_plan ->
rax_mon_alarm
version_added: "2.0"
options:
state:
description:
- Ensure that a check with this C(label) exists or does not exist.
choices: ["present", "absent"]
entity_id:
description:
- ID of the rax_mon_entity to target with this check.
required: true
label:
description:
- Defines a label for this check, between 1 and 64 characters long.
required: true
check_type:
description:
- The type of check to create. C(remote.) checks may be created on any
rax_mon_entity. C(agent.) checks may only be created on rax_mon_entities
that have a non-null C(agent_id).
choices:
- remote.dns
- remote.ftp-banner
- remote.http
- remote.imap-banner
- remote.mssql-banner
- remote.mysql-banner
- remote.ping
- remote.pop3-banner
- remote.postgresql-banner
- remote.smtp-banner
- remote.smtp
- remote.ssh
- remote.tcp
- remote.telnet-banner
- agent.filesystem
- agent.memory
- agent.load_average
- agent.cpu
- agent.disk
- agent.network
- agent.plugin
required: true
monitoring_zones_poll:
description:
- Comma-separated list of the names of the monitoring zones the check should
run from. Available monitoring zones include mzdfw, mzhkg, mziad, mzlon,
mzord and mzsyd. Required for remote.* checks; prohibited for agent.* checks.
target_hostname:
description:
- One of `target_hostname` and `target_alias` is required for remote.* checks,
but prohibited for agent.* checks. The hostname this check should target.
Must be a valid IPv4, IPv6, or FQDN.
target_alias:
description:
- One of `target_alias` and `target_hostname` is required for remote.* checks,
but prohibited for agent.* checks. Use the corresponding key in the entity's
`ip_addresses` hash to resolve an IP address to target.
details:
description:
- Additional details specific to the check type. Must be a hash of strings
between 1 and 255 characters long, or an array or object containing 0 to
256 items.
disabled:
description:
- If "yes", ensure the check is created, but don't actually use it yet.
choices: [ "yes", "no" ]
metadata:
description:
- Hash of arbitrary key-value pairs to accompany this check if it fires.
Keys and values must be strings between 1 and 255 characters long.
period:
description:
- The number of seconds between each time the check is performed. Must be
greater than the minimum period set on your account.
timeout:
description:
- The number of seconds this check will wait when attempting to collect
results. Must be less than the period.
