This script will output the Internet Connection Speed using speedtest-cli to Nagios.
|
||||||
|
|
||||||
|
You need to have installed speedtest-cli on your system first and ensured that it is
|
||||||
|
working by calling "speedtest --simple".
|
||||||
|
|
||||||
|
See here: https://github.com/sivel/speedtest-cli for info about speedtest-cli
|
||||||
|
|
||||||
|
First you MUST define the location of your speedtest install in the script or this will
|
||||||
|
not work.
|
||||||
|
|
||||||
|
The speedtest-cli can take some time to return its result. I recommend that you set the
|
||||||
|
service_check_timeout value in your main nagios.cfg to 120 to allow time for
|
||||||
|
this script to run; but test yourself and adjust accordingly.
|
||||||
|
|
||||||
|
You also need to have access to bc on your system for this script to work and that it
|
||||||
|
exists in your path.
|
||||||
|
|
||||||
|
Your warning levels must be higher than your critical levels for both upload and download.
|
||||||
|
|
||||||
|
Performance Data will output upload and download speed against matching warning and
|
||||||
|
critical levels.
