Website and keyword monitors
Check that a page answers, and that it says what it should.
A website monitor requests your address and checks the answer. By default a status code from 200 to 399 counts as up. You can change the request method, send headers, and add basic or bearer authentication. Credentials and secret headers are stored encrypted and are never shown again.
Redirects and timeouts
Redirects are followed, up to ten hops. The timeout covers the whole request, including DNS, connecting and reading the page. You can choose 5 to 60 seconds, shorter than the check interval.
Keyword checks
A keyword monitor does the same and also looks for a word in the first part of the page. Choose whether the word must exist or must not exist, and whether the match is case sensitive.
IPv4 and IPv6
You can force IPv4 or IPv6 if you want to check one family specifically.
