Remote Agent Expired

If BlazeMeter is unable to communicate with your Radar agent regularly, test results that attempt to use that agent will be marked as Remote Agent Expired, and will be indicated in orange in the Dashboard, Latest Test Results, and Test Result progress bars.

expired results

Test runs that cannot be completed due to issues with remote agents as well as system errors are not counted towards test metrics such as success ratio, average response time, and more.


Here are some steps you can follow to help debug this issue:

  • Make sure that you're running the latest version of the agent. You can check the agent version by running it with the --version flag, and you can download the latest version here.
  • Ensure that your agent is actively communicating with BlazeMeter by inspecting the output of the agent. You can use the --verbose flag when running the agent to get a more detailed output.
  • If the agent is unable to communicate with BlazeMeter, verify it's general ability to make outbound HTTPS requests to and Check our Agent Connection Errors and HTTP/HTTPS Proxy Setup articles for more information.
  • If the agent is successfully connecting to BlazeMeter, but you're seeing intermittent issues with your test runs, two common causes for this are:
    • If the agent output includes the following message: [ERROR] No open slots for work, that means your agent is trying to run more tests than it can handle. To fix this, update your configuration file to use threads=50.
    • If you're not seeing the error message above in the agent output, the issue might be that the agent is having trouble connecting to BlazeMeter in a timely manner. This could be caused by multiple reasons, such as an increased latency in the server's network, for example. To fix this, update your configuration file to use disconnect-timeout=15. That setting determines how long BlazeMeter will wait before considering the agent offline, so increasing the timeout can potentially fix the issue. The only drawback for increasing that value is that when you turn off the agent, the UI will take longer before showing it as offline.

Monitor Remote Agent Health

You can monitor the health of your remote agents by creating a Radar Agent Monitoring test, or by using webhooks:

  • Create a Radar Agent Monitoring test
  • Use advanced webhooks: BlazeMeter's advanced webhooks supports an agent_expired parameter, which indicates the status of the agent for the test run:
    • true indicates that the agent is expired
    • null indicates that the agent is available, or if a default BlazeMeter API Monitoring location is used
