Usage: $0 -H Rancher2Address -U user-token -P password [-S] -t checktype [-c cluster] [-p project] [-n namespace] [-w workload] [-o pod]
Options:
\t[ -H | --apihost ] Address of Rancher 2 API (e.g. rancher.example.com)
\t[ -U | --apiuser ] API username (Access Key)
\t[ -P | --apipass ] API password (Secret Key)
\t[ -S | --secure ] Use https instead of http
\t[ -s | --selfsigned ] Allow self-signed certificates
\t[ -t | --type ] Check type (see list below for available check types)
\t[ -c | --clustername ] Cluster name (for specific cluster check)
\t[ -p | --projectname ] Project name (for specific project check, needed for workload checks)
\t[ -n | --namespacename ] Namespace name (needed for specific workload or pod checks)
\t[ -w | --workloadname ] Workload name (for specific workload check)
\t[ -o | --podname ] Pod name (for specific pod check, this makes only sense if you use static pods)
\t[ -i | --ignore ] Comma-separated list of status(es) to ignore (node and workload check types), list of workload name(s) to ignore (workload check type) or certificate to ignore (local-certs check type)
\t[ --cpu-warn ] Exit with WARNING status if more than PERCENT of cpu capacity is used (supported check types: node, cluster)
\t[ --cpu-crit ] Exit with CRITICAL status if more than PERCENT of cpu capacity is used (supported check types: node, cluster)
\t[ --memory-warn ] Exit with WARNING status if more than PERCENT of mem capacity is used (supported check types: node, cluster)
\t[ --memory-crit ] Exit with CRITICAL status if more than PERCENT of mem capacity is used (supported check types: node, cluster)
\t[ --pods-warn ] Exit with WARNING status if more than PERCENT of pod capacity is used (supported check types: node, cluster)
\t[ --pods-crit ] Exit with CRITICAL status if more than PERCENT of pod capacity is used (supported check types: node, cluster)
\t[ --cert-warn ] Warning threshold in days to warn before a certificate expires (supported check types: local-certs)
\t[ -h | --help ] Help. I need somebody. Help. Not just anybody. Heeeeeelp!
Check Types:
\tinfo -> Informs about available clusters and projects and their API ID's. These ID's are needed for specific checks.
\tcluster -> Checks the current status of all clusters or of a specific cluster (defined with -c clusterid)
\tnode -> Checks the current status of nodes in all clusters or of nodes in a specific cluster (defined with -c clusterid)
\tproject -> Checks the current status of all projects or of a specific project (defined with -p projectid)
\tworkload -> Checks the current status of all or a specific (-w workloadname) workload within a project (-p projectid must be set!)
\tpod -> Checks the current status of all or a specific (-o podname -n namespace) pod within a project (-p projectid must be set!)
\tlocal-certs -> Checks the current status of all internal Rancher certificates (e.g. rancher-webhook) in local cluster under the System project (namespace: cattle-system)
