Collecting logs from Schneider Citect SCADA and sending them to Sumo Logic could be complex because of the unique combination of the log source and the desired destination. This post will show you how to forward log data from Schneider Citect SCADA to Sumo Logic by incorporating the NXLog log collection tool.
Schneider Citect SCADA
Citect SCADA is a Supervisory Control and Data Acquisition solution from Schneider Electric that is typically deployed in the manufacturing industry for monitoring and controlling production equipment and the delivery of utilities. Citect SCADA can monitor your operational systems in real time and retrieve important plant-related data since it is the primary user interface in your production environment. It is used in large manufacturing plants as well as smaller facilities for analyzing data using enhanced configuration capabilities.
Collecting Citect SCADA logs
Citect SCADA produces a wide variety of logs about its operation. Some of these logs are maintained in Windows Event Log, but most are available only as flat files.
Due to the critical nature and scope of the systems Citect SCADA controls, there is no room for error. Its stable, uninterrupted operation is crucial to plant safety. Although the logs Citect SCADA generates contain valuable information about the systems it controls, the relatively high level of log noise and the lack of a consistent log format present some challenges.
NXLog Enterprise Edition is a lightweight, modular log collection tool capable of tackling the most demanding 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 Citect SCADA logs.
- Collecting Citect SCADA logs from Windows Event Log
-
Windows Event Log is the primary logging facility on the Windows platform. The logs Citect SCADA generates contain driver traffic, updates, and system-related information. Citect SCADA creates two separate Windows Event Log entries for Schneider Electric: SUT Service for Schneider Electric software updates and Runtime Manager logs. It can also read data directly from the Schneider Electric SUT Service source.
- Collecting Citect SCADA logs from file
-
File-based Citect SCADA logs include changelog, syslog, tracelog, and software update logs. These logs are stored in the C:\ProgramData\Schneider Electric\Citect SCADA 2018\Logs directory and, in most cases, do not follow a consistent formatting scheme.
- Network Monitoring on Citect SCADA
-
NXLog has a unique feature that enables it to collect events from the communication channels between Citect SCADA devices and other computers on the network. NXLog’s passive monitoring of network traffic along with its ability to monitor most network protocols commonly used by SCADA systems, and generate logs from such network activity, make it a valuable logging tool when used with Citect SCADA.
The easiest way to collect and normalize Citect SCADA log data is to use NXLog. With its unique capabilities, it can collect logs from literally any file in any format. Given the wide variation in format and structure of such log files, NXLog is ideally suited for these systems.
For more information on integrating NXLog with Citect SCADA, see the Schneider Electric Citect SCADA integration guide.
The sources mentioned above and NXLog’s features play an important role in normalizing logs accepted by Sumo Logic.
Sending logs to 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.
Sumo Logic supports metrics in the Graphite, Carbon 2.0, and Prometheus formats. NXLog can be configured to convert data into practically any desired format. It can read and convert the data to another format on the fly while forwarding, without the need to create a temporary file.
For more information on configuring NXLog and sending logs to Sumo Logic, see the Sumo Logic integration guide in the NXLog User Guide.
