As part of the installation process, Chronosphere Telemetry Pipeline performs health checks on your behalf. If you encounter any issues when trying to install Telemetry Pipeline, Chronosphere recommends taking the following troubleshooting steps.
  1. Check for any warnings or errors in the output of the health checks that Telemetry Pipeline ran on your behalf.
  2. Confirm that you’ve met the networking and OS requirements for Telemetry Pipeline.
  3. Confirm that you’ve met the K3s requirements.
  4. Run the following command to disable FIPS mode, and then reboot: 
    fips-mode-setup --disable
  5. Run the following command to disable your firewall: 
    systemctl disable firewalld --now
  6. Verify that SELinux is either disabled or in permissive (not enforcing) mode.
  7. For Red Hat Enterprise Linux only, verify that your cryptographic policy is set to either default or legacy.
  8. For Red Hat Enterprise Linux only, run the following command to disable nm-cloud-setup, then reboot the node: 
    systemctl disable nm-cloud-setup.service nm-cloud-setup.timer
reboot
  9. Examine the following K3s network ranges to ensure they aren’t conflicting with your network settings:
    • Pods are allocated in the CIDR range 10.42.0.0/16. Use the INSTALL_CALYPTIA_CLUSTER_CIDR environment variable to override.
    • Services are allocated in the CIDR range 10.43.0.0/16. Use the INSTALL_CALYPTIA_SERVICE_CIDR environment variable to override.
    • Cluster DNS is set to 10.43.0.10. Use the INSTALL_CALYPTIA_CLUSTER_DNS environment variable to override.
    • The cluster domain suffix is set to cluster.local. Use the INSTALL_CALYPTIA_CLUSTER_DOMAIN environment variable to override.
    • Node ports are allocated in the range 30000 to 32767. Use the INSTALL_CALYPTIA_SERVICE_NODE_PORT_RANGE environment variable to override during installation.
  10. Examine your local /etc/resolv.conf configuration to ensure it isn’t using a DNS server or specifying any override that might conflict with K3s.
