Version 1.45¶

Release date: 2 November, 2024 (SaaS, On-Premise to follow the next week)

Feature Enhancements¶

Lightrun Agents: HTTP Proxy Support for Agents

In some network topologies the communication between the Lightrun agent and server needs to be routed via an HTTP proxy (even if the observed application itself is not using a proxy) In such cases, Lightrun cannot rely on the application or host to route HTTP traffic through the proxy.

Administrators can now configure an HTTP proxy specifically for the Lightrun agent by configuring the Lightrun agent. This setup is supported for all Lightrun agents: Java, .NET, Node.js, and Python using a set of flags/environment variables in the agent.config files. Ensure that communication with the proxy uses the HTTPS protocol. When configuring the proxy host, set the protocol to HTTPS.

Lightrun Management Portal: Just-in-Time (JIT) Access Configurable in the UI

You can now configure and monitor Just-in-Time (JIT) Access instances directly in the Lightrun Management Portal, complementing the existing Lightrun REST API commands for JIT configuration.

Any JIT Access instances created via the REST API will automatically appear in the JIT Access list within the UI, enabling seamless management. For more information, see Configure Just-in-Time (JIT) Access in Lightrun.

Bug Fixes¶

• Fixed internal issues related to the Lightrun server.
• Fixed security vulnerabilities in the Lightrun server.

October 2024¶

Version 1.44¶

Release date: 22 October, 2024 (SaaS, On-Premise to follow the next week)

Feature Enhancements¶

Java Agent: Support for Snapshot Variable String Rendering

The Java agent now supports the Snapshot Variable String Rendering feature, designed to automatically convert specific Java objects into their string representations during snapshot creation. This ensures that predefined Java classes are rendered in a consistent, human-readable format, improving clarity and efficiency during debugging. By applying a standardized conversion method, developers can easily interpret complex variables, streamlining the troubleshooting process and reducing the need for manual conversions.

The Snapshot Variable String Rendering feature applies string representations by default to the following Java classes: java.util.UUID, java.util.Date, java.sql.Timestamp, java.sql.Time, java.sql.Date, java.time.Instant, java.time.LocalDate, java.time.LocalTime, java.time.ZonedDateTime, java.time.OffsetDateTime, and java.time.Duration.

To enable this feature, set show_string_representation_of_extra_classes to 1 in the agent.config file. For more information, see Java Agent Configuration.

Lightrun Snapshots: Gain More Control of Snapshot Maximum Hit Limits

Administrators now have greater control over the number of allowed Lightrun snapshot hits with the introduction of the Max Hits Per Snapshot parameter, available in the Service Configuration page of the Lightrun Management Portal. This new parameter complements the existing Max Hits Per Agent, which remains the default in this release. Previously, administrators could only set the maximum number of snapshot hits per agent. With this release, the global parameter allows control over the number of hits per action across all snapshots, reducing server load and optimizing performance. This feature is released with Limited Availability. To enable it, please contact your Account Manager. For more information, see Manage Global Snapshot Hit Count Limits for Plugins.

Version 1.43.0¶

Version 1.41.0¶

Release date: 11 September, 2024 (SaaS, On-Premise to follow the next week)

Highlights¶

Lightrun Management Portal: Custom SMTP Connectivity Support

Lightrun requires a functional SMTP (Simple Mail Transfer Protocol) service to automate email notifications and alerts in response to specific events. This service is essential for Lightrun’s user registration and authentication processes. By default, the Lightrun server comes with a preconfigured SMTP service.

You can choose to set up your own SMTP service if you are working in an air-gapped environment or if your organization requires an internal, dedicated SMTP service. For more information, see Set up a custom SMTP server for email notifications.

Lightrun Management Portal: SAML JIT Provisioning using Microsoft Entra ID Support

As part of our ongoing efforts to provide a seamless experience when working with Lightrun in enterprise organizations, we now offer the ability to use SAML JIT for user provisioning using Microsoft Entra ID. This enables setting up a seamless and automated user account creation process for applications integrated with Microsoft’s identity platform.

By configuring JIT provisioning, administrators can ensure that when users log in to a web application via Single Sign-On (SSO) for the first time, their account is automatically created based on the information passed through SAML assertions from Microsoft Entra ID. This removes the need for manual account creation, reducing administrative effort and enhancing the user experience during onboarding. For more information, see Provision SAML JIT using Microsoft Entra ID.

Lightrun Management Portal: OIDC SSO Ping Identity Provider Support

We have expanded our Single Sign-On (SSO) authentication capabilities to include OpenID Connect (OIDC), in addition to our existing SAML support. Ping Identity is the first OIDC Identity Provider (IdP) now supported, with additional options planned for future releases.

Configuring SSO with OIDC allows users to authenticate and access Lightrun using a single set of credentials through an OIDC IdP. Built on top of OAuth 2.0, OIDC securely transmits user identity data between the IdP and Lightrun. This streamlines authentication, with the IdP managing the login process and and providing Lightrun with user details in the form of ID tokens, reducing the need for separate login management within the platform. For more information, see Configure OIDC SSO with Ping Identity for your organization.

Feature Changes¶

Single Sign-On Mechanism Changes

For On-premise and single-tenant deployments, when clicking the Single Sign On button, users are redirected to the company's selected IdP login. The need to fill in the SSO email address as part of the SSO login process is no longer required.

LogOptimizer: Docker Client No Longer Required

You no longer need to have Docker Client installed to run LogOptimizer in your IDE.

Bug Fixes¶

• Fixed an issue, whereby the ActionUpdateThread.OLD_EDT IDE exception was displayed in the JetBrains IDE.

Release date: 25 August, 2024 (SaaS, On-Premise to follow the next week)

Bug Fixes¶

• Fixed an issue in the VS CODE IDE where the 'back' link in snapshots would incorrectly jump to the first hit instead of moving back to the snapshot.
• Fixed an issue in the VS CODE IDE for the .NET agent where variables were not displayed in the snapshot hit.

Version 1.40.0¶

Release date: 25 August, 2024 (SaaS Only)

Highlights¶

Lightrun Just-In-Time (JIT) Access Support

Lightrun supports Just-in-Time (JIT) access using a set of dedicated REST API commands. This capability enables administrators to generate ad-hoc time restricted permissions to access sensitive agent pools for predetermined periods. For more information, see Grant Just-In-Time (JIT) Access.

IT Access is designed for companies with strict policies and regulations restricting access to sensitive environments and requiring access to be granted only for the minimum period necessary. This feature allows companies to automate the provisioning of elevated permissions and manage them via existing workflow and systems external to Lightrun.

Stay tuned! In the near future, JIT Access will also be configurable manually through the Lightrun Management Portal.

Feature Enhancements¶

Lightrun Management Portal: SCIM User Management Improvements

Lightrun admins can now assign the Lightrun Admin role directly within Lightrun, rather than through SCIM, as was done previously. Additionally, we have introduced improvements to the way you assign Lightrun groups and roles to your SCIM users within the Lightrun Management Portal. If you have set up your Lightrun Admin role directly using SCIM, please reach out to your Lightrun representative to learn more about the new changes and how to prevent any potential disruptions. Note that the custom mapping to the authorities attribute is no longer required.

Lightrun Management Portal: User Loading Performance Improvement

HEADS UP NOTICE: Introducing Enhanced Login Method to the Lightrun Server

To align with industry standards and to streamline and simplify the user login process 
for the Lightrun Server, we have implemented a single login method. This strategy 
eliminates the cumbersome task of managing multiple methods in parallel by allowing 
administrators to set a single login method from three options: user-defined password, 
SSO, or Google.

From version 1.33, this new feature will be rolled out gradually and will 
only affect a number of selected customers.

So what's changed?

When you apply the new login method, you will need to select your preferred login method. 
Until you do that, your existing users will be unaffected and will be able to continue 
working, as usual. However, the administrator will not be able to add new users until you select your 
preferred login method.

Once the administrator selects the preferred login method, users will receive 
an activation email. Users' history will remain unaffected, and as soon as 
users reactivate, they will be able to pick up right where they left off.

Stay tuned for further instructions as we roll out these changes.

.NET Agent: Concurrent Support for Additional Profiling Tools

Lightrun introduces support for profiler chaining in the .NET agent allowing you to run multiple profiling tools simultaneously on the same application or system. This feature allows developers and operators to gather performance data and insights from different profiling tools concurrently without conflicts or interference.

In practical terms, profiler chaining enables the coexistence of an additional profiling agent or tool in parallel to Lightrun’s .NET agent. For example, Lightrun's .NET agent and other Application Performance Monitoring (APM) tools, such as Datadog on the same .NET application or environment. Each profiling tool can collect specific types of performance data or provide unique insights into the application's behavior. For more information, see Profile chaining for the Lightrun .NET Lightrun agent.

Java Agent: Enhanced Log File Naming Format

In our ongoing commitment to providing administrators with enhanced control over their agents, we have standardized the log naming convention. This enhancement aims to make the convention more intuitive, facilitating easier identification and detection of your logs.

The new format is: lightrun_java_agent.<PID>.<TIMESTAMP>.<LOG_ROTATION_RUNNING_INDEX>.log

An example of the new log format: lightrun_java_agent.22840.20240513-153557.1.log In the example, The new convention includes the log name - lightrun_java_agent, the log file PID - 22840, the date and time following the YYYYMMDD-HHMMSS convention - 20240513-153557, and the log rotation running index is 1.

To facilitate the transition, here is the log convention in previous versions:

In forthcoming releases, this initiative will be extended to Node.js and .NET log files.

Java, Python, and, Node.JS Agents: PII Redaction Enhancements

• PII Redaction Now Processes Complex and Nested Objects

  In this release, we have extended the support for PII redaction to nested objects to ensure comprehensive privacy protection within complex data structures, bolstering compliance efforts and minimizing the risk of data breaches. With this update, we've tackled the challenge of masking values within multi-level objects during PII Redaction by Name.

  Please note that when PII redaction is performed on Node.JS and Python languages, the nested objects will be redacted and displayed in the log lines as REDACTED. The behavior of the Lightrun Java agent differs, as it consistently masks nested objects higher than level 1 hierarchy with <<Object>>., irrespective of whether PII redaction is enabled or not. - Enhanced Rendering of Java Maps and Arrays

  From version 1.26, Lightrun has also improved the rendering of map and arrays object types.
