Avoid using log streaming for persistent log transmission to internal or third-party log retention services. If you require this feature, contact your Acquia account manager to purchase Acquia’s Log forwarding service.
Besides downloading log files from the Cloud Platform interface or accessing logs using command-line tools, you can also stream logs in real time using the Cloud Platform interface on the Applications > [Environment] > Logs page. The Logs page stream shows log entries from all the logs of an environment at once. In contrast, each of the log files you can download shows a single log from an infrastructure (aside from the Drupal watchdog log and the MySQL slow query log).
Update your Node.js application within the error-handling code so that the code can capture error information and display logs and error messages in log streaming. Node.js applications that capture logs through console.log() and error messages through console.error() can provide effective monitoring and troubleshooting.
There are several methods you can use to modify which log entries are streamed:
Click Stream to select which logs are the source of log entries to be streamed. By default, the PHP error and Apache error logs are enabled.
To download a log file, select Logs > Download. For more information, see Downloading active log files.
If the rate of messages goes beyond 500 messages per second during log streaming for an environment, you might experience delays in your stream. This lag might be caused due to latency in the network. However, the system does not drop any messages.
Log entries are displayed with different colored bars at the left margin:
| Log source | Bar color |
|---|---|
| Apache error | Red |
| Apache request | Yellow |
| Balancer request | Green |
| Drupal request | Yellow |
| MySQL slow query | Red |
| Node.js error | Red |
| PHP error | Red |
| Varnish® request | Green |
In addition to streaming logs on the Logs page, you can use the Logstream Ruby gem, which provides a client-side API library and command-line interface. Learn more about how to install and use Logstream.
