Collector v71 Release Notes

The Windows collector version 71 is now available. Notable improvements include:

  • Stability improvements for the AppAccess Service.
  • Fixed an issue that could show up at installation time if network connectivity is not available during the startup process.
  • If there are issues at startup, the collector will exit and generate an Event Log explaining the problem.
  • Handling of a random problem that could disable log collection.


  • Improved statistics when using overlapped sockets.
  • Event Log collection will include the Event ID.

New Features, Fixes, and Select Availability for Beta Features

Hello AppFirsters,

We’d like to wish you a happy belated Valentine’s Day and share the new features and fixes we made this week! Here’s the rundown with descriptions below:

Updates to both Linux and Windows collectors, updates to our Alerting System, Stolen Time Measurements, and two limited beta features.

  • Linux Collector Version 55 available now! We made significant improvements in the thread data collection algorithm so make sure you update your collector.
  • Windows Collector Version 40 available now! We made a fix for an AppAccess Service crash bug, a fix for losing shared memory thread space by doubling adding threads, and a fix to NOT install into system32 and explorer.exe by default.
  • Updates to our Alerting System. Previously, high response time alerts for tenants with many collectors would cause the responder to crash and alerting to slow down. Alerting would ask for data for all the tenant’s collectors, instead of specific data it needed. So we modified the way alerting does the root cause algorithm for high response time alerts so it only asks for what it needs.
  • Stolen Time Measurements. You can view the percentage of Stolen Time in the Server widget under System Resources. About Stolen Time:
Essentially, the steal time cycle counts the amount of time that your VM is ready to run but could not run due to other VM’s competing for the CPU. This is a particularly relevant statistic to think about when you are using a cloud service provider. With cloud service providers you don’t control the hypervisor (as an enterprise customer would in a traditional datacenter). As a result, you don’t know how much the hypervisor is oversubscribed nor do you have insight or control into the amount of resources that other VM’s are taking from your compute requirements.

New Beta Features – Limited Availability!!!

We’re releasing two new beta features for a select number of people. StatsD Business Metrics and a new and improved Data Flow. StatsD will allow you to push your custom business data to our backend and can be graphed and correlated with the other data sources we collect. Our new Data Flow is in the first phase of Transaction Tracing.

If you’re interested in testing out either of these beta features, you can contact us on Skype at appfirsthelp or at

Hope you all enjoy!
