- IPv4 or IPv6
- TLS or not
- www or not
Some permutations will result in a page loading. Others may result in a redirect. All permutations need testing.
Websites to be tested are defined in a beautiful YAML format.
It produces a nice report and can pass the report to a local mail-server if you want.
Here's some example YAML, that tests Free Software UK:
- name: Free Software UK
expected string: Free Software UK
canonical address: https://www.freesoftwareuk.org.uk/
urls:
- url: www.freesoftwareuk.org.uk
tests:
- action: return string
protocols:
- TLS
- action: redirect
protocols:
- no-TLS
- url: freesoftwareuk.org.uk
tests:
- action: redirect
protocols:
- TLS
- no-TLS
This translates into 8 checks and produces the following output:
IPv4, does "www.freesoftwareuk.org.uk" return string over "TLS"? Test Success! IPv6, does "www.freesoftwareuk.org.uk" return string over "TLS"? Test Success! IPv4, does "www.freesoftwareuk.org.uk" redirect over "no-TLS"? Test Success! IPv6, does "www.freesoftwareuk.org.uk" redirect over "no-TLS"? Test Success! IPv4, does "freesoftwareuk.org.uk" redirect over "TLS"? Test Success! IPv6, does "freesoftwareuk.org.uk" redirect over "TLS"? Test Success! IPv4, does "freesoftwareuk.org.uk" redirect over "no-TLS"? Test Success! IPv6, does "freesoftwareuk.org.uk" redirect over "no-TLS"? Test Success! Summary: 8 tests passed 0 tests failed
To monitor all 10 of my websites like this means 64 checks. To get this many checks with UptimeRobot would require a Pro plan and it wouldn't allow me to test IPv4 vs 6. Rival service Pingdom can do IPv4 or 6 but this many checks would require an "Advanced" plan for £48 GBP per month!
If you don't like YAML this probably isn't for you because it's wholly based on YAML.
Dependencies are:
- python3
- python3-yaml
- python3-pycurl
To find out the options please run:
./xylositemonitor.py --help
I use it as a cron job on a dedicated monitoring server:
25 5 * * * /usr/local/bin/xylositemonitor.py --annotation 'SiteMonitor daily' --mailto joseph@xylon.me.uk 33 * * * * /usr/local/bin/xylositemonitor.py --annotation 'SiteMonitor hourly' --mailto joseph@xylon.me.uk --email-only-on-fail
This way I get an email every day, usually telling me all tests passed. And there's also an hourly check which only sends an email on error.
