I recently migrated from OpenHAB 2 to OpenHAB 4 on my Raspberry Pi and decided to set up Grafana along with InfluxDB using the openhabian-config tool. Everything seemed to go smoothly during the installation, but I’ve encountered a recurring issue where Grafana crashes and restarts every 2 minutes. Here’s what I’ve observed and tried so far:
Observations
-
Log Analysis: I reviewed the Grafana logs and noticed an error related to an illegal instruction (
SIGILL
). This typically indicates that the CPU encountered an instruction it couldn’t execute, which could be due to architecture mismatches or corrupted binaries. -
Resource Usage: My Raspberry Pi is a 4th generation model with 2GB of RAM. While Grafana is running, the CPU usage doesn’t seem excessively high, but the memory usage fluctuates significantly.
-
Dependencies: I ensured that all dependencies for Grafana and InfluxDB were properly installed and up-to-date.
Troubleshooting Steps
-
Updated Grafana: I tried updating Grafana to the latest stable version available in the repositories. However, the issue persisted.
-
Checked Architecture Compatibility: I verified that the Grafana package is compatible with the ARM architecture of the Raspberry Pi. It appears to be, but I’m still unsure if this is the root cause.
-
Reinstalled Grafana: As a last resort, I completely uninstalled Grafana and InfluxDB, then reinstalled them from scratch. Unfortunately, the problem remains.
-
Monitoring System Resources: I started monitoring the system resources more closely using
top
andhtop
. I noticed that when Grafana crashes, the memory usage spikes temporarily, but it’s unclear if this is a cause or symptom.
Questions and Requests
- Has anyone else experienced similar issues with Grafana on a Raspberry Pi?
- Are there specific configurations or optimizations I should implement to stabilize Grafana?
- Could the issue be related to the interaction between Grafana and InfluxDB, or is it more likely a standalone Grafana problem?
I appreciate any advice or insights you can provide to help resolve this issue. Grafana is a valuable tool for visualizing my home automation data, and I’m eager to get it working smoothly again.
