Why Your RHEL Servers Need Regular Health Checks

Red Hat Enterprise Linux powers mission-critical workloads across enterprises worldwide — from SAP HANA databases to Kubernetes clusters. Regular health checks catch issues before they cause downtime:

Disk filling up silently — catch capacity warnings before /var or /tmp hits 100%
Failed systemd services — services crash and nobody notices until users complain
SELinux in permissive mode — security policy not enforcing, leaving the server vulnerable
Kernel parameter drift — sysctl values changed during troubleshooting and never reverted
NTP clock drift — time sync issues causing authentication failures and log correlation problems

RHEL-Specific Diagnostics

SELinux Deep Analysis Enforcement mode, AVC denials, boolean settings, policy version, file context issues

YUM/DNF Package Health Pending security updates, orphaned packages, repository health, GPG key validation

Subscription Status subscription-manager output, entitlement status, content access mode

Firewalld Analysis Active zones, allowed services, rich rules, port forwarding configuration

RHEL Kernel Tuning vm.swappiness, transparent hugepages, I/O scheduler, network buffer sizes

Performance Counters Load average trends, CPU steal time (VMs), memory pressure, NUMA topology

LVM & XFS Health Volume group utilization, thin pool monitoring, XFS fragmentation, multipath status

Systemd Service Audit Failed units, masked services, boot target analysis, timer units

Generate a Health Check on RHEL


                # Install sos package (usually pre-installed on RHEL)

                $ sudo yum install sos


                # RHEL 7

                $ sudo sosreport


                # RHEL 8 / 9 (sos has been updated)

                $ sudo sos report


                # Output: /var/tmp/sosreport-*.tar.xz

                # Upload this file to linuxdiag.org
