Collecting logs from Schneider Electric EcoStruxure Process Expert and sending them to Sumo Logic could be complex due to this unique combination of log source and SIEM. This post will show you how to forward log data from Process Expert to Sumo Logic using NXLog.
Process Expert is a scalable multi-engineering environment and distributed control system (DCS) from Schneider Electric. It is based on a client-server architecture that can easily adapt to the needs and scope of your plant. Process Expert provides numerous advantages, substantially reducing maintenance and engineering costs by centralizing its hardware and software configuration. It does not only reduce human error but also increases plant efficiency by simplifying installation and system design. Due to its unique model and multiuser environment, collaborating on projects is more concurrent, giving engineers the power to work on various tasks simultaneously.
The main components of Process Expert work together seamlessly to play an integral role in monitoring plant operation. The system server manages system data and client requests. The operation clients provide a user-friendly interface for monitoring system components during runtime, while the Engineering clients provide a user interface to access specific software resources. Virtual machines offer software participant services, and the database stores and manages user data.
Process Expert is used in the oil and gas, power generation, chemicals, water, and mining industries.
Process Expert provides valuable information about its operation from the logs it generates. Some of these logs are available through Windows Event Log and network monitoring, but most of them are in the format of flat files.
Due to the critical nature and scope of the systems Process Expert controls, there is no room for error. Its stable, uninterrupted operation is crucial for plant safety. However, this valuable information can sometimes remain hidden in the logs it collects due to excessive log noise. 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 complex cases log collection may pose. Due to its rich features, it can read almost any log format and parse fields to produce structured data for further processing. It is the perfect tool for monitoring and collecting Process Expert logs for these reasons.
- Collecting Schneider Electric EcoStruxure Process Expert logs from Windows Event Log
Windows Event Log is the logging subsystem on the Windows platform. The logs generated by Process Expert include the Data Access log, sysInfo log, Servertrace log, and Communication log. NXLog can easily read and collect these events by specifying a Process Expert source name or event ID from the Application channel of Windows Event Log. A special, lightweight module that can natively read data from WEL provides this functionality.
- Collecting Schneider Electric EcoStruxure Process Expert logs from file
Schneider Electric EcoStruxure Process Expert file-based logs include Server log, ServerTrace log, Engineering client log, and Operation log. These logs are stored in the
C:\Users\<Username>\AppData\Roaming\Schneider Electric\Process Expert 2020 R2\Logsdirectory but do not follow a consistent formatting scheme. NXLog’s rich set of features can efficiently read and parse such file-based logs and reliably forward them to your preferred SIEM solution.
- Schneider Electric EcoStruxure Process Expert network monitoring
NXLog can passively monitor network traffic and generate logs for most network protocols. This ability to log network communication from Schneider Electric EcoStruxure Process Expert, and integrated devices, can provide another valuable log source.
NXLog can also normalize and aggregate Schneider Electric EcoStruxure Process Expert logs. With its ability to collect logs from literally any file, in any format, NXLog is ideally suited for integrating with Process Expert’s wide variety of log types and file formats.
For more information on integrating NXLog with Schneider Electric EcoStruxure Process Expert, see the Schneider Electric EcoStruxure Process Expert integration guide.
The log sources mentioned above and NXLog’s features play an important role in normalizing logs to be accepted by Sumo Logic.
Sumo Logic is a real-time SaaS platform that collects, manages, and analyzes log data while securing cloud-scale applications. NXLog can be configured to send log data to Sumo Logic in syslog format over TCP or via a custom HTTP endpoint. It can also be configured to send host metrics via HTTP.
- Data collection
Sumo Logic accepts data from two types of collectors, installed or hosted. Installed collectors are set up by installing agent software provided by Sumo Logic, whereas hosted collectors are used to send data over TCP or HTTP(S) from agents like NXLog.
- Sending logs using TCP
Sumo Logic accepts log data as syslog messages in IETF (RFC 5424) format and requires sending data using TLS v1.2 over TCP. A Cloud Syslog Source must be created in Sumo Logic to use this method. Syslog messages should fully comply with RFC 5424 guidelines, otherwise Sumo Logic will drop them. Also, it should be noted that messages larger than 64 KB will be truncated.
- Sending logs using HTTPS
Logs and host metrics can be sent to Sumo Logic over HTTP(S) using a unique URL generated for each source. An HTTP Logs & Metrics Source must be created in Sumo Logic for NXLog to be able to send data over HTTPS.
For more information on configuring NXLog and sending logs to Sumo Logic, see the Sumo Logic integration guide in the NXLog User Guide.
