We're still excited! This time about beefing up our default grouping algorithm to significantly improve the observability of errors caused by 25% of Ruby software crashes. Our algorithm now recognizes well known exception messages and computes the fingerprint from the valuable data in those messages. This improvement is an important milestone in our automated error response roadmap.

To activate this enhancement on existing projects go to Settings → Advanced → Migrations. Otherwise, this is already enabled by default on newly created projects.

To see a list of these exception messages, please see the Ruby message patterns docs.

To activate the improvements on existing projects go to Settings → Advanced → Migrations. For new projects we activate them automatically.

We’re excited to announce our support for GitHub Actions with our new Rollbar Deploy GitHub Action. Teams using GitHub Actions for building their CI/CD pipeline can now easily send deploy information to Rollbar and respond to any new errors quickly.

With this action, you'll be able to -

• Automatically notify Rollbar of any new deploys from GitHub Actions
• Easily link deploy information to new versions to gain visibility into the changes being deployed, the person deploying the changes, the environment impacted, and the new errors that are being generated
• Respond to errors with detailed code context

To start using this GitHub Action, go here. For the best user experience, we recommend using our GitHub integration as well.

We're excited to introduce two new grouping enhancements that will reduce noise and improve the observability of errors:

• Reduced noise: the improved algorithm performs 10-40% better on grouping redundant occurrences.
• Better observability: the new algorithm uses the message for exceptions without stack frames to group in order to ensure that any truly unique errors are exposed.

To activate the enhancements on existing projects go to Settings → Advanced → Migrations. The enhancements are enabled by default on new projects.

To read more about this release, please see the grouping docs.

We're excited to introduce Git Blame for GitHub - to help you identify the last person to write or edit the line of code that caused the error, directly within the Rollbar UI.

In a nutshell, you can:

• See who the last author was to edit the line of code that caused the error
• Correlate when the code was written to the date and time of the item occurrence to help triage the error
• Get context on the history of the code and why, how the code was added
• Assign the error to the last author if needed

We're excited to introduce the new Rollbar user experience. We hope you like it as much as we’ve enjoyed building it for you! Here are some things to try:

• Monitor all microservices with one tool in one view. We've adopted powerful and consistent multi-project views across the entire user workflow. Get intelligent, real-time alerts on errors across microservices in a single view using our new multi-project filter. Whether you’re looking at the main dashboard, the Items view, or Versions, you’ll only see what you care about.

• Debug faster with a consistent workspace and powerful filters. Users now have their own personal workspace with powerful filters for projects, environments, and frameworks that persist across all views. Finding new errors is also faster and easier with improved Timeframe and ‘New or Reactivated’ filters.

• Get insights on data across multiple projects in one go. Run queries and correlate data across services with the multi-project functionality in RQL. Visualize the results and look for trends or anomalies easily with graphs.

For more information on how to switch to the new UX, head to our docs.

You can now create and resolve Work Items in Azure DevOps directly from Rollbar, making error monitoring and debugging even faster. No more switching between multiple tools and adding information manually!

With this integration, you can:

• Create an Azure DevOps Work Item directly from Rollbar, either directly or based on the ruleset (details below)
• View the stack trace in the Azure DevOps Work Item
• Auto-create tags and area paths, and view the Item in Rollbar with a single click
• Change the Work Item state automatically based on changes in Rollbar
• Resolve Azure DevOps Work Item automatically once resolved in Rollbar

For more information on the integration and instructions on setting it up, check out our integration guide here.

You can now write more complex queries in RQL using the new IF function.

Syntax:

IF(bool_expr, value_if_true, value_if_false)

For example, to chart Javascript error occurrences based on whether they happened immediately upon page load, shortly after load, a while after load, or long after load, you can use IF with the client.runtime_ms property as follows:

SELECT
  IF(client.runtime_ms < 1000, '1_load_to_1second',
    IF(client.runtime_ms < 60*1000, '2_1second_to_1minute',
      IF(client.runtime_ms < 60 * 60 * 1000, '3_1minute_to_1hour',
        IF(client.runtime_ms >= 60 * 60 * 1000, '4_1hour_and_up', 'unknown')))) time_on_page,
  COUNT(*)
FROM item_occurrence
WHERE framework = 'browser-js'
  AND timestamp > unix_timestamp() - 3600
GROUP BY 1
ORDER BY 1

Due to popular demand, you can now customize your file path with regex rules.

Differences in file paths often result in multiple items being created which lead to noisy item lists. If you run into this problem, there is now a solution - define regex rules to replace certain patterns of your file path with a common replacement.

For example, a file path such as /var/www/core3/releases/20190225T150625/src/services/automation/executor.py will change every time there is a new release due to different timestamps.

To avoid creating new items, you can go to Settings>Setup>Custom Fingerprinting and define a new regex rule under File Path Canonicalization.

This rule will create a new item in your list that generalizes file paths matching this pattern and therefore group occurrences more accurately.

We are currently looking for beta testers to try out this feature! If you’re interested, send us an email to support@rollbar.com or get in touch via the in-app chat. Please note that the option will only be available if we enable it for you.

You can learn more about this feature in the docs.

Occurrences from Android applications contain stack frames from the Android framework itself. Different Android versions and distributions can have some minor variations in the entry frames. We’ve now released a migration that upon activation will recognize a number of these variations and group related occurrences together.

To activate this you can go to Settings>Advanced>Migrations, tick the relevant checkbox, and push Save changes.

We recommend activating this migration for all Android projects. However, note that grouping migrations are not retrospective so you may receive some 'New Item' notifications initially.

Additionally, this option is activated by default for all new projects and it won't be visible.

If you’re using C#, you now have the option to exclude file names from the strings used for fingerprinting.

This option is enabled by default which means that we’ll take into account both the file name and the method of stack frames when fingerprinting. If you disable this option, we’ll only include the method. Please note that in the case of C#, the method contains the fully qualified class name, method name, and method signature, so disabling this option has a very low risk of overgrouping.

You can find this option by going to Settings>Setup>Custom Fingerprinting.

In case you want to exclude file names from multiple projects, you should disable this option in each project.

Please be aware that grouping changes are not retrospective. Disabling this option will cause your new errors to be grouped differently than before which will generate an initial flurry of 'New Item' notifications.
