Last updated - 21 November, 2025
Issues may occur when configuring Google Cloud Platform (GCP) log ingestion for LogicMonitor. For example, you may experience compatibility problems with the GCP log forwarder.
GCP Log Forwarder Fails to Forward Logs
If you set up your LogicMonitor environment to ingest logs from GCP, the GCP log forwarder my fail to forward logs with the following error:
ERROR: Error installing fluentd: The last version of yajl-ruby (~> 1.0) to support your Ruby & RubyGems was 1.4.1. Try installing it with `gem install yajl-ruby -v 1.4.1` and then running the current command again yajl-ruby requires Ruby version >= 2.6.0. The current ruby version is 2.5.0.sudo: fluentd: command not found
The error occurs because Debian 10 is no longer compatible with Ruby 2.5.0 due to its outdated system libraries. To fix the issue, you must do one of the following:
- Upgrade the operating system to Debian 11 or Debian 12, since Debian 10 does not support Ruby 2.6.0 or later
- Manually install Ruby 2.6.0 or later
