cost

Filter resources by the cost consumed over a timeframe.

Total cost for the resource includes costs for all of it child resources if billed separately (e.g. SQL Server and SQL Server Databases). Warning message is logged if we detect different currencies.

Timeframe options:

  • Number of days before today

  • All days in current calendar period until today:

    • WeekToDate

    • MonthToDate

  • All days in the previous calendar period:

    • TheLastMonth

    • TheLastBillingMonth

The diagnostic settings filter is implicitly just the ValueFilter on the diagnostic settings for an azure resource.

example

Find Load Balancers that have logs for both LoadBalancerProbeHealthStatus category and LoadBalancerAlertEvent category enabled. The use of value_type: swap is important for these examples because it swaps the value and the evaluated key so that it evaluates the value provided is in the logs.

firewall-rules

Filters resources by the firewall rules

Rules can be specified as x.x.x.x-y.y.y.y or x.x.x.x or x.x.x.x/y.

With the exception of equal all modes reference total IP space and ignore specific notation.

include: True if all IP space listed is included in firewall.

any: True if any overlap in IP space exists.

only: True if firewall IP space only includes IPs from provided space (firewall is subset of provided space).

equal: the list of IP ranges or CIDR that firewall rules must match exactly.

IMPORTANT: this filter ignores all bypass rules. If you want to ensure your resource is not available for other Azure Cloud services or from the Portal, please use firewall-bypass filter.

marked-for-op

Filter resources for tag specified future action

Filters resources by a ‘custodian_status’ tag which specifies a future date for an action.

The filter parses the tag values looking for an ‘op@date’ string. The date is parsed and compared to do today’s date, the filter succeeds if today’s date is gte to the target date.

The optional ‘skew’ parameter provides for incrementing today’s date a number of days into the future. An example use case might be sending a final notice email a few days before terminating an instance, or snapshotting a volume prior to deletion.

The optional ‘skew_hours’ parameter provides for incrementing the current time a number of hours into the future.

Optionally, the ‘tz’ parameter can get used to specify the timezone in which to interpret the clock (default value is ‘utc’)

example

policies:
 - name: vm-stop-marked
   resource: azure.vm
   filters:
     - type: marked-for-op
       # The default tag used is custodian_status

Generic reduce filter to group, sort, and limit your resources.

This example will select the longest running instance from each ASG, then randomly choose 10% of those, maxing at 15 total instances.

resource-lock

Filter locked resources. Lock can be of 2 types: ReadOnly and CanNotDelete. To filter any lock, use “Any” type. Lock type is optional, by default any lock will be applied to the filter. To get unlocked resources, use “Absent” type.

example

Get all keyvaults with ReadOnly lock:

policies:
 - name: locked-keyvaults
   resource: azure.keyvault
   filters:
     - type: resource-lock
       lock-type: ReadOnly
example

Get all locked sqldatabases (any type of lock):

policies:
 - name: locked-sqldatabases
   resource: azure.sqldatabase
   filters:
     - type: resource-lock
example

Get all unlocked resource groups:

policies:
 - name: unlock-rgs
   resource: azure.resourcegroup
   filters:
     - type: resource-lock
       lock-type: Absent
properties:

storage-diagnostic-settings

example

Find all storage accounts that have a ‘delete’ logging setting disabled.

policies:
    - name: find-accounts-with-delete-logging-disabled
      resource: azure.storage
      filters:
        - or:
            - type: storage-diagnostic-settings
              storage-type: blob
              key: logging.delete
              op: eq
              value: False
            - type: storage-diagnostic-settings

              op: eq
              value: False
            - type: storage-diagnostic-settings
              storage-type: table
              key: logging.delete
              op: eq
              value: False
example

Find Load Balancers that have logs for both LoadBalancerProbeHealthStatus category and LoadBalancerAlertEvent category enabled. The use of value_type: swap is important for these examples because it swaps the value and the evaluated key so that it evaluates the value provided is in the logs.

  - name: find-load-balancers-with-logs-enabled
    resource: azure.loadbalancer
    filters:
      - type: diagnostic-settings
