Cisco Meraki (Preview)

The parser normalizes MX Security Appliances and MR Access Points data to a common schema based on an OpenTelemetry standard.

This schema allows you to search the data without knowing Cisco's data specifically, and just knowing the common schema instead. It also allows you to combine the data more easily with other data sources which conform to the same schema.

Note: The initial release of this package focuses exclusively on IPv4 addresses.

Preview Status

Note that this package is considered a PREVIEW. This means we are seeking feedback on the package, and may make breaking changes to the parser in the future. It means also it may not include all documentation which usually we publish for packages.

Installing the Package in LogScale

Find the repository where you want to send the Cisco Meraki events, or create a new one.

  1. Navigate to your repository in the LogScale interface, click Settings and then Packages on the left.

  2. Click Marketplace and install the LogScale package for Cisco Meraki (i.e. cisco/meraki).

  3. When the package has finished installing, click Ingest tokens on the left (still under the Settings, see Figure 18, “Ingest Token”).

  4. In the right panel, click + Add Token to create a new token. Give the token an appropriate name (e.g. the name of the server the token is ingesting logs for), and either leave the parser unassigned (instead of setting the parser in the log collector configuration later on), or assign the cisco-meraki parser to it.

    Before leaving this page, view the ingest token and copy it to your clipboard — to save it temporarily elsewhere.

  5. Configure the syslog server to send the Cisco Meraki events to LogScale.

  6. Now that you have a repository set up in LogScale along with an ingest token you're ready to send logs to LogScale.

For more about Cisco Meraki event types and configuration, visit the Syslog Event Types and Log Samples and the Syslog Server Overview and Configuration pages.

Verify Data is Arriving in LogScale

Once you have completed the above steps the Cisco Meraki data should be arriving in your LogScale repository.

You can verify this by doing a simple search for the events:

#Vendor = "cisco" 
| Product = "meraki"

Package Contents Explained

This package is only for parsing incoming data, and normalizing the data as part of that parsing. The parser normalizes the data to a subset of this schema based on OpenTelemetry standards, while still preserving the original data.

If you want to search using the original field names and values, you can access those in the fields whose names are prefixed with the word "Vendor". Fields which are not prefixed with "Vendor" are standard fields which are either based on the schema (e.g. source.ip) or on LogScale conventions (e.g. @rawstring).

The fields which the parser currently maps the data to, are chosen based on what seems the most relevant, and will potentially be expanded in the future. But the parser won't necessarily normalize every field that has potential to be normalized.

Event Categorisation

As part of the schema, events are categorized by four different fields:

  • event.category

  • event.type

event.category and event.type are arrays, so need to be searched like so:

array:contains("event.category[]", value="network")

This will find events where some event.category[n] field contains the value "network", regardless of what `n` is. Note that not all events will be categorized to this level of detail.

Normalized Fields

Here are some of the normalized fields which are being set by this parser:

  • source.* (e.g. source.address)

  • network.* (e.g. network.direction)

  • destination.* (e.g. destination.ip, destination.port)

  • threat.* (e.g. threat.indicator)
