Health check would normally depends on what an enterprise decides to be tracked/checked preiodically. So, any abnormalities during these checks would be triggered as an alarm and needs to be addressed. These health checks would differ from organization to another and also standards may vary. Generally, we could consider these checks which falls under health check such as:
- Mounted File Systems
- Read-only File System If Any
- File Systems Disk Usage
- Inode Usage
- Zombie Processes If Found
- RAM Utilization
- SWAP Utilization
- Processor Utilization
- Current Load Average
.... many more. The community members might have a different perception about this.
Hi,
There is no specific steps, it would depend on end user requirements or as per company standards. Most of such tasks could be implemented using shell scripts, also there are a few open source tools which could also be used. One such one is Xsos https://access.redhat.com/discussions/469323, please check this.
Such health checks would be grouped under 'monitoring' tree hence, we could use tools available in market which are open soruce such as Nagios, cacti, ganlia,Icinga, Pandora FMS etc,. You may be interested to view this discussion thread as well https://access.redhat.com/discussions/3170001
