Voxer Nagios Plugins

Plugins for nagios used by Voxer, made specifically for SmartOS

Plugins

check_shellshock

Check 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 $PATH

$ 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_kernel_age

Check the age of the SmartOS kernel version

$ check_kernel_version
warning: joyent_20140530T010428Z - 6 months old (195 days)

Pass arguments to modify warn and crit thresholds (respectively) in days

$ check_kernel_age 300 600
ok: joyent_20140530T010428Z - 6 months old (195 days)

check_svcs

Check for services in SMF that are not functioning properly

$ check_svcs
ok: all services are online

check_hard_errors

Check kstat for hard errors - useful for identifying failing hardware

$ check_hard_errors
ok: no hard errors found

check_flapping_services

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_mem

Like 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_cap

Like 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_disk_busy

Like 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

The final argument is the disk name to check (defaults to sd1), if you supply an invalid name, a list of all disks will be printed to stderr.

check_proc_count

Count and alert on the number of running processes. The benefit of this check over the built-in check_proc is that this script only does process count, so it is fast, and also does not require escalated privileges.

$ ./check_proc_count -w 200 -c 400
ok: 37 processes running|proc_count=37

check_proc_owners

Look for running processes with an invalid or removed UID. This is usually a sign that an automatically generated user from something like pkgin has 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

Supply -v for verbose output, suitable for interactive use.

Notes

Run any script that outputs perf data at the end with a -n switch to suppress that output.
