Collecting logs from Yokogawa FAST/TOOLS and sending them to Google Chronicle could be a complex task due to this rather unique combination of log sources and SIEM solution. In this post we will take a look at how you can forward log data from Yokogawa FAST/TOOLS to Google Chronicle using NXLog.
Yokogawa FAST/TOOLS
FAST/TOOLS is Yokogawa’s SCADA software platform. Its client-server architecture comprises three main functional components: a SCADA server, a Web HMI client, and a Web HMI server. The SCADA server is responsible for collecting, processing, and managing the logs it receives from the Web HMI clients. The Web HMI server displays events and other operational data from Web HMI clients while also serving as the human-machine interface for displaying the logs that the SCADA server has processed.
FAST/TOOLS comprises several function-specific modules that include OPC server and client functionality and a history scheduler. The FAST/TOOLS software platform integrates with cloud computing and virtualization infrastructures. It is widely deployed in the oil and gas industry and large manufacturing plants worldwide.
Collecting Yokogawa FAST/TOOLS logs
FAST/TOOLS produces a wide variety of logs about its operations.
These logs are available in flat files and stored in the C:\Users\Public\Yokogawa\tls\log\ system directory.
There is no room for error or trade-offs because Yokogawa FAST/TOOLS monitors and controls the type of operations Its steady, uninterrupted operation is essential to maintaining plant safety. However, due to excessive log noise, valuable information can sometimes remain hidden in the logs it collects. Another challenge is the lack of consistent log formats. The ability to parse data from various log formats is an absolute necessity.
NXLog Enterprise Edition is a lightweight, modular log collection tool capable of tackling the most challenging cases log collection may pose. Its rich features allow it to read almost any log format and parse fields to produce structured data for further processing. It is the perfect tool for monitoring and collecting FAST/TOOLS logs.
- RDBMS data collection
-
FAST/TOOLS provides an ODBC (open database connectivity) interface that collects data from the FAST/TOOLS data set services layer and sends it directly to an external ODBC compliant database. With FAST/TOOLS, you can view table components and perform faster queries, obtaining much quicker insight into your plant operations. FAST/TOOLS includes an embedded relational database management system (RDBMS) that allows you to execute more complex queries and cross-reference FAST/TOOLS data with your own RDBMS environment.
- Collecting FAST/TOOLS logs from file
-
FAST/TOOLS' file-based logs include start logs, diagnostics logs, system monitor logs, and systems error logs. The processes that detect system errors send messages to the FAST/TOOLS unsolicited message handler (UMH), which manages all the necessary information present in these logs. This information includes the name of the process that detected the error, a timestamp, and an error code. You can view these application error logs in the
messages.umhfile of the FAST/TOOLS data directory. NXLog is capable of parsing these complex logs by using regular expressions. - FAST/TOOLS passive network monitoring
-
FAST/TOOLS supports open platform communications (OPC) functionality and includes an embedded OPC Unified Architecture (UA) environment. It also supports classic OPC for distributed communication (DCOM) links across your network. NXLog can passively monitor your network traffic and generate logs for most network protocols.
NXLog’s data normalization and log aggregation capabilities can extend the functionality of Yokogawa FAST/TOOLS. Because NXLog can collect logs from literally any file in any format, it is ideally suited for integrating with FAST/TOOLS' wide variety of log types and file formats.

The above mentioned log sources, and the features NXLog provides, all play an important role when normalizing logs to meet Google Chronicle’s requirements.
Sending logs to Google Chronicle
Google Chronicle is a cloud-based service by Google for collecting and processing log data. It can accept both structured (UDM-formatted) and unstructured messages that can be searched and selected based on specific criteria, such as assets, domains, or IP addresses.
- Chronicle Partner Ingestion API
-
Sending logs via the Ingestion API is a direct forwarding method that is more flexible and allows Chronicle to immediately parse events as they are received. The API provides endpoints for both Unified Data Model (UDM) and unstructured log entries.
- Chronicle Forwarder Software
-
Sending logs via Chronicle Forwarder offers an easier initial configuration and built-in passive network capabilities. However, its disadvantage is that it requires intermediary software to be installed on the network and can only forward unstructured logs.
A central NXLog agent can act as an enhanced replacement for Chronicle Forwarder. It too can forward unstructured and UDM-formatted data, but it provides passive network monitoring as additional functionality.
