bash for CVE-2014-6271 (shellshock)
$ check_shellshock ok: bash is secure against shellshock
You can pass an optional binary to check as the first argument, defaults to
bash in your
$ check_shellshock /bin/bash critical: /bin/bash is vulnerable to shellshock $ check_shellshock ./out/bin/bash ok: ./out/bin/bash is secure against shellshock
Check the age of the SmartOS kernel version
$ check_kernel_version warning: joyent_20140530T010428Z - 6 months old (195 days)
Pass arguments to modify
crit thresholds (respectively) in days
$ check_kernel_age 300 600 ok: joyent_20140530T010428Z - 6 months old (195 days)
Check for services in SMF that are not functioning properly
$ check_svcs ok: all services are online
kstat for hard errors - useful for identifying failing hardware
$ check_hard_errors ok: no hard errors found
Look for flapping services in SMF (rapidly restarting services)
$ check_flapping_services ok: no flapping services detected
If a service is flapping it will exit with critical status and print the service name(s)
$ check_flapping_services critical: flapping services found, svc:/application/voxer/dave-process:default
check_disk for memory usage using kstat to calculate used memory
$ check_mem -w 90 -c 95 ok: 7% used (warning=90%, critical=95%)|mem_used=303812608;mem_cap=4294967296
check_mem, but checks to see if you are over the memory allocated for your zone
$ check_mem_cap ok: nover is 0|nover=0
check_mem for disk utilization
$ check_disk_busy -w 90 -c 95 sd1 ok: disk 1% busy (warning=90%, critical=95%, disk=sd1)|disk_busy=1

you supply an invalid name, a list of all disks will be printed to
Count and alert on the number of running processes. The benefit of this check
over the built-in

$ ./check_proc_count -w 200 -c 400 ok: 37 processes running|proc_count=37
Look for running processes with an invalid or removed UID. This is usually
a sign that an automatically generated user from something like
been clobbered by configuration management software.
$ check_proc_owners critical: 2 processes found without valid UIDs $ check_proc_owners -v critical: 2 processes found without valid UIDs pid 47247 (uid 2033): sh pid 47251 (uid 2033): node server.js v
-v for verbose output, suitable for interactive use.
Run any script that outputs perf data at the end with a
