Collecting logs from Yokogawa FAST/TOOLS and sending them to Logstash could be complex due to this unique combination of log sources and the SIEM solution. In this post, we will look at how you can forward log data from Yokogawa FAST/TOOLS to Logstash 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 log sources mentioned above and NXLog’s features play an important role in normalizing logs to meet Logstash’s requirements.
Sending logs to Logstash
Logstash is a data collection and processing tool. It is often used as part of the ELK stack (Elasticsearch, Logstash, Kibana) to collect logs from various sources, normalize them, and forward them to Elasticsearch. NXLog and Logstash can be configured to exchange log data between each other in various formats, including JSON and syslog, and over different transport protocols such as TCP, UDP, and HTTP(S).
- NXLog as a data shipper for Logstash
-
Due to Logstash being resource-intensive and requiring Java to run, it is often used as an ingester, with different data shippers forwarding logs to it. NXLog, with its small resource footprint, can act as a data shipper for Logstash with the benefit of being an all-in-one solution. An NXLog installation can collect and process logs from different sources on the same host, all configured within a single configuration file.
- Sending logs to Logstash
-
Logstash supports data ingestion from various sources through its many input plugins and can process data in various formats by using filters and codec plugins. NXLog also offers a vast selection of output modules and extensions that can forward logs in the data formats and ingestion methods supported by Logstash.
For more information on configuring NXLog and sending logs to Logstash, see the Logstash integration guide in the NXLog User Guide.
