Linux Troubleshooting Cheatsheet -🐧 1. How to Check Disk Space Usage Answer: Use df -h to view disk usage by mounted filesystems. For directory-level details, run du -sh /path/to/directory. Clean up old logs, unused packages, or large files with tools like ncdu for interactive analysis. 2. Service Fails to Start Answer: Check status with systemctl status service-name. View logs via journalctl -u service-name --since "10 minutes ago". Ensure dependencies are installed and configuration files (e.g., /etc/service-name/config.conf) are correct. 3. Network Connectivity Issues Answer: - Test connectivity: ping 8.8.8.8 (Google DNS). - Check routes: ip route or traceroute google.com. - Verify DNS: dig google.com or nslookup google.com. - Inspect interfaces: ip a or ifconfig. Restart networking with systemctl restart NetworkManager (or networkd). 4. "Permission Denied" Errors Answer: - Check permissions: ls -l /path/to/file. - Modify permissions: chmod 755 file or chown user:group file. - If SELinux/AppArmor blocks access, check logs (/var/log/audit/audit.log) or temporarily disable with setenforce 0. 5. Terminating Unresponsive Processes Answer: - Find PID: ps aux | grep process-name or top. - Kill process: kill -9 PID or pkill process-name. - Force-kill all instances: killall -9 process-name. 6. System Fails to Boot Answer: - Boot into recovery mode (GRUB menu) and check logs (/var/log/boot.log or journalctl -b). - Repair filesystems: fsck /dev/sdX. - Reinstall bootloader (GRUB): grub-install /dev/sdX. 7. "No Space Left on Device" Despite Free Space Answer: - Check inode usage: df -i. - Delete small, numerous files (e.g., temporary files) to free inodes. 8. DNS Resolution Failures Answer: - Verify DNS config: cat /etc/resolv.conf. - Test DNS server: dig @8.8.8.8 google.com. - Restart DNS resolver: systemctl restart systemd-resolved. 9. High CPU/Memory Usage Answer: - Identify resource hogs: top, htop, or vmstat 2. - Kill problematic processes or optimize applications. Check for memory leaks with free -h. 10. SSH Connection Refused Answer: - Ensure SSH service runs: systemctl status sshd. - Check firewall rules: ufw status or iptables -L. - Verify SSH port (default: 22) is open and accessible. 11. Filesystem Corruption Answer: - Unmount the disk: umount /dev/sdX. - Run fsck /dev/sdX to repair. Backup critical data first. For root FS, boot from a live USB. 12. Cron Jobs Not Executing Answer: - Check cron logs: grep CRON /var/log/syslog. - Ensure the cron service is running: systemctl status cron. - Validate syntax and user permissions in /etc/crontab or user crontabs (crontab -e).

“Incident report : Incident resolved in 25 minutes with zero impact on SLA performance” Here’s what happened: Our devops team received several automated anomaly alerts coming from uncorrelated resources in our Azure test environment. At first, it seemed unrelated, but digging deeper, we realized the common thread was data ingestion. Impact: data ingestion was about to stop for one monitored environment in test. From early anomaly triggered: 1️⃣ We spent 10 minutes analyzing the alerts to identify abnormal behavior in specific Azure appservices. 2️⃣ We found the root cause—an issue with data replication—in another 10 minutes. 3️⃣ With this clue a retry policy issue was applied in just 5 minutes. 25 minutes in total - with zero minutes of disruption, but a 7 minute window of poor latency. Without clear and automated insight into our system, this could have taken hours and days to detect—time that might have impacted operations or even clients (if this was not in our test environment). Here’s the key takeaway: having a comprehensive view of your data and systems matters. It’s not just about speed; it’s about avoiding the ripple effects of delayed resolutions. 🚀 Lessons we learned from this: - Prioritize comprehensive automated and pro-active monitoring across all your data to connect the dots quickly. - Care about IT hygiene and always investigate the “common contact points” when troubleshooting multiple issues. - Plan for next steps to use the knowledge for even faster remediation in the future Have you experienced similar challenges with system visibility or troubleshooting? How do you approach solving issues under pressure?  Where do you feel the pain?  Not enough data, too manual or are you reactive - looking at logs? 🙈 📣 Let’s share strategies in the comments—this is how we learn from each other! Here is how the history of the alert developing over time - involving more resources and changing in criticality status!
