Name	Description	Created by
check_kernel_version	Extracts the desired kernel version from ncm-query and compares it to the running kernel. It return a WARNING if they differ. We occasionally found nodes still running an old (vulnerable) kernel after deploying a kernel upgrade. This check helps to identify nodes that still need to be rebooted.	NIKHEF
check_ncd	It parses the ncd log files (/var/log/ncm/ncd.log*) and tries to find the latest run of NCD. The number of errors (CRITICAL) and warnings (WARNING) determine the result of the check.	NIKHEF
check_ncd	Does exactly the same but with different code :)	AUTH
check_service	a more generic script that checks if a particular service is indeed running. It wraps around init.d scripts. In the context of Quattor we run it against ncm-cdispd, to prevent nodes that don't respond to configuration changes.	NIKHEF
check_spma	It parses the spma log files (/var/log/spma.log*) and identifies the results of the latest run of SPMA. The SPMA result is returned as result of the check	AUTH
