Compatability

Known Issues

Version 1.7.5 of Google Workspace For Splunk has the following known issues:

According to stackoverflow, there are indications that the Google Apps Admin API has an unspecified delay introduced into the events that are collected. This is most likely due to how Google collects the events and the global nature of the events. To mitigate this issue, the Google Workspace For Splunk Modular Input has a built-in delay in the consumption of events. If you run the modular input at 30 minutes, there will be a 30 minute delay of events. If you run at 1 hour, there will be a 1 hour delay in events.

Configure the Admin Reports Inputs

Requires
Audit API

Each API endpoint has individual APIs that need to be enabled within https://console.developers.google.com.

For each Report that would like to be consumed, configure a new row for that report. One report per credential per row.
1. Lookback - this setting will consume that many days back from the API. This is a first-run-to-completion flag only.
2. Interval - Each report has a slightly different recommended interval.
  1. Please review https://support.google.com/a/answer/7061566 and schedule the input service interval accordingly.

Configure the Admin Usage Inputs

Requires
- Admin SDK API

GMail API (for Directory based Email Forwarding Settings Consumption)

Each API endpoint has individual APIs that need to be enabled within https://console.developers.google.com.

For each Report that would like to be consumed, configure a new row for that report. One report per credential per row.
1. Lookback - this setting will consume that many days back from the API. This is a first-run-to-completion flag only.
2. Interval - Each report has a slightly different recommended interval.
  1. Please review https://support.google.com/a/answer/7061566 and schedule the input service interval accordingly.
Usage - User, Customer, Directory
1. These should be scheduled for cron expressions to prevent massive data ingest. Typically 1 (once) per day per input.
Directory
1. If the status of email forwarding would like to be consumed, click the corresponding checkbox.
2. The forwarding address settings will be found in mail.settings.forwardingAddresses item of the directory user event.

Configure the Alert Center Inputs

Requires
Google Workspace Alert Center API

For each alert center, configure a row in the table to pull the information desired. View more information at https://developers.google.com/admin-sdk/alertcenter/reference/alert-types .

Configure the Email Alert Action

Requires
Google Workspace Gmail API

More information is located at: https://developers.google.com/workspace/gmail/api/guides . In order to use this API, an "Impersonation User" must be defined in the Credential Management.

Additionally, the SMTP Alert Action can be used with a local SMTP connection string. The format is smtp[s]://[username:password@]server:port. Splunk Cloud uses the connection string: smtp://localhost:25. The actual settings can be found in your Splunk Cloud instance under the uri /manager/search/admin/alert_actions/email?action=edit.

Jinja2 Compatibility

Both the message and the subject support templating using Jinja2 (https://pypi.org/project/Jinja2/). The variables passed are the following object:

``` { "savedsearch": string, "results_file": string, "event_fields": []string, "evts": []object, "single_email": boolean, } ```

To reference a field in the template, use the following notation:

{{evts[0].sourcetype}}

This example will use the first item in the array and use its sourcetype field name. Looping is supported via Jinja2 looping formats. If single_email is true, then evts will contain ALL the events from the search, otherwise only a single row will be provided.

The templates can be defined either in the Alert Action, or via field in result. Fields supported within the results:

body_template
recipients
cc
bcc
subject
sender

If one of those fields is detected, the value in the field will over-write the one provided in the alert action. This allows for a lookup file to be used for specific use cases, if applicable.

Configure Classroom Inputs

Requires
Google Classroom API

NOTE: Checking the Write Courses Data checkbox for ANY input will cause the input to write out ALL course metadata each pull. To keep the data down to a reasonable level, only configure 1 input to consume that data.
CourseIDs are a comma separated list of specific course ids. If empty, all will be consumed.
Most, if not all, of these could be fine at a 86400 interval.

Configure Big Query Inputs

Requires
BigQuery API

For GMail Headers: Documentation From Google
Fill out the fields for the project, dataset, table. If all tables are required from a single dataset, enter an asterisk. *
The Ingest Type is one of Row, Query, Time.
1. Row: is a full pull of the rows from the table. Be careful using on dynamic tables, if any rows are deleted, this will not work as expected.
2. Query: Place your SQL query in the Enrichment Field column. You can support checkpointing by using TIMESTAMP in the Query String. The timestamp is a 10 digit integer and is based on the last execution time of the input. THIS MAY INCUR COSTS.
3. Time: This is a very simple query. Uses a checkpoint time, and the “Time field” that is in the Enrichment Field ( iso_time for example). It will consume all fields and columns from the data. THIS MAY INCUR COSTS.
4. Virtual Row: is a pull of all the rows of VIEW, but checkpointed per vuew. This allows for a virtual table to be pulled while respecting the row counts of the larger table. This should be used with GMail Audit Logs. Dataset and Project required, any VIEWS will be queried and checkpointed. THIS MAY INCUR COSTS.
The Starting Index is a “first time only” setting. Consumption will start from that row line, and will be checkpointed after first run. This can also be a timestamp for Ingest Types of Time and Query (10 digit)
Highly environmentally dependent for speed of consumption. Work with max_rows setting to determine proper messages per interval. Default is 250,000.

Query, Virtual Row, and Time ingest types are EXPENSIVE. I AM NOT LIABLE FOR YOUR SPENDING. Queries (on-demand) \$5 per TB The first 1 TB per month is free.

Configure PubSub Inputs

Requires:

Cloud Pub/Sub API

Fill out the row with appropriate settings. Work with Max Messages to determine proper messages per interval setting for the environment.

Pubsub requires the use of grpcio binaries. Only a “many linux x64” file is included with this app. Please follow these instructions if you see any errors with the search:

index=_internal log_level=ERROR sourcetype=``google:workspaces:modularinput:pubsub''error_filename=``ga_pubsub.py'' | stats values(error_*) as error_* by input_guid input_name

Consult The Project Page and download the file that matches Python 3.7 and your filesystem. Download it to \$SPLUNK_HOME/etc/apps/google_workspace_for_splunk/lib
Cd to that same folder, and execute unzip -n \<package>.whl, or an equivalent command on the OS required.
This will install the .so file to the location required for the Scripts to work.
